For people with ME/CFS. This app helps you to pace and stay within your energy envelope. Use your phone and watch to monitor your daily heart rate, steps and distance.

Integrated with HealthKit.

This app uses the Health app to monitor resting, average and maximum heart rates, heart rate variability, step count, walking distance and active energy.

Set your individual thresholds for nominal, caution, warning and critical levels. Keep an eye on your status on phone and watch. Add complications to your watch face to alert you when you cross thresholds.

Please note: currently at least one complication is required on the active watch face for background alerts. Alerts on the watch are not instantaneous - background checking occurs every few minutes during the day.

What’s New

Version 2.2

- Added extra large watch complication for overall status
- Heart rate variability complication shows in colour
- Fixed and improved extra large complication for active energy
- Improved compatibility with watchOS 9

This is very helpful to set warnings for heart rate or steps. It’s good for teaching where your limits are so you know to stop and rest. There is a place where you can set your own thresholds for the limits. The only thing I wish is that you can reset it for heart rate. I have Postural Orthostatic Tachycardia Syndrome along with the ME. My heart rate is very variable. I can hit the threshold and lay down and have my heart rate go back down. But later I will get up again and need the heart rate reset.

Developer Response ,

Hi. You can reset the alert for any of the parameters. On the watch a double tap will reset to "from now on". A repeat double tap will reset back to midnight. You can also long press to pause a parameter if you want to ignore it for the rest of the day. On the phone long press on a parameter to bring up a menu to access these same functions.

We hav needed this for so long

ME/CFS folx, I highly recommend. You can set and modify your own parameters. I wish it integrated with Oura ring, but I get around this by updating my Apple Health details from my Ours ring throughout the day. I am excited to see how this helps me better pace over time. THANK YOU so much for building this!!!

To both the developer and the one who wrote first review

Also a long hauler. I saw me/cfs and based off my symptoms with the POtS dysautomia and heart rate bp and activity energy wise this is me in a picture. I’m under tax so the a medical team and what testing do we need to send me to to help make sure this is the diagnosis and so we can figure out if the vaccine caused it. I am 36 former healthy athlete no medical bc except allergies to pollen and ragweed and took Claritin daily. I am RN and never had Covid to my knowledge if I did it was asymptotic. Got my booster 6 months ago and have been struggling with 100-149 hr up and down from lying to sitting and or any kind of activity weight loss but all muscle from what I guess was over exertion. I had chicken pox in kindergarten (91) mono in highschool (2003) htn and hr will both be up and once hits certain point get dizzy and have had syncope but now I know to lay down when the black tunnel is coming or see dots bc my ANS is going to kick in and bottom out my pressure. What testing labs and procedures & specialist do we need to go to? Any info will help and this app is a life saver. I will definitely pass it along for the others like us! ❤️❤️💪💪💪💪
