What's New in CoPace

0.14.0

September 18, 2026

CoPace now lives on your Home Screen and Lock Screen. Add the new Reserve widget and you can see today's read and how much of your Reserve is left without opening the app. There is a small one, a large one, and Lock Screen versions. Press and hold your Home Screen or Lock Screen, tap the plus, and search for CoPace. If you forget the app exists, you can now ask for a short morning reminder to open it for today's read. It is off unless you turn it on, in Settings under Notifications. Getting a new phone? Settings now has Back Up or Restore. Save one file to iCloud Drive or Files, then restore it on the new phone and your history and settings come with you. If you change your mind, you can go back to what was on the phone for 7 days. The Home read is more honest about your day. Once you have used today's Reserve, the big headline stops inviting you to do more and says so. It only describes recent evenings when you actually logged them, and a small dip in your morning reading now reads "about your usual" instead of "above". History has a new chart of time over your threshold while you slept, night by night over 30 or 90 days. It never uses your daily budget. It is there because a few of you were watching that number on the Home screen and wanted to see how it moves over weeks. Garmin users: some Garmin watches don't share heart rate variability, and CoPace used to keep asking you to wear the watch to bed when that could never help. It now tells you plainly what your watch can and can't send, and everything that doesn't need HRV keeps working. Apple Watch users who weren't getting overnight readings now get told about sleep tracking, which is usually the reason. Also: switching your data source now restarts your baseline so readings from one device are never compared with another's, and the CoPace Score chart no longer sends you to Settings when your threshold is being held at your resting heart rate. Be gentle with yourself out there.

User reviews

Helpful and affordable

I’ve been looking everywhere for a pacing app that is affordable, doesn’t require additional hardware than what I already own, and doesn’t over-promise. I’m still in early days of having this app, but the information it gives has been incredibly helpful. I appreciate the gentle framing of the information and frequent reminders that you’re not doing anything wrong.
However, I do wish that the graphs provided more of a comparable breakdown of the numbers with more specificity. I’m hoping to see that in the future, as this app so far seems fairly comprehensive.

Response from developer

Thank you for this generous, thoughtful review. It means a lot to hear the gentle framing and reminders are coming through the way we intended. We're happy for your feedback on the graphs as well, more specific, comparable breakdowns is a great idea and we'll be building toward that.

Messes up my numbers

I’ve installed this app twice and both times it affects my steps and active calories numbers in Apple Health despite not allowing it access. It’s supposed to only read not write.

Response from developer

Thank you for the honest feedback, and we're sorry this soured the app for you twice over. CoPace doesn't have permission to write steps or Active Energy, so it cannot change to those numbers. But we don't want to just leave it there. If you email support@copace.app or submit feedback from within the app then we'd be glad to look into what you're seeing with you.
