I suppose you could just use insert link and all it’d require is an exclamation point edited in at the front, but a dedicated button would be nice for those that didn’t know that was the formatting. I didn’t know myself until this thread.
I’m glad I did though, now it’ll be easier to add images to my comments!
Sports but not specifically walking, I use FitNotes. I mostly use it to track my weightlifting progress but it does have the ability to track time so I do track my cardio on the same app.
It has Google Drive backups too which is nice
