What we measured on a device
This audit is a desk review of store listings, privacy labels, developer pages and independent articles; no app was installed or measured on a device for this report.
How we decided
Each app was scored 0 to 5 on eight criteria: core task fit (0.20), accuracy and reliability (0.15), offline use and no account (0.15), privacy (0.15), ads and price (0.10), accessibility and localisation (0.05), maintenance (0.10) and risks (0.10; Q1 to Q8). The weighted total is the sum of score times weight divided by the weights. A gap of 0.3 or less is a tie, and ties are never broken by opinion. Every score cites a store page read on 2026-11-05. Facts that a page did not state are marked unverified and scored 0 or 1. This was a desk review of store listings; no device tests were run.

This is a desk review of store listings read on 2026-11-05 from the US storefront (Apple App Store) and Google Play with hl=en and gl=US. No app was installed or tested, so echo and reverb quality, stability and export results are unmeasured. The page-reading tool returned extracts rather than full page text, so evidence is marked as paraphrase. Ratings, prices and update dates change often. Several listings did not state offline use, price or permissions, and those facts are marked unverified. No independent reviews were used.
