TechBuilding a Dashcam iPhone App<br>August 5, 2026By Thomas McGee

I have always thought dashcams were a good idea.

You hope you never actually need the footage, of course, but if something happens on the road, having a clear recording can settle questions that would otherwise come down to memory, conflicting stories, or whatever somebody happened to notice in a stressful moment.

The basic job is simple: point a camera at the road, record what happens, and keep the footage around long enough for it to be useful.

So when I started looking at dashcam apps for the iPhone, I assumed this would be a fairly solved problem. Modern iPhones have excellent cameras, plenty of storage, GPS, fast processors, and large displays. Put the phone in a mount, tap a button, and you should have a perfectly capable dashcam.

Instead, I found myself frustrated by the same two categories of apps.

On one side were polished apps with the features you would expect, but they often came with accounts, cloud services, analytics, tracking, or some other system designed to collect and store information that did not need to leave the phone in the first place.

On the other side were the more privacy-focused options. I appreciated what they were trying to do, but many were difficult to use, missing basic features, or built in a way that made privacy feel like a compromise you had to endure.

I did not think those should be the only choices.

You should not have to hand a company a detailed record of your life just to get a good dashcam. You also should not have to use a frustrating, limited app just because you care about privacy.

So I built MightyDash.

The Problem Was Bigger Than Video

A dashcam recording is not just a video of the road.

Depending on the settings, a single trip can include the route you took, the time you left, the speed you were driving, the places you stopped, the people in the car, the conversations you had, the homes and businesses you passed, and the license plates and faces of people who never agreed to be part of the recording.

One clip might not say much. A collection of clips can say quite a lot.

It can reveal where you probably live, where you work, when you are usually away from home, which places you visit regularly, who travels with you, and what your normal routine looks like. Add an account, device identifiers, location history, analytics, and a cloud copy, and what started as a simple safety tool can become a remarkably detailed personal profile.

I am not saying every dashcam company uses every piece of data in the worst possible way. That would not be fair, and different apps have different policies. The problem is more fundamental than that. Once another company has a readable copy, your privacy depends on its security, business model, current policies, future policies, employees, vendors, and whoever might own the product later.

That felt like a lot of trust to ask for something that could work locally.

The simplest solution was not to write a longer privacy policy explaining all the wonderful things I promised not to do with the data. It was to build the app so I never received the data at all.

Privacy Should Be Part of the Architecture

MightyDash is private by design. It does not require an account. It does not upload recordings to a MightyDash cloud. It does not include ads, analytics, telemetry, tracking, or third-party SDKs. The recordings stay inside the app on your iPhone unless you explicitly decide to save or share one.

That is not meant to be a marketing trick. It is a product boundary.

If I do not need your trips to provide the feature, I should not collect your trips. If the app can record, organize, play, and manage videos on the device, there is no reason to route those videos through a server I control.

This also makes the experience simpler. There is no account to create, password to remember, subscription to manage, cloud library to configure, or upload to wait for. You open the app and use it.

That is the part I think gets missed in a lot of privacy conversations. Privacy is often presented as a limitation, as though respecting the user necessarily means removing useful features. But good privacy can make a product easier to use because it removes systems that never needed to be there.

The harder challenge was making sure the rest of the app did not feel stripped down.

Start With the Simplest Possible Job

The main recording screen is intentionally straightforward. Mount the iPhone in landscape, open MightyDash, tap record, and drive.

While it is recording, the road stays large on the screen. The elapsed time, recording status, Recording Health, and stop control are easy to find without turning the interface into a cockpit full of gauges. On supported iPhones, you can also see a small preview from the front camera when you are recording both directions.

That simplicity matters...
