“DoBuff” is primarily built around Reminders and Calendar, providing core features such as time management, progress tracking, goal management, and more. “DoBuff” is designed to enhance Reminders and Calendar with a range of powerful additional features, helping you use them more effectively. “DoBuff” started as a collection of tools I built for my own use with Reminders and Calendar. It was developed around my personal needs and is now available for anyone with similar needs. If you are also a Reminders or Calendar user like me, “DoBuff” may be a great fit for you. Core features and goals (supported for both Reminders and Calendar events): 1. Display tasks and events on a timeline. 2. Unique weekly, monthly, and yearly planning views. 3. Two separate tag systems that can be used independently or synced with Reminders. 4. Focus timers based on Reminders for better time management. 5. Progress bars based on Reminders, with lists serving as progress trackers for goals. 6. Completion and time-spent statistics for Reminders lists. 7. Trend analytics, including tag-based focus time statistics, list tracking, yearly heatmaps, time paths, footprint maps, and more. 8. Countdown support for Reminders. 9. Mark Reminders as abandoned or postponed. 10. Calendar integration, including reading events and writing focus sessions to Calendar. 11. Counting and count tracking. 12. Enhancements available for Reminders are also supported for Calendar events. 13. Export and back up Reminders. 14. Reminder countdowns with support for system alarm countdowns. 15. Note templates for quickly adding notes. 16. Add notes to lists. 17. A range of widgets, including Focus widgets, Calendar widgets, Goal Tracking widgets, Today widgets, and more. 18.

Verdict
The clearest difference is update cadence: DoBuff at weekly against Hambook's every 6 weeks. DoBuff also leads on ratings volume (39 vs 3) and iOS requirement (17.0 vs 26.0). Hambook's advantage is rating (5.0 vs 4.8). On price, review sentiment, ads and in-app purchases 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. Hambook sells 3 one-off in-app purchases and DoBuff sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Hambook holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: DoBuff has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Hambook ships an update every 6 weeks, DoBuff weekly. The most recent releases landed on October 8, 2026 and October 6, 2026 respectively.
