How we chose
We looked at each app's current App Store and Google Play listings on 21 October 2026: what it tracks, platforms, pricing model, how recently it was updated, and who it's built for. We didn't accept payment for placement. CarO is our own app, so we've listed it first but tried to be specific about where other apps are a better fit. Store ratings change constantly, so we don't rank on them.
