Works like it should


Great developer support. App works good on the iPad, which is missing a stock calculator.

We've rolled out a fix to this problem. Should be able to work now. If you encounter any other issues, please reach out and we'll help you resolve it.

Great for longer operations, simple enough for everyday


The default iOS calculator is practical but the lack of history makes it less useful. I use it a lot when calculating my weekly budget. There probably better apps for that but this works great and I don't need any more complexity.

It could use a bit more features like being able to export calculations to notes and email. If it had that I would have given it 5 stars.

Simple but good


I love this app it's awesome. I like the fact you can delete your history with just a swipe at a time. Wish the (c)button would delete all but it only deletes one number at a time.
