The calendar you'll
actually want to open.
20+ themes, a Home Screen widget, and lock-screen wallpaper — with instant sync to the calendars already on your iPhone. No account needed.
Dress your calendar
20+ themes — from clean minimal to Y2K neon, 8-bit pixel, terminal green, and cozy animal worlds. One tap restyles the grid, event bars, fonts, and your widget.
Widget & lock screen
A Home Screen widget keeps this month in view, and a matching lock-screen wallpaper shows your monthly note too — without opening the app.
Sync without an account
Apple, iCloud, Google, Outlook — any calendar connected to your iPhone shows up automatically. No new account, no migration, nothing to set up.
Month, week & day
See the whole month or zoom into hour-by-hour detail. Fonts, event-bar styles, accent color, and week start day — all adjustable.
Notes & checklists
Jot a one-line intention for the month or build a tickable to-do list, and save the events you add often as quick templates.
Private by design
No account, no sign-up. Your events stay on your device and in your iOS calendars, and there's no ad tracking.
Opaline is free with the default theme. Extra themes are one-time purchases — individually, in theme packs, or unlock everything with All Access. No subscriptions, ever.
