Clarify your residence status?

Trac-King is the perfect tool for individuals ‘counting days’ or ‘nights’ to establish their country of residence. Trac-King is flexible and works for all countries where day counting is a requirement to help establish Expatriate Tax positions.

UK Expats - find it extremely useful for day counting, in-line with the "Statutory Residents Test" (SRT).

Snowbirds and Non US Citizens can use Trac-KingTM to count days for the "Substantial Presence Test”.

No Data Roaming Charges!

Trac-King has developed a new patent pending Geo-location technique, so it doesn’t require traditional mapping files to confirm your location. This means is it can locate your position, worldwide, without data roaming charges. We believe this is very important to global travellers.

Typically location and mapping based Apps require:

Trac-King does not require either!

"Trac-King just works. It can tell which country I'm in and it doesn’t require me to turn on my data roaming to do so."

Always on but without battery loss

Trac-King runs continuously without loss of battery life often associated with Apps that rely on GPS.

It works efficiently in the background of your iPhone using information generated as you move around, so it uses very little processing power and won’t run your battery down.

Just leave it running to track all your days and nights.

"I can just leave Trac-King running and I'll have a detailed record of my UK days at the end of the year, which I can send directly to my accountant"
