It records the road
Full-screen camera at 1080p, saved in 3-minute loop segments. The app keeps the last 2 hours of driving and automatically clears the oldest unlocked clips first, so you never run out of space mid-trip.
Your speed.
On camera.
On the record.
TrueSpeed Cam is a dashcam app that records video with your live GPS speed, time, and location burned into the picture itself — so if you're ever pulled over, you don't argue about your speed. You show it.
- Speed burned into the video file — not just on screen. It stays in the exported clip.
- A second-by-second CSV speed log for every trip, ready to share with the video.
- 100% on your phone. No account, no cloud, no API, no subscription server.

Does TrueSpeed Cam need an API or a server? No.
Everything happens inside the app, on your phone. The camera records, the phone's GPS measures speed and position, and the app stamps both into the video before it's saved — all on the device, even with no signal.
There's no account to create, no cloud upload, and no API between you and your proof. Your clips and speed logs live in the app's storage on your phone until you share, export, or delete them. This website is just information — the app does all the work.
How it works
Mount it, tap record, drive.
Three things happen at once while you drive — the video, the stamp, and the log.
It stamps every frame
High-accuracy GPS updates at least once per second. Speed, date, time, coordinates, and heading are burned directly into the video picture — part of the file itself, not a caption you can switch off or fake later.
It keeps the receipts
Every trip also gets a CSV speed log — one row per second with timestamp, speed, latitude, longitude, heading, and GPS accuracy. Pulled over? Tap LOCK and the last 5 minutes are protected forever. Then play, share, or export the clip and its log together.
Burned into the video
What anyone sees when they press play
No special player, no app needed to view it. The proof is in the picture:

Because the data is part of the video image, the clip carries its proof anywhere it goes — texted to someone, shown at the roadside, or saved for court. The matching CSV log backs it up second by second.
Features
Built for one job: proof
No feeds, no followers, no extras. Every feature exists to make your recording complete, protected, and easy to hand over.
Giant live speed display
A huge speed readout over the camera view, updated every second from high-accuracy GPS — readable at a glance, and mirrored in the burned-in overlay.
Loop recording, zero babysitting
3-minute segments, last 2 hours always kept. Old unlocked footage deletes itself in order — start it at the beginning of a trip and forget it.
One-tap LOCK
Something happen — a stop, a near-miss, anything? One tap protects the last 5 minutes. Locked clips are never auto-deleted, ever.
CSV speed log per trip
Timestamp, speed, latitude, longitude, heading, and accuracy — one row every second. Opens in any spreadsheet and pairs with the clip from the same trip.
MPH or KM/H, your call
Switch units anytime, set a speed-limit warning, and choose 1080p quality by default. Auto-record can start when driving is detected.
Private by design
No sign-up, no cloud, no tracking server. Your video never leaves your phone unless you export it. The screen stays awake while recording, so nothing is missed.
Saved clips
Find the moment in seconds
Every clip is listed with its thumbnail, time, and speed summary — no scrubbing through hours of footage.
Play it. Share it. Done.
Tap a clip to play it with the overlay already in the picture. Share or export the video and its CSV log together — to your lawyer, your insurance company, or anyone who needs to see exactly how fast you were going and where.
Locked clips sit at the top, protected. Everything else rotates out automatically as new footage comes in.

Straight talk
What GPS proof can — and can't — do
TrueSpeed Cam is strong supporting evidence. Here's the honest picture, because proof you over-trust is worse than no proof.
GPS is not calibrated radar
Phone GPS speed is accurate in normal driving, but it can lag a few seconds when you accelerate or brake hard, and it's not a certified, calibrated instrument like police radar or lidar. Treat the video + log as strong supporting evidence, not a legal guarantee.
Signal can drop
Tunnels, parking garages, and heavy storm cover can weaken GPS. When that happens the overlay shows the accuracy getting worse — the recording never pretends to know more than it does.
iPhone records while the app is open
On iPhone, recording runs while TrueSpeed Cam is on screen — switching to another app pauses it, which is true of every phone dashcam. Android can keep recording in the background via a foreground service. Either way: mount the phone and plug it in.
The video + log together are the proof
Speed alone can be questioned. Speed burned into road video — with time, place, and heading — plus a second-by-second log is a much harder story to argue with. That's why TrueSpeed Cam always keeps both.
Before you drive
A 2-minute setup that makes it count
The best evidence comes from a phone that's mounted, powered, and pointed at the road.
- 1Mount the phoneA windshield or dash mount with a clear view of the road ahead. No holding it — ever.
- 2Plug into the car chargerVideo + GPS is battery-hungry. A charger keeps long trips fully recorded.
- 3Allow camera & precise locationGrant both permissions and set location to high accuracy so speed updates every second.
- 4Do a 1-minute test driveRecord a short loop, play it back, and confirm the speed in the overlay matches your dashboard.
Questions
Frequently asked
Do I need an API, an account, or internet for this to work?+
No. TrueSpeed Cam does everything on your phone — camera, GPS, overlay, storage. There is no account, no cloud, and no API involved in recording or keeping your proof. You can record in airplane mode.
Internet is only used if you choose to share or export a clip somewhere.
So what is this website for?+
Information only — what the app does, how the proof works, setup tips, and these answers. The app itself is self-contained; this site never sees your videos, your location, or your logs.
Is GPS speed proof enough in court?+
It's strong supporting evidence, especially with time, location, and video burned in plus a second-by-second log — but no app can promise a legal outcome. GPS can lag briefly under hard acceleration and isn't a calibrated instrument. Show the video and the log together, and let them speak as a pair.
Where are my videos stored?+
Only on your phone, inside the app. The last 2 hours of unlocked footage are kept in a loop; locked clips stay until you delete them. Nothing is uploaded anywhere by the app.
Does it work on both iPhone and Android?+
Yes — TrueSpeed Cam is being built as one app for both platforms. One difference: on iPhone, recording runs while the app is on screen; on Android it can also keep recording in the background. A mount and a car charger are recommended on both.
What happens when storage fills up?+
The oldest unlocked segments are deleted first, automatically. Locked clips are never touched by the loop — tap LOCK any time something happens and that footage is safe.
