Solid but slow
Response from developer
We have a brand new, completely redesigned and rewritten from scratch, app coming out in the next few weeks. It’s been undergoing beta testing by hundreds of Morpheus users for the last couple of months. Happy to add you to that so you can use it right now if you reach out to support@trainwithmorpheus.com.
It’s just ok when it works
Slow to connect
Response from developer
Our brand new app is ready for Morpheus User beta testing. If you want to join as a beta tester please reach out to support@trainwithmorpheus.com and we’ll add you and communicate how to get the app. We think you’ll find the difference between the old app and the new app to be night and day.

Heart rate zones

Too much effort to maintain
For all that effort, the main benefit that I got was some advice about modulating my heart rate ranges for recovery, and some suggested weekly targets for each zone. I thought the customized ranges were pretty cool! I used them daily and tried to follow the weekly targets as closely as I could… until about 3 months ago.
Yesterday I completed my first marathon. Training was quite challenging, and came with quite concrete goals—Morpheus targets meant little when I knew I needed to put down an 18 mile run for the day. So I took my readings but did the work I needed to in order to get ready for my race, not what Morpheus suggested.
But ignoring its suggestions for a few months has left me feeling like this app just completely miscalculates what a fitness app should be. So much time waiting for it to load, seeing it crash and having to restart, manually recording every run using a finicky process that only pays attention to heart rate even though that data and more is in Apple Health, and they just can’t be bothered to poll the API and use the data… meh. In the last 18 months, I’ve put many hours of effort into this app, and the value I got from it just isn’t remotely there. I think HRV is really interesting, and I hope to see it used more meaningfully by players in the health space with a stronger product focus. For now, I’m going back to Athlytic. I wish it had this recovery-based HR zone scaling, and a better way to score HRV, but it’s quite useful without it, and is just much more feature rich, providing greater analytic transparency and range, and taking advantage of the wealth of data available through Health integration.
Maybe I’ll check in with these guys if they ever release the app re-write they planned.
Needs a separate device purchase
Unreliable app

Not So Sure
If you use this app for z2 training, hedge on the low side.
New update glitching
Running iOS 18.3.2
Works well
IOS App needs work
There is potential but needs work
There is potential but data flow needs to be optimised.
Not ability to download my own data?
Much more than five stars.
And extraordinary support...
Yesterday, I'd used it for the first time. Leg day with a serious cold - feeling awful. Frustrated that I couldn't find the summary in the app. Wrote to support in a regrettable tone - not nasty but I was an absolute jerk. Support responded helpfully. I replied admitting my horrible tone asking them to forgive me, and they were so understanding. They spoke to me on a human level after the awful way I spoke to them. Feeling grateful for the product and the team.

Awful
Great!
App needs some work
1. Sleep time for checkin doesn’t always work right. Sometimes is pulls in the right time from my health kit data other times it is off by hours. Then I change it when recording the morning checkin and it then reverts to the wrong data when recorded.
2. Sync workouts sometimes hangs and you have to close the app and try again.
3. No way to correct information when syncing.the app pauses and asks if you want to import or skip after you recorded the data for the session - why not give you the opportunity to edit one last time.
4. The app should not default to a workout type when syncing. This is incredibly annoying because the little icons are easily missed. Leave it empty and force me to click on a work out type so it is correct.
Generally the app has a dated feel. Sad that you have a good product but a not so great app.
Came back to lower my rating - the default filling in of the workout type is insanely frustrating. LEAVE IT BLANK SO WE HAVE TO CHOOSE A WORKOUT TYPE.
Another day and I have come back to reduce the stars again. Please let me change the training data after it gets submitted. Apple health now tracks training load - they figured out a way to go back and edit data - why can’t you figure this out????
