HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (348 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Terrible

Terrible. Really not worth the money. Make your own deck. The cards can pile up to 146 words in a day even when you’re set to learn 5 new words a day, because it never gives you a chance to review words using spaced repetition. If you don’t know the word and you press again or hard it pops up as the next card over and over again, so you’re forced to review again the next day by pressing the green button. I have no idea why you can’t alter how often you can review a card and the developers won’t address these simply issues that make learning vocab hard. They just ignore you. I wasted so much money on this for a yearly subscription and I regret it so much. I will never recommend this app to anyone.

★★★★★Jul 14, 2026
Better vocab than duo lingo

26 provides much needed visual/audio flash cards and a good system to balance learning vocab effectively. I especially like the anime themed Japanese lessons because the art is very visually effective in promoting and relating learning though visual and audio cues.

★★★★★Jul 13, 2026
언어 공부는 무조건 26초로 시작

자식 낳아서 언어 공부 시키려고 해도 이것부터 사줄 듯요. 듀오링고처럼 컴퓨터 앱과 연동기능이 없다는 게 좀 아쉬워요.

★★★★★Jun 20, 2026
Probably the best app so far

This app so far is helping me and I have adhd bad and it’s keeping my attention 100% better than any of the other apps that I’ve paid so much for and for the most part your not having to pay for this one or at least I haven’t had to yet mad respect to whoever made this app I never knew this could be so fun in the same way playing my pc games “cod” like I said 10/10 app going to be trying to learn as much as possible so I can travel the world when I get old and enjoy the best life ever ps I don’t care about my comment not having punctuation

Dumb

I was excited ti try this app but it seemed to require a signup to use it and unfortunately didn’t have a way to give an email. Only Google or Apple. Dumb!

No wasted reviews on words you already know. Every session focuses on what matters most, so retention stays high with minimal effort. This is how memory actually works. This is how 26s beats every other flashcard app. KNOW WHAT YOU KNOW Real tests. Real level. Honest results. Measure your true progress with rigorous quizzes built to mirror actual exam conditions. No more guessing where you stand before test day. NEVER MISS A DAY Building a daily habit shouldn't depend on motivation. Live Activities put your progress on your Lock Screen.
