Read full description

Mnemo is a minimal daily planner built around one idea: your tasks shouldn't disappear just because the day ended. NOTES Write your tasks for the day. Assign a time, link each one to a colour-coded page — Work, Study, Exercise, or whatever fits your life — and mark them done with a double-tap. No clutter. No complexity. MEMORY Anything you didn't finish gets remembered. It resurfaces as a chip the next time you open Mnemo, ready to be rescheduled to any page and any date in two taps. Nothing slips through the cracks. TIME Navigate by date. See your notes on a calendar. Set times for what matters. Mnemo keeps everything anchored to when it actually needs to happen. SIX COLOUR-CODED PAGES Organise your life across up to six named pages, each with its own colour. Work and personal tasks stay separate without any effort. BUILT TO STAY OUT OF THE WAY Minimal design. Light and dark mode. No accounts, no subscriptions, no noise. Double-tap a note to edit, link, or mark it done. Double-tap a memory chip to reschedule it. Mnemo — notes, memory, time. https://cherrypow.github.io/cherrypow-apps/#privacy https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
