Hyzerlog
Your rounds, your bag and your lost plastic — the disc golf logbook in a browser tab
Score a round hole by hole against par, build a course library with play counts and best scores, catalogue every disc with its flight numbers, see the whole bag on a stability-versus-speed flight chart, and log the discs that go swimming. Free, no account.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in Hyzerlog on the web
Hole-by-hole round scoring
Set par and your score for 9, 18, 24 or 27 holes; the total and score-to-par update as you go, then the scorecard colours every birdie, par, bogey and double.
Course library
Every course keeps its city, hole count, notes, play count, best round against par and average — created automatically the first time you log a round there.
The full disc bag
Mold, brand, plastic, weight, condition, replacement price and the four flight numbers — speed, glide, turn and fade — grouped by putter, midrange, fairway and distance.
Flight chart with gap finder
Every disc plotted on stability (turn + fade) against speed, so the hole between your beat-in mid and your most understable fairway is obvious before you are on the tee.
Lost-disc log with recovery
Record the course, the hole and how it vanished — water, woods, tall grass, out of bounds or never found — then flip it back to recovered when a stranger calls the number.
Season cost of donated plastic
Open losses are totalled at replacement price, so you know what the pond on 16 has actually cost you this year.

Try it with sample data: Loads four New England courses, eight rounds over the last two months (including a career round and a donated Leopard3), a twelve-disc bag from putters to distance drivers, and three lost-disc reports — one still in the pond. You can start fresh at any time.

Questions
Is the web version of Hyzerlog free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Hyzerlog iPhone app?+
No GPS, course maps or hole distances — the iPhone app doesn't have them either; courses are your own list with your own notes. Discs are described by their flight numbers, not photographed; the iPhone app has no disc photos either. Everything is stored in this browser, so a different device or a cleared browser starts with an empty bag.
