Say for example I can add my grocery bill up and see the total right on my screen. That was until a recent update. Now the widget shows nothing. That kind of breaks the app for me. -- russell_314, 2026-03-25 ### ***** "Perfect calculator" It got all your bases covered!! Even for conversions ! Easy to use! Great tutorial when you first open the app! …. Get it now u won’t regret it! -- Carlos Rivero, 2024-02-29 ### ***** "Fantastic, full-featured, and free" Really love this calculator. It does everything I want, especially the option to do per unit price calculations easily. If I could add one option to the wishlist of updates it would be a cleaner icon or even better choice of icons to select from. -- bsewall, 2024-02-14 ### ***** "SO GOOD AND FREE" I hate calculator apps that paywall certain features and shove it down your throat about paying a subscription. THIS APP IS TRULY FREE AND I LOVE IT. Please add an option to donate/tip inside the app, would love to have the OPTION to support the development. -- shayshoegrr, 2023-09-19 ### ***** "Great free app" What is this!? A free calculator app that works great, has a widget setup and no adds or monthly fees for a simple calculator app… I’ll take it! Strongly recommend. -- Bigdrj, 2023-03-25 ### ***** "Honestly, great." There isn’t much to say this calculator is bad with. It works wonders with stage manager on iPads, which is enough to make this my daily use calculator. Even over an old one I paid for! Only hitch is I can’t seem to get support for an issue I have. I get an 404 error for the developer contact page. -- FairytaleForest, 2023-03-09 ### ***** "It Really Is FREE!" This is a good calculator with basic and scientific functions. It has some nice features such as the built-in overlays. There are no advertisements! It really is completely free. -- Geo_, 2023-01-23 [View all Calcsmos reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Calcsmos Discovered Keywords -
