Congrats on this launch! I love that there is no data tracking and collection outside of the device (it’s always a plus point). However, after downloading the app, I don’t understand the following in the Setup menu screens. Please look at these from a newbie perspective. 1. Time Period — not sure what this refers to. Why is the maximum only 30 days or one month? I think some text to explain that screen would help. 2.…

Hey thanks for the feedback. Very useful.

Congratulations! I also wrote an iOS app to do this exact same thing, although it’s unfinished and unpublished. I had a lot of trouble getting the app to perform well (what’s your secret?!) Couple of things I implemented that you may want to consider: 1) onboarding flow to help users setup the app on first launch 2) filter certain workouts to include/exclude by type, duration, etc 3) home screen widget Id love to cha…

Hey thanks for the feedback. The secret? I'm not sure? You had issues with the speed or getting the data and updating the view? What I did is adding a loading indicator and fetching data onChange, so if I change e.g. bow heart rates are calculated it starts to fetch instantly after the change not only on the view with the bars. And I'm currently just fetching 30 days. I think this will be interesting if I try to exte…

My speed issue was in getting the data (although I think it is fixed now).

The other big performance problem I've had is the simulator hanging when I try to use Swift Charts.

My primary interest was in monitoring my total zone 2 time for cardio workouts where I spend at least 30 consecutive minutes in zone 2. However I've reduced the scope for now while I get the minimum viable app up and running.

I would prefer an adaptive approach where the user also enters perceived difficulty and the app learns the correlation between heart rate and perceived difficulty to figure out the zones. I consistently have high heart rate during exercise: a normal walk might get my heart rate to 130, and a moderate run (10:30/mile) might get my heart rate to 180. A very fast run gets my heart rate to 215 (this is beyond the max mea…

If your Garmin HRM can write data to the Apple Health app then it would use that HR data. Without measuring your lactate threshold, you don't really know what your zones are. Apple has a concept of "effort" which is a single rating for the entire workout and it'd be interesting to incorporate that.

Sure, again, all granted. To reiterate the thesis of my prior comment, 'Fair to ask, but show the courtesy due an equal at least until it is evident that is unwarranted.'

Where is the lack of showing courtesy? I asked a question in response to them asking me to download and use their app. Have we reached a point in this world where simply asking a question is offensive? They had every right to choose not to respond just like I can choose not to use their app if they don’t. How you respond is your choice, if you chose to take offence to a question about the long term sustainability of…

A cultural difference, perhaps. I read your tone and line of questioning as brusque if not just shy of insulting, but if you are familiar with the 'ask vs. guess' distinction, I hail from an exceptionally "guess"-oriented culture which I, ironically belatedly, gather may be uncommon in this discussion. Pray excuse me.

Yes I like that concept of effort. My question basically boils down to whether the user-provided effort value should be used to calibrate the zones.

Thanks for this. As the developer of the app, I must confess that to get to the current state was mainly motivated by having fun coding and a general willingness to release it. There was no plan, in that sense, where I want to be in a year or so. For now, I want to focus on building a great product, and the confirmation of a great product for me would be to see usage. To me, to maintain the app for now seems to be not a lot of effort.

No need to be excused, you did nothing wrong, we misunderstood each other is all.
