Review summary

Users broadly praise the app for clear, understandable explanations and helpful visuals that make learning algorithms easy and affordable. However, recurring issues include problems with purchases and restoring access on new devices, broken feedback features, limited content with a call for more algorithms and regular updates, a demand for a dark mode, and translation/localization gaps.

Pros

Easy to understand explanations of algorithms
Useful and valuable for learning; good price/value
Clear graphics and visuals that aid understanding
Good for learning basics and getting started with algorithms
Strong value for premium/purchased algorithms

Cons

Purchase/restore issues: purchased algorithms not showing as purchased on some devices
Feedback mechanism is broken (Send Feedback)
Content is limited; need more algorithms and regular updates
Lack of dark mode; request for dark mode is common
Translation quality issues and localization gaps

2026-05-29	Yu*****	the free version of this app touches so few subjects in such an elementary manner that you're better off accessing free resources online for each subject. Definitely an appreciable effort of an app, but this app has no actual audience

2025-10-24	Sa*****	very very useful app. fully trust japanese to bring the best in tech. very easily understandable about all main algo in math used in tech today. very well priced. the graphics are easy to understand. need more such useful trustworthy apps from Japanese tech skills.

2025-08-23	Dz*****	In Merge Sort, last step when all the numbers get merged into a single top group - it is not clear how last merge comparing is done. I.e. left group has 3,4... and the right one 1,2... So, if follow the explanation we should get into 3,1,2,4 for the last merge. I think last step needs more details. I hope your project is still live for you :-) and you have enough energy and time to fix this. Take care and good luck! P.s. "Send Feedback" is seems to be broken...
