Good but a bit pricey tbh

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

Response from developer

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.

Nice study tool. Would be better if we could mark sections understood as we move through sections to make it easier to navigate.

Thanks for suggesting the topic completion feature. I will add it in future updates.

Best iOS app for DSA!

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 😔

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.

Do you have this in python?

Python?

Response from developer

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.

Highly Recommended

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!
