Gauth: AI Study Companion

You'll need to register a Singapore Apple ID and purchase a Singapore App Store gift card to top up your account. Once the balance is added, search for Gauth in the App Store and subscribe. No Singapore bank card is required — gift cards are the most convenient payment method. Before switching accounts, make sure your current subscription is cancelled to avoid being charged twice.

The main risks include: App Store policy changes that may restrict cross-region accounts; purchasing gift cards from unofficial sources, which can lead to account issues; and auto-renewal failures if your account balance is insufficient, which will interrupt your service. It is strongly recommended to buy gift cards from official channels and ensure your balance is topped up before each renewal cycle to minimize account risk.
