Must Do is not a to-do list. It is a private system for the rituals that define your standard. Create the recurring things that must keep happening in your life, then mark them done in seconds. Train. Read. Study. Post. Stretch. Take creatine. Hit your macros. Whatever your non-negotiables are, Must Do gives them a quiet, elevated home. Built for speed Must Do is designed to feel immediate. Open the app, tap the ritual, and move on. No clutter, no noisy dashboards, no endless task management. Just a fast, clear record of what must happen. Designed for standards Every ritual has its own identity with a title, icon, and color. Set daily, weekly, or monthly recurring rules, organize your rituals the way you want, and keep your system clean as your life evolves. See your consistency The home screen keeps your current rituals front and center, while the calendar view gives you a calm history of what you actually completed over time. Filter by one ritual or many and see the pattern without getting buried in analytics. Smart reminders Add reminders to the rituals that matter most. Must Do can remind you at the right time, and it will stay quiet when you have already completed the ritual for the current day or period. Private and local-first Your data stays on your device. Must Do is built to feel personal, focused, and owned by you. Must Do is for the people who do not want another productivity app. It is for the standards you keep. 1456 characters If you want, I can also write: a more luxury / Apple-style version a more conversion-focused App Store version a shorter punchier version Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is ads: Must Do's at none against Week Calendar's shown. Must Do's also leads on update cadence (every 4 days vs fortnightly). Week Calendar's advantage is device support (5 vs 2) and iOS requirement (15.6 vs 18.0). On price and in-app purchases there is nothing between them.
