Idea #15: Building No-Code iOS Apps and Selling Them on the App Store

Hey buddy,

Today's WiFi Moolah idea is for anyone who's ever thought "I have a great app idea" but assumed you needed to be a developer to make it happen. You don't.

No-Code iOS Apps as a Side Income Stream

Example: James Fleischmann — built a portfolio of 30 micro-apps and hit $22K/month in under a year using an ASO-first strategy

The Idea: Use drag-and-drop app builders to create simple, niche iOS apps and monetize them through ads, subscriptions, or in-app purchases — without writing a single line of code

Why it works:

• 97% of apps on the App Store are free, but free apps generate 98% of all mobile app revenue

• No-code platforms like Adalo and Andromo let you publish directly to the App Store

• Apple's ecosystem generated $1.29 trillion in 2024 — you don't need a big slice to eat well

• Simple utility apps (calculators, trackers, sound apps) consistently outperform "big idea" apps for solo creators

• Build once, earn passively — apps generate money through ads and subscriptions while you sleep

• Apple's Small Business Program takes only 15% on your first $1M/year instead of 30%

Time investment: 2-4 weeks to build your first app, 5-10 hours/week maintaining and launching new ones

Potential income: $500-5,000/month (portfolio approach)

Difficulty: Beginner-Intermediate

Startup cost: $99 (Apple Developer account) + $0-45/month (no-code tool)

Where I found it: James Fleischmann's Indie Hackers case study, Sebastian Röhl's public revenue reports for HabitKit ($31K+ MRR), Andromo success stories showing non-coders earning $1,200-2,000/month from content apps

Real people making real money with this:

Sebastian Röhl (HabitKit) — A German developer who quit his job, built a simple habit tracking app, and grew it to $31,500/month MRR by January 2026. His app ranks #2 for "habit tracker" on the US App Store. He built it in 2 months, spent $0 on marketing, and credits ASO and building in public on X/Twitter for his growth. HabitKit hit 500K+ downloads on Google Play alone and generated $33,000 in a single month during the New Year's resolution rush.

James Fleischmann — Built 30 micro-apps (simple, single-feature utility apps) in under a year and hit $22K/month. His strategy: find a keyword with high popularity and low difficulty in the App Store, build a tiny app around it, use the keyword in the title and description. He monetizes primarily through ads using mediation platforms for higher eCPMs. Most of his apps flopped — but the few winners stacked up.

Younes & Sarra (Morocco) — A couple with zero programming experience who started making apps on Andromo. They now earn about $2,000/month from their app portfolio, and it's the main income for their family. Each app takes them 2-3 hours to create using Andromo's drag-and-drop builder.

Tools you'd need:

• Apple Developer Account ($99/year — required, no way around it)

• Adalo ($45/mo to publish — best all-rounder for custom apps with databases)

• Andromo ($28/mo — best for content/media apps with built-in ad monetization)

• Thunkable (Free-$99/mo — best for interactive utility apps needing camera/GPS access)

• Ad network (Google AdMob — free, pays $5-7 eCPM on video ads)

• ASO tool (Astro or AppFollow for keyword research, or just use App Store search suggestions for free)

The catch:

• Apple can reject your app (missing privacy policy, low quality, or spam are common reasons)

• No-code apps have limits — forget 3D games or complex social networks

• Most apps won't be winners (James had 30 apps — only a handful drove real revenue)

• $99/year Apple fee whether you earn or not

• The median app makes under $50/month — you need a niche keyword strategy to beat those odds

• Only 17% of apps ever reach $1,000 in monthly revenue

• Updates and maintenance are ongoing as Apple changes requirements

My take:

This isn't about building the next Instagram. The money is in boring, simple, niche utility apps that solve one tiny problem. Sebastian didn't invent habit tracking — he just made a cleaner, more visual version and nailed his App Store keywords. James didn't build anything complex — he just stacked 30 small bets and let the winners carry the losers.

The real play here is the portfolio approach combined with ASO. You build what people are already searching for, not what you think is cool.

App ideas that actually make money:

• Niche habit trackers — not generic, targeted ("fasting tracker for Ramadan," "scripture reading streak") — $2.99-4.99/mo subscription

• Sound/ambience apps (rain sounds, café noise, sleep sounds) — ads + $3.99/mo premium tier

• Micro-learning quiz apps (real estate exam prep, bartender certification) — $4.99-9.99 one-time unlock

• Niche calculators (construction materials, pet food portions, tip splitting) — pure ad revenue

• Local directory apps ("best brunch in Austin," "Black-owned businesses in Atlanta") — sponsored listings at $25-100/mo per business

Money math:

Conservative (3 ad-supported apps):

• 3 apps × 1,000 daily users each = 3,000 DAU

• 3 ads per session × $5 eCPM = $45/day

• $1,350/month minus ~$45 tool cost = $1,305/month profit

Moderate (8 apps, mixed monetization):

• 5 ad-supported apps earning $300/mo each = $1,500

• 3 subscription apps with 200 subscribers at $3.99 = $2,394 (minus Apple's 15% = $2,035)

• $3,535/month minus $45 tool cost = $3,490/month profit

Aggressive (15+ app portfolio, à la James Fleischmann):

• Mix of ad and subscription revenue across portfolio

• Gross: $10,000-22,000/month

• Tool costs + optional VA for screenshots/updates: $500-700/month

• $9,300-21,300/month profit

If you want to explore this:

Month 1: Foundation

1. Sign up for Apple Developer Program ($99)

2. Create a free Adalo or Andromo account and do their beginner tutorials

3. Research 10-15 keywords using App Store search suggestions (James's method: popularity > 20, difficulty < 60)

4. Pick your first app idea based on keyword opportunity, NOT personal passion

5. Build your first app — one core feature, 5-8 screens max, clean UI

Month 2: Launch and learn

1. Create professional screenshots and a keyword-rich App Store listing

2. Submit to App Store (review takes 1-3 days)

3. Set up AdMob or in-app purchases

4. Start building App #2 while monitoring App #1

5. Read every review and iterate fast

Month 3-4: Scale the portfolio

1. Launch apps #3-5 (you'll be way faster now — each takes 1-2 weeks)

2. Kill apps with zero traction, double down on winners

3. Test Apple Search Ads at $5-10/day on your best performer

4. Experiment with different monetization models

Month 5-6: Optimize and compound

1. 5-10 apps live, 1-3 earning consistently

2. Set up ad mediation (CAS or AppLovin MAX) for higher eCPMs

3. Reinvest revenue into more apps and paid user acquisition

4. Target: $500-2,000/month and growing

Common mistakes beginners make:

• Building a "dream app" instead of simple keyword-driven utility apps

• Ignoring ASO and wondering why nobody downloads their app

• Submitting without a privacy policy (instant Apple rejection)

• Giving up after one app doesn't work (it's a portfolio game — most will flop)

• Spending 6 months perfecting one app instead of shipping fast and iterating

Red flags this isn't for you:

• You want money this week (first revenue takes 4-8 weeks minimum)

• You're not willing to spend $99 before earning anything

• You get discouraged easily (most apps will flop — that's the game)

• You want to build one "dream app" and retire (that's a lottery ticket, not a strategy)

Tomorrow's idea has even lower startup costs and you can run it entirely from your phone.

P.S. - Sebastian built HabitKit in 2 months and it now makes $31K/month. Younes and Sarra build apps in 2-3 hours from Morocco and support their family with it. What's your excuse? Hit reply and tell me what kind of app you'd build first.
