Roadlock is a dash cam app for your phone with on-device loop recording, optional speed overlay, and a local-files approach. It records while you drive, keeps footage on your device, and avoids forcing a cloud account just to capture a trip.
✓ 3 days of Pro, free — Every Pro feature is on for 3 days. After that, recording stays free.
WHO IT IS FOR
Drivers who want a practical phone dash cam for commuting, rideshares, delivery routes, road trips, and insurance-minded documentation. Useful when you prefer local storage over uploading every minute of driving to someone else’s servers.
WHAT ROADLOCK FOCUSES ON
• Loop recording on your phone so older segments can be overwritten as space fills, depending on your settings and free storage
• Speed overlay to contextualize clips with how fast you were going when GPS is available
• Local files you can browse on the device
• A no-cloud-required capture path for everyday driving footage
WHY LOCAL MATTERS
Dash cam video can include license plates, faces, conversations, and locations. Keeping primary footage on-device gives you a clearer chain of custody for your own clips and reduces casual third-party storage. You still choose if and when to export or share a clip after an incident.
HOW A DRIVE LOOKS
1. Mount your phone securely with a clear windshield view. Follow local laws about windshield obstruction and recording.
2. Plug into power for longer drives; continuous video is battery-heavy.
3. Start Roadlock before you move.
4. Let loop recording manage segmented files according to your settings.
5. After a trip or incident, lock or export the clips you need so they are not rotated away.
GPS AND SPEED OVERLAY
When location services are available and permitted, Roadlock can overlay speed context onto your recording workflow. Tunnels, dense cities, and poor GPS locks can reduce accuracy. Treat overlays as helpful context, not a certified speedometer replacement for legal disputes.
STORAGE REALITY
Phone storage fills up. Loop recording exists because dash cam footage is large. Leave headroom, use a device with enough free space, and promptly save important incidents to a separate album or computer. Roadlock cannot create free space that does not exist.
Free: record, 1 GB loop, time overlay, export.
Roadlock Pro
Motion lock, speed and GPS overlay, and an 8 GB loop. Choose monthly, yearly (starts with 3 days free) or Lifetime, paid once. Subscriptions renew automatically until you cancel them in Google Play.
SAFETY
Do not interact with the phone UI while driving. Set up before you depart. Use a stable mount. Obey recording laws in your region, including notice rules for passengers where required.
PRIVACY
Footage stays among your local files unless you export it. That is intentional: Roadlock is built around your device, not a public feed of your commute.

Roadlock — phone dash cam with on-device loop recording, GPS speed overlay, local files, and no cloud required for core capture.
INCIDENT HABITS
If something happens, prioritize safety and legal requirements first. When it is safe, preserve the relevant loop segments so they are not overwritten. Export copies to a second place if the clip matters for insurance. Note the time and location while memory is fresh.
MOUNTS AND ANGLES
Aim slightly downward to capture hood/lane context without sky-dominated frames. Avoid blocking airbags or required vehicle displays. In hot cars, phones overheat — shade and power help, and some days you may need to pause recording.
