TaffyQSL is a free and open-source amateur radio logbook for Android, inspired by TrustedQSL. It allows radio operators to manage contacts using the ADIF format and sign QSOs in workflows compatible with Logbook of the World (LoTW). Certificates and private keys are stored locally and protected using the Android Keystore, with encrypted backups on the device.
