RTM Radar is free, ad-free and independent — built and run by one person.

Everything here — live tracking, alerts, playback, fare search and Journey Studio — is free, with no ads and no data resale. It runs on a server I pay for personally. If it has been useful to you, a contribution helps keep it online and improving.

PayPal's standard fees apply.

Contributions are voluntary gifts, not a purchase — they unlock no features and buy no guarantees, and they aren't tax-deductible. Payments are handled entirely by the provider you choose; RTM Radar never sees or stores your card or account details.

Not able to give? That's completely fine. Sharing RTM Radar or reporting a bug helps just as much.
