Overall Findings
Most dash cams use looped recording. The camera records continuously on a microSD card. The feed is split into a series of three-minute clips, with the newest clips replacing the oldest clips. Because new data replaces old data, the amount of space on the card stays the same and there’s no need to buy new cards. Dash cam apps work the same way, but have some limitations that are worth considering.
Storage Space: Dash Cam Apps Take Up Phone Space
While both dash cams and dash cam apps record short video loops and replace old ones as new ones are recorded, available storage can be an issue. Dash cams have a set-it-and-forget-it design, where you only retrieve or replace the microSD card when you need to access a recorded clip. With a dash cam app, any space dedicated to that app is going to take away from available storage for other apps, pictures, videos, music, and whatever else you carry around on your phone. It may also reduce the functions of other apps while in use.
Convenience: Dash Cams Work on Their Own
GPS and G-sensors (accelerometers) are found in most smartphones, putting smartphones in closer competition with mid-priced dash cams that feature the same. High-end dash cams often include multiple cameras, more robust memory systems, and higher resolution video. It is generally easier to ready a dash cam than it is to set a phone in a cradle and open a dash cam app. For some people, that convenience is worth the expense of a dash cam. For others, a $100 price tag is too steep when a decent dash cam app costs less than $5 or is free.
Affordability: Smartphone Apps Are Cheap and Sometimes Free
Dash cams, even the cheapest ones, are more expensive than dash cam apps. Most dash cams start at around $100, and dash cam apps can be downloaded for free or, at most, a few dollars. If you’re on a budget, choose a dash cam app. Just be wary of the limitations. You’ll need to harness your phone and launch the app with every drive. Some apps also don’t allow other apps to run in the background. So, if you rely on your phone for music or podcasts while driving, you’ll be short on entertainment.
Final Verdict: Dash Cams Are More Reliable
The only thing in favor of dash cam apps is affordability. While that may be compelling to some people, dedicated dash cams are more dependable. Once installed, you never need to remember to launch an app or to harness your phone. You can also keep a dash cam running in your car when you’re not there. And with additional features like accelerometers and GPS tracking, you’re sure to have more data in the event of an accident, theft, or another incident.
