Most lists of app ideas come from companies that sell app development or app builders. They're full of "an AI fitness coach" and "Uber for X", and not one of them tells you whether anyone searches for the thing, or who you'd have to beat to show up.
So we did it the other way round. We started from the searches people already type into the App Store and Google Play, and kept the ones where the apps ranking today are tiny, stale or both. Every app idea below comes with the search behind it, its Applyra scores, and the three apps holding the top of the results on the day we measured.
The short version: on these 25 searches, the median #1 app has 11 ratings, and two thirds of the apps in each top five already charge for something. People search, people pay, and nobody owns the search yet.

How we picked them
We started from every US search Applyra has measured on both stores, 554,066 phrases of two words or more. We kept those with a traffic score of 45 or more and a difficulty of 35 or less, where at least three apps in the top 30 target the phrase (a category, not a brand), and where no app in the top three of the search a niche rests on has tens of thousands of ratings. On November 6, 2026 we read the live top 10 of 79 finalists, and kept a niche only if an app released in the last 18 months already sits in that top 10, and if one developer can build it without expert content. Ratings are the US App Store count, or the worldwide count on Google Play. The traffic score tracks Apple's own popularity data closely.

Health and fitness app ideas
4-7-8 breathing timer
App StoreGoogle PlayA guided 4-7-8 breathing timer for falling asleep and calming down: haptic pacing, a sleep mode with the screen off, and a widget that starts a cycle in one tap.

- #34-7-8 Breathwork: 478 Reset4 ratings · ★ 4.8 · updated Nov 2026

- Proof a newcomer gets in:
- Four of the App Store's top five were released in the last 15 months, and the whole top six has 20 ratings between them.
- How the shelf charges:
- On Google Play, the one funded app in the top three, Breathwrk, sells in-app purchases and sits at 2.2 stars over 2,698 ratings. A 2.2 average says its users aren't getting what they came for.
- Your way in:
- Do one exercise perfectly instead of fifty badly. Free cycles, a one-time unlock for sleep mode and the widget, and the phrase in your title on both stores.
75 Soft challenge tracker
Google PlayApp StoreA tracker for the 75 Soft challenge: the daily rules as a checklist, a day counter, progress photos, and a reminder before the day runs out.

- Proof a newcomer gets in:
- Reset75 was released in April 2026 and already ranks #3 on Google Play with 673 ratings. The #1 launched in November 2025.
- How the shelf charges:
- All five apps in Google Play's top five sell in-app purchases. A challenge app sells the 75 days, then the next challenge.
- Your way in:
- On the App Store the same search is a fight: a difficulty of 46 and a habit tracker with 148,609 ratings at #4. Launch on Google Play first. And 75 Hard is a trademark, so describe the challenge without borrowing the brand.
Rucking tracker
App StoreA tracker for rucking, walking with a weighted pack: pack weight, distance and pace, with calories that account for the load.
- rucking trackerTraffic 65MediumDifficulty 15Easy

- Proof a newcomer gets in:
- Ruckaroo was released in January 2026 and already ranks #3 with 576 ratings. RUCKR, from May 2026, is #2.
- How the shelf charges:
- Four of the top five sell in-app purchases, and the leader has fewer than 1,000 ratings.
- Your way in:
- A step counter knows nothing about the 20 pounds on your back. Read the walk from the phone, add the pack, and sell training plans for ruck events as the paid tier.
DBT diary card
App StoreA digital DBT diary card, the daily sheet therapists hand out in dialectical behavior therapy: urges, emotions and skills used, filled in under a minute and exported for the next session.

- Two of the top four were released in 2026. On Google Play, the #1 for the same search launched in July 2026.
- How the shelf charges:
- The App Store's #1 charges $4.99 upfront and hasn't been updated since 2019. Every other app in the top five sells in-app purchases.
- Your way in:
- Stay a journal: no diagnosis, no advice, no AI therapist. Therapists assign this card, so a clean export they can read is the feature that gets you recommended.
App ideas for work
KML, KMZ and DXF viewer
App StoreA viewer for the map and drawing files people receive by email: KML and KMZ from Google Earth and survey tools, DXF from CAD. Open, measure, share, done.

- The App Store's whole top three for “kml viewer” was released in the last 13 months, with 4 ratings between them. On “dxf viewer”, seven of the top ten are less than 18 months old.
- How the shelf charges:
- Two of the top three sell in-app purchases, and on “kmz viewer” two older viewers sell for $0.99 and $1.99 upfront.
- Your way in:
- Google Earth ranks too, which proves the demand. It is built to explore a globe, though, and a fast viewer that opens one file and measures one field is the opening. Offline maps and PDF export are the paid tier.
Calculators for the trades
App StoreGoogle PlayCalculators for the job site: roof pitch from the phone held against a rafter, drywall sheets for a room, ohm's law for electricians. One app per trade, each answering in two taps.

