10 Mobile App Ideas That Make Money in 2026 (With Revenue Data)

Most lists of mobile app ideas are written from a brainstorm. This one starts from revenue data. We looked at 61,814 apps that reached a top chart on the US App Store or Google Play, grouped them into niches, and kept only the app ideas where a meaningful share of apps already make money. Ten made it. Five ideas from our own earlier version of this list didn't, and we explain why at the end.

Across the whole catalogue, 17.9% of apps earn more than $1,000 a month. Every idea below either beats that rate or has an unusually large number of small apps that still earn. That second signal matters most if you're one person building with AI tools, because it means you don't need a huge audience to get paid.

How to Read the Numbers

Every idea gets a card with figures from our catalogue on October 12, 2026:

• The big number is the share of apps in the niche with estimated revenue above $1,000 a month. The thin line on each bar is the average app, at 17.9%.
• Typical earner is the median monthly revenue among the apps that earn.
• Small apps earning counts apps that earn more than $1,000 a month with 10,000 or fewer monthly downloads. It's the closest thing to proof that a small newcomer can get paid.
• New this year, earning counts apps released in the past 12 months that already earn.
• iOS and Android show the same earning share for each store. An app on both stores counts once per store.
• Small apps earning here are a few real examples from that group.

Revenue and download figures are estimates rounded into bands, so treat them as orders of magnitude. How we build them is on our methodology page.

The 10 App Ideas

1. Collectible and nature identifiers

Point the camera at a coin, a sports card, a bird or an antique and get a name and a value. More than half of these apps make money, three times the catalogue rate, and 21 of them launched in the past year. Collectors pay because the answer is worth money to them: a card scanner that says "this one is worth $80" pays for itself.

The build is mostly a vision model plus a good reference database. The database is the moat. Pick one collection type the big apps handle badly, like comics, stamps or vintage watches, and go deep.

2. AI note takers and transcription

Record a meeting, a lecture or a voice memo and get clean notes back. The typical earner here makes more than in any other niche on this list. The top apps are general-purpose, so the opening is a single audience with its own vocabulary. One small app on our list does nothing but take notes on sermons.

It's very buildable: a speech-to-text API, a summarising prompt and a tidy export. Your costs grow with every minute of audio, so price per usage or cap the free tier from day one.

3. Invoice and estimate makers for trades

Contractors, cleaners and detailers want to send a quote from the driveway and get paid without a laptop. On Google Play, 52.8% of these apps earn, against 31.1% on iOS. Most earners have small download numbers, which tells you each customer pays well. A business owner barely notices $20 a month if one extra job covers it.

Very few new apps have broken in during the past year, so you need a sharp angle. Building for one trade, with its own line items and its own estimate template, beats another generic invoice maker.

4. Plant identification and care

The split between stores is the story here. On iOS, 35.6% of plant apps earn. On Android, 16.2% do. Plant owners on iPhone pay for identification, watering schedules and disease diagnosis, and the typical earner makes $80K a month.

Plain identification is crowded. Diagnosis ("why are my leaves turning yellow?") and care for one kind of plant, such as orchids, bonsai or vegetables in a given climate zone, still leave room.

5. Hobby tools: fishing, hunting, boating, astronomy, crafts

Fishing maps, hunting GPS, marine navigation, stargazing charts, crochet pattern counters. Hobbyists spend money on their hobby without much thought, and an app is cheap next to a rod or a telescope. 76 apps here earn with small download numbers, one of the highest counts on the list.

Start from one activity in one region. A tide and bite-time app for one coastline is easier to make good than a fishing app for the whole world.

6. Faith apps: Bible, prayer, devotionals

A large, loyal audience that opens the app every day. The niche is big and still welcoming newcomers: 23 apps released in the past year already earn, more than in any other niche here. Many of them combine scripture with something new, like an AI chat, a short-video feed or a daily widget.

Content quality and tone matter more than features. You need someone who knows the audience, because users notice when an app gets the theology wrong.

7. Personal finance micro-tools

Skip the full budgeting app. The earners we see do one money job: tracking mileage for tax, cancelling forgotten subscriptions, splitting bills, logging fuel costs. With 90 small earners, this niche has more apps earning on small download numbers than any other on the list. On Android the earning rate is 29.8%, against 14.1% on iOS.

