Price
The paid plan “GRIT Pro” is an auto-renewing subscription that can be purchased only through App Store billing inside the iOS app. There is a monthly plan (product ID: com.grit.mobile.pro.monthly) and a yearly plan (product ID: com.grit.mobile.pro.yearly).
Each plan includes a one-month free trial the first time. The free trial can be used only once in the same subscription group, including monthly and yearly. If you do not cancel before the free trial ends, the plan you chose renews automatically.
The price is shown in the app and on the App Store purchase screen as the regional price returned by the store. This website does not list a fixed amount.
Purchases from Android and the web are not offered. With the same GRIT account, a GRIT Pro entitlement bought on iOS is reflected in the plan check on other devices.
Tax display follows the App Store purchase screen.
Charges other than the product price
You pay any data charges required for your internet connection.
Payment method
Payment is made through Apple’s App Store (the payment method on the Apple ID). Google Play billing is not offered.
When payment is due
When payment is taken follows the App Store. If you do not cancel during the free trial, the chosen plan is charged when the trial ends, and then automatically on each renewal date.
When the product is delivered
You can use the app as soon as the download finishes. GRIT Pro becomes available after the App Store purchase completes and the app confirms the subscription.
System requirements
The paid plan can be purchased only in the iOS app from the App Store. Supported devices follow the App Store listing.
Returns, cancellation, and termination
Cancel before the next renewal from “Manage subscription” in the iOS app, which opens App Store subscription management, or from Apple’s subscription management. After you cancel, you can keep using GRIT Pro until the end of the period already charged. Refunds follow Apple’s policy. We do not take payment or issue refunds ourselves.
Because this is digital content, we do not accept returns ourselves. Whether a refund is available, and how to request it, follows Apple’s App Store policy.
