it's one thing for an author to have a good idea but this author's execution is on point.
I am a wastewater treatment operator and I utilize specific formulas every workday. Since finding this app, I’ve been using it exclusively for all my needs. If the developer sees this, may I ask for the functionality to add text descriptions?? Not sure how to implement it but that would be the icing on the cake. 5/5 recommend
Thank you for making this app, I don’t know how to use spreadsheets to automate math equations for me so this is a life saver fr. It’s so easy to use and very self explanatory!🤗🤗🤗
I love to do “what ifs” with numbers and this app makes it so easy to do so.
This is a perfect spot between a calculator and a spreadsheet. I started out tracking my relocation expenses. Now anytime I need to do a calculation, I quickly open up a new sheet and type it out. This app instantly automates my calculations and syncs to iCloud. A very unique calculator app. Please release an iPad version.
