Most habit trackers are a phone app with a Mac version bolted on, or a Mac app with none, and nearly all of them want a monthly payment for the privilege of counting your own days. Cadence is one native app on both, and habits are one of its four core modules: always in the sidebar, Command 4 away on the Mac, and in the tab bar on the iPhone.
The part that matters is how it counts. Start a habit in March and the completion rate begins in March, rather than dividing your fortnight by a whole year and reporting seven percent for something you have never missed. Every habit shows its current streak, its best, and its rate, with a grid of days behind it that keeps the bad fortnight visible in June.
There is no account to make, because there is no server to keep one on. The app is free on one device, and iCloud sync across your Mac and iPhone is $14.99, paid once, with no subscription behind it.
