You spend months of nights and weekends building — then launch into a niche that five apps already own.
The problem was never your execution. It was picking the wrong niche.
ScanGap tells you in 60 seconds, before you write a line of code.
See what a scan looks like ↓Niches close as competitors ship — by the time you notice, the column’s red.
From a niche name to a build decision in under a minute.
Type any niche or pick from 40+ pre-scanned ones across Shopify, Wix, monday.com, Jira and Zendesk.
We crawl every app in the niche and score each function Won, Contested or Open — each backed by the actual apps.
Open functions are your opening. Build into the gap competitors left half-finished, with demand to back it.
Every app in the niche, every function it ships, scored Won, Contested or Open. The whole field on one screen — so the gap is impossible to miss.
Three answers, not a spreadsheet: is it open, who’s already won, and what’s left to build — each backed by the actual apps.
App count × concentration × rating × momentum. Few apps isn’t proof it’s open.
An app × function matrix. Each column labeled Won / Contested / Open.
Every Won / Contested / Open call comes from the same transparent method — and you can check the work behind any of them.
Every public app listing — install counts, ratings, review volume, pricing, last-updated. Nothing sampled, nothing guessed.
Won / Contested / Open from one explicit calculation: market concentration × rating quality × momentum. No black box.
Each verdict points at the actual apps behind the call — open them and verify it yourself. Don’t take our word for it.
The map reflects the market today, not last year. A niche that closes this month shows red next week.
Yes — you can scan your first niche free, no credit card. You get the full saturation score and function matrix before deciding anything.
We re-crawl the marketplaces weekly, so app counts, ratings and the Won/Contested/Open calls reflect the field as it stands now, not a stale snapshot.
A function is “won” when one or a few apps clearly dominate it on coverage, ratings and review volume — leaving little room for a new entrant. Each call links to the actual apps so you can judge for yourself.
You can request a niche and we’ll scan it. We already have 40+ pre-scanned, and the crawler can map most categories on demand.

No. You pick a niche and read a color-coded matrix. The output is a build decision, not a data dump — green means open, red means taken.
Four concrete outputs, every time. Read them in a minute, decide before you write a line of code.
