I’ve used the QS Access app over the years and still do. I’m happy it still works, however there have been numerous additions in Apple Health data that QS hasn’t stayed up to date with. I’m able to get that data through an Export from Apple Health, but the speed and round trip isn’t comparable to QS.
Over the years I’ve seen a few posts inquiring about open source. Has there been any recent consideration been given to opening up the code base for further development? I’d love to help work on things and take them further.
