Comments on ReactionFlash for Android

★★★★★ Abhishek Biswas · Aug 4, 2024

I consider myself a failed chemist since I learned nothing, but I still haven't given up on my dream of doing a Ph.D. in Organic Chemistry. Right now, I am preparing for my Ph.D. exam in India. Thanks to this application, it helps me quickly look up reactions and practice through the examples provided by the app.

★★★★★ ace luffy · May 4, 2025

Wow!! I've been in the chemical R&D industry for years and never seen such advanced app very well done!

★★★★★ Mehmud Alam · Jun 19, 2025

One of most important app for chemistry students. Very Helpful app. Mostly all important reaction are included with proper mechanism.

★★★★★ Nivin Vinod · Sep 8, 2020

Best app for referring Organic reaction. Could consider adding more theory and mechanisms

★☆☆☆☆ Ndeze Heritier · Jun 1, 2025

Please can you put reactions in the names of reactants?

★★☆☆☆ Catherine Salvini · Sep 23, 2020

This app has nice features, however as mentioned in other reviews the orientation is unstable rendering it unusable. It swaps between landscape and portrait mode and when turned to accommodate the new screen orientation it interferes with what the app is doing e.g. In quiz mode it switches to landscape if you rotate phone it pauses the quiz and returns to portrait orientation. It is severe enough that I cannot use the app, this can't be corrected by disabling landscape reactions in the settings.

O my god too too too much irritating ap 😠😵 Landscape view problem .........
