It won't be possible to sync a subscription activated on Remini Web on the Remini mobile app.
While our website shares some features with Remini's mobile app, the two services remain substantially different. If you started your subscription on Remini Web, your payment can't be transferred to or accessed on Remini's mobile app.
However, you can cancel any subscription that you've started on Remini Web and start a new plan on the Remini app that you can later use on desktop too.
