## 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.

## What we could not verify

- Rating and review count of EchoForge: Voice Changer were not shown on the App Store page (not enough ratings) or Google Play page.
- Price, permissions, minimum Android version and languages of EchoForge: Voice Changer on Google Play were not shown.
- Offline use and account requirement of Voloco, Edit any audio, sound: Edity, Voice Changer With Echo Effect and Voice Changer With FX Effects on iOS were not stated.
- Offline use of Voice Changer - Audio Effects, Lexis Audio Editor and Voice changer effects: echo... on Google Play was not stated.
- Accessibility features were not declared on any App Store listing except in the EchoForge description; Google Play pages showed none.
- Export formats of most Android candidates and several iOS candidates were not specified.
- No independent review or hands-on test of echo and reverb quality was used; claims come from developer listings.

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.
