### 5/5 — FINALLY!

*2024-07-11*

been using instacalc for years have always wanted an app version! it’s a great little tool perfect for quick calculation and conversion, has a lot of similar tools for spreadsheets and work but a bit more user friendly yet still be able to do a lot of the same stuff. it’s got a lot of neat features and is really good with factor/labeling. have used it for everything from calculating best ticket yield per chip for dave and busters games to how fast usain bolt’s world record 100M is in miles per hour. I never write reviews but when an app like this comes around and is completely free you remember that some people do things for the joy of it. kudos to the developer rock on brother!
