If you need to quickly find out the area of a room, roof, ceiling, or any shape in just a few clicks on the screen, this application is for you. If your shape has right angles, the program will correct them automatically. If the angles are not right, go to settings and apply angle correction, then from the very beginning of construction, you can create any shape. Move the angles to the desired location by long-pressing, merge walls by switching to the displacement mode at the bottom of the screen. If you have suggestions for improving the application, write to us, we will definitely listen to your opinion. (There is information in the settings on where to write.) We really hope that our application will make your life a little easier! Good luck!

Verdict
The clearest difference is in-app purchases: Calculator area at none against Notivation's 3. Calculator area also leads on device support (4 vs 2) and iOS requirement (14.0 vs 16.0). Notivation's advantage is ads (none vs shown) and update cadence (every 4 months vs every 11 months). On price there is nothing between them.
