HSKLord vs Hack Chinese: HSK Vocabulary Apps Compared (2026)

Overview: Two Niche HSK Vocabulary Apps

If you are searching for a Hack Chinese review or evaluating a Hack Chinese alternative, you have probably already ruled out the general-purpose language apps. Apps like Duolingo, HelloChinese, and Rosetta Stone try to cover everything from grammar to pronunciation to cultural context. That breadth comes at a cost: none of them are particularly good at the one thing HSK test-takers need most, which is systematic vocabulary acquisition organized by HSK level.

HSKLord and Hack Chinese both occupy a different niche. They are purpose-built for HSK vocabulary learning. They do not try to teach you conversational Chinese from scratch or walk you through grammar drills. Instead, they focus on helping you learn, retain, and review the specific words required by the HSK exam framework. This makes them fundamentally different from most Chinese learning apps on the market, and it is why comparing them head-to-head is more useful than comparing either one to a general language app.

Both apps use spaced repetition as their core learning mechanism. Both organize vocabulary by HSK level. Both are designed for learners who already know what the HSK is and are actively preparing for it. The differences lie in their approaches to how vocabulary is presented, what supplementary features they include, how they handle the transition to HSK 3.0, and what it costs to use them.

What Makes These Apps Similar

Before diving into the differences, it is worth understanding why these two apps are the most direct competitors in the HSK vocabulary space. They share several foundational characteristics that set them apart from the broader Chinese learning app market.

Both are HSK-specific. Unlike general Chinese apps that organize content by theme or conversational scenario, both HSKLord and Hack Chinese organize their vocabulary lists around the official HSK level structure. When you open either app, you select an HSK level and study the words required for that level. This alignment with the exam framework means you are always studying material that directly maps to what you will be tested on.

Both use spaced repetition. The core study loop in both apps is built on SRS principles. You encounter a word, rate how well you know it, and the algorithm schedules your next review at an optimal interval. This is the gold standard for vocabulary retention, and both apps implement it as a central feature rather than a secondary add-on. If you are familiar with Anki's approach to Chinese flashcards, both HSKLord and Hack Chinese offer a more polished, HSK-tailored version of that experience.

Both are vocabulary-focused. Neither app tries to be a complete Chinese course. They do not include grammar lessons, cultural notes, or extended reading passages. Their value proposition is straightforward: help you learn and retain the vocabulary you need for the HSK. This focused approach is a strength for learners who already have a study plan and need an efficient tool for the vocabulary component.

Hack Chinese's Approach: Sentence-Based Learning

Hack Chinese has been in the HSK vocabulary space for several years and has built a loyal user base. Its core differentiator is a sentence-based learning model. Rather than presenting isolated words on flashcards, Hack Chinese embeds each word within a full sentence. The idea is that seeing a word in context helps you understand not just its meaning but how it is actually used in natural Chinese.

This approach has genuine pedagogical merit. Research on vocabulary acquisition consistently shows that contextual learning produces deeper understanding than rote memorization of isolated words. When you see a word like 效率 (xiào lü, efficiency) used in a sentence about workplace productivity, you start to internalize the kinds of situations where that word naturally appears. Over time, this contextual exposure helps bridge the gap between recognizing a word on a flashcard and actually producing it in conversation or writing.

Hack Chinese also includes a dedicated tone trainer. Tones are one of the most challenging aspects of Mandarin for non-native speakers, and having a focused tool for tone practice is a meaningful feature. The tone trainer helps you distinguish between the four tones (plus the neutral tone) through audio exercises, which is particularly valuable for learners who are preparing for the listening section of the HSK.

Another strength of Hack Chinese is its custom word list functionality. Beyond the standard HSK word lists, you can create your own lists from any source — textbooks, articles, or vocabulary you encounter in daily life. This flexibility is useful for advanced learners who have moved beyond the structured HSK levels and want to continue using the same SRS system for non-HSK vocabulary.

Hack Chinese tracks your progress with a percentage-based system that shows what proportion of each HSK level you have learned and how well you are retaining it. The interface is clean and functional, and the app has a straightforward workflow that does not overwhelm you with unnecessary features.

HSKLord's Approach: Pure SRS with Visual Progress

HSKLord takes a different approach. Instead of embedding vocabulary in sentences, HSKLord focuses on maximizing the efficiency of the SRS review cycle. Every design decision in the app is oriented toward helping you learn the most words in the least time while maintaining strong long-term retention. The flashcard interface is clean and distraction-free, presenting you with the simplified character, pinyin, English meaning, and audio pronunciation for each word.

