Welcome, driver. This page answers the most common questions. If you don't find what you need, email us — a real person (the solo developer behind OVERDRIVE) reads every message.
Support email: [email protected]
Typical response time: within 2 business days (often much sooner). We're a one-person shop, so thanks for your patience.
When you email, it helps to include your iOS version, iPhone model, the app version, and a short description or screenshot of the issue.
Flow measures how smoothly you drive — not how fast. Using your GPS and your phone's accelerometer, the app looks at how steady your pace is and how gentle your inputs are (acceleration, braking, and cornering). Smooth, consistent, calm driving scores high. Harsh braking, jerky inputs, and erratic pace score low. All of this is computed on your device.
No — never. Speed cannot raise your Flow score, by design. On public roads OVERDRIVE only ever scores smoothness and discovery. There are no speed or drift leaderboards, points, or rewards on public roads, and there never will be. Timed laps, speed zones, and drift scoring exist only when geofenced to verified racetracks and permitted closed-course events. Any private top-speed figure is a personal stat — it's never ranked or shared.
As you drive, OVERDRIVE snaps your GPS trail to real roads and "paints" the roads you've driven lime on a dark map, revealing your city like a fog-of-war map. Your discovery percentage grows as you explore new streets. Distance and discovery — not speed — are what you're chasing.
Motion (accelerometer) data is used only to score driving smoothness for Flow. It's processed on your device and never sent anywhere. It is never used to rank speed.
By default, everything — your drives, discovery, profile, and stats — is stored on your iPhone, not on our servers. The only data that leaves your device is a coarse, downsampled subset of route points sent to a mapping service to snap your route to roads, plus standard map-tile requests. See our Privacy Policy for full detail.
Because your data lives on your device, deleting the OVERDRIVE app removes your locally stored data. If we later add online accounts, you'll also be able to email us to delete any server-side data. To request a deletion or a copy of any data at any time, email [email protected].
OVERDRIVE requires an auto-renewing subscription (OVERDRIVE Pro) to use the app:
Prices are shown in your local currency and may vary by region. The monthly plan starts with a 3-day free trial; the trial, the price after it, the billing frequency, and how to cancel are all shown before you subscribe.
Subscriptions are billed by Apple, so you cancel through Apple:
1. Open Settings on your iPhone.
2. Tap your name at the top.
3. Tap Subscriptions.
4. Tap OVERDRIVE, then Cancel Subscription.
Cancelling stops the next renewal; you keep access until the end of the current period. To avoid being charged after a free trial, cancel at least 24 hours before the trial ends. You can also turn off auto-renewal on the same screen.
Refunds are handled by Apple. Visit reportaproblem.apple.com, sign in, find OVERDRIVE, and request a refund. We generally can't issue refunds directly, but email us if Apple can't help and we'll do what we can.
Give the map a couple of seconds to load tiles over the network. If roads aren't painting, check that OVERDRIVE has Precise location enabled in Settings, and that you granted at least "While Using the App." For screen-off recording, enable "Always." If map-matching can't be reached, the app falls back to your raw GPS trace and marks it honestly — your drive is never lost.
No. This is the core promise of the app. Speed is never ranked, rewarded, or shared. Leaderboards (when enabled) are for discovery %, Flow, and distance only.
