Approach Alarm

Never miss the lap that matters.

Timing multiple drivers is normally easy to miss a lap. The Approach Alarm pulses your iPhone the moment any driver is closing to finish the lap, so your eyes are already up when they cross the line.

Strength tunes from Light to Strong so you feel it through racing gloves
1 to 5 pulses — short tap for veterans, sustained buzz for distracted pits
Reference Best Lap (qualifying) or Previous Lap (race-pace tracking)
Threshold in milliseconds: fire half a second early, or right at the line

Up to 8 Stopwatches

Time your whole grid, all at once.

Coaches used to manage four hardware stopwatches with rubber bands, sticky notes, and prayer. BestLap Pro runs eight — independently controlled, millisecond-precise — on a single iPhone. The layout adapts: focus on one driver in the four-up view, or scan the whole field in the eight-up compact view.

TouchDown capture — the lap fires the instant your finger touches the screen, not on lift-off
Unlimited mid-lap splits with sector-accurate timing
Live deltas vs. each driver's personal best, color-coded purple (session best) and green (PB)
Glove-friendly hit zones, high-contrast dark mode for bright sunlight

Session Analysis

Every lap. Every split. Every session.

The second a session ends, BestLap surfaces what coaches actually need: best lap, average, total laps, and a real consistency metric (standard deviation, σ) per driver. Every lap is tagged with its splits and color-coded against personal best and session best. Pull up any past session by championship, driver, or date.

Per-driver consistency in σ — the number engineers actually quote
PDF and CSV exports via the iOS share sheet — email, AirDrop, or cloud
Full archive searchable by championship, session, driver
100% offline storage — sessions persist even in airplane mode

Built for the track

Engineered for race-day reality.

BestLap was built in the paddock, not the office. Every detail exists because someone needed it trackside.

Race-day reports

PDF reports your team will actually read.

Per-driver summary, full lap chart with purple-best and green-PB color coding, ready for the engineer's email or printed at the trackside cafe.

Tunable haptics

Felt through gloves, not over engines.

Strength, pulse count, and alarm reference all adjustable. Test the vibration without leaving Settings — tune it to your kart's idle and your gloves' thickness.

Live timing

Every running lap, every running delta.

Live delta vs. personal best on every cell. Last lap pinned to the right. Mini lap strip across the bottom. The session-best banner at the top. Everything you used to chase across a paper notepad — in one glance.

Searchable archive

Find any lap, any session, any time.

Filter by championship, session name, or driver. Every session you've ever recorded, with full splits and consistency intact — even sessions from a track with no signal.