One of HSKLord's most distinctive features is its visual progress tracking system. Rather than a simple percentage bar, HSKLord provides dashboards that show your mastery across all HSK levels simultaneously. You can see at a glance how many words you have learned at each level, which words are coming up for review, and where your retention is weakest. This visual feedback loop is motivating and helps you make informed decisions about where to focus your study time.

The biggest technical advantage HSKLord holds right now is full HSK 3.0 support. The app has already been updated with the complete HSK 3.0 vocabulary lists across all levels, including the expanded word counts and the new level structure. This is critical for learners who are preparing for the new exam format. Hack Chinese, as of early 2026, has not yet released HSK 3.0 content, which means its vocabulary lists still follow the older HSK 2.0 framework.

HSKLord covers HSK 1 through HSK 6 under the traditional framework, plus the full HSK 3.0 vocabulary, giving you access to over 5,000 words. Each word includes audio pronunciation, which you hear during your flashcard reviews. While this is not a standalone tone trainer like Hack Chinese offers, hearing correct pronunciation during every review session reinforces tonal accuracy as a natural part of the learning process.

The app's UI is modern and responsive, designed for extended study sessions without eye strain. Dark mode, keyboard shortcuts, and a streamlined review flow all contribute to an experience that feels fast and focused. HSKLord also integrates tools like a placement test and a study calculator that help you plan your preparation timeline based on your target HSK level and exam date.

HSKLord vs Hack Chinese: Feature Comparison

The following table summarizes the key differences between the two apps. Both are strong products in the HSK vocabulary niche, but they make different trade-offs that matter depending on your priorities.

Key Differences That Matter

Looking at the comparison table, several differences stand out as genuinely impactful for your learning experience. These are the factors that should drive your decision, rather than minor feature variations.

HSK 3.0 Readiness

This is arguably the most time-sensitive difference. The new HSK 3.0 framework introduces significant changes to the vocabulary requirements at every level. If you are preparing for an HSK exam in 2026, you need study materials that reflect the new word lists. HSKLord has already implemented full HSK 3.0 support, meaning every word in the updated framework is available in the app's SRS system. Hack Chinese is still operating on the HSK 2.0 vocabulary lists. This does not mean Hack Chinese is useless for current learners — there is substantial overlap between the old and new word lists — but it does mean you may be missing vocabulary that appears on the new exam.

Learning Philosophy: Words vs. Sentences

Hack Chinese's sentence-based approach and HSKLord's word-focused approach represent two legitimate schools of thought in vocabulary acquisition. Sentence-based learning gives you richer context but requires more time per review item. Word-focused SRS maximizes the number of words you can review in a given time period, which is particularly valuable when you are trying to cover the full vocabulary list for an upcoming exam. Neither is wrong. The question is whether you prioritize depth of understanding for each word or breadth of coverage across the entire HSK vocabulary.

Progress Visibility

HSKLord's visual dashboards provide a significantly more detailed view of your progress than Hack Chinese's percentage-based tracking. Being able to see exactly which words are due for review, which ones you are struggling with, and how your retention rates are trending across multiple HSK levels gives you much more control over your study strategy. This matters most for intermediate and advanced learners who are managing vocabulary across several HSK levels simultaneously. If you are studying HSK 4 while maintaining your HSK 3 vocabulary, visual dashboards help you balance the workload.

Tone Training

Hack Chinese has a clear edge here with its dedicated tone trainer. While HSKLord includes audio pronunciation with every flashcard — which passively reinforces tonal accuracy during reviews — Hack Chinese's standalone tone training tool provides focused, active practice on tone discrimination. If tones are a particular weakness for you, this feature alone could tip the balance toward Hack Chinese. However, if you are already comfortable with tones or are supplementing with other pronunciation resources, the passive audio in HSKLord's flashcard reviews may be sufficient.

Pricing Comparison

Pricing is one of the starkest differences between these two apps, and it goes beyond the dollar amount. The real difference is in the purchasing model.

Hack Chinese requires a paid subscription from the moment you start using the app. There is no free tier and no free trial period. You are paying before you have had any chance to evaluate whether the app fits your learning style. Hack Chinese offers monthly and annual subscription plans, with the annual plan providing a meaningful discount. The pricing is competitive within the language learning app market, but the complete absence of a trial period is a friction point for learners who want to compare options before committing.

HSKLord offers a 30-day free trial with full access to all features. During the trial, you can use every HSK level, access all HSK 3.0 vocabulary, run unlimited SRS reviews, and explore the full progress tracking system. No credit card is required to sign up. After the trial, HSKLord transitions to a subscription model. This approach lets you build a meaningful study habit and evaluate the app's effectiveness before spending anything.

