About
SinceBook is a calm, interval-first event tracker for iPhone and iPad. Log the things you want to remember when they happened — a doctor visit, an oil change, a call home, the last time you replaced the water filter — and SinceBook tells you how long it's been.
No streaks. No gamification. No dopamine loops. It's a logbook for the questions you forget to ask.
CORE FEATURES
• Log an event with a tap; add a note or backdate if you need to
• Adaptive interval display — "23 minutes," "2 weeks, 3 days," "3 years, 10 months" — or a rounded style like "almost 4 years"
• Timeline view with a distribution histogram and calendar heatmap
• Free-form tags to group and filter your list
• Pin your most important events so they float to the top and claim widget slots first
ALERTS
Every event can have multiple alerts — "every 3 months," "every 6 weeks," recurring or one-shot. Alerts fire as local notifications with a Log Now action right on the notification.
WIDGETS
Small, medium, large, plus Lock Screen widgets. Long-press any placed widget and choose Edit Widget to pin a specific event. The Small home widget includes an interactive Log Now button.
SIRI & SHORTCUTS
"Hey Siri, how long since I last called mom." "Hey Siri, log oil change in SinceBook." Three intents on day one: Log Occurrence, Check Last, Add Note to Latest.
MIGRATE FROM HINDSIGHT
If you're moving from Hindsight, import your CSV directly. Each Hindsight category becomes a tag; a preview screen lets you review and adjust before anything is written.
BACKUP, RESTORE, AND ICLOUD
Export your whole history to a JSON file whenever you want, restore anywhere. Optional iCloud sync uses your private CloudKit database — your data never touches our servers.
PRIVATE BY DESIGN
No analytics, no telemetry, no third-party SDKs. Everything stays on your device and, only if you turn sync on, in your own iCloud.
TIP JAR
SinceBook is free forever. If it's helping you remember the things that matter, three optional tips in Settings → Tip Jar let you say thanks. Tips don't unlock anything — every feature is already yours.

What's New in SinceBook
1.0.3
October 3, 2026
A quiet maintenance release. • Backup & Restore → Restore from JSON is now atomic. A partial or malformed file no longer leaves your library in an intermediate state, and errors surface with a clear message instead of failing silently. • Fixed the restore file picker; it could get hidden behind another sheet and appear to do nothing. • Fixed the Help screen's Email Support and Visit Website links — they were still pointing at the retired mentalhygienist.llc domain. Everything now points at mentalhygienist.app. Support: sincebook@mentalhygienist.app
