Sim Racing Telemetry vs iSpeed
Quick summary
Verified pricing differs — Sim Racing Telemetry: Free + per-game DLC · iSpeed: Free (donationware).
Verdict
Which one should you pick?
Choose Sim Racing Telemetry when you want telemetry from console titles — it has a verified free tier.
Worth knowing: Records only complete timed laps, capture device and game machine must be on the same network, and per-game DLC bought on Steam is not transferable to the iOS/Android versions
Choose iSpeed when you want community lap data on iRacing — it has a verified free tier.
Worth knowing: iRacing-only and visibly dated — the official site still lists compatibility as Windows XP through Windows 8, and unlicensed copies show periodic donation prompts
