FAQ
Frequently Asked Questions
Why 4,000 weeks? +
The average human lifespan is approximately 77 years, which equals roughly 4,000 weeks. This number is both abstract enough to feel distant and concrete enough to be meaningful. It's inspired by the book "Four Thousand Weeks" by Oliver Burkeman.
How do I create tags for different life periods? +
Go to the Tags tab and tap the '+' button. Give your tag a name (like "College", "Boston", or "Career Phase 1") and choose a color. Then you can apply it to weeks through the tag's calendar view or by selecting date ranges.
Can I add notes to individual weeks? +
Yes! Tap on any week in the grid to open its detail view, then add or edit notes. You can also view all your notes chronologically in the Journal tab.
How do I zoom in on the grid? +
Use standard pinch-to-zoom gestures on the life grid. You can zoom in to see individual weeks more clearly or zoom out to see your entire life at once. The current week is marked with a special indicator.
Is my data backed up? +
Your data stays local on your device for privacy. You can export your data to create your own backups. Future versions may include optional iCloud backup while maintaining privacy.
Can I change tag colors after creating them? +
Yes! Tap the "Edit" button on the Tags screen, then tap any tag to change its name or color. All weeks with that tag will automatically update to reflect the new color.
What happens to weeks I haven't lived yet? +
Future weeks are shown in a muted color in the grid. You can still tag them (for planned life phases) or add notes (for goals and aspirations), but they're visually distinct from weeks you've already lived.
How do I apply tags to a range of weeks? +
Press and hold a week from in the main Life Grid view. You can drag from the selected week to select a range of weeks. If you don't get the right range, you can click the button labelled "Range" in the multi-week select view to select the starting and end week using the standard date pickers.
Can I export my life grid? +
Yes! You can export your data including tags, notes, and week assignments from the Settings tab. This allows you to back up your data or move it to another device.
