User reviews

Love it!

Great support from the developer + open for new ideas and improvements. My #1 calculator.

Just what I needed

Very easy to use and understand. Even calculates water to use. REQUEST: A cycle calendar and dose log would be a wonderful edition. That way I could have this as my one stop pep app. Thanks!

With the price

I tried many of the “free” apps. They were super annoying trying to force me to subscribe. This app after a one time payment and does everything i want. Thanks!

Actual Customer Support

I thought I as charged twice but I wasn’t. I reached out via email and Someone Got Back to me!!

Update-bugs fixed. Was working great, but now there's bugs

Update- reached out to Support and they fixed the app in a matter of days.
All of a sudden, when I edited then saved the calculation to a saved protocol, it deleted all the notes that were there previously, which had not occurred in the past. It's also not letting me edit notes in saved protocols.

Response from developer

Hi Aimee, Sorry about this! Note loss is the worst kind of bug to ship and I'm sorry you got hit by it. The new "rich text" notes functionality added in the last release caused a couple issues. I tracked down what was happening and the fix is already pushed. The "can't edit notes" issue is also fixed. When opening the app it should update automatically. To ensure you have the new version check the bottom of the More tab for v55.5.2 Thanks for taking the time to flag this. I'm hopeful you'll also take the time to update your star rating if you see fit. Thanks! Jeremy
