Efficiver

Efficiver — Efficient + Driver.

Save. Drive. Live.
Offline. Anytime. Anywhere.

Real-time driving feedback that runs on your Android phone. No insurer dashboard. No ads. No advertising IDs. Just your drive, scored in real time, every trip.

Efficiver is built for drivers who care about how they drive. The Efficiency Score updates live as you drive, blending speed, acceleration, idle time, gear use, and route choice. Save a session and see where the orange and red markers landed on the map. Better driving means lower fuel use, fewer emissions, and real savings.

WHAT YOU GET

Real-time Efficiency Score
A single live score that reflects how efficient your driving is, second by second. Calibrated to your vehicle on first setup.

Wear OS companion
Start or stop a drive from your wrist and see your live Efficiency Score, acceleration and braking counts, and elapsed time at a glance. Check the drive advisory, temperature and chance of rain before you set off, and mute voice cues from the watch. Add the Efficiver complication to your watch face to keep your last score in view. Requires the Efficiver phone app.

AI-narrated insights, on your phone
Your Year in Driving and Your Patterns can be written by a small AI model that runs entirely on your phone. Efficiver computes every number; the model only puts them into words. The model is an optional one-time download of about 248 MB, and the app works fully without it. Part of Efficiver Pro.

Trends and patterns
Your average efficiency at a glance, patterns that always have something to tell you, and a forecast chart you can drag across to inspect any day.

Interactive drive map
A full-screen Google Maps view that follows you as you drive. Per-waypoint markers (green / orange / red) show where each acceleration or braking event happened, on the live map and the past-trip route card.

Annual savings projection
Set up Wallet Watch with your fuel cost and currency, and Efficiver projects how much you will save this year by driving efficiently.

Year Recap
A shareable card with your year's driving stats — distance, average efficiency, top drives, and savings.

Efficient Route
Pick the route that scores best for efficiency, not just speed. Compare options side by side before you drive.

Voice coaching while you drive
Spoken cues for drive start, stop and save, and coaching as you go. Plays through your car audio over Bluetooth or aux.

Smart Detection (on-device)
Efficiver learns your vehicle on first setup and keeps all processing on your phone.

Join a fleet (invite only)
Drive for an employer that uses Efficiver Fleet? Enter the invite code they give you. While you are on duty, those drives are shared with your fleet; off-duty drives stay on your phone. You choose when you are on duty and can leave at any time.

ACCESSIBILITY

- TalkBack support across screens
- Scalable and large text sizes
- Reduced-motion friendly
- Colour-coded markers also carry a shape or text label
- Spoken lifecycle cues (Drive started, Drive stopped, Drive saved)

PRIVACY

Your drives are recorded and scored on your phone. Sessions, scores and GPS waypoints are stored locally, and there is no account or sign-in. Efficiver runs no cloud sync of its own; if you leave Android's own backup switched on, your drives and settings are backed up to your own Google account, which Efficiver cannot read. Your precise location goes to weather and maps providers (OpenWeather, Google Maps / Routes / Places) only to return that result.

The one exception is fleets: if you join one with an invite code, the drives you record while on duty are uploaded and shared with that fleet. You are told this before joining and must consent. Off-duty drives — and every drive if you never join a fleet — stay on your phone.

No advertising IDs. No third-party analytics.

REQUIREMENTS

Android phone running Android 12 or later. The watch companion requires Wear OS 3 or later, paired to that phone.

Save. Drive. Live. Offline. Anytime. Anywhere.
