## What is DriftWatch?

DriftWatch is a captain's best friend for a good night of sleep. Often the captain sets anchor for the night and keep waking up regularly to confirm that the anchor is still preventing the boat from drifting. 

Some boats/yachts have anchor alarm on their GPS system. Unfortunately, it is not rare that the integrated GPS system is inaudible from the captain's bed. 

With DriftWatch running on your IOS device, you can have it near your bed and be confident that it will warn you if you drift outside of the established boundary.

DriftWatch is the perfect complementary mean that provides peace of mind when anchored.

DriftWatch is simple and easy to use. 
---------------------------------------------------------------------------------------------

Note: Your IOS device should be connected and charging when using DriftWatch for an extended period of time either as a foreground or background application. The application keeps monitoring your location using the device's GPS which drains the battery faster than normal. Fortunately DriftWatch monitors your battery level and alerts you when a certain battery level is reached when unplugged.

### 3/5 — Pratique mais ....

*2020-08-16*

Le son n’est vraiment pas assez fort ! Si nous ne pouvons entendre d’alarme alors à quoi bon cette application ??? 

À corriger et ce très rapidement c’est une question de sécurité !

**Developer response:** La dernière mise à jour produit un son beaucoup plus fort.

### 4/5 — Génial !

*2020-08-07*

Super application !!! Très fidèle et je me sens en sécurité lors de mes nuits passe sur l’eau !! La seule chose depuis la dernière mise à jour le son des alarmes est beaucoup plus basse et j’ai aucun moyen de la mettre plus forte . De plus je ne vois plus les noms des alarmes ils n’apparaisse plus je la choisir à l’écoute et au hasard !

**Developer response:** La dernière version produit un son beaucoup plus fort.

### 5/5 — Parfait

*2017-07-23*

Fonctionne très bien , bien pratique et très simple ! Idéalement laisser le cellulaire sur le chargeur pcq ça draine la batterie

**Developer response:** Assurez vous de bien régler l'alerte de bas niveau de la batterie.
