About a year ago, a software developer going by JEulerius started building small mobile apps after his regular work hours. Nothing flashy… things like sobriety trackers, supplement trackers, anxiety trackers. The kind of apps you search for when you need them, download quietly, and use every day. By the time he hit 14 apps live on both iOS and Android, he’d found something that actually worked. Last month, revenue crossed $1,000 for the first time.

Getting there wasn’t a straight line.

The pricing mistake that held him back

For the first several months, he was earning about $10 a day; not nothing, but not the traction he was hoping for. The problem, he now realizes, was the business model. He was selling features as one-time purchases at around $5 each. Low commitment from buyers, but also low ceiling for him.

A month ago he switched everything to subscriptions. Revenue jumped almost immediately. His top app, Sober Tracker, now drives more than 50% of his total income on its own. His newest release, Supplement Tracker, started generating revenue within two weeks of launch. The recurring model didn’t just change the numbers, it changed the whole feel of the business.

(Worth noting: his monthly recurring revenue is still growing, currently sitting around $153/month, while the bulk of his $1K revenue comes from annual and lifetime plan purchases. He’s reinvesting everything back into ads.)

What actually moved the needle

He’s run enough experiments now to have a clear picture of what works. Three things stand out.

Name your app what people search for. His most successful app is called “Sober Tracker.” Not “SobVersy.” Not something memorable or brandable. Just the plain, obvious thing someone types into the App Store when they want that exact thing. Boring names rank. Creative names don’t.

Screenshots and descriptions carry more weight than most developers expect. The app store listing is the sales page. Treat it like one.

Subscriptions beat one-time purchases, full stop. He wishes someone had told him this from day one. The revenue floor is higher, the trajectory is better, and buyers who subscribe are more committed to actually using the product.

On the marketing side, he’s kept it lean. App Store Optimization has been his primary driver, and he’s now experimenting with Google Ads and Apple Ads. Reddit Ads didn’t work well for his category, too expensive, poor conversion, but he’s open to organic community approaches down the road.

The bigger lesson

JEulerius isn’t trying to build the next billion-dollar app. He’s building small, useful tools for people going through specific things; quitting drinking, managing supplements, handling anxiety, and he’s packaging them in a way that makes the business sustainable. Fourteen apps, each earning a little, adds up faster than one big swing that might never land.

The switch from one-time to subscription pricing was the unlock. Everything else from the ASO, the straightforward app names, the niche focus, was already working. He just needed the revenue model to match.

Pick a problem people already search for. Name your app exactly what they type. Then charge them monthly.
