User reviews

I want to love this, but it’s unusable.

I made a bit on an impulse decision in buying this calculator - it seemed to be an excellent upgrade from the aging desmos scientific app & the just horrible apple calculator. The features of this app are great, but the interface is scaled terribly. It reacts extremely poorly to being resized, and is completely unusable when not in full screen. 95% of my workflow with a calculator is either in slide over or split screen / windowed mode with another app, and when I try this with TechniCalc, the working space gets squished to the top while the keypad becomes enormous. I also thought the custom keypad layout would solve this, but it just replaces blank spaces with a weird series of dots in the tile. The side bar is massive, the keypad is massive, but the actual calculations themselves are squished against the top of the window. If you’re using matrices, they literally overlap on themselves. If this gets fixed down the line I could love this app and give it another try, but this is so terrible I can’t imagine it has been tested properly on iPad.

If you reach out to me in email with some screenshots of the issues you’re having, I’d love to try and address them. You can use the ‘contact developer’ link in the bottom section of the sidebar, or the menu on iOS

Simply amazing, but could use multi lines of history on the top

Quite a good and versatile calculator. The title describes my biggest gripe. One QOL improvement could be a bit of color coding for grouped buttons.

Thank you! 🤩 I don’t quite follow what your feature suggestion is. Reach out to me via email if you wanted to discuss further - my email is in the app
