While your exact position is not important, GPS location services are used to track your movement. A large area is not needed to try LineWalk. As long as you have a long space of about 40 metres which you can walk up and down, you're good. (This should be great when you're waiting for a bus or train!)
To avoid all confusion:
- This is a single piece of music, not software you can use with your existing music collection.
- GPS is really needed. The app will not work with network location services. (A lot of tablets only have wifi based location services. They will not do!)
- Wide open spaces have the best GPS reception. If in doubt, open up Google Maps and see how well it works. If it has trouble updating your position smootly all the time, LineWalk cannot do a better job. You should move to another location and try again.
Version 4: Small improvement to GPS code might help users with slightly off local time.
Version 3: An engine bugfix that might solve the crash on SIII and Xperia Neo.
Version 2: Please note that some issues are reported with the Samsung SIII. Some phones of this model won't be able to start this app. There's nothing I can do about it. The problem seems to be on the Samsung side.
