Brilliant, with potential

First, this app is totally brilliant. Specific strengths include (a) the timer with calendar integration, (b) the differentiation between start/due dates, (c) repeat after completion vs. repeat regularly option, (d) stats (beautiful!), (e) affordability, and (f) the motivational home screen (which I dont really use, but I appreciate its value nonetheless).

Second, the 4 things that would make this app absolutely indispensable (in order of importance) would be:

Computer access/sync. Whether it was available as a menu bar app (preferably with the timer/stopwatch time in the menu bar), a web app, or desktop app, being able to use this app on the computer would be an amazing addition that would improve my workflow.
Syncing timers across devices. At present, the timer only runs on the device where you start running it. Though of course it syncs the completed time across devices, it would be amazingly helpful if you could start the clock on one device and turn it off on any other device.
Regular prompts when timer is running. It would be wonderfully helpful if there was some sort of regular reminder to remind you that a timer is running, whether just a reminder notification: “your timer has been running for 30 minutes,” or a prompt with options: “your timer has been running for 30 minutes. are you still working on [task]?” (e.g., Harvest) or a menu-bar icon (Mac) or Notification Center widget (iOS/Mac) that would show the running timer.
Not adding new events for recurring tasks (e.g., Nozbe). Sometimes the app gets cluttered if I haven’t done some of my recurring tasks in a while. Preferably, only one copy event would ever show at a given time.
