Hotlap vs LapTAR

Experience the competitive spirit and camaraderie of track days from anywhere. Hotlap is an exciting new community for track day enthusiasts. With intuitive GPS lap timing and data logging you can ealiy compare your performance with fellow drivers to achieve your next personal best.

LapTAR turns your phone into a lap timer that coaches. It times every lap on GPS, shows the live gap to your own fastest possible lap, and tells you which corner — and which part of that corner — cost the time. TIME EVERY LAP Pair a RaceBox or Dragy GPS receiver over Bluetooth and drive. The track is recognised from where you are, the start/finish line is already drawn for the circuits in the library, and you can draw your own for a kart track or a hillclimb. THE GAP THAT MATTERS The delta on screen is not to your best lap. It is to your optimal lap — a physics simulation of what your car has proven it can do, on the best lines you have driven — so you are always chasing a time within your reach. CORNER BY CORNER Every corner is scored in four phases — braking, entry, apex and exit — against that optimal. Lights show where you gained and where you lost; the numbers sit underneath for later. A CO-DRIVER IN YOUR EAR At the line the voice calls the lap: a new best, or how far off. Pick a corner on the session's list and it is called through on every lap — "Next right. On my call." then brake, turn, power, full throttle, each word timed to land on your optimal lap's own point, the brake call earlier when you arrive faster. The corners you leave to the coach get the fix before — "Next left. Brake 30 metres later" — and better, worse or the same after. One to four corners a lap, your choice. When a corner goes wrong it says “Missed” at once and leaves the rest to you. Nothing to read at speed. ANALYSE IN THE PADDOCK Speed, delta and g traces per corner, laps drawn over the track on satellite imagery, and trends across sessions. Log the surface and your setup sheet with every session; the tyres and alignment the car was on that day stay with it, so a change in the garage never rewrites an old lap. VIDEO OVERLAY Export a lap as a data overlay — lap time, delta, speed, corner lights — ready to drop onto your camera footage in CapCut, DaVinci Resolve or Premiere. ENGINE DATA Add a Bluetooth LE OBD adapter for RPM, throttle and more, recorded alongside the GPS. Practising at home? LapTAR also takes Assetto Corsa telemetry straight from the game. FREE, AND LAPTAR PRO Your first track day is on Pro: everything on, all day. After that, Free records the first ten minutes of each session, or the first five timed laps when those take longer — counted down on the live screen, with the coach on one corner a lap; the session is kept like any other. Importing from other apps is free with no limit. LapTAR Pro, an optional in-app purchase (monthly or lifetime), records the whole session, every session; remembers the track (your best ever lap as the live reference, trends across sessions, earlier setups, laps from other days to compare); coaches up to four corners a lap and calls the corners you choose through; and adds clean, transparent and 4K overlays, advanced OBD (custom PIDs and alerts) and export to other apps' formats. A free account is required — just an email and a password. It is the same account as on timeattack.run. LapTAR Pro Monthly is an auto-renewing subscription: it renews each month until cancelled, and can be cancelled any time in your App Store account settings at least 24 hours before the period ends. LapTAR Pro Lifetime is paid once. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://timeattack.run/privacy
