Frequently asked questions

Is StarterLog really free?
Yes. Logging feedings, the rise timer, feeding reminders, and the hydration and levain calculator are free forever for one starter. A single $3.99 purchase — not a subscription — unlocks unlimited starters, the bake planner, the photo log and the widget.
Do I need an account?
No. There is no sign-up, no login, and no account anywhere in the app.
Does StarterLog use AI to tell me if my starter is healthy?
No. StarterLog has no AI photo scan. It reads your starter's health from the feeding log and rise times you already keep, not from a photo classifier that says the same thing every time.
How does the bake planner work?
Enter when you want the bread ready, and it counts back through feed, rise, mix, bulk ferment and bake to show exactly when to start — based on your own starter's recent rise times, not a generic timetable.
Is my data private?
Yes. No account, no analytics, no ads and no tracking. Your starters, feedings and photos stay on your device.
