Tools for training and sport tracking — the short answers
Every number here comes from our own daily check — not from a vendor list.
Tools for training and sport tracking — how many are there?
Tablif is tracking 660 of them. 642 answered our check today, and 11 we couldn't reach — we don't claim those are dead.
Which ones are still maintained?
Tablif knocks on every door once a day and records the answer. 642 of these 660 responded on the latest run, so that number is what "still here" means on this page — not a review score.
Are any of them free?
108 of the live ones say so in their own words, and 47 let you start without making an account. Tablif records the claim the product makes; we don't verify pricing.
Any open-source options?
36 of the live ones on Tablif mention being open source.
What's the newest one?
DanceOnMusic — Tablif first saw it today.
Did a person actually look at these?
655 of them Tablif opened and read, then wrote a one-line summary in our own words instead of reusing the founder's tagline. The rest carry keyword labels we haven't confirmed by reading yet — and we say so rather than hiding it.
