Best calculator by far

Love this calculator. It’s so good. Only wish is to add a setting to bring back the old keyboard layout. I cannot get over my muscle memory from old versions.

Best calculator I’ve ever used, and I’ve used a lot of them

I’m an accountant, so a good calculator is absolutely critical. Soulver is so much better than any other calculator I’ve used before. I’m not sure there is anything it can’t calculate, and I only use a fraction of its features. I also really like that it keeps a history of everything I’ve done to refer to later, and screenshot or print for documentation.

Worth every single penny!!

First off I wasn’t paid off in any way to leave this review I just truly love the work the developer has done with this app. Thank you for not giving into the AI and making a subscription out of it.
