Disclosure: I'm the developer. I didn't want to build yet another to-do app. What I wanted was something simple that I couldn't find: a reminders app that doesn't hide my own data or KI features behind a subscription or an account with questionable privacy but with a clean an easy design. So I made Tasklo: Reminders. What it is
It works on top of Apple Reminders. Whatever accounts you already have there (iCloud, Exchange, Outlook, CalDAV) show up in Tasklo, each list on its own.
No account, no sign-up, no servers of mine. Your data stays on your device and in your own Reminders accounts. Sync between iPhone and Mac is simply the sync you already have.
Tasklo is a fast, clean interface for your Apple Reminders on iPhone and Mac. Type a natural sentence and it detects date, time and list on-device. Includes a weekly view with drag & drop, subtasks, repeats, widgets, Siri & Shortcuts and a morning summary. No account, no server, no ads, no tracking: your data stays with Apple. One-time €2.99, no subscription.
