So informative and handy

ReactionFlash is a very informative application. It is a very handy source of name reactions. I have been entertaining myself doing the quizzes during the nights with a beer in hand.

Please fix the landscape swiping

You can’t swipe through reactions in landscape mode without them shifting partially off screen and requiring an app reset to fix the issue. If this were fixed, the app would be super intuitive and helpful! Hope it gets fixed!

Science accessible as it should be

App is easy to use and understand, well developed and it is FREE. Its a nifty little study guide in my phone, and it saves me a ton of time in the lab. I like that it includes the mechanisms, examples and quizzes too. Very helpful, thank you for making this! A suggestion: Hinsberg test for amines 👍🏼
