Would you enjoy spending time on your boat and not have to worry more about your anchor?
The anchor watch monitors the position of your boat and sounds an alarm if your boat is out of the anchor radius.
Enjoy the time on board or get to sleep while the anchor watch pays attention to your position.
- Supervision of the boats current GPS position
- Adjustable length of anchor chain
- Adjustable monitoring sector
- Adjustable GPS update cycle
- GPS signal monitoring
- Battery monitor
(c) 2012, Torsten Schumacher & Oliver Klug (UI design)
- Satellite Map display of anchor and boat position.
- Raises an alarm even if the application is not running in the foreground.
- Display of a red/green icon for easy alarm recognision
Start the App before arrival at the anchorage and check for obstacles on the satellite map. Tap the blue marker the moment zou drop the anchor and select "Move Anchor" for set the position of your anchor. After enough chain went out and the anchor is set, tap the blue marker again and select "Set Alarm Distance" to set the alarm distace. Make any necessary corrections to position and distance before aktivationg the alarm Sound.
The distance drifted and bearing to the set anchor point are shown.
There are two views, the default test view and a map view which will show the anchor point and the drift track which will be in green if the boat is withing the set scope and red if outside.
There are settings options to enable you to choose whether to use feet or metres and whether to allow the app to run in the background etc
In addition to the alarm you can elect to have an SMS message sent if the boat drifts outside of the set scope. Only one SMS will be sent. If you reset the anchor position then another SMS will be sent of the boat drifts outside of the new scope.
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 sector in that area 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.
- Run in the background, which is safer and save battery power.
- Main screen shows useful information:
1. Current position (latitude, longitude and accuracy of the measure).
2. Current security radius.
3. Current drift.
- Graphically and easily set a security zone with optional exclusion sector. (The exclusion sector is only allowed in pro version).
- Wind forecast included (48h). You will be warned if the boat is going 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.
- Access the main menu from the notification bar once the alarm is set (easy access).
- Once the alarm has been 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 call a phone number when the alarm is triggered.
- Remote commands (only pro):
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 one minute without GPS signal, the alarm is triggered. It is assumed that the device has no GPS signal.
- 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 (Only pro version).
3. Continuous. GPS readings every 1 second. Same algorithm as in fine mode. Optimus for adverse weather conditions. More power consumption (Only pro version).
- 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.
- If alarm is not set, you could use the map window as a navigation assistant (e.g. when it is foggy). Keep in mind that the device does not act as a radar and can not detect other boats. Use it at your own risk.

Niente di piu' niente di meno che un'app con cui consultare le previsioni del vento in superficie con modello ALADIN, disponibili a http://meteo.arso.gov.si/met/en/.
Fatta da un kiter (non un granché a dire il vero) per i surfisti! L'app vuole essere veloce, senza fronzoli ma utile: nessuno vuole vedere mille animazioni bellissime quando deve decidere se caricare l'auto con tavola e vele / ali e partire per la spiaggia.
Se non sei un surfista l'app non ti serve, scaricarla sarebbe una perdita di tempo.
L'app e' gratuita, ha della pubblicita' che appare mentre sta scaricando le carte del vento. Il download delle carte prosegue anche seguendo il link pubblicitario, quindi non vi fa perdere un solo secondo!
Si tratta di un'app molto semplice e, di sicuro, non è esente da bug. Invito chiunque voglia contribuire con suggerimenti, segnalazione problemi, etc. a mandarmi una mail.
The app also supports promotion code discounts with a deals section, course information and an account page to look up past reservations and share these reservations with your playing partners via text and email.
Visualize navigation data on your phone or tablet: position, SOG, COG, speed, heading, apparent wind, true wind, ground wind, VMG, Beaufort force, depth, water temperature, UTC time. (A NMEA 2000® or a NMEA 0183 WiFi adaptor is required to receive NMEA data. SeaWi decodes NMEA 2000® and NMEA 0183 data received in TPC, UDP Unicast and Multicast packets).
You can also use the built-in GPS of your device to show position, SOG, COG and UTC time.
SeaWi decodes AIS information and allows you to visualize AIS target information on your phone or tablet: AIS target name and MMSI, AIS target position, AIS target SOG, AIS target COG, distance and bearing from your vessel, heading, rate of turn, length, beam, draft, IMO, Callsign. SeaWi shows AIS targets on the chart and triggers alarms for dangerous AIS targets or AIS target lost. (An AIS receiver and a NMEA 2000® or a 38400 baud NMEA 0183 WiFi adaptor; or a WiFi AIS receiver is required to receive AIS info).
