Your schedules,
actually on your calendar.
Schedules are everywhere. Your calendar is the one place they’re not. Sieve reads them, keeps watch on the ones you follow — and nothing already on your calendar moves without your OK.
How it works
Add a source
Share a PDF, paste a URL, snap a photo — Sieve handles the rest.
Review events
Sieve shows what it found. You decide what gets added.
Stay in sync
With each update, Sieve verifies and shows you what changed.
Why Sieve
Private by default
Everything is parsed on your device. Your documents and calendar data never leave your phone.
You stay in control
Set your rules once. Sieve handles the routine updates and flags anything unusual before changing your calendar.
Tracks changes
When a source updates, Sieve shows exactly what changed — what moved, what’s new, what’s gone.
Works with what you have
School calendars, lunch menus, sports leagues — if it lists dates, Sieve can turn it into events.
