The short version

  • Each has a real cost: OpenStreetMap data accuracy varies dramatically by geographic region depending on volunteer coverage; Transit coverage depends entirely on whether the local transit agency publishes a real-time feed, so quality swings sharply between well-funded metro systems and smaller regional operators.
  • They diverge on capability: OpenStreetMap covers Core Functionality, Transit covers Real-time arrivals.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OpenStreetMap

  • Data accuracy varies dramatically by geographic region depending on volunteer coverage
  • No minimum quality standards enforced, making data prone to errors and inconsistencies
  • Data completeness gaps, especially for minor roads and remote areas
  • Bias toward well-mapped regions with high volunteer activity
  • Positional accuracy concerns with only 70-76% of roads within 5-10 meter tolerance
  • Tag criteria not well-defined leading to logical consistency issues

Transit

  • Coverage depends entirely on whether the local transit agency publishes a real-time feed, so quality swings sharply between well-funded metro systems and smaller regional operators.
  • The company earns its revenue by selling agencies a paid analytics product built from rider trip data, which means the free app functions partly as a data-collection layer for a business customer, not only as a public service.
  • In-app fare payment is only available in a limited set of cities, so the headline feature is not something most riders can actually use.
  • Static schedule fallback in low-data cities is only as accurate as the agency last published, and service changes can go unreflected for weeks.
  • The app has no offline routing without a cached area, so it is not reliable for navigation in areas with poor mobile signal.

Answered from the vendors’ own pages

OpenStreetMap: Is OpenStreetMap free to use?

Yes, OpenStreetMap is completely free and open-source under the Open Data Commons license. You can download and use map data for any purpose.

Source
Transit: Does Transit cost anything to use?

No. The rider app is free with no subscription and no ads; the company earns money separately by selling agencies a paid data and communication platform.

OpenStreetMap: How accurate is OpenStreetMap?

OpenStreetMap accuracy varies by region. In well-mapped areas like developed countries, accuracy is generally high. Only 76% of OSM roads aligned within 10 meters of reference roads, with 70% within 5 meters.

Source
Transit: Does it work in every city?

No. Coverage depends on whether the local transit agency publishes a GTFS or GTFS-realtime feed; some smaller markets have static schedules only.

Transit: Can I buy a bus or train ticket in the app?

Only in cities where the local agency has integrated fare payment; elsewhere you still need the agency app or a physical ticket.
