Mediquations, the first medical calculator for the iPhone, has been retired.

I've made the difficult decision to discontinue Mediquations to focus on future projects.
Thank you for your support over the last 12 years!

If you've purchased Mediquations in the past, you can still reinstall your purchase for the near future via the App Store through the 'purchased' section.

If you purchased the iOS app after December 15, 2020 and would like a refund, please contact Apple to see if you are eligible for a refund. Keep in mind only Apple can process refunds.

If you purchased the Android app after December 15, 2020 and would like a refund, please request a refund through Google.
