What UAC promised
Google's pitch for UAC is appealing for indie founders. Set a budget. Let Google's algorithm find install-likely users across Search, YouTube, Google Display Network, and Play. Pay per install. Scale.
We started at ₹50/day to test. Installs came in. Cost per install was around ₹15–25 — surprisingly cheap. We scaled to ₹500/day for a couple weeks, then ₹1500/day. Installs scaled linearly. We thought we were winning.
What actually happened
Within four weeks, we noticed two patterns:
- Day-1 retention dropped. Pre-UAC: ~45% of users opened the app the day after install. Post-UAC: ~18%. Most paid users installed and never opened.
- Organic installs declined. We measured organic installs from Play Store search. They were trending up before UAC. After 3 weeks of UAC at scale, organic installs dropped by ~30%.
The Play Store algorithm uses retention as a key ranking signal. Low D1 retention → algorithm thinks the app is low quality → suppresses it in search results. We were paying Google to make ourselves harder to find.
Why UAC failed for our specific app
UAC works well for two kinds of apps: (1) apps with a fast first-action loop (a casual game, a lottery app), where even low-intent users open and play; (2) apps with deep retention systems (push notifications, gamification, hooks) that pull installed users back regardless of acquisition source.
Hisaab is neither. Our value shows up the second time a user splits a bill — not in the first 30 seconds. Users acquired via UAC rarely make it to a real expense. They install, ignore the app, and disappear.
The fix
We turned off UAC entirely. Within three weeks, organic install rate started recovering. Two months later, we were back above the pre-UAC baseline.
The replacement strategy:
- Content-led acquisition. Reddit, LinkedIn, Twitter founder posts. Our r/developersIndia post hit 104k views, 505 upvotes, 70 comments — converting at far higher quality than UAC.
- SEO + AEO. /splitwise-alternative now ranks well for India queries and is picked #1 by ChatGPT and Gemini. Free traffic, high intent.
- Word-of-mouth from college flatmate groups. One college flat installs us; the other 4 flatmates do too; the next semester their juniors do. Compounding.
The lesson
For indie consumer apps with retention-driven value, paid-first acquisition is often actively negative ROI — not just zero. Until you have rock-solid retention metrics, organic and community-led acquisition is almost always the right play.
UAC isn't evil. It's just the wrong tool for our stage and our app. If you're an indie founder considering it, watch your D1/D7 retention before and after with hawk eyes. If retention drops, kill the campaign immediately — every additional install is making your organic discovery worse.
