Frequently Asked Questions
How do I subscribe to SupStack Pro?
Open the app, go to Settings, and tap "Upgrade to Pro". Choose between Weekly or Monthly subscription. Subscriptions are managed through your Apple ID and will auto-renew unless cancelled.
Can I use the app without a subscription?
Yes! SupStack is free to use with up to 2 supplements and 7 days of history. Upgrade to Pro for unlimited supplements and full features.
Where is my data stored?
All supplement and water tracking data is stored locally on your device. We don't sync to the cloud, so your health data stays completely private.
How do I set up reminders?
When adding a supplement, toggle "Notify me" on and select your preferred timing (Morning, Afternoon, Evening, Night, or Anytime). The app will request notification permission if needed. You can customize exact times with SupStack Pro.
What counts toward my daily streak?
You can choose in Settings → Streak Tracking whether your streak counts when you complete all supplements, reach your water goal, or both.
How do I restore my subscription?
In the app, go to Settings → Subscription section, then tap "Restore Purchases". This will restore your subscription if you've previously purchased it on this Apple ID.
What happens if my Pro subscription expires?
You'll keep all your data, but access will be limited to your first 2 supplements and last 7 days of history. Resubscribe anytime to regain full access.
How do I delete a supplement?
Tap the supplement on your home screen, then scroll down and tap "Delete Supplement". You'll be asked to confirm before deletion.
Can I track water in different units?
Yes! You can switch between ounces (oz) and milliliters (ml) using the toggle on the Water screen. Your goal and history will convert automatically.
