Rangewell Support

Check that notifications for Rangewell are allowed in Settings, and that the specific reminder is turned on and scheduled inside the app for the correct day.

Open the dosing schedule and check the amount entered for each day of the week separately, in quarters of a tablet or in milligrams, since a schedule set for the wrong day will not trigger the right reminder.

Export again after confirming the reading was saved in the app, since the CSV file is generated from the readings and doses currently logged on your device.

Use the restore purchases option in the app’s settings while signed in to the same Apple Account used for the original purchase.

Data only syncs across devices if iCloud sync is turned on, which is part of Rangewell Pro, and both devices need to be signed in to the same iCloud account.

Go to Settings, then Display, and match the number of decimal places to the way your laboratory reports INR, one, two or three places.

The latest version is 1.1, released on August 25, 2026. To update, open the App Store, tap your profile picture, pull down to refresh, then tap Update next to Rangewell. You can also turn on automatic updates in Settings › App Store.

Subscriptions are managed by Apple. Open Settings, tap your name, then Subscriptions, and choose Rangewell to change or cancel your plan. Cancel at least 24 hours before renewal to avoid the next charge; deleting the app does not cancel it. Refund requests go through reportaproblem.apple.com and are decided by Apple.

Check the following:

• all your devices are signed in to the same Apple Account;
• iCloud is turned on for Rangewell in Settings › [your name] › iCloud, and in the app’s own settings if it has a sync switch;
• your iCloud storage is not full;
• each device is online: open Rangewell on both and give it a minute.

Sync runs in the background, so Low Power Mode or a weak connection can delay it.

In Rangewell, use the option to delete your data in the app’s settings, where available. Deleting the app removes the data stored on that device. To remove the copy kept in iCloud, go to Settings › [your name] › iCloud › Manage Account Storage, select Rangewell and delete its data.