The math has to be right and the privacy story has to be clear. Get either wrong and your reviews will tell everyone.

8. Niche sport tools

Golf GPS and scorecards, disc golf course maps, bowling stats, archery sight tapes, pickleball video review. Each sport has a committed crowd that the big fitness apps ignore. On Android the earning rate reaches 34.5%.

Only one app released in the past year earns, so the established players hold on well. Win with one sport the leaders don't cover, or with one feature they do badly, like swing analysis or shot tracing.

9. Exam prep for one licence or certification

CDL, DMV permit, NCLEX, EMT, TEAS. People studying for a licence pay because failing costs them time and money. Earners in this niche tend to have small download numbers, since each app serves one exam.

The build is a question bank, spaced repetition and a practice-test mode. The hard part is the questions: they have to match the current exam, and you have to update them when it changes.

10. Specialised forecasts

General weather apps are crowded. Only 9.4% of the 1,675 general weather apps we track earn. Forecasts built for one activity earn at more than twice that rate: marine and wind forecasts for sailors, drone flying conditions, weather for hunters, snow reports for skiers.

The value is in reading the forecast for a decision ("can I fly today?"), not in the raw data, which is easy to get. That makes it a good fit for a fast build.

Ideas We Cut, and Why

An earlier version of this list had twelve ideas. We checked each one against the catalogue, and five didn't hold up:

• Perimenopause tracker: only 5 apps in the catalogue mention it. We can't tell whether that's an opening or a sign of weak demand, so we won't call it either.
• Postpartum recovery coach: 17 apps. Too few to read.
• Caregiver and medication coordination: 62 apps, and only 11.3% earn, below the catalogue rate.
• Pet health apps: 14% earn, below the catalogue rate, and many of the earners are companion apps for pet hardware rather than care tools.
• Local-language productivity: our catalogue doesn't split apps by language, so we can't check it. It may still be a good idea. We just can't show you the numbers.

How to Check an Idea Before You Build

The numbers above describe whole niches. Your idea is narrower than that, so check it yourself:

1. Find the apps already in your pocket. Search the niche in Trend Apps and look at revenue next to downloads. Small download numbers with real revenue is the pattern you want.
2. Read the 1 to 3-star reviews of the top three. The complaints that repeat are your feature list.
3. Look for new earners. If nothing released in the past year earns, the leaders are hard to dislodge, and you need a sharper angle.
4. Pick a store. Several niches here earn very differently on iOS and Android. Launch where your niche pays.

Frequently Asked Questions

What are good mobile app ideas in 2026?

The ones where apps already earn. Collectible identifiers (54.2% of apps earn), AI note takers (40.0%) and trade invoice makers (38.5%) lead our data. Personal finance micro-tools and hobby tools have the most small apps that still earn.

Which app ideas make money for a solo developer?

Look for niches with many small earners: apps making more than $1,000 a month on 10,000 or fewer monthly downloads. Personal finance micro-tools (90), hobby tools (76) and faith apps (68) have the most. Revenue doesn't need a huge audience in those niches.

What AI app ideas make money?

AI earns where it removes a step the user hates. Identifiers turn a photo into a name and a price. Note takers turn an hour of audio into a page. Plant apps turn a photo of a sick leaf into a fix. A general AI chat app is the opposite case: crowded, and expensive to run.

Which of these app ideas are good for vibe coding?

Note takers, exam prep, finance micro-tools and specialised forecasts have narrow scope and well-known patterns, so an AI assistant can handle much of the build. Identifiers and plant care need a reference database you'll have to build up. If you're picking your first project, read App Ideas for Vibe Coders.

Are there app ideas that don't exist yet?

Rarely, and that isn't the goal. A niche with no apps usually has no buyers. Every idea on this list has apps already, and that's how we know people pay. The opening is a narrower version of an idea that already earns.

Should I build for iOS or Android first?

Check your niche. Plant apps earn more than twice as often on iOS. Trade invoice makers, finance tools and niche sport tools earn more often on Android. Launch on the store where your niche pays, then add the second one.

How much does a niche app make per month?

Among the apps in this list that earn, the typical (median) app makes $20K to $100K a month depending on the niche. Most apps don't reach that. Across the catalogue, 82.1% earn $1,000 a month or less.
