All your recurring work, at a glance for the whole month. The things that come back every week or every month are the first to slip. You jot them down somewhere, forget them, and rebuild them from scratch the next time. You download yet another app to get organized, and a month later you've already abandoned it. Caledo is built around one idea: the work that repeats should already be there, ready, without you redoing it every time. Open the app and the whole month is in front of you — one single scrolling space, no folders, no menus to dig through. Your recurring activities become cards with a life of their own: set the rhythm once — daily, weekly, monthly, quarterly — and every deadline is already waiting in its place. Complete today's, and the next one arrives with its countdown updated. See at a glance what's done and what's left. With Caledo you can: - See your whole month at a glance — recurrences ready, deadline after deadline - Capture anything instantly — by voice with Siri, from Shortcuts, or with a tap — into your global tray, without even opening the app - Always know what comes next: deadlines and priorities up front - Turn repeating work into ready-made procedures, with files and images attached to each step - Organize clients and projects into workspaces and cards - Sync with Apple Reminders - Stay in sync across all your Apple devices with iCloud Your data never leaves your iPhone. Caledo collects nothing. Nothing at all. Caledo comes from a simple belief: almost every productivity app is built for teams, and you carry their weight for an audience that isn't there. Caledo starts with you, with how you actually work. Privacy Policy: https://www.caledo.app/privacy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Extreme Agenda's advantage is ratings volume (79 vs 1) and chart position (#82 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
