01 / Overview
A clearer note. A more focused practice.
TuneLoop is an Android instrument-tuning application developed by Fortis Mundi Studios.
Its current Google Play listing describes microphone-based pitch detection, reference sounds and practice tools for beginners and experienced musicians.
The published listing names eight instrument profiles: acoustic guitar, ukulele, banjo, violin, electric bass, cello, mandolin and double bass. Standard tunings are free; optional TuneLoop+ purchases are handled through Google Play.
Why we built it
Tuning and practice involve several connected tasks: hearing a reference pitch, checking a string, keeping time and recognizing notes. TuneLoop brings these tasks together in one Android application.
Its published product description emphasizes clear tuning feedback and accessible practice tools. This explains the product’s purpose without assuming an undocumented founding story.

Sources & limitations
Public listing information was checked, but the application binary, subscriptions and purchase restoration were not tested. Do not infer release-candidate readiness from the website.
The existing legal homepage still uses pre-release wording despite the public Play listing. Existing privacy, terms, support and deletion pages remain authoritative external destinations until a reviewed migration.
Pitch feedback depends on microphone quality, background noise and instrument range. Follow instrument and string guidance and stop if uncertain about safe tension.
Legal & privacy
Published documents remain at their authoritative project destinations.
