Trackbook vs Launchmeter

Trackbook is a trip log that works on its own. Leave the house and Trackbook quietly records every trip in the background. Open it at night and your day is already laid out in order. No Start button. No Stop button. 1. AUTOMATIC RECORDING • Starts when you start moving and keeps going on the Lock Screen and in the background • Filters out drifting and low-quality fixes for cleaner trips • Don't want to record? Tap the status icon to pause for an hour or discard the current segment 2. FIVE ACTIVITY TYPES, DETECTED FOR YOU • Walk, run, ride, drive and hike, recognized with your iPhone's motion sensors • When the type changes, a new segment starts: walk to the car park, then drive home, and you get a "Walk" and a "Drive" • Turn off any type you don't want saved 3. A DIARY, ONE CARD PER DAY • History is a diary, not a feed: where you went, how you got there, how far and how long • Expand a day for a clean timeline, with the time you spent stopped between trips • Optional place names for stops (off by default; looked up with Apple Maps when turned on) • A one-line note when you moved more or less than usual 4. FOOTPRINT MAP • See the month's routes on a map, colored by walk, run, ride, drive and hike • Total distance, active days and time, plus a breakdown by activity and monthly trends 5. DETAILS FOR EVERY TRIP • Running: pace per kilometer, pace curve, personal bests • Hiking: total climb and descent, grade distribution, steepest stretch • Riding and driving: speed zones, stop log, time in traffic • One-tap share card, with the option to hide start and end so home and work stay private 6. APPLE WATCH • Speed, distance, time, altitude and compass right on your wrist • Pause, end or discard the current segment from the watch 7. LIVE ACTIVITIES • Speed, distance and time on the Lock Screen and Dynamic Island during a trip, with pause and end buttons (turn on in Settings; requires iOS 16.2 or later, buttons require iOS 17 or later) 8. YOUR DATA STAYS YOURS • Automatic iCloud saving: each finished trip is saved as a GPX file in your own iCloud Drive, ready to import in one tap after a new phone or reinstall • Import and export standard GPX files and take your tracks anywhere • Tracks are stored only on your device and in your own iCloud

Launchmeter turns your iPhone into a performance meter. Find a safe, open space and measure your car's 0-60 mph time with one tap. ACCELERATION TIMING & SPLITS • 3-second countdown, then timing starts automatically when you pull away • Time several runs at once — 0-30, 0-60 and 0-100 mph — and set your own targets • Every split is compared with your personal best: green when faster, red when slower GPS + MOTION-SENSOR FUSION • Speed fuses GPS with your iPhone's accelerometer and gyroscope: accurate GPS gets more weight, the sensors fill the gaps between fixes • The launch moment is detected by the accelerometer, so the start isn't delayed by GPS updates • Hand shakes and road bumps are filtered out, so readings stay steady EVERYTHING AT A GLANCE • Big three-digit speed and a segmented speed bar • Friction circle for longitudinal and lateral G, plus a live G-force trace • Grade meter — tap to zero • Local temperature, humidity and pressure from Apple Weather, plus your iPhone's barometer RUNS & ROUTES SAVED • Speed and G-force traces, splits and route are saved on your iPhone for every run • Drag across the charts to replay any moment • Routes keep recording with the screen locked LAUNCHMETER PRO (OPTIONAL, ONE-TIME PURCHASE) • Weather-corrected times: air density, density altitude and SAE J1349 correction so runs compare fairly across seasons and altitude • Export CSV data and GPX tracks • Share cards with your splits and speed trace • Multiple cars: log and compare runs per car Everything else stays free forever. PRIVACY Your runs stay on your iPhone and are never uploaded. Location is only used to measure speed, record routes and look up local weather. SAFETY Only test on closed courses or where it's safe and legal. Obey traffic laws and never use your phone while driving. Continuous GPS use during a run increases battery drain. Results depend on GPS signal and phone mounting and are for reference.
