TaxBird is an Android application developed by ware2now that allows you to track your tax residency easily. This application supports country-level tracking worldwide, state-level tracking in the US, and province-level tracking in Canada. It provides real-time tracking in the background that runs using your phone's location services, showing how many days you've spent in each location, and how many days you have left before reaching a residency threshold.

With TaxBird, you can not only track your residency, but also receive automatic notifications when you approach a residency threshold, and generate comprehensive reports to support your residency status for tax purposes. The application also includes plans for projected counts, making it easier for you to plan your residency.

The application is free to download and offers a 30-day trial before subscribing. After the trial, you can subscribe to TaxBird for an annual fee of $34.99, which will be charged directly to your Google Play account. The subscription will automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. The user can manage the subscriptions and turn off auto-renewal by going to the Account Settings. No cancellation of the current subscription is allowed during the active subscription period.