- The App Store's #1 for “roof pitch” was last updated in July 2015, and two roof pitch apps released in July and August 2026 already sit at #4 and #5. On Google Play, the whole top five for “drywall calculator” was released since August 2025.
- How the shelf charges:
- Four of the App Store's top five for “roof pitch” sell in-app purchases.
- Your way in:
- Contractors pay for tools that quote faster. Turn the calculation into a materials list with prices, and you are selling an estimate, not a calculator.
CNC simulator and machinist calculator

- How the shelf charges:
- Machinists pay upfront: the #4 and #5 simulators sell for $9.99, and CNC Machinist Calculator Pro sells for $14.99 with 681 ratings.
- Your way in:
- Trade school students search for practice, and shop floors search for answers. A simulator with a library of practice parts is the student product, the calculator the professional one.
iPad monitor for USB and NDI cameras
App StoreTurn an iPad into a field monitor: plug in a USB camera or capture card, or open an NDI or RTSP stream from the network, and see it full screen with a grid and focus peaking.

- USB CAM was released in July 2026 and ranks #3 with a single rating. On “ndi monitor”, the #2 app averages 1.1 stars over 47 ratings and has not been updated since July 2020.
- How the shelf charges:
- NDI Monitor sells for $9.99 upfront, and CamX sells in-app purchases with 296 ratings. Video crews buy their tools by the job.
- Your way in:
- iPads have accepted USB cameras since iPadOS 17, in 2023, and the shelf is still thin: the top three for “usb camera” have 310 ratings between them. One app that handles USB, NDI and RTSP is the one that stays installed.
Per diem tracker

- Proof a newcomer gets in:
- GSA Per Diem was released in June 2026 and already ranks #2 with 2 ratings. The #1 has not shipped an update since September 2024, and the #4 averages 1.2 stars.
- How the shelf charges:
- Nobody in the App Store's top five sells anything yet. On Google Play, the #2 sells in-app purchases. Business travellers expense their tools, so a paid tier is an easy sell.
- Your way in:
- Two of the App Store's top six aren't about travel allowances at all. Use the GSA's public rates, count days from location, and speak to the people the shelf ignores: travelling nurses and truck drivers claim per diem too.
Continuing education tracker
App StoreA tracker for the continuing education hours licensed professionals owe every renewal cycle (nurses, CPAs, pharmacists, social workers): hours per licence, certificates scanned, and a warning before the deadline.

- Proof a newcomer gets in:
- OnTrack CE was released in March 2026 and already ranks #1 with 22 ratings. Eight of the top ten were released in the last 18 months.
- How the shelf charges:
- The top three all sell in-app purchases, and the #3 also charges $0.99 upfront.
- Your way in:
- Start with the professionals whose employer does not track it for them, such as travelling nurses who hold a licence in several states, and the renewal reminder becomes the reason they keep the app.
PTO tracker

- How the shelf charges:
- On Google Play, the #4 sells for $1.99 and the #5 sells in-app purchases. Day Off, the one established app, ranks #2 on Google Play and #3 on the App Store.
- Your way in:
- HR software tracks the balance for the company, not for the person planning a holiday. Do the accrual maths for the employee, with a calendar that shows what each trip costs in days.

- Two of Google Play's top five sell in-app purchases. On the App Store, FlyFin, a funded tax service, ranks #2 with 549 ratings.
- Your way in:
- The rates are public and set by the IRS. The hook is the reminder that a payment is due on the 15th, so make the calendar, and the amount to set aside from each invoice, the product.
IOU tracker

- How the shelf charges:
- All five apps in the top five sell in-app purchases, and the leader has 811 ratings.
- Your way in:
- Splitting a dinner is a crowded shelf. Remembering the $200 your brother borrowed in March isn't. Keep it personal, and make the nudge message the feature.

- How the shelf charges:
- Four of the top five sell in-app purchases, and SuperTrader shows the ceiling with 1,208 ratings at #2.
- Your way in:
- Traders import from their broker or they don't use the app. CSV import from the big US brokers on day one beats any chart.

- Three of the App Store's top five sell in-app purchases, and the #5 charges $0.99 upfront. On Google Play, the #2 sells in-app purchases too.
- Your way in:

- Four of the top five sell in-app purchases. Beekeepers already spend on hives, suits and treatments.
- Your way in:
- Inspections happen with gloves on and bees in the air, so voice notes that fill the form beat any feature list. This one is App Store only: the same search barely registers on Google Play.

