Build an Android recorder designed around file ownership and capture reliability rather than transcription or cloud lock-in. It writes recoverable recording segments directly to a user-selected folder, continuously verifies that audio is being captured, displays prominent failure warnings, and supports automatic copying to removable storage, a computer, or the buyer's chosen cloud folder. Standard filenames, timestamps, selectable formats, checksums, and a migration utility make recordings usable by editing, evidence-management, and archival workflows.

Recent Android storage restrictions and device-specific ecosystems increasingly place recordings in inaccessible app-private folders. The signals span several recorder brands and multiple years, showing that portability, recovery, and dependable long-form capture are broader needs rather than one product's isolated defect.
