Refunds on iOS are handled directly by Apple. Here is an instruction on how to request a refund from Apple. Please note that Apple does not allow developers to issue refunds themselves, so Fits cannot provide support for refunds.
On Android you have 2 ways to request a refund. Either via Google directly or contacting Fits support to issue the refund for you.
Contact Google
Contact Fits
Alternatively you can reach out to us directly with this form.
Please include your Fits username or email address used so we can process your request. We will then refund your payment via Google Play.
