Love this - it’s simple, looks clean, with no ads. There is one little bug; a leading . (point) is ignored. So if you type in 5x.4 for instance it turns into 5x4. Easy to work around, instead type in 5x0.4. But it should be fixed.
This app is really a gem! Obviously it does what we want it to do! Add, subtract, multiply and divide. Still glad I learned math from Mrs Brommel back in, the mid sixties, she was tough. But now, quick, arithmetic without the developer knowing what color underwear I use. By-the-way, SuperMan underroo’s to be exact. Thank you Cheolchan Um!
This is the one I love. Get to see all the bills I paid until I remove for next month bills. If I get a notice that I have not paid one I can look back at my calculations and see if I missed it. Great job. Wish all apps were as simple and easy to use as this app.
