ReDo Loop is a minimalist tracker for tasks you don’t want in your calendar — life maintenance like changing sheets, replacing filters, watering plants, trimming nails, paying bills, and scheduling checkups. Relaxed repeats Most apps repeat on fixed dates. With Relaxed, ReDo repeats after you complete a task — so “every 3 months” means 3 months after you last did it. A calm list that stays clear Tasks move through Upcoming (early), Do (today), and Overdue (late), so you always know what needs attention next. Repeat tasks your way • Relaxed — after you complete the task • Fixed — specific dates or weekdays • Positional — first Monday, last weekend day, last day, etc. • Daily — everyday routines • Tracker — simple tracking with optional notes • Once — one-time reminders (dated or someday) No accounts. No ads. No analytics. Works offline with local data. Free to use with limited functionality. Upgrade to Premium to unlock all features.

Verdict
The clearest difference is update cadence: ReDo Loop at every 8 days against ZenZettel's every 2 months. ReDo Loop also leads on ratings volume (15 vs 1). ZenZettel's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ReDo Loop sells 3 in-app purchases, starting at $0.99 per month and ZenZettel sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
ZenZettel holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ReDo Loop has 15 ratings behind it against 1, so its average is the more settled of the two.
ReDo Loop ships an update every 8 days, ZenZettel every 2 months. The most recent releases landed on October 9, 2026 and October 12, 2026 respectively.
