Free manual backtesting app for android

Greetings everyone, I have made a free manual backtesting app on android. It’s a very simple application for practising trading. I hope you find it enjoyable and useful.

Thanks for sharing your app with us! Any chance it will be available on Apple Store too?

Oh, that is so cool! what will they think of next!

Is this not hard on a small screen or it doesn’t matter with backtesting?
