Your scores deserve more than a forgotten photo of the screen. Bowly tracks every frame, every spare leave, every pin, then shows you exactly where to improve. Whether you're chasing your first 200 game or grinding through league night, this is the companion app that actually makes you a better bowler. TRACK YOUR WAY - Pin-by-pin input: tap the pins left standing, confirm, done. Under 5 seconds per frame. - Quick score mode: just punch in the numbers if you're in a rush. - Live Sync: connect to your lane at supported ComputerScore centres and scores update automatically. No typing. No distractions. COACHING THAT WATCHES YOUR GAME Real-time tips adapt to what's actually happening on the lanes. Left the 10 pin three times? Bowly notices before you do, and tells you what to adjust. Fatigue creeping in during Game 3? You'll know. On a streak? It'll tell you to stay in rhythm and change nothing. STATS THAT ACTUALLY HELP - Average trend over time: see the trajectory, not just tonight's number - Pin leave heatmap: a visual map of exactly which pins you leave most often - Spare conversion by leave type: find out if it's the 10 pin or the 3-6-10 that's costing you - Game-by-game breakdown: spot fatigue patterns across Game 1, 2, and 3 - Strike percentage, clean games, 200+ count, season milestones SESSION RECAPS YOU'LL ACTUALLY READ After every session: your three game scores, series total vs. season average, first ball breakdown, spare conversion rates, and a plain-English insight like "Your 10-pin conversion cost you 12 pins tonight." BUILT FOR THE ALLEY Dark theme. Big buttons. Works offline. Bowling alleys have terrible WiFi and dim lighting: Bowly is designed for exactly that. Haptic feedback on every pin tap, strike, and spare makes scoring feel satisfying, not like data entry. LIVE SYNC WITH COMPUTERSCORE At supported centres, connect to your lane and Bowly pulls your scores live as you bowl. No manual input needed. Just bowl, glance at your phone between frames, and get coached in real time. Currently available at 60+ centres across QLD, NSW, VIC, SA, WA, and TAS. Free to use. Your data stays on your device. No account required.
