Customer Reviews

Great app!

Love this app from top to bottom. I was also impressed by the customer service given to me a few weeks ago. I had contacted them about an issue that came about with the new iOS. They said they were working on a fix. A week passed and I received a follow-up email letting me know that my issue was fixed in their new update. Only thing I would add is having more options when it comes to customization of the calculator, having additional skins would be nice. Highly recommend this app to anyone who is looking for a well made, professional calculator.

Keep up the good work guys!

No pop-up in Pro Version

If you upgrade from the free version, you must delete the old icon and open in new icon. The upgrade does not occur in the same icon. So if you are still seeing pop ups you are still using the free version.

Serious Input delay

Every time I start the app, return to the calculator from another app, or even return from a menu within this same app, the first Key I press on the calculator takes about a second to register visually and by sound. It’s pretty annoying. Would be 5 stars otherwise.
