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 measures the fuel your driving mistakes waste: hard braking, hard acceleration, idling and driving above a moderate speed. 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.

Screen Time

Scroll when you decide to. Every time you open one of the apps you picked, pourquoi.app asks why. Answering takes a second, and nothing gets blocked. Your screen time, your call. HOW IT WORKS • A question when you open an app. It pops up right away through Apple's Shortcuts app. Guided setup takes a few minutes. • Name your reason. It takes one tap. Saying what you came for turns a habit into a choice. • See what changes. Your answers and your screen time show where your time goes when you're not really choosing. No scores, no guilt trips. HOW ABOUT DOING SOMETHING ELSE? When you open an app without knowing why, or keep going back to it, pourquoi.app suggests a few ideas. It's up to you. And anytime, right from the app or from Control Center, you can start a breathing exercise or a phone-down timer. • Breathe for a minute: 5 seconds in, 5 seconds out. A gentle buzz tells you when to switch, so you can close your eyes. • Put your phone down: an hourglass runs for the time you set. • Step outside for a bit, read two pages, call someone, or make a cup of tea. • While a timer is running, every minute away from your apps adds sand to your jar. Give your phone a little tap, and the sand settles. YOUR SCREEN TIME, IN A NEW LIGHT • Today's screen time, free, right in pourquoi.app. • At setup, see how many days a year your screen time adds up to, based on your own numbers, not an average. • Your goal, tracked day by day against the previous 7 days: less phone time at night, less screen time overall, or fewer no-reason opens. • Your Journal, with your answers, question pauses, and the time you took back. Seeing your Screen Time data requires your permission and iOS 26.4 or later. WHY NO BLOCKERS A blocker decides for you, and the first thing it teaches you is how to get around it. With pourquoi.app, you decide. Your apps stay put, and you can still scroll. You just choose when it's worth your time. THE CORE OF THE APP IS FREE, WITH NO END DATE • Unlimited questions. • Suggested alternatives, the breathing exercise, the phone-down timer, and the jar. • Your stats, screen time, goal, and Journal for the last 7 days. • Question pauses of up to an hour. PREMIUM, FOR THE LONG RUN • Your stats for the last 30 days and since you started, and what they reveal about your habits. • Time spent per reason and why you open each app. • Your weekly Recap, on the day and at the time you pick. • Your full Journal and your own alternatives. • Longer pauses (2 hours, 3 hours, or until this evening), plus vacation mode. • A minimum gap between questions, and answer buttons that stay in the same place. • More time slots, besides the nighttime one, during which pourquoi.app suggests something else when you keep reopening apps. Try Premium free for 7 days on the monthly or yearly plan: you won't be charged today, and if it's not for you, cancel at least 24 hours before the trial ends. Otherwise, the subscription starts and renews automatically until you cancel it. Prefer to pay once? Premium also comes as a lifetime purchase, no subscription. With Apple Family Sharing, your family can use Premium too. No ads, and your data is never sold. Your history stays on your phone.
