MMR Tracker
Manual per-match MMR tracking, for non-Dota Plus subscribers — and for Dota Plus subscribers too, since it only shows your MMR delta once a day, not right after each game. Type in your MMR after a match and this works out the +/- delta for you automatically, using whatever you typed for the match before it. Also shows your account's current rank and estimated MMR, plus your last 20 matches, fetched fresh whenever you click Refresh.
FAQ
Why track this manually instead of trusting Dota Plus? Dota Plus only shows a single MMR delta once a day, batched across every match you played that day - it won't tell you which specific game cost or earned you points. This logs the delta match by match, tied to the actual game, so you can see the swing from one game at a time.
Where does the match history come from, and is it stored anywhere? OpenDota, fetched fresh every time you click Refresh. Everything you type in here - saved profiles, per-match MMR entries, rank history - is kept in your browser's local storage, not on a server, so it's tied to this device and this browser.
