Mabel

Mabel is a simple, fully offline app for instructors to track attendance for lesson groups (yoga, drawing, and similar small-group classes). Core features: Groups & members — organize members into groups with recurring lesson times; take attendance with one tap per lesson Trial-lesson tracking — automatically tracks how many lessons a trial member has attended, with a configurable threshold before they become a full member (per group, or combined across all their groups) Season workflow — import a full roster at the start of a new season, replacing the previous one, so data isn't kept longer than needed Encrypted backups — one-tap backup/restore, always password-protected (AES-256) Optional contact sync — save members as phone contacts, with a clear label and full user control (opt-in, reversible) PIN lock — secures the app itself with a 4 digit code Bilingual — full Dutch and English UI Privacy-first — no account, no server, no analytics or tracking; all data stays on the device unless the user exports or backs it up themselves Missing any features?
