MENGENAI EPISOD INI
Solo Dev Journey #2 is here because you asked for it. This one is about the single question every developer, my own programmers, and even Andre keep asking: “You spend $4.5K a day and make $4K a day… and you’re happy? That makes no sense.” It makes perfect sense, and I open my Singular account on camera to prove it.
I walk through the CPI vs LTV equation the way a UA person actually uses it: the time element (D7, D30, D90, D365 LTV, never D0), why the payback period is set by where your retention curve dies, and why Robot Breaker sitting at $250K spent and $170K back is not a problem, just a cohort that hasn’t finished paying. Then I switch to One Mage Army, launched September 6–7 on Android only, and show the real numbers: 60–80% day-1 ROAS, 120–200% ROAS days, 103% ROAS for the whole month on $40K, and scaling from $200 to $1K/day in a week to $2.5K/day now. The game is maybe 30% feature-ready. Mark my words.
Plus: the channel mix (AppLovin started terribly and is now one of the best; Unity Ads surprisingly good; Google and Mintegral added), how organics move with paid spend, the cheaters sideloading APKs and faking IAPs from Germany and Vietnam, the license-key fix in Singular, and the dashboard I built with Singular’s MCP and a “UA senior Matej” skill so I can make daily decisions without spending eternity in spreadsheets.

03:45 – “You spend $4.5K and make $4K?” – the CPI vs LTV equation explained
05:20 – Robot Breaker: $250K spent, $170K back, 30-day payback and why that’s fine
06:45 – One Mage Army month 1: 60–80% D1 ROAS, 103% on $40K, scaling 5x

📌 KEY TAKEAWAYS
— LTV has a time element; your payback window is where your retention curve flattens
— Spending more than you make today can still be profitable; cohorts pay back over 30+ days
— Every channel, geo and creative has its own LTV curve; tailor UA to each
— Verify purchases in the store console; cheaters will fake IAPs once you get popular
