iOS Energy Drink Collection Game with Caffeine Tracking

An iOS app that turns every energy drink you scan into a collectible while tracking your caffeine intake. Scan the barcode, the app identifies the drink, logs the caffeine, and drops it into your collection with a rarity tier based on how few other players own it. Points, ranks, streaks, leaderboards, friends, DMs, clans with chat, tier lists, widgets, and Apple Health–informed stats like half-life and bedtime cutoff.

Launched June 2026, built solo. 3,361 installs, 2,825 collectors, 40,526 drinks scanned, 2,271 signed-in users in the last 30 days. 84% of installs scan at least one drink. Collector retention is 68–79% at week 1 and 37–45% at week 4, flat across every cohort.

Paid subscriptions went live 2026-08-21 and are at $97 MRR three weeks later, with 24 subscribers, zero refunds, 44% trial-to-paid, on six Apple-approved IAPs. Roughly breakeven today on ~$88/mo hosting; a written fix in the next build halves that.

The sale includes the TikTok account that drove the installs: 1,408 followers, 139.8K likes, four videos over 100K views, all organic. Installs ran 400 a week when I was posting. The funnel, not the product, is what needs an owner.
