Turn every drive into data — and unlike most apps, all of it is yours from the start. Drivers who pay attention to how their car moves understand that a single figure like top speed tells almost nothing on its own. Meaningful performance data requires context: the route, the forces, the events, the timeline. TripRank captures all of it simultaneously on every drive, stores it in full detail, and makes it available without a subscription gate standing between you and what your own phone recorded. The result is an app that works as a serious performance tool from the first drive, and the feature at the centre of that experience is real-time G-force measurement built around a live radar display. EVERY METRIC THAT MATTERS TripRank records top speed, average speed, distance, and duration alongside G-force on both axes — peak and sustained — braking and cornering event counts with severity, elevation profile, moving versus stopped time, and a bump and pothole counter derived from vertical IMU data. After every trip a full report is generated automatically: a GPS route map with a speed heatmap overlay, a scrubbable speed-over-time timeline, Drive Score, Smoothness Score, and any personal records set during that drive. Share cards for Instagram, iMessage, and the standard share sheet are produced without any extra steps. WHAT MAKES TRIPRANK DIFFERENT → Free users see the complete detail of every trip they record — no stats locked behind a paywall, no pressure to upgrade to access data you created → The G-Force Radar renders lateral and longitudinal forces as a live 2D plot at 50Hz, giving you a real-time picture of how the car is loaded through every corner and braking zone → Drive Score and Smoothness Score assess each trip as a composite, so performance is measured beyond raw speed alone → Weekly challenges and ghost-lap mode let you race against time-limited targets and your own recorded best without manufactured urgency or streak mechanics → Sprint timers auto-start on throttle input and cover 0-100 km/h, 0-200 km/h, 0-300 km/h, 60-120 km/h, eighth mile, and quarter mile with trap speed → Pro is offered once, with honest pricing and no spin wheels, countdown timers, or dark patterns of any kind SPRINT TIMERS Sprint Timer Mode removes everything from the interface except the test you have selected and the number that matters. The app listens for throttle input and starts the timer automatically, so your hands stay on the wheel and your eyes stay on the road. Results are compared against your personal record for that run type and placed on the sprint-specific leaderboard the moment the test completes. There is something quietly satisfying about having a precise record of a drive — not a filtered version of it, not a summary produced by someone else's algorithm, but the actual numbers from the actual road. Over time those records accumulate into something more than data. They become a history of how you drove, where you went, and what the car was capable of on a particular day. TripRank is built to preserve that record with accuracy and give it back to you without conditions. SUBSCRIPTION TripRank Pro is available as a weekly, monthly, annual, or lifetime purchase.

Verdict

The call

The clearest difference is in-app purchases: CTD at none against GPS Speedometer's 12. CTD also leads on ads (none vs shown) and iOS requirement (15.6 vs 17.0). GPS Speedometer's advantage is update cadence (every 2 weeks vs every 21 months). On price, review sentiment and device support there is nothing between them.
