A free speedometer app sounds harmless. It shows your speed, maybe runs a few ads, and costs nothing up front. But many of these apps are not free in any meaningful sense. You pay with location data, behavioral data, and attention.
How “Free” Apps Really Make Money
Speedometer apps sit on unusually valuable information: where you drive, when you drive, how fast you drive, and which routes you take. That can reveal home and work patterns, routines, and even whether you spend weekends at tracks, meets, or off-road trails.
App Store privacy labels can help you spot the difference. Apple explains its labels here, and “Data Not Collected” is the standard worth looking for.
The catch is that some apps avoid saying they “sell” data while still feeding it into ad systems. Real-Time Bidding is the clearest example. When an ad loads, information about you can enter a fast auction chain, as TrustArc explains. Privacy International has documented how opaque that ecosystem is. From a driver’s perspective, “share” versus “sell” does not matter much if your location is still broad enough to profile.
The Real-World Cost
This is not just an abstract privacy debate. Regulators have been taking action against location-data brokers and ad-tech firms for exactly this kind of behavior, including recent FTC enforcement.
For drivers, the downside is obvious:
- your routes and routines can become part of a commercial profile
- your data can be combined with other sources to infer more than you intended
- your participation in enthusiast activities can become visible to outsiders
- a “free” utility can quietly turn into a long-term surveillance product
And there is a second trap: some “free” apps use the free tier to funnel users into recurring charges while still monetizing unpaid users through ads and data.
Why I Took a Different Route
This is why eyeSpeed uses a one-time purchase instead of ad tech, subscriptions, or data harvesting. It is one of very few speedometer apps with a “Data Not Collected” App Store label. Speed is calculated on-device. There is no route history sent to a server and no business incentive to squeeze value out of your location.
Driving It Home
Free speedometer apps often cost more than they look. The price just shows up somewhere else: privacy, profiling, and pressure to upgrade later.
If an app needs your location to work, fine. If it needs your location to make money, that is different. For a utility this simple, paying once for privacy can be the cheaper deal.
