Anki is brilliant. Anyone who has stuck with it for more than a few weeks will tell you this. The spaced repetition algorithm does exactly what it promises, surfacing cards at the precise moment before you are about to forget them. It is efficient, customizable, and backed by decades of cognitive science research. For many language learners, Anki represents the gold standard of vocabulary acquisition.
So why do so many people quit?
I have watched friends download Anki with genuine enthusiasm, spend an entire weekend building elaborate decks with audio clips and image mnemonics, and then abandon the app within a month. The pattern repeats itself constantly. Someone discovers Anki, recognizes its potential, invests serious time into setting it up, and then disappears from the review queue. The reasons vary, but they all trace back to the same fundamental problem: Anki requires you to be your own teacher, curriculum designer, and technical support team.
The friction starts before you even learn your first word. You need to decide whether to create your own deck or download a shared one. Creating your own feels like the right choice because you can tailor the content to your specific needs and interests. But creating quality cards takes an enormous amount of time. You need to find example sentences, source audio pronunciation, add images for context, and format everything consistently. A single well-made card might take five minutes to construct properly. Multiply that by the hundreds or thousands of cards you need for conversational fluency, and the time investment becomes staggering.
Downloading shared decks seems like a shortcut, but it introduces its own problems. Most shared decks contain isolated vocabulary words rather than contextual sentences. You end up memorizing that “perro” means “dog” without understanding how the word functions in actual speech. Other decks might include hundreds of obscure terms you will never use while skipping common phrases you need daily. You spend time reviewing cards that do not serve your goals, which drains motivation faster than any difficult grammar concept ever could.
Then there are the settings. Anki offers dozens of configuration options for interval modifiers, ease factors, new card limits, and learning steps. Each setting affects your review queue in ways that are difficult to predict. Change one value and suddenly you have three hundred cards due tomorrow instead of fifty. Spend hours watching tutorial videos trying to understand what “interval modifier” actually does, only to realize that the optimal settings depend on your personal memory retention patterns, which you cannot know until you have been using the app for months.
I went through this myself. I spent an entire evening tweaking my Anki settings, convinced that finding the perfect configuration would unlock effortless learning. I read forum posts debating the merits of different scheduling algorithms. I experimented with leech thresholds and max reviews per day. All of this technical optimization felt productive in the moment, but it was really just procrastination disguised as preparation. I was avoiding the actual work of learning by obsessing over the tools.
The irony is that Anki works best when you remove as much friction as possible from the card creation process. But removing friction requires either accepting low-quality cards or investing significant upfront time in automation tools and add-ons. You can install plugins that pull audio from text-to-speech engines, but then you need to configure those plugins and deal with robotic pronunciation. You can use sentence mining tools that extract vocabulary from media you consume, but these require technical setup and often produce inconsistent results.
This technical barrier creates a paradox. The learners who benefit most from Anki are often beginners who lack the language knowledge to create good cards and the technical skills to automate the process. Advanced learners can build sophisticated decks efficiently, but they already know enough language that they do not need Anki as desperately. The sweet spot of learners who would gain the most from spaced repetition faces the highest friction in getting started.
I remember a specific afternoon when this frustration peaked. I had just finished watching a Spanish film and wanted to add some useful phrases to my deck. The film contained a great expression I wanted to remember, something about how life unfolds unexpectedly. I paused the video, rewound the scene, and tried to type out the Spanish sentence. My keyboard did not have the accent marks, so I had to look up how to enable them on my operating system. Once I got the text right, I needed audio. I tried to record myself saying the phrase, but my pronunciation felt wrong. I searched online for native speaker audio and found nothing matching that exact sentence.
After thirty minutes of wrestling with technology, I had created one card. My brain was exhausted from the technical problem-solving, and I had lost the emotional connection to the phrase that made me want to learn it in the first place. The joy of discovering interesting language had been replaced by spreadsheet-style data entry.
This experience repeated itself enough times that I started questioning whether the system was worth the overhead. The spaced repetition algorithm itself was excellent. The problem was everything surrounding it. The card creation, the audio sourcing, the deck organization, the settings optimization. All of these tasks competed with actual language learning for my limited attention and energy.
Many learners solve this problem by abandoning Anki entirely and switching to gamified apps. These apps remove all the friction by providing pre-made content and polished interfaces. The trade-off is that you lose control over what you learn and how you learn it. You cannot add your own material easily. You cannot adjust the spacing algorithm to match your memory patterns. You are stuck with whatever content the app developers decided was appropriate for your level.
Other learners push through the Anki friction and become power users. They develop efficient card creation workflows. They build libraries of templates and automation scripts. They participate in online communities sharing deck-building strategies. These learners get tremendous value from Anki, but reaching this level of proficiency requires months of experimentation and frustration. Most people quit before they get there.
The real need is for a system that combines Anki’s algorithmic sophistication with the ease of use of gamified apps. You want the benefits of spaced repetition without spending hours configuring settings or building decks from scratch. You want to learn from contextual sentences rather than isolated vocabulary, but you do not want to hunt down audio clips for every phrase. You want content that adapts to your level automatically, introducing slightly harder material as you improve without requiring manual deck curation.
Finding this balance matters because language learning already demands significant cognitive effort. Every minute spent fighting with software is a minute not spent engaging with the language itself. The best learning tools disappear into the background, allowing you to focus on the actual content rather than the container holding it.
I think about this whenever I encounter a new word or phrase that strikes me as useful. The impulse to capture it is natural. The friction involved in actually storing it for later review determines whether I will follow through. If adding that word requires three minutes of setup, I might skip it. If it takes five seconds, I will save everything interesting I encounter. The difference between these two scenarios determines whether I build a rich vocabulary from real-world exposure or stick to pre-packaged textbook examples.
The learners who succeed long-term are not necessarily the ones with the most powerful tools. They are the ones whose tools create the least resistance to regular practice. Anki is powerful, but power alone does not sustain habit formation. Ease of use matters just as much, especially during those inevitable periods when motivation runs low and discipline carries the weight.
This is not an argument against spaced repetition. The science behind it is solid, and the results speak for themselves. It is an argument against the unnecessary complexity that surrounds many spaced repetition implementations. The algorithm should work for you, not the other way around. Your energy belongs to learning the language, not managing the software.
