Delta vs RaceChrono
Choose Delta when your AiM is already the logger and you want the shortest path to private iPhone review. Choose RaceChrono Pro when the phone is part of the logging system or you need external GPS and OBD support, synchronized video, GoPro control, configurable overlays, and broad export formats.

Delta starts with the AiM
Delta assumes the logger has already recorded the authoritative session. Its job begins when you return to the paddock and want that session on the iPhone.
RaceChrono can be the logger
RaceChrono is a full lap timer, logger, and analysis app. Its published feature set includes external GPS receivers, Bluetooth and Wi-Fi OBD-II readers, video recording, action-camera synchronization, and overlay export.
Choose around video
If video capture and rendered overlays are required on the phone, RaceChrono Pro is much broader. If video is irrelevant between sessions, Delta’s narrower interface avoids that setup.
Choose around your source of truth
Use Delta when the AiM device is the source of truth. Use RaceChrono when you want the phone and connected receivers to create or augment the session.
FAQ
Does Delta record laps with the iPhone GPS?
No. Delta reviews sessions recorded by compatible AiM hardware.
Can RaceChrono create video overlays?
Yes. RaceChrono Pro publishes configurable video overlays, multi-camera recording, and action-camera synchronization.
Which app is simpler for an existing Solo 2 owner?
Delta is narrower and purpose-built for direct AiM review. RaceChrono is more capable when you also need recording hardware, OBD, video, or export workflows.
