On supported roads, Tempo adds average speed check assistance to the navigation you already use. It is not a map and replaces nothing: it runs quietly in the background alongside Google Maps, Apple Maps or your car's built-in navigation. ON A SECTION, THE AVERAGE IS WHAT COUNTS Average speed cameras do not measure your momentary speed - they measure the average over the whole section. Tempo measures it the same way: it detects the entry, anchors the measurement at the gantry and shows your average since entry, the recorded limit and the distance left, with a progress bar and an honest uncertain state when the GPS signal is weak. A VOICE THAT DOES NOT GET IN THE WAY Critical above-limit warnings stay available to every driver. Tempo Pro adds the full spoken profile for approaching a section, entry, progress and completion. Prompts duck your music and hand it back. No chatter, no voice ads. EVERY SURFACE - Native CarPlay section and time/risk screens - Live Activity and critical alerts on the iPhone lock screen - Apple Watch: average, limit and distance on your wrist, with gentle haptics - Lock screen widget BETWEEN SECTIONS The screen shows your GPS speed and a simple meter: how many minutes going faster actually buys, and how quickly the population-level modeled road-injury risk trend grows. Facts, no judgement. Plus the distance to the nearest measured section. DATA YOU CAN TRUST The section and camera database is built exclusively from official public data, with a public changelog and a verification counter. Data updates arrive without an app update. PRIVACY WITHOUT AN ASTERISK No account. No ads. Your routes never leave the phone - App Privacy: Data Not Collected. TEMPO PRO Automatic start, the recorded limit, section progress, critical above-limit warnings and the phone time/risk meter stay free. Tempo Pro unlocks the numerical live section average, the full voice profile, the full native CarPlay views and the Apple Watch average. Monthly and annual plans are available; trial terms are shown before purchase. The subscription follows your Apple Account on supported devices and can be managed in Apple's subscription settings. Tempo informs about official speed enforcement infrastructure and guarantees nothing. Road signs and regulations always apply. GPS measurement may differ from the gantry system's measurement.
