Not very efficient, every time you fill in AB or C it covers the screen with the input keyboard. Most of the time when I use this app at work I'm trying to visualize what I'm calculating. So it's pretty annoying to tap out of the input just to look at the triangle every 30 seconds. And the ads make this app unuseable. I would just pay if it was optimized.

very helpful I would buy it if I could but I am not paying a subscription for a simple math app that has better competition without adds for free on iPhone

Hi, thanks for your review, we're glad you find the app useful. The app offers subscriptions for the equivalent of less than £0.07 per day which unlocks all of the calculation steps, formulas, and is ad-free. But it offers the core calculator functionality completely free. Thanks.

The ads are malicious and spammed constantly. Does the trig fine but really annoying to use.

Hi, this free app is supported by ads. Once you have watched a short ad you get unlimited, uninterrupted calculations for a set period of time. If you would prefer, you can subscribe to Premium for a completely ad-free version with additional features. Thanks.
