Warning Light ID

52+ dashboard lights identified instantly. Know what's urgent and what can wait.

DTC Code Lookup

Every OBD-II error code with causes, fixes, and cost estimates. Works offline.

AI Chat Assistant

Works Offline

No signal on the side of the highway? No problem. Everything runs on your phone.
