More infos at gps-tracker-tool.de (support url). WHAT IT'S NOT - You can NOT track other phones with this app! This is a "remote control" for one of the dedicated hardware GPS trackers from the list of compatible models. - You cannot send SMS from iPod/iPad devices. However, you can still use the LIVE tracking features. MAJOR FEATURES - app will draft SMS commands for you - no need to carry around the tracker's manual - built-in compass for off-road navigation to tracker location - offers cell triangulation as fallback - reverse geocoding - administration of multiple trackers - visual set-up of geo-fence - configurable unit system (mi, km/h – m, ft) - quick commands = easy accessible custom commands - in-app purchases to enable the LIVE tracking features for some models: Trip history, trip start & end alerts, speed alert, geo fences, KML export INCOMING SMS You just copy the whole incoming SMS and switch to the app. It will then try to match it against known formats. All data can then usually be visualized on the map. Please understand that iOS DOES NOT ALLOW to intercept incoming SMS automatically! Some tracker models can be monitored via the internet. SUPPORTED TRACKER MODELS Anywhere (TK 108), Asta (EV07S*), ELRO (GPS1), Concox (GT02, GT011, GT 100), Incutex (TK 5000*, TK 104, TK 105*, TK 106, TK 116), meitrack (VT 310 v6, VT 310 v7), PAJ* (Allround, Easy, Gold, Motorcycle, Mini, Personal, Power, Professional), Simvalley (GT 60, GT 170, GT 280), TKstar* (Bike, 720, 816 OBD, 901, 905, 909, 915), Toplovo (TL 202), Wonde Proud (SPT 10, VT 10), Xexun* (TK 101, TK 102, TK 102-2, TK 102v6, TK 103, TK 103-2, TK 104, TK 106, TK 201, TK 201-2, TK 202, TK 203, TK 206, XT 009) * InApp live tracking via Internet for these models possible. After you made the tracker connect to the server, the feature can be activated with an InApp purchase. Model names might not always be unique amongst manufacturers, so if your tracker came with a manual, you can check for compatibility here: https://gps-tracker-tool.de/compatibility/ (see also support-url) KNOWN PROBLEMS - Please note that while you can send iMessages, you cannot send SMS from an iPad or iPod and therefore you would have very limited functionality on these devices. Still, an iPad would be a good choice for the LIVE tracking part. - Since iOS 10, short messages which contain links will be broken up into two. This makes copying a whole message impossible. You might have to miss out on the app's ability to visualize an incoming message from certain trackers. (If you experience any problem or have a feature request, please send us an e-mail. You find the address in the app's help section.)

Introducing Pilot's Altimeter: The best app for aviators seeking an altimeter that works just like in a real aircraft; harnessing the power of your Apple Watch's barometer and classic dial display to give you an authentic experience. Whether you are a novice pilot or a seasoned pro, make Pilot's Altimeter your go-to training tool or wrist companion. Student pilots can gain a deeper understanding of traditional pressure altimeters before taking flight. To Use: Set the current pressure setting at your location in the Kollsman Window using the digital crown. This can be found by looking up the METAR at your closest airport or if you know your current elevation you can set that altitude on the dial. As a last resort you can get your GPS altitude from your phone or watch and set this on the dial. Once the altimeter is set to the local pressure, the dial will update to display your current altitude as it changes. Changes in weather throughout the day or traveling a large distance will change the local pressure so be sure to update the setting frequently to get the most accurate results. Updates to the barometer data can be delayed in certain conditions. Pilot's Altimeter has implemented an escalating warning system to notify you of stale barometer readings: - Yellow BARO Warning: The barometer data is older than 5 seconds. - Orange BARO Warning: The barometer data is older than 15 seconds. - Red BARO Warning: The barometer data is older than 30 seconds. - Red Flashing BARO Warning: The barometer data is older than 60 seconds. - Anytime the barometer data is more than 15 seconds, the seconds will be shown in the upper right. Accuracy Disclaimer: The barometers in your Apple Watch are highly accurate but are not calibrated to the standards of the altimeters found in real aircraft. Additionally, due to how the Apple Watch provides this data to applications there can be a delay between readings. Lastly, being an electronic device with very small sensors there are more failure modes than analog altimeters. Pilot's Altimeter makes every effort to make it clear to the user how reliable the data being displayed is, however it is no substitute for real instruments and should not be used as a primary or even secondary flight device. THE USER ASSUMES ALL RISK FROM USE OF THIS APPLICATION IN AN AIRCRAFT
