User reviews

Don’t trust it

Worked well for about a year. Then ran into problem where it’s stopped syncing mid 2019. Reached out to developer. He responded once saying they’re working on it .. then never responded again. Sent several messages.. Pleading.. asking for a pay version.. was actually relying on the app. Big mistake. Actual Garbage. Find a different one.

Deleted

If you want the data you will need to pay them. That has not been mentioned here but is mentioned on one of the two websites linked to this app. However, on the other website does not even mention this app as one of their products.
I deleted this app.

Double counts days!

This is very disappointing and repetitive attempts to reach developer were unanswered. If you travel from Miami to NY on the afternoon of January 1 and return on January 2, you will be credited with 2 days in Florida and 2 in NY because you were in each state for part of each day. It doesn’t determine where you were at a certain cutoff time, like midnight, and count that as your location for that day. It just counts being in two cities in one day as two days. It is now 9/30, approximately 270 days into the year and this app shows me spending over 330 days in various locations. If you go through the calendar one day at a time, you can see where you were throughout the day and use that information to build your own travel log, but the log built in is misleading, useless and can’t be exported.

5 star useless app (currently)..

The front end that installs on your phone works well. You can see when and where you’ve been based on date or location. It doesn’t seem to draw much battery either.
Unfortunately, the information the phone collects is basically useless for tax and other residency purposes if it can't be translated into some form an auditor or an accountant can use. The site claims that there’s such a back end solution but I’ve yet to find it. A couple of messages to the developers weren’t answered. I have it installed, it’s collecting location data and maybe one day the developer will have a solution that makes the data collected usable.

Zero Customer Service

Do not use this app. For more than a month we have been trying to get an answer to a question we had about getting a printed report from this app. No reply. This app is useless if you can’t download the results.
