New in 2.1: see your dog's track from a GPS collar over the track you laid. Article search, area search, night mode, blood tracking and spoken alerts. Trax is a GPS logbook for tracking dog training. First, the track layer walks the route and drops items along the way. Trax records the track and marks every item on the map. Later, the dog follows the scent trail with its handler, and Trax records that too. When you are done, you see the laid track and the dog's route together on one map, with track age, distance, finds and the weather. LAY A TRACK • Record the route with GPS while you walk • Tap Marker to drop an item at your exact position • Choose the track type: track, IGP track, blood track or search • Lay cross tracks: a fresher track that crosses the main track • Add notes about terrain, conditions or anything else you want to remember RUN THE TRACK • Choose the dog when you start, so every session is saved to the right dog • See the countdown until the track has the right age, also on the Lock Screen • Get an alert near an item or a crossing track, and when you lose the track • Spoken alerts in AirPods or the speaker, even with the screen locked • Lock the screen and keep the phone in your pocket: a Live Activity on the Lock Screen and in the Dynamic Island shows the track and has Pause and Found buttons • Walk blind: the laid track and the items stay hidden until you stop • Night mode with red light, so you keep your night vision • Standard map, topo or satellite SEARCH • Article search and area search: draw the field or area on the map, or pick a ready-made size • Place items and people, and see the time to each find • Optional time limit with an alert when one minute is left BLOOD TRACKING • Shot site, flight direction, wound bed, blood stop and game • Amount of blood, tracking shoe or hoof, and track age up to 48 hours • Turns in the track are counted automatically SEE THE RESULT • Both routes on one map, with found and missed items • Play back the track and watch the dog's route over the laid track • Deviation from track: see how closely the dog followed it • Track age, distance, time, wind and weather for every session • Give a rating, difficulty and learning point after every track • Filter completed tracks by dog and follow progress over time • Trim the start or the end of a track YOUR DOG'S TRACK FROM A GPS COLLAR • Does your dog wear a GPS collar, such as Garmin or Tractive? Add the GPX file from the collar to a finished track • See the dog's actual route over the laid track and your own route • Playback shows the dog and you as two dots, with the distance between you • Trax finds the right track from the time, and asks which dog if the file has several SHARE AND EXPORT • Share your track on social media, laid over your own photo or on a map, with many layouts and colors • Send a track to another Trax user, for example when one person lays the track and another runs it • The track layer does not need an iPhone: lay the track in any GPS app that saves GPX, with waypoints for the items, and run it in Trax • Export to PDF, per track or as a report per dog • Export and import GPX files LANGUAGE Trax is available in English, Norwegian, Swedish and German, and follows the language on your iPhone. PRIVATE BY DESIGN No account, no login and no ads. Your tracks are stored on your iPhone, with a backup in your own iCloud Drive. GPS is used only while you are recording. Made for handlers, instructors and anyone who trains tracking, whether for fun or for competition.
