Built a golf coaching app in 8 weeks during heart surgery recovery — would love feedback

After 30 years in IT and selling my tech firm, I finally had time to come back to golf. A routine annual exam caught a heart issue I didn't know I had — and during 8 weeks of recovery in Arizona, I built My Golf Insights.

The frustration: every golf app I tried (18Birdies, Hole19, Arccos) tells you what you shot. None tells you what to actually fix.

What MGI does differently:

• After every round, ranks where you LOST strokes by impact
• Tap any stat → see exactly which holes contributed • One specific drill for your biggest leak
• Tracks stuff most apps miss (3-putt distance, scrambling, chip outcomes)
• 100% offline. No app store. No accounts. PWA.

Tech: vanilla JS PWA (no framework), IndexedDB + LocalStorage dual persistence, Cloudflare Pages, Lemon Squeezy for payments.

Launching this month at $14.99/yr founders pricing (first 200, then $29.99).

If you golf — would love feedback: mygolfinsights.com

If you're building solo — happy to share what I learned shipping a PWA in 8 weeks. AMA.
