About this app

What Hyzerlog does

Hyzerlog is the disc golfer's personal logbook — your rounds, your bag and your lost plastic, all in one quiet app with no subscription attached. Log a round hole by hole against par, tag the course and layout, and your history builds itself: rounds this month, best score per course, average against par over time. The bag is where Hyzerlog earns its spot on your home screen. Add every disc you own with its flight numbers — speed, glide, turn, fade — along with mold, plastic, weight and condition. A flight chart lays your whole bag out on one grid so the gap between your most understable fairway and your beat-in mid is obvious before you're standing on the tee wishing you'd brought something else. And because every disc golfer eventually donates plastic to a pond: the lost-disc log. When a disc goes missing, record the course, the hole and how it vanished. If a kind stranger calls the number you sharpied on the flight plate, flip it back to recovered. Over a season you'll know exactly which holes eat your discs and what that habit costs. Hyzerlog is 100% offline. No account, no sign-in, no cloud — everything is stored locally on your iPhone with SwiftData and never leaves your device. And it's free. • Hole-by-hole round scoring with par and totals • Course list with play counts, best scores and notes • Full disc bag inventory: flight numbers, plastic, weight, condition • Flight chart to visualize your bag and find the gaps • Lost-disc log with recovery tracking and replacement cost • Completely offline and private — no account, ever Download Hyzerlog and give your bag the logbook it deserves.

Features

Built to be useful, not noisy.

Round journal

Log a round hole by hole against par with course, layout and date; a home screen shows recent rounds, score-to-par trend and personal bests.

Disc bag inventory

Catalog every disc with mold, brand, plastic, weight, condition and the four flight numbers (speed, glide, turn, fade), with an in/out-of-bag toggle.

Flight chart

Plot the whole bag on a stability-versus-speed grid so gaps and redundant slots are visible at a glance, filterable by disc type.

Lost-disc log

Mark any disc lost with course, hole and circumstance (water, woods, never found), flip it to recovered if it returns, and see total discs and dollars lost per season.

Why it exists

The problem

Disc golfers have no single free tool that covers the three things they actually want to remember: how they scored on each course, exactly what's in their bag (with flight numbers, so they can fill gaps instead of buying duplicates), and which discs they've lost and where — UDisc paywalls stats behind a $30/yr subscri…

What's different

How Hyzerlog stands out

Unlike Fairway (this portfolio's ball golf round logger — different sport, different equipment model: disc golf is bag-centric with per-disc flight numbers, not club sets and GIR stats) and unlike Chainside (this portfolio's live disc golf scorecard for keeping a card during group play), Hyzerlog is a bag-first person…
