I would suggest to pick a name that have ".com" domain available for it. The only name from your list that match this criteria is "paktrack" (the price is pretty high though).
Thank you Keymaster we also have .pk domain :)
Regional domain is good, but you need to think about future opportunities. It's always good to have a ".com" domain if you want to go global.
our target is local market only
Then "youtrack" and "safestack" I think sound better. I would add GPS somewhere in the domain.
If you want expert suggestion for use of unique brand and business name, try this one http://eatmywords.com/services/taglines/, it is also the same resources that I used.
youtrack
wetrack
ontrack
paktrack
safetrack
axestrack
mytrack
