Location generally recorded throughout the day using the highest level of accuracy supported by your phone (consistent with efficient battery usage). Location is determined using a combination of GPS, Bluetooth, Wi-Fi hotspots and cell tower locations and then recorded. Please note that the continuous tracking may have a minor impact on battery life and data usage since location is continuously recorded and saved in the cloud. The App's applicable location algorithms are designed to minimize battery use.
Separate tools to check (a) Schengen Region status, (b) U.S. substantial presence test, (c) rolling 183 out of 365 day check, (d) Puerto Rico day count testing and (e) U.K. statutory residency test using the U.K. April 6 through April 5 tax year.
Tools also provided to check location day counts considering only overnight stays or 24 hour periods (for UK, Monaco, Maryland, New Mexico, and other similar jurisdictions).
Audit Defense
Tax jurisdictions are increasingly aggressive in asserting residency — subpoenaing phone records, cell tower data, credit card logs and other items. The burden of proof is on you. Domicile365 generates a cryptographically-signed, contemporaneous record of your physical presence — and now lets you produce a signed PDF that auditors, courts, or opposing counsel can independently verify on Domicile365.com, confirming that your location logs are authentic and have not been altered after the fact.

The app seems to work well. I had an issue with the total day count not being correct. Their customer support replied back in a few days and resolved the problem.Just note if you're traveling that the day counts per state will be more than your total time because of partial days.
Developer Response
We have reviewed your logs and they are in order. What happens is if you travel and are in multiple states on the same day, your aggregate state count is going to be higher than your country day count; each visit to a state counts so if you travel through 3 states on a day, you will register 1 day in the U.S. but 3 state day counts. Please reach out to customer service (support@domicile365.com) if you ever have questions on these issues.
Back on track and loving this app

Buggy, slow, and awful interface.
MC_slo
One of the most poorly designed programs I’ve used in years. There is NO graphical user interface; just a few colored buttons. After entering two months worth of data in about two hours using drop down calendars that ALWAYS default to todays date, the ONLY way to see what I had done and still needed to do, was to export a spreadsheet and go through it day by day and line by line. NOT a good program.
Kinda blown away
Mes..
This app just works as described … but what blew me away was the custom service when I had a question. Responsive, complete, and understanding. Lastly this is my first ever app review, that’s how good this has worked.
We are always working to improve the user experience through new features and product enhancements. It is important to us to invest in adding features and making the app run smoothly and error free.
This version makes minor bug fixes and adds some user interface improvements.
