## What is Efficiver?

Efficiver — Efficient + Driver.

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

Real-time driving feedback that runs on your iPhone. 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, route choice, and weather. Save a session and see exactly where the orange and red markers landed — and what to do next time.

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.

AI-narrated insights, on-device (NEW in v1.5)
Your Year in Driving and Your Patterns are written by Apple Intelligence, running entirely on your iPhone. Efficiver computes every number; the AI only puts them into words. Nothing leaves your device. Part of Efficiver Pro.

Trends and patterns (NEW in v1.5)
Your average efficiency at a glance, patterns that always have something to tell you, and an efficiency chart you can drag across to inspect any day.

Apple Watch app
Start and stop drives from your wrist, glance at your live score, distance and time mid-drive, and add the complication to your watch face.

Smarter savings
Wallet Watch prices your driving with a physics-based power model across your entire drive history. Every drive is priced under the fuel type you drove it with, so switching vehicles never rewrites your past savings.

Live stats on your Lock Screen
The Live Activity shows your score, distance and mistakes updating live through the drive — on the Lock Screen and Dynamic Island.

CarPlay support
Drive with your phone in your pocket. Tap Drive on your car's screen, see your live score and distance on the head unit, tap Stop to save. Voice prompts play through your car's audio.

Interactive drive map
Full-screen Apple Maps view that follows you as you drive, with markers showing exactly where each acceleration or braking event happened.

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

Hands-free Siri voice control
"Start drive in Efficiver" starts tracking in the background; "Stop drive in Efficiver" saves and speaks your score.

Smart Detection (on-device ML)
Efficiver learns your engine's signature with Apple's machine-learning frameworks — entirely on-device. No cloud calls.

iCloud sync
Sessions and your trained model sync across your devices via your own iCloud account.

Join a fleet (invite only)
Drives for an employer that runs 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 you can leave the fleet at any time.

ACCESSIBILITY

Built accessibility-first:
• Full VoiceOver support across every screen
• Dynamic Type from default through AX5
• Reduce Motion, Reduce Transparency, Bold Text respected
• Differentiate Without Color (every marker has a shape or text label)
• Lifecycle announcements (Drive started, stopped, saved)

PRIVACY

Your drives are recorded and scored on your iPhone. GPS waypoints are stored locally, and on-device intelligence sends nothing off the device. iCloud sync uses your private iCloud database — no shared records, no advertising IDs, no data brokers.

The one exception is fleets: if you join one with an invite code, drives you record while on duty are shared with that fleet so your employer can see them. 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.

REQUIREMENTS

iPhone running iOS 26 or later. AI-narrated insights need an Apple Intelligence-capable device with the feature enabled. Apple Watch, CarPlay and iCloud optional.

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


## Version history (last 5 releases)

### 1.5.2 — 2026-08-24

What's new in v1.5.2

Choose which voice prompts you hear
Voice Settings now has an Announcements section. Gear changes,
mistake coaching and the drive-resume prompt each have their own
switch, so you can quiet one without silencing the rest. Mute still
works as before, for everything at once.

Clearer Auto-Start and Auto-Stop buttons
The two toolbar buttons no longer change shape when you tap them.
Auto-Start stays a play symbol and turns green when it's armed;
Auto-Stop stays a pause symbol and turns red. Before, both swapped
shape and both turned green, which made them hard to tell apart at a
glance.

Thanks for driving with Efficiver.

### 1.5 — 2026-08-03

What's new in v1.5

AI-narrated insights, on your phone
Your Year in Driving and Your Patterns are now written by Apple
Intelligence, running entirely on your iPhone. Efficiver computes the
numbers as always — the AI only puts them into words. Nothing leaves
your device. Settings now has an Assistance screen showing whether
on-device intelligence is active. Part of Efficiver Pro.

A clearer Trends screen
Trends opens with your average efficiency at a glance, and Your
Patterns now always has something to tell you — it no longer waits on
a forecast. The efficiency chart is easier to read and to explore:
drag across it to inspect any day, and the page still scrolls
normally. Refreshing keeps your chart on screen instead of blanking it.

Auto-Start that tells you the truth
Auto-Start can only detect drives in the background when Location is
set to "Always". Efficiver now checks that properly and walks you to
the setting when it's missing, instead of switching on a feature that
couldn't actually run.

Join a fleet, if your employer uses one
Settings now has "Join a fleet" for drivers whose employer runs
Efficiver Fleet — enter the invite code they give you. Only the drives
you record while on duty are shared with your fleet; off-duty drives
stay on your phone, and so does everything if you never join one.

Easier to get around
Cards on the Insights screen now say where they take you, and screen
titles are more consistent throughout the app.

Plus: smaller fixes across Trends and Settings.

Thanks for driving with Efficiver.

### 1.4 — 2026-07-21

What's new in v1.4

Apple Watch app
Efficiver now lives on your wrist. Start and stop drives from the
watch, glance at your live score, distance, and time mid-drive, and
get coaching cues without touching your phone. Add the Efficiver
complication to your watch face for one-tap access.

Smarter savings
Wallet Watch now prices your driving with a physics-based power
model instead of a flat formula — and it works through your entire
drive history, including drives from before this update. Every
drive is priced under the fuel type you drove it with, so switching
vehicles later never rewrites your past savings.

Live drive stats on your lock screen
The Live Activity now updates your efficiency score, distance, and
mistake count throughout the drive — right on the lock screen and
Dynamic Island.

Clearer Auto-Start setup
Auto-Start needs "Always" location access to detect drives in the
background. The toggle now explains this and takes you straight to
the right permission instead of silently not working.

Efficiver Pro is coming
Advanced Trends analytics — the efficiency forecast, idle lever,
and component analysis — are becoming part of Efficiver Pro.
Purchases arrive in an upcoming release.

Plus: drive-start audio now plays reliably on CarPlay with the
radio on, GPS status moved inside the gauge, the Start screen's
weather line adapts to larger text sizes, and accessibility
improvements across every screen.

Thanks for driving with Efficiver.

### 1.3.1 — 2026-07-06

Gear Setup is now clearer and more reliable:
• Each gear shows the exact speed range it covers — no more overlapping or confusing numbers.
• Adjusting one gear no longer changes the others unexpectedly.
• "Reset to Default" now properly restores the standard gear speeds.
• Simpler, plain-language guidance for setting your shift speeds.

### 1.3 — 2026-07-04

What's new in v1.3

CarPlay support
Efficiver now runs in your car. Tap the Efficiver tile on CarPlay
to start tracking, see your live score and distance on the head
unit, and tap Stop to save — voice prompts play through your car's
audio. Works wired or wireless.

Annual savings projection
See how much you'll save this year by driving efficiently. Set up
Wallet Watch with your fuel cost and currency, and the Insights
screen shows a projected annual savings number that grows as you
drive.

Year Recap
A shareable recap of your driving year — total kilometres, average
efficiency, top drives, and savings — surfaced from the Insights
screen.

Smart forecast with an idle lever
Trends now shows your forecasted efficiency score and a lever to
see how cutting idle time by 5%, 10%, or 20% would change it.

Pattern insights + anomaly detection
A Patterns card surfaces what's driving your scores day-to-day.
Drives that fall outside your usual pattern get flagged on the
Sessions list so you can spot what went off.

Plus: a redesigned Insights screen with Savings and Trends
highlights, units and currency that match your region, a more
reliable Live Activity Stop button after the app is closed, and
Dynamic Type-resilient onboarding.

Thanks for driving with Efficiver.
