### 5/5 — Useful equations app

*2024-03-09*

Update - The scrolling issue has been fixed. Thank you for this excellent app!

This app is a helpful reference for basic equations. Not finding any description of what the “advanced equations” in-app purchase included, I purchased it but don’t notice anything different in the app. Well, I would have spent .99 on the basic app anyway because it’s very helpful. The information in the “description” section are explained well, but on my iPhone 12 mini it won’t scroll at all so it only shows the top portion.

**Developer response:** Howdy! Thank you for the kind review and purchase. I'm happy to read that the app has been helpful for you! 

My yardstick for "advanced equations" were those that I couldn't do the math in my head even on a good day. For instance, Voltage equals the square root of current times resistance, and then the db gain equations as well. Only a few of them are locked because I believe in usability over all else. 

Thank you for reporting the issue with the description sections. I will be sure to include a fix for that in the next release.

I hope you continue to find the app useful and please don't hesitate to contact me with any issues in the future!