You can select your buddies and keep track of them.
SeaWi allows you to program multiple alarms: anchor alarms, depth alarms (shallow water alarm, deep water alarm), alarm of lost data (depth data lost, heading data lost, position data lost, apparent wind data lost) and AIS alarms (dangerous AIS target, lost AIS target).
You can create a track tapping the Create new track button from the Track View. The tracks are saved and may be visualized at any time.
You may configure the time period or the distance between track point creation and the number of viewed points at high resolution.
You may continue a saved track whenever you need it.
You can create a waypoint tapping and holding on a chart position. Once the waypoint dialog appears you can modify the waypoint position and place the waypoint at your vessel’s position or at a position of your choosing. You can mark the waypoint with six different symbols: generic waypoint, anchorage waypoint, diving waypoint, fishing waypoint, dangerous waypoint and MOB waypoint. You may add a photo to your preferred waypoints.
Man Over Board (MOB)
You can create a Man Over Board waypoint with only one click (menu MOB). Your vessel's position and UTC time and date will be automatically saved. You can manage the MOB mark as a waypoint from waypoints view.
The SMS Service allows you to receive SMS messages when an alarm is activated. If you are anchored and you are not on board you can program alarms (anchor alarm, depth alarm, dangerous AIS target alarm or lost data alarm) and receive them on your phone. When not on board you can schedule SMS messages at certain intervals of time and receive navigational data from your vessel on your phone.
SeaWi NMEA forwarding
You can forward all navigation and AIS data where you need them. Forward NMEA data to other tablets and phones on your boat. Forward NMEA data remotely and use SeaWi app to visualize the same navigational and AIS data as if you where aboard.
Log Trip and Simulation Mode
You can record navigational data of your trip and recover them later to review your trip in Simulation Mode.
Off-line OpenSeaMaps charts of the entire world are available. Currently charts of Europe, North America, Mediterranean Sea, Black Sea, Caribbean, Australia, New Zealand, Pacific and North Africa are available. Charts of the rest of the world will be available soon.
OpenSeaMap is an open source, worldwide project to create a free nautical chart. In 2009, OpenSeaMap came into life. This map includes beacons, buoys and other navigation aids. OpenSeaMap is a subproject of OpenStreetMap and uses its database.
Continued use of GPS running in the background can dramatically decrease battery life. The use of the inboard battery or an external battery is recommended
Please note that this application still in a beta verson.
This applications helps sailors to keep their logbook accurate and up-to-date. Different trips can be managed by this application. The route can be shown on the map and detailed log can be maintained. The device's sensors are used to fill as much as possible automatically.
First you need to create a trip. As soon as a trip is created the application will automatically track your sailing route in a configurable interval. This functionality can be paused and resumed any time.
For detailed log you should add log entries manually. In manual log entries you can fill out details, e.g., weather conditions, sea, sky, engine state. For faster and more detailed log there are some shortcuts available in the home screen where a weather change or engine on and off switches can be logged. This will create a partial log entry keeping your logbook detailed.

CarpeTempus will accept any number of alarms (particular time of day, and day of week, month, year, etc.) or timers (durations in seconds. minutes. hours, etc.).
When it's time for CarpeTempus to alert you, it will speak the message you choose, or play an alarm ringtone, or play a piece of music you choose.
The CarpeTempus alarm scheduler is very sophisticated — you can choose a time of day, one or more days of the week, one or more days of the month, or a particular day of the year — or any combination of these.
CarpeTempus timers are much like alarms, except they're meant for time durations, not times of day. You can set time durations from one second to 100 hours. When the time arrives, all the features of the alarm scheduler are available — spoken messages, ringtones or user-selected music.
Once you have programmed some alarms and timers, you can put your Android device in standby mode. Then, when it's time for an alarm, the CarpeTempus service daemon will wake up, turn on the display, and alert you.
It's not necessary to type reminder messages. To program a CarpeTempus message, you can speak the message instead of typing it.
CarpeTempus is free and open-source, and is licensed under the GPL.
One more thing — CarpeTempus has no ads, no tricks and no strings attached. CarpeTempus is exactly what it appears to be — a nice, free application.
