Tax Days vs. TaxBird
TaxBird pioneered the snowbird-tracking category for individuals. Tax Days takes the same problem and adds international rules (Schengen, UK SRT, 30+ countries), drops GPS, and cuts the price. Here's a head-to-head.

Which one is right for you?
Tax Days is best for…
- iPhone users who want privacy by design.
- Anyone with international travel patterns.
- Anyone who wants 0% data on a vendor's server.
- People who'd rather pay $20/year than $60.
TaxBird is best for…
- Android users (Tax Days is iPhone-only).
- Pure-domestic US snowbirds with no international travel.
- Anyone who wants background GPS automation.
- Anyone who needs a web dashboard.
Bottom line: If you're an international traveler — even occasionally — Tax Days is the only one of the two that runs the 90/180 Schengen calculation, the UK SRT, and 30+ international rules. For Android users on a US-only itinerary, TaxBird is a credible choice.
