Read full description
Where am I losing time? That is the question between runs, and IRA answers it before your helmet is off. Import a session and IRA compares every lap with your best: lap times, split times (Split 1–3), your theoretical best lap built from your best splits, and how much time is still on the table. Real telemetry, laid out clearly, so you know what to work on in the next run. YOU drive, IRA analyse. Built for kart drivers, track-day and circuit drivers, teams and racing families. FOUR WAYS TO GET YOUR DATA IN - From a file: copy it off the memory card or the device app, then pick it in IRA. - Over Wi-Fi: AiM MyChron 5 / 5S / 6 / 6 2T, AiM SOLO 2 / SOLO 2 DL and UniPro. Join the device's Wi-Fi and your sessions come across without a cable. - Over Bluetooth: pair a RaceBox Mini, Mini S or Micro once, then read the laps it recorded or follow a run live. - With your phone: record route and speed with your phone's GPS. No logger needed to start. Lap timing is not part of phone recording yet. SUPPORTED DEVICES - AiM MyChron 5 / 5S / 6 / 6 2T - AiM SOLO / SOLO 2 DL - Alfano 6 / 7 - UniPro - RaceBox Mini / Mini S / Micro - RaceChrono - Phone GPS WHERE I LOSE TIME Open any session to see every lap against your best, your split times, your fastest and slowest laps and your theoretical best lap. Switch to charts for speed, RPM, water temperature and EGT, or replay the lap. LAP REPLAY Replay a lap on the real track outline with three camera views (top-down, follow and drone), playback speed control and a lap picker that switches laps without leaving the player. SESSIONS CALENDAR Every session on a month calendar or in a list, with best lap and lap count at a glance. 5,000+ TRACKS IN 111 COUNTRIES Automatic GPS track detection, track details, and a 7-day forecast with tyre advice for race day. GARAGE Keep track of your racing expenses and your inventory: which parts are fitted to which kart, and what is worn out. PIT NOTES A checklist before and after each run: conditions and track, cold tyres, engine and drive, carburettor, chassis front and rear, hot tyre measurements, weight and notes. Copy the previous run and change only what differs, so you can always look back at what you ran. FAMILY FOLLOW A parent or team member can follow a driver's sessions, with the driver's approval, and see the same numbers the driver sees. 35 LANGUAGES The app is available in 35 languages.
