Kanbann brings Trello to your Apple Watch. Use it whether or not you have your phone nearby (it can work independently of your watch over Wifi or cellular). Using the app on your watch you can: * Create cards and archive cards * Move cards within and between lists * Append to a card's description * Comment on a card * Create checklists on a card * Create new items on a checklist * Uncheck and check items on a checklist. Updating and creating notes and lists requires a small in-app purchase, with a one week free trial. Create Trello cards using Siri on your watch: "Hey Siri, Create a task Testing 321 in Kanbann". In order to use this you'll need to do two things: Firstly enable Siri support for Kanbann on your *phone*, by saying "Hey Siri, Create a task Testing 321 in Kanbann" and tapping "Yes" (this is a one-time thing). Secondly on your *watch* you need to designate the default list for new cards by swiping down on the main page, going to Settings, and choosing the default board and list. Am I missing something?

Verdict
The clearest difference is update cadence: Bullet at weekly against Kanbann's monthly. Bullet also leads on rating (4.7 vs 4.4) and ratings volume (320 vs 12). 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. Kanbann sells 5 in-app purchases, starting at $1.99 per year and Bullet sells 9 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Bullet holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Bullet has 320 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 80% of Kanbann's written reviews are positive against 86% of Bullet's.
Kanbann ships an update monthly, Bullet weekly. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
