He Flipped 4 Apps and Made $500K — But He Didn't Sell to the Highest Bidder

Hey, it's Jennie.

I came across a really interesting story today. A developer named Lotts, originally from London, has been building and selling apps since 2022. He's done it four times now, and his total revenue crossed $500,000.

But here's the thing — his background is pretty unusual. He came from banking, left, raised VC funding, and spent three and a half years grinding on a startup. You know how everyone thinks they're going to be the next Zuckerberg? He thought that too. Three and a half years in, it failed.

But then something unexpected happened.

While licking his wounds, he thought "let me just build a random app." And it happened to be 2022 — right when GPT was going mainstream. He rode that wave and built his first app, Bible Buddy. All the existing Bible GPT apps were doing Q&A — you ask a question, it gives an answer. He flipped it. He turned it into an AI therapist that empathizes emotionally, then asks you questions after the conversation.

The 7-Step "Build & Flip" Playbook

This was the meatiest part of the video. A step-by-step strategy refined through selling four apps. Let me break each one down.

Step 1. Spot Trends in the App Store

Look at the #1 app in each App Store category, then check if there are multiple similar apps in the Top 20 of that same category. Use Sensor Tower to verify their actual revenue. If multiple apps are pulling $100K+ MRR in the same niche, that's a signal that something real is happening there.

Step 2. Find Your Differentiation

Once you spot a trend, carve out your own niche within it. Lotts chose the Christian market for two reasons: he's Christian himself so he understands the audience deeply, and tech tends to reach religious markets last. His strategy was to fill that gap before others caught on.

Step 3. Build It Single-Player

This was the most practical advice. A lot of people try to add social features — the kind where "you need to invite friends to get value." Lotts says absolutely not. Build an app that delivers full value to a single user, alone. Social can come later. If you need to market to two types of users from day one, it gets way too complicated.

Step 4. Nail Either Shareability OR Retention

Here's a fascinating insight: "Nobody shares the app itself." But people do share what they create inside the app. Magic Music was exactly this — you'd make a diss track about your friend and send it over. The friend would think "I need to make one too" and download the app. You shared the song, not the app, but the app spread anyway.

Pray Screen went the retention route instead, and the results were wild — Day 30 retention hit 60%. That's virtually unheard of in the industry. The secret? The app locks your other apps. You have to pray to unlock your phone. You literally can't avoid using it every single day.

Step 5. Keep the Tech Stack Simple

When you're selling, buyers who can't understand the tech will walk away from the deal. So you need to build plug-and-play from day one. Stick with React Native across the board. Keep operations as simple as possible.

Step 6. Grow with UGC

This is the marketing core. Before running paid ads, create multiple UGC accounts and post rage bait content. The kind that makes people rewatch or argue in the comments. TikTok's algorithm sees the high engagement and pushes it out.

Once you find hooks that work, convert them into Meta ad creatives. For Pray Screen in the US market, CPI (cost per install) was just 30-50 cents — an absurdly low number.

Step 7. Sell It

This was the most surprising part. Get the app to $10K-20K MRR with the last three months trending upward, then sell. But here's the twist — don't sell to the highest bidder.

Go to the 3rd highest bidder and say "there are two people above you, but if you can close in 3-4 days, I'll sell to you." The buyer thinks "lucky me" and wires the money immediately. Chasing the highest price drags things out, and the longer it takes, the more likely the deal falls apart.

Valuation sits around 2-4x EBITDA. List it on Micro Acquire and post it on Twitter — buyers show up.

3 App Ideas He's Building Next

Lotts shared these ideas directly in the video.

1. Meal Tracker (for girlfriends) — An app that tracks whether you've eaten three meals a day. Targeting ages 18-30. Calorie tracker apps are already doing well, so the strategy is the same structure but with a narrower, more specific audience.

2. Korean Skincare Tracker — Take a photo and get your skin analyzed. People are already spending money on skin treatments, so willingness to pay is already proven in this market.

3. Chill Guy AI (boyfriend helper) — Input your girlfriend's info and get reminders like "You haven't been on a date in 3 weeks, book this restaurant." Send flowers with one tap. Revenue model: subscription + affiliate commerce.

Cost Structure

Based on a $10K MRR app:

The Key Insight

The most impressive thing about his approach is that he decides "legacy or cash flow?" before writing a single line of code.

There's a game where you raise VC, grind for 10 years, and have a 0.001% chance of becoming a billionaire. Then there's a game where you walk out with $250K cash in 6-12 months. He chose the second game and repeated it four times.

His final piece of advice was gold: "Only play games you can win. Always have an edge." For his next app, he's not entering a new market. He already has a 1.2 million Christian email list — he'll just find a different niche within that same audience. With Meta lookalike audiences, he can push CPI even lower.

The order matters. Most people go "good idea → build → market → somehow sell." Lotts goes "sellable structure → build → grow → clean exit." He designs the exit before he writes the first line of code.
