## What is OLAS?

Exposure OLAS Mobile App – Smart Safety at Sea
The Exposure OLAS mobile app is your essential onboard safety companion, designed to track OLAS transmitters (OLAS Tag, OLAS T2, or OLAS Float-On) and ensure all crew, family members, kids, and pets remain safely onboard.

If the virtual tether between your mobile device and a transmitter is broken, OLAS immediately triggers a high-volume alarm and logs the GPS location to assist in rapid recovery. In the event of a prolonged rescue situation, OLAS provides a clear and concise location reference for emergency services.

For solo sailors, SOLO MODE adds an extra layer of security by automatically sending an SMS with vessel details and coordinates if an overboard incident occurs.

The OLAS app offers direct tracking of transmitters or can be used in conjunction with powered OLAS receivers for enhanced functionality. When connected to a receiver, the app acts as a remote control and additional alarm system, allowing you to manage alarms, select transmitters to track, and customise settings.

Advanced Features with OLAS Receivers (Guardian & N2K):
- Helm Tag Calibration – Set up for seamless operation.
- Engine Immobiliser Activation – Enhance security with automatic engine shut-off.
- Customisable Transmitter Names – Easily label and manage multiple devices.
- Battery Status Monitoring – Ensure all OLAS tags are charged and ready.
- Cut-Off Switch Control – Enable/disable the engine kill switch for specific transmitters.
- Tag Management – Activate, disable, or pause tracking as needed.

### 2/5 — Manda solo 1 SMS per salvare un uomo in mare???

*2023-01-06*

L’applicazione potrebbe essere migliorata notevolmente. Ad esempio nella modalità “solo”
Che servirebbe nel caso una persona navighi da sola, in caso di caduta in mare l’app invia un SMS ad un numero di cellulare selezionato dall’utente. È evidente che sarebbe utile poter inviare SMS a più numeri e anche avere un invio di più messaggi, perché un solo SMS potrebbe essere ignorato, non capito e quindi cancellato per errore.
E’ un peccato che questa e altre migliorie non siano implementate. lo strumento va quindi utilizzato conoscendole bene le limitazioni, e non gli affiderei la vita di una persona. 
spero che gli sviluppatori possono in futuro migliorare queste pecche, anche se sono parecchi anni che praticamente non vedo miglioramenti.
