Hand-built competitor grids are a checkbox per feature: present or absent. But “has the feature” and “owns the market for it” are completely different things.
Five apps can all “have” a feature. Only one has the installs, ratings and reviews that make it the default choice. The checkbox doesn’t show that.
A spreadsheet you built last quarter is already wrong. Leaders move, ratings shift, new entrants land — and your map doesn’t.
Landing pages claim everything. Without install counts and review volume, you’re comparing promises, not positions.
Every cell is a position, and every position links to the proof.
ScanGap pulls every public app — installs, ratings, review volume, pricing, last-updated — so the field is complete and current, not curated.
A transparent score decides who actually owns a function vs. who merely lists it. Won, Contested or Open — per function, per competitor.
Every cell links to the listings behind it. Don’t trust the verdict — open the apps and check it. The evidence is one click away.
The red rows are owned and defended. The contested row is up for grabs. The open row is the function every competitor skipped — and the position you could take.
