Jotron EPIRB is a tool to configure the Jotron Tron AIS EPIRBs. It will also allow read back of already programmed beacons. For full programming functionality, a separate license is required. This license is granted automatically to direct Jotron customers who have completed the Jotron Tron AIS EPIRB training course. To ease programming of beacons, familiarize yourself with the location of the NFC reader on your phone and place it as close as possible to the NFC location on the beacon. This tool does the same job as the TronLink EPIRB desktop programming software.
Keylet

Keylet is the privacy-first authenticator that fills your 2FA codes right above the keyboard — without opening the app, and without ever showing a code on screen. From the makers of Authenticator+ — and switching is effortless. Import your accounts in seconds, straight from Authenticator+, Google Authenticator, Authy, Microsoft, 1Password and more — or even from a single screenshot, with no second device needed. Your secrets never leave your phone. Everything lives in an encrypted, zero-knowledge vault (AES-256-GCM) that only you can open. No account. No cloud. No tracking. No ads. WHY KEYLET • AutoFill, done right — tap a verification-code field and Keylet offers the right code. It fills it; it never displays it. Nothing to shoulder-surf. • Import in seconds — from Authenticator+, Google Authenticator, Authy, Microsoft, 1Password, a backup file, or a screenshot. No second device required. • Multiple vaults — keep work and personal completely separate, each encrypted on its own. • Encrypted sharing — hand a code to someone you trust over end-to-end encryption, with a self-destructing expiry. • Backed up, safely — automatic daily encrypted backups on your device, plus password-protected export. No cloud needed. • Yours to organise — biometric lock per account, categories, recovery keys and home-screen widgets. • No ads. Ever. Unlimited accounts, free. Keylet keeps your second factor exactly where it belongs: in your hands, encrypted, and out of sight.

Verdict
The clearest difference is in-app purchases: Jotron EPIRB at none against Keylet's 3. Jotron EPIRB also leads on iOS requirement (14.0 vs 16.4). Keylet's advantage is update cadence (every 5 days vs every 8 months). On price, ads and device support there is nothing between them.