The practical impact of this difference is significant. Thirty days is enough time to work through a substantial portion of an HSK level's vocabulary and see whether the SRS system is producing results for you. It is also enough time to compare HSKLord directly with Hack Chinese (if you subscribe to both simultaneously) and make an informed choice about which app to continue with long-term.

Who Should Use Hack Chinese

Hack Chinese is a strong choice for a specific type of learner. If the following descriptions match your situation, Hack Chinese may be the better fit for you.

• You value sentence context highly. If you find that learning words in isolation does not stick for you, and you need to see words used in natural sentences to really internalize them, Hack Chinese's sentence-based approach is built specifically for this learning style.
• Tone training is a priority. If tones remain a significant challenge and you want a dedicated tool for tone discrimination practice within your vocabulary app, Hack Chinese's tone trainer is a genuine differentiator.
• You want custom word lists beyond HSK. If you are an advanced learner who has moved past the structured HSK levels and wants to build custom vocabulary lists from your own reading or coursework, Hack Chinese's custom list feature supports this workflow well.
• You are studying HSK under the 2.0 framework. If you are taking an HSK exam before the 3.0 transition and do not need the updated vocabulary lists, the HSK 3.0 gap in Hack Chinese does not affect you.
• You are comfortable committing financially upfront. If you have already decided you want a dedicated HSK vocabulary app and do not need a trial period to make that decision, the lack of a free trial is not a barrier.

Who Should Use HSKLord

HSKLord is designed for learners who want maximum efficiency and modern tooling for their HSK vocabulary preparation. It is the right choice if the following points resonate with you.

• You are preparing for HSK 3.0. If your target exam is under the new HSK 3.0 framework, HSKLord's full support for the updated vocabulary is a decisive advantage. Studying from outdated word lists risks leaving gaps in your preparation.
• You want to try before you pay. HSKLord's 30-day free trial lets you build a real study habit and evaluate the app's effectiveness before any financial commitment. This is especially valuable if you are comparing multiple apps.
• Visual progress tracking motivates you. If you are the type of learner who is motivated by seeing clear, visual evidence of your progress across multiple HSK levels, HSKLord's dashboard system is significantly more detailed than what Hack Chinese offers.
• You prioritize review speed and volume. HSKLord's word-focused flashcard approach lets you review more words per session than a sentence-based system. If you have limited study time and want to maximize the number of words you cover, this efficiency matters.
• You want a modern, polished interface. HSKLord's UI is designed for the current era of web applications, with dark mode, responsive design, and a fast review flow that minimizes friction during study sessions.
• You want integrated study planning. Tools like the placement test and study calculator help you plan your entire HSK preparation journey within a single platform.

Our Take

Both HSKLord and Hack Chinese are serious tools built by people who understand the HSK exam and the specific challenges of Chinese vocabulary acquisition. This is not a comparison between a good app and a bad app. It is a comparison between two good apps with different strengths.

Hack Chinese's sentence-based approach is genuinely valuable for learners who want contextual depth alongside their vocabulary building. Its tone trainer is a feature that no direct competitor currently matches. And its years of presence in the market mean it has a mature, stable product with a proven track record.

That said, we believe HSKLord offers the stronger overall package for most HSK learners in 2026, for three specific reasons.

First, HSK 3.0 readiness. The transition to HSK 3.0 is happening now. If you are studying for an HSK exam this year or next year, you need materials that reflect the new vocabulary requirements. HSKLord is already there; Hack Chinese is not.

Second, the free trial. Being able to use a product for 30 days before paying is not just a pricing advantage — it is a learning advantage. Many learners try an app, use it for a week, and realize it does not fit their study style. With HSKLord, that exploration costs you nothing. With Hack Chinese, it costs a month's subscription. The trial also lets you compare both apps side-by-side by signing up for HSKLord's free trial while using a Hack Chinese subscription, and keeping whichever works better for you.

Third, visual progress tracking. The ability to see exactly where you stand across all HSK levels, which words need attention, and how your retention is trending over time transforms vocabulary study from a vague grind into a measurable, manageable process. This is the kind of feature that keeps learners consistent over the months it takes to prepare for an HSK exam.

If you are primarily interested in sentence-based learning or dedicated tone training, Hack Chinese remains a solid choice. But if you want HSK 3.0 vocabulary, efficient SRS reviews, visual progress tracking, and the ability to try everything free for 30 days, HSKLord is the app to start with.
