Avoid

Donโ€™t be an idiot like me and spend money on a calculator you can easily find elsewhere or just ask AI. This doesnโ€™t even work well and they canโ€™t get wording right. Shocking really.

Love the save function and visuals

Been loving this app and appreciate not needing to pay a subscription like all the other ones for the same thing.

Good little app. Just does its job.

Can't use .

Useless for my needs. Can only use whole numbers. Need to be able to use 12.67 etc. Please advise, thank you.
