First of all - thank you for your great product.
Gave it a try and then realized that it is much easier to use compared to Training Peaks (at least Runalyze clearly states "rest days/ easy TRIMP" - really cool), although planning feature is missing.
But what kills runalyze (in my eyes) is lack of integration with online platforms - I got used that as soon as I push "save" on my Garmin, the activity goes to Strava, Endomondo and Training Peaks. And I may get Kudos in Strava and analyze my performance in Peaks with no extra effort.
(I use runalyze online).
As far as I know, Polar/ Suunto have similar integrations (that are must-haves nowerdays).
My view is that integration is really essencial. I realize that you have integration on your list (tapirik). I realize (saw somewhere on Garmin site) that they ask for money for API license (5K EUR as far as I remember).
I realize that I probably demand too much from free-to-use platform.
But I do beleive that integration is much-much more important then mobile app (that is on your list for "someday") - at least I can view runalyze website on my mobile (pretty usable), but ingegration requies actions after each activity.
I definitely willing to pay for it - so if you start crowdfunding I will be in the first line to back.
It changes everything in availability and user experiense.
PS: Yes, I am interested in Garmin first of all, but I think other devices will be also welcome.
