We’re here to help
Check the common questions below, or email us and we’ll get back to you.
Does FastStack require an account?
No. There is no FastStack login. Use the app with data stored on your devices, with optional sync through your own Apple iCloud.
How do I add supplements quickly?
Open Stack, add a supplement, and fill dose, form, and schedule. You can search product labels to help fill details. For a head start, use the tiny starter in onboarding or Settings → Load Demo Stack.
How do reminders work?
Allow notifications when prompted. Reminders can include Taken / Snooze / Skip actions on iPhone, iPad, and Mac. Adjust meal times and notification preferences in Settings.
How do I start a custom fast?
Open Fasting, pick a preset or create a custom technique, then set start and finish times (including later today or tomorrow). Optionally enable start/finish reminders. You can edit times on a scheduled or active fast.
My devices aren’t syncing
Sign into the same iCloud account on each device, keep a network connection when possible, and confirm iCloud is enabled for FastStack in Settings. Sync can take a moment after changes.
What about Apple Watch?
The Watch app covers Today checklist, fasting start/end, water, and stack glance. Install FastStack on iPhone so the Watch companion is available, then open the Watch app once after install.
How do I deactivate or delete a supplement?
In Stack, swipe or use the context menu to deactivate or delete. From the editor you can also delete with confirmation. Deactivate keeps history; delete removes the supplement and its dose history.
How do I export my data?
Open Settings and use the CSV export. The file is created on your device and you choose where to share it.
Where is my data stored?
On your devices, with optional sync through your own Apple iCloud (CloudKit). We don’t run FastStack accounts or our own database of your logs. See the Privacy Policy.
