Biometric Roll Call
Read full descriptionHide full description
RollCall turns your iPhone or iPad into an on-device attendance scanner. Enrol people once, start a session, and the app marks them present as they appear - ideal for classrooms, events, and shift teams. Features: Live scanning - Use the device camera to recognise enrolled faces and record attendance in real time. Smart rosters - Group people by class, shift, event, or any list you need. Reports & export - Finish a roll call and share a PDF summary or CSV with status, timestamps, and GPS via Mail, AirDrop, or Messages. Session history - Searchable log of every roll call. Works offline - Scan and save with no internet. Suited to sites, trips, and poor WiโFi. IP cameras - ONVIF discovery and RTSP (including brand stream presets). Main/high-res streams work best for recognition at distance. Privacy: Face detection and matching run only on your device. No face images or biometrics are sent to or stored on our servers. Facial profiles are protected with AES-GCM and kept in the device Keychain. Spend less time on the register. Download RollCall and run attendance on-device, securely.

Verdict
The clearest difference is in-app purchases: Biometric Roll Call at none against Keyboard Theme's 2. Keyboard Theme's advantage is iOS requirement (15.0 vs 17.6). On price, update cadence, ads and device support there is nothing between them.
