Appreciate for this logical app ## Most critical reviews (10 lowest-rated) ### 1/5 — Asking subscription for such basic thing??? *2026-01-17, version 1.12.0* Asking subscription for such basic thing??? ### 3/5 — purchase but didn’t unlock *2023-09-25* please fix! **Developer response:** Hi! Thank you for bringing this to our attention. We apologize for the inconvenience you faced. We've released a new update that addresses the purchase unlock issue. Please update the app and let us know if you continue to experience any problems. We appreciate your patience and support. ### 4/5 — Please make a way for users to mark items complete *2025-02-14* Nice study tool. Would be better if we could mark sections understood as we move through sections to make it easier to navigate. **Developer response:** Thanks for suggesting the topic completion feature. I will add it in future updates. ### 4/5 — Half of content behind paywall *2021-05-20* Extremely limited in content unless you pay. I would rather have a version of the app fully paid instead of a “free”-mium model. Despite that, beautiful rendering of DFS for graphs. ### 5/5 — Add More Programming Languages *2026-06-30, version 1.18.0* The app is an excellent tool for understanding how data structures and algorithms work visually. The UI is clean, and the animations make learning so much easier. It’s one of the best visualizers I’ve used so far. However, it would be great if you could add more core programming languages to make it even more comprehensive. Some suggestions include: • Kotlin • Dart • Javascript • Swift Adding these would make the app an even more powerful learning companion for students and developers preparing for interviews or improving DSA fundamentals. Keep up the great work! Excited to see new updates and more algorithm visualizations in the future. ### 5/5 — Code language *2026-01-05, version 1.12.0* Bro please provide C++ language for the code given been waiting for long time for the update. ### 5/5 — Muy buena. Y la tradujeron al Español! *2025-12-12, version 1.12.0* Excelente! Sigan agregando ejemplos en Python ### 5/5 — Una joya de app *2025-12-11, version 1.12.0* Actualizo mi reseña, ahora con la nueva actualización se añadieron otros idiomas. Totalmente recomendada para aprender sobre estructuras de datos y algoritmos. Gracias al desarrollador por la actualización 😁 ### 5/5 — Good but a bit pricey tbh *2025-04-22* I like the effort and visualizations but i think the price is a bit much for something easily found online. Its interactive which is great but $5 id pay for it, not $10 **Developer response:** Thank you for your review and five stars! I understand your concern about the price of the app. I would like to point out that this is a one-time fee and the content with updates will be yours forever. The content is indeed easy to find online. It's just a matter of how it's organized. I think this app is very well-designed and has great pedagogical value. Believe me, you are unlikely to regret purchasing this application - a number of things here are unique and you will no longer have difficulties with knowledge in this area, since the visualization remains in memory for a long time. Thanks again for your feedback and opinion on the price. By the way, the price started at two dollars. As content was added, the price went up a little. Money is hard to come by for many people and I don't want to say that $10 is not that much. Everything is relative. ### 5/5 — Best iOS app for DSA! *2024-08-09* This is a great app to watch and learn algorithms in detailed simulation along with its pseudo code! Amazing app, but it’d be great if the storage space could’ve been optimised. 200-300mb app is kinda big for a 16gb iPhone here 😔 **Developer response:** Thanks for the great review and for noting the app’s size. I’m aware it’s a bit large, and I’ll consider this for future updates. Also, look out for a new release with fresh content this month! Your feedback is invaluable - thanks again. ## Most praised reviews (4 highest-rated) ### 5/5 — Do you have this in python? *2024-07-03* Python? **Developer response:** Thank you for the 5-star review! Yes, the app includes Python implementations for data structures and algorithms. Just head to the ‘Code’ section in each topic’s menu, and you can toggle between Java and Python to see the code in your preferred language. ### 5/5 — Highly Recommended *2024-05-02* I highly recommend this application to those seeking to either newly learn or reinforce their understanding of fundamental data structures. Designer(s) show deep understanding of data structures through the illustrations and their backing program codes. They provide quality updates and improvements to the application as well which I have seen over the time. Top notch and inspiring, keep up the good work! **Developer response:** Thank you so much for the glowing review and recommendation! It's great to know that the updates and improvements are making a positive impact. Your support and kind words inspire me to keep enhancing the app. Thanks again for your encouragement! ### 5/5 — User interface *2023-03-01* It is clean and the tutorials are great ### 5/5 — Simple, clear, educational *2021-04-09* This is perfect. Clear definitions and explanations with even clearer and cleaner visualizations. No extra mess, just clear information. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
