I've been using this app for years. I don't particularly know why. 92% of the time, I am only using the bare absolute base calculator function. It's the other 8% that keeps it installed. It's really handy to convert weight, fluid measurement, and whatever else by clicking on the app you are already always using.

This has been a great app, but I can't clear the history anymore without going into phone settings and clearing the cache there. The clear history doesn't work anymore. I can clear individual items but not all at once. This is a recent problem.

Simple app that allows you to calculate almost anything that you may need. Giving 4 stars instead of 5 since most simple apps give the option to buy a lifetime subscription, given that most options can now be simply be googled, I'd be willing to pay the lifetime subscription to have everything in one app
