About Sailsafe Pro. Anchor alarm.
Sailsafe is an application designed to increase safety in the anchoring of small and medium-sized ships.
It lets you stablish a safety zone around your anchor and activate an alarm that will alert you in case your ship leaves that zone at any given time (very common situation when anchor drifting occurs or the chain breaks). You will be able to see where the boat is located on the map at any moment, which is very useful if it is dark or visibility is reduced.
The safety zone can be set just indicating a radius.
In PRO version, you can also specify an aditional exclusion zone to detect, for example, changes in wind direction that could put our boat at risk if, for example, the coast is positioned itself to leeward.
Sailsafe has been designed to maximize the safety after anchoring. Therefore, once the alarm is activated, not only the position of the ship is checked, but also the level of the battery in the mobile device or the state of the GPS signal. If any of these parameters fails, then the app will produce an audible alarm to inform about the specific problem. Thus, after setting the alarm you can relax and trust Sailsafe. It will be watching for you.
Features:
- It runs in the background.
- Main screen shows useful information:
1. Current position (latitude, longitude and accuracy of the measure).
2. Current security radius.
3. Current drift.
- Set graphically and easily a security zone with an optional exclusion zone.
- Wind forecast included (48h). You will be warned if the boat is expected to be out of the security zone due to a wind change.
- The ship and the security zone are always shown over a map with optional satellite view.
- Once the alarm is set, you can adjust the anchor position in case it is not correct. Just indicate the actual bearing (read it from the compass) and estimated distance between the ship and the anchor (surface distance).
- Option to ignore the current volume of the device and set it to the max when the alarm is triggered.
- Option to set a minimum battery level. When reached, the alarm is triggered.
- Option to allow automatic alarm re-launch after a false positive.
- Option to keep the screen on while the alarm is activated.
- Option to call a phone number when the alarm is triggered.
- Remote commands:
1. An incoming call from a defined phone will reset the alarm.
2. Send a SMS with the word STATUS to the on board device and it will respond with another SMS containing useful information about the location of the ship.
- After a set number of seconds without GPS signal, the alarm is triggered.
- Option to mute alarm tone after a set number of minutes (to avoid annoying pets in the boat if the alarm is triggered and nobody is on board).
- Option to set the measurement unit (feet or meters).
- Three modes of operation:
1. Normal. GPS readings every 10 seconds. Simple algorithm to discard odd positions. (Save battery when the device is not charging).
2. Fine. GPS readings every 2 seconds. Complex averaging algorithm based on accuracy and time of the last 10 GPS readings to discard odd positions making the whole system smooth and robust. More power consumption.
3. Continuous. GPS readings every 1 second. Same algorithm as in fine mode. Optimus for adverse weather conditions. More power consumption.
4. Poor GPS signal mode.
- When re-enabling alarm, if ship moved less than 150 meters, you can opt between keeping last anchor position (useful after a false alarm) or using the actual GPS reading.

App History & Updates
What's Changed
New alarm tones.
Alarm sound now linked to multimedia volume. Working on "Do not disturb" mode.
Automatic recovery mode working for GPS signal lost.
2 new options to set: (a) the time in seconds the alarm wait to trigger after the GPS signal is lost and (b) the time in minutes the alarm will be ringing (after this time alarm mutes itself).
When working with feet units the interior circle value was reset everytime to 0 after setting it. Fixed.
More space to set larger radii in the main screen.

Haha love the pet reference is in the feature list. I have loved this app for years and thanks for the new features around this issue. Now can we get a way to type in numbers instead of just sliders it's to difficult to be exact.

Great app. Reliable and easier to use than others I've tried.especially as I activate it after I've established the anchor.

It has flaws that makes it useless. Until they are fixed, two stars it is. Here's the anecdotal story that illustrates the point: we set an anchor alert with SailSafe on my phone to call another phone, and went ashore. When we came back to the boat my phone had been alerting for hours that there was no GPS signal. There are several problems with this: 1. When the GPS signal is lost, it's not the end of the world. The signal will come back. The app should wait a configurable number of minutes before alerting. 2. If the app alerts on GPS signal lost anyway, it should shut up and go back to work once the signal is back. It doesn't. 3. If the app alerts on GPS signal lost, it should also call the emergency phone. It doesn't. 4. The alarm should shut up after a configurable number of minutes. No need to annoy the boat cat for hours if we are not onboard. In addition, the app should alert even if the phone is in 'do not disturb' mode. To the author: please fix these issues and make your app great. [Written at 3am after another "GPS signal lost" alarm.]

I like generally the app but sometimes lose the GPS signal and i am not reable to get it again until i restart the phone. Thats meaning also to lose the initial position. I would love to have chance also to input manually coordinate. Can you update this feature?

Can call any phone and play a loud sound to alert about the boat moving away too much from the point where the achor was dropped.

Best for anchorage task. Different from other similar apps is that you can set it up after an anchor ⚓ is out. Allows to adjust anchor bearing, distance, danger sector, etc. I used it since 3 years and it works well. Minus one star

It seems like an awesome app but on my galaxy s5 I can't access the options screen like I can on my tablet. Even on the paid version.

Used to require internet access frequently to check license now only the first time and every eight months after. Thanks for fixing this. I like the app and sleep better with out on.

A great alarm for when you're on the boat. The emergency call option is a good idea, but it doesn't link well with hangouts or Skype. I can't get it to make calls over data from my tablet. It opens the app but doesn't automatically make the call.

Good App. Needs several choices for alarms. Siren gives you a heart attack. Also needs a button to push when you drop your anchor so you don't have to estimate it's location later. Like being able to set a swing range.

Would love an option to keep the screen on while running.. Along with a night mode. And a track display of where you've been. Then it would be perfect.

After spending a night watching that the boat hold position on a stormy night, it finally dragged anchor. This would have helped. Would be nice if it used Open Street Maps because there often is no network connection. Also would prefer the defined zone to be a straight line (instead of an arc and a circle) as that better describes most shores.

the app is good but it uses an ordinary land map not sea charts. l can't find the exact position on a map... the sea is all blue, no contours or depth. As such I feel it is only half as good as it could be. I shall use it until I find one with charts not maps.