- Proof a newcomer gets in:
- Nine of the top ten were released in the last 18 months, and the #1, FJR, is two months old.
- How the shelf charges:
- Three of the top five sell in-app purchases.
- Your way in:
- Prayer times are calculated from your coordinates with published methods. The hard part is the wake-up itself: a task to dismiss the alarm, a gentle recitation, and a streak.
Niches we left out, and why
Plenty of searches passed the numbers and still didn't make the list. They're worth knowing, because they look like gaps and mostly aren't.
- Exam prep. "ap us history" (traffic 84, difficulty 27) and "ap bio" (84, 19) are as open as anything above, but every answer has to be right, and that's expert content one developer can't check alone.
- Health apps that make medical claims. "mole check" (70, 28), "lab values" (73, 27) and "iv drip rate" (67, 8) look easy. Apple reviews medical apps more strictly, and a wrong number there hurts someone.
- Giants hiding behind easy scores. "oil change" scores 66 and 34 on the App Store, but its top three are Valvoline, Firestone and CARFAX, the last with 128,645 ratings. On Google Play, "insect identifier app" (63, 16) is led by Picture Insect with 40,049.
- A shelf nobody updates and nobody enters. "cvc word" (82, 31), the three-letter words children learn to read with, has a top five that hasn't shipped an update in over a year, yet no app from the last 18 months has reached the top ten. It may be the easiest gap here, but we couldn't show the store lets a newcomer in, so it isn't in the 25.
- Memes. "oiia cat" (82, 5) and "gugu gaga" (79, 21) have the traffic of a trend and the shelf life of one.
How to validate an app idea yourself
You don't need our list to do this. It's app market research with the store's own data instead of a survey, and it takes ten minutes per idea:
- Start from the phrase. Type your idea into the App Store search bar and write down what autocomplete offers. Those are the words people actually type, and the only ones worth scoring.
- Score it. The free keyword tool gives traffic and difficulty for any search on both stores, without an account. Traffic over 45 with difficulty under 35 is where this list starts.
- Read the top ten. Open the apps that rank: how many ratings, when they last shipped an update, what they charge. A top three with a few dozen ratings and an update from 2023 is an invitation.
- Look for a newcomer. One app released in the last year and already in the top ten proves the store lets a new app in. No newcomer, and you're guessing.
- Size the whole niche. Niche Analysis groups the searches around a topic into sub-niches and scores each one, and the free plan includes one a month.
- After launch, check where you landed. The app rank checker shows your position for a search in any country, and a free account tracks five keywords every day.
The whole method, from the first search to the 100 characters of your keyword field, is in our App Store keyword research guide.

Frequently asked questions
How do I find app ideas that people actually search for?
Start from the store's own search data rather than a list of trends. Pick searches with real demand and low difficulty, then read who ranks in the top 10: if the top apps have a handful of ratings and an app released in the last year already made it in, the store is letting new apps through.
Which app ideas make money in 2026?
The ones where the apps already ranking charge for something and the buyers have a reason to pay: professionals with a job to do, such as per diem, continuing education or CNC tools, hobbyists who already spend on their hobby, and challenge apps sold by subscription. In this study, 66% of the apps in each niche's top five already sell something, while the median #1 app has 11 ratings.
What simple app ideas can a solo developer build?
Calculators and trackers built around one job: a per diem tracker for business travel, a cap rate calculator for real estate investors, a soap making lye calculator, a beekeeping hive log or a tin whistle tutor. Each has real search demand on the App Store and a top three with fewer than 500 ratings, so one developer can compete.
What makes an app niche underserved?
Real search demand meeting a weak shelf. In this study that means a traffic score of 45 or more, a difficulty score of 35 or less, at least three apps in the top 30 targeting the phrase, no app in the top three with tens of thousands of ratings, and a newcomer from the last 18 months already in the top 10.
Why do apps with almost no ratings rank first in these searches?
Because nobody bigger targets the exact phrase yet, and the App Store ranks an app whose name matches a search before it has reviews. Apple's late-July 2026 reshuffle of App Store search, which knocked a large share of ranked keywords out of the top 100, left more of these gaps open.
Can I download the list of app ideas?
Yes. The CSV lists all 25 niches and the 44 searches behind them, with Applyra's traffic and difficulty scores, the top three apps and their ratings, and how many of the top 10 were released in the last 18 months, all measured on November 6, 2026. It's free to reuse under CC BY 4.0.
