Efficiver

Efficiver — Efficient + Driver.

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

Real-time driving feedback that runs entirely on your Android phone. No insurer dashboard. No data leaving your device. 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 exactly where the orange and red markers landed on the map — and what to do differently next time. 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.

Android Auto support
Drive with your phone in your pocket. Efficiver appears on your car's Android Auto screen — tap Drive to start tracking, see your live score, distance, and time on the head unit, tap Stop to save. Voice prompts route through your car's audio.

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

Annual Savings Projection
Set up Wallet Watch with your fuel cost and currency, and Efficiver projects how much you'll save this year by driving efficiently. The number updates as you drive — surfaced on the Insights screen.

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

Smart Forecast with Idle Lever
The Trends screen forecasts where your fuel-efficiency and mileage are heading, and gives you a "cut idle by X%" lever to simulate how reducing idle time would change your score — all computed on-device.

Anomaly Detection
Drives that fall outside your usual pattern get flagged on the Sessions list, so you can spot what went off and why.

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

Smart Calibration (on-device)
Efficiver learns your vehicle on first setup and keeps all processing on your phone — no cloud calls, no model uploads.

Weather at a glance
Current weather and a drive advisory are shown when you start a drive.

ACCESSIBILITY

Efficiver is built accessibility-first:
- TalkBack support across screens
- Scalable / large text sizes
- Reduced-motion friendly
- Color-coded markers also carry a shape or text label
- Spoken lifecycle cues (Drive started, Drive stopped, Drive saved)

PRIVACY

Everything runs on your phone. Drive sessions, scores, and GPS waypoints are stored locally on your device — there is no account, no sign-in, and no cloud sync. Your precise location is sent only momentarily to weather and maps providers (OpenWeather, Google Maps / Routes / Places) to show weather and plan routes; Efficiver does not retain it. No advertising IDs, no third-party analytics, no telemetry. We can't see your drives, and we don't want to.

REQUIREMENTS

Android phone running Android 12 or later. Android Auto-compatible vehicle for in-car drive control (optional).

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