About

Vellum Schedule

Features
Read full description

Vellum is a calendar that works the way you think: as a note. Type naturally and watch structure appear. "13" becomes Monday, July 13. "1 doctor" becomes 1 PM - doctor. Add "3 coffee" and events order themselves chronologically with clean separators โ€” you never format anything. WRITE, DON'T FILL FORMS - Dates from plain typing: 7/14, tomorrow, next friday, halloween - Times that understand context: "3" knows whether you mean AM or PM - Multi-day events in one line: "7/14-16: Molly's" fills every day - Untimed notes pin to the front of the day, alphabetized ALWAYS ONE STEP AHEAD - Press return and tomorrow's date appears faintly, ready to accept - Type any date and see a live preview before you commit - One backspace undoes any automatic change โ€” you stay in control YOURS, EVERYWHERE - Sign in with just your phone number โ€” no password, no email - Your schedule syncs to your account and survives any reinstall - Works offline; changes sync when you're back - Delete your account (and all data) any time, in-app No ads. No tracking. Just a page that organizes itself while you write.

Verdict

The call

The clearest difference is in-app purchases: Vellum Schedule at none against PDF's 1. On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. PDF sells 1 one-off in-app purchase. Vellum Schedule asks for nothing beyond the download.
