Not usable, the constant ads make the app freeze, crash, and become completely unresponsive. Introducing a subscription for a basic calculator with such limited functionality comes across as pure greed. A small one‑time payment would be reasonable, but a recurring fee for something this simple is absolutely unacceptable. For anyone looking for an alternative, 'Mobi Calculator' is a far better option. The app is free and earns revenue without annoying users with an overpriced subscription model.

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.

ClevCalc is a highly-rated, all-in-one calculator app that goes far beyond basic math. It's praised for its clean interface, history feature (letting you see and edit past equations), backspace key, and powerful scientific functions. Users love it for everything from simple finances and tipping to unit conversion and loan planning, calling it "far superior to the default calculator" for everyday task i mean wowww!!!😋✨
