Acadly Here attendance system is built upon a proprietary mesh network based technology that utilizes only Bluetooth and WiFi on the attendance taker's and attendees' devices. As long as there is internet connectivity and required permissions are granted to the application, the app will work seamlessly.
Once the host (one taking the attendance) starts taking the attendance, attendees in their proximity are marked present instantly. This creates a local mesh network which makes sure everyone physically close to the attendance taker/ admin is marked present.
And yes, we don’t use GPS location tracking. You can learn more about that here.
