Plan changes happen through Apple, not inside the Gust app.
Switch monthly ↔ yearly
Open the Settings app on iPhone.
Tap your name → Subscriptions → Gust.
Tap See All Plans (or Change Plan).
Choose monthly or yearly.
Apple prorates the change automatically:
Monthly to yearly: Apple credits the unused portion of your current month and starts the yearly plan today.
Yearly to monthly: the change takes effect when your current yearly period ends.
Upgrade to lifetime
The lifetime plan is a one-time purchase, separate from the subscription. To switch:
Cancel your current monthly or yearly subscription (see "How do I cancel my Gust subscription?").
Open Gust and tap Upgrade to Lifetime on the paywall.
Lifetime gives you Gust forever with a single payment — no renewals.
Keep one Apple ID throughout
Always use the same Apple ID for plan changes. Switching Apple IDs creates a separate purchase and won't merge with your existing access.
Still need help?
If you don't see the option to change plans, or you're stuck between two plans, tap Profile → Settings → Contact Support.
