Is there anyway you can add a feature where it saves your recent calculations

by Bi*****, 2025-11-07

This app is amazing and saves so much time. Would be really cool if there was a memory feature to look up recent calculations while app is still open.

This app works great. As long as I enter all the numbers in correctly my film turns out. It even works well when I’m calculating for a concrete shot. It stopped working after a recent IOS update. Hoping it gets back up and running soon!
