The walks on your phone are sorted “closest starting point first”, so the walk you want to do is probably on top of the list. Just tap it to go the the walk screen.
Some theory first
This theory applies to both Watch as iOS app. If you start a walk, you’ll see up to 5 arrows
- A red one : the trackpoint you just passed
- A green one : the next point
- Up to 3 purple ones. 3 points next on your way.
And you have a blue dot with 2 arrows attached to it – called navigationArrow :
And finally, there are 2 theoretical concepts you should know about
- GPS postition : thats where the GPS-chip in your phone or watch thinks you are.
- Theoretical position : this one is derived from the GPS postion, from the distance you walked and from the track you should follow. This postion is where TrackGuide thinks you are. The theoretical postion is always on track. GPS postion might be (far) off, depending on the quality of GPS reception.
On your watch, the navigationArrow is drawn on your GPS postion while the theoretical postion is visualized by a green dot.
On your phone, the navigation arrow is drawn on your theoretical postion, while the GPS position is shown by the standard blue pulsing circle from Apple maps.
This is how your watch looks whilte guiding you:
And below (after the heading) is how the phone looks at exactly (more or less) the same spot.
Note that, while the watch always shows the north on top, the phone maps rotates with your direction (you can turn this off if you wish). On both screens, we are walking in the right direction (green arrow points up – blue arrow points to the next point). And on both screens, the GPS chips think we are walking through the buildings at our right.
The walk screen
This screen shows two maps : the upper map will guide you (it will be called ‘navigation map’ in the rest of this post) , the lower one (called ‘overview map’) gives an overview of the complete walk. Both maps show your current position – the upper map always, the lower map only if you are close enough. The overview map cannot be zoomed, panned or rotated – it is fixed to show you your complete walk. The upper map can freely be zoomed, panned, rotated etc until you press the “start” button. When pushed, TrackGuide takes over zooming, rotating and panning from you.
You do not need to push the ‘Start” button to be guided – just seeing your position and the red trackline might be enough to stay on track. You can zoom in and out at will to take a closer look at where you are and where you must go to. However, you can automate this guidance a bit by pressing ‘Start’. If you do so, TrackGuide will…
- Add the direction arrow to the map and keep it up to date.
- …manage zooming, panning and rotation of the navigation map for you. It will keep
- the navigation map centered on your current position.
- rotate the map so it is alligned with your heading. If you hold the phone flat in front of you, the road you are walking on will be alligned with that road as it is displayed on the map
- Automatically zoom in or out so your postion and 4 trackpoints (previous, next and 2 points thereafter – the same points as shown by the watch app) fit in the smallest side of the map view.
- …track your progress on the walk, just as the Wath app does (as described in Watch App Guide 2 : Walking , so with green, red and purple arrows).
- … move the slider up whenever you reach the next point. The lower value of that slider gives the distance walked, the upper value the total distance of the walk.
- …tell you how far it is to the next point, plus some information on that point (45 m. to 45 aStreetName) if available. (text on top of the screen).
- …continously send your position to your watch. So owners of a first generation Apple Watch can get directions on their watch this way.
If you leave the map page to go back to the list of walks, the navigation will be stopped and the GPS-chip our your phone (or watch) will go to sleep again.
When you press ‘start’, TrackGuide will assume you want to start at the closest point – which is not necessarily the start. If you want to start from another point – like the start of the walk – just slide the slider until the little green arrow is drawn where you want to start. To fine-tune the selected start point, you can tap the numbers to the left and the right of the slider. This will move the slider one position up or down. These slider changes will be propagated to the Watch app : the ‘next point’ you select on your phone will be set on your watch so your watch will guide you to that point. The reverse is not true. If you rotate the digital crown to select another next point on your watch, the phone app will not be updated.
