Discover why the Speedometer Simple app is a game-changer for tracking your real-time speed on bikes and cars. Read our full review and setup guide today!
Have you ever been riding your bike on a highway, fully enjoying the breeze, only to suddenly realize you have no idea how fast you’re actually going?
Or maybe the speedometer simple on your old scooty or family car has completely stopped working?
I’ve been there. A few months ago, the meter cable on my old bike snapped right in the middle of a long ride. With speed cameras popping up on every corner in Indian cities and highway e-challans becoming a daily nightmare, driving without knowing your speed is incredibly stressful.
I needed a quick fix. That’s when I stumbled upon an app on the Apple App Store called Speedometer Simple.
At first, I thought, “Can a mobile app really track my speed accurately?” But after using it on my daily commutes, my mind was totally blown.
Let me tell you exactly why this little app has become a permanent feature on my phone—and why you probably need it too.
What is the “Speedometer Simple” App?
Developed by WATT APPS, Speedometer Simple is exactly what the name suggests. It is a clean, easy-to-use GPS-based application that turns your iPhone or iPad into a highly accurate digital speedometer.
Currently sitting at #12 on the App Store’s Navigation charts with over 1.18 Lakh ratings (averaging 4.7 stars!), it’s clear that people are loving this tool.
Whether you are cycling, driving a car, riding a motorcycle, or even sitting by the window seat in a train trying to guess the speed, this Speedometer Simple app does all the heavy lifting.
Why You Actually Need It (Real-Life Scenarios)
You might be wondering why someone would download a separate app for this. Here is the reality:
- Broken Dashboard Meters: Fixing a broken Speedometer Simple can be a hassle and expensive. This app gives you an instant, free replacement on your phone screen.
- Avoiding Traffic Challans: Speed limits change rapidly on city roads. Keeping your phone mounted with a giant, readable speed display helps you stay within the legal limits and saves you from heavy fines.
- Bicycle and E-Bike Tracking: Most basic cycles or e-bikes don’t come with advanced digital meters. If you want to know your top speed while cycling, this is the perfect solution.
- Train and Bus Journeys: Admit it, we all love checking how fast the Vande Bharat or Shatabdi express is running!
Why I Love This App (And You Will Too)
I test dozens of apps every month, and most of them are filled with confusing menus and unnecessary clutter. Speedometer Simple wins because it does one job perfectly.
Here are the features that stood out to me:
1. Giant, Easy-to-Read Fonts
When you are driving, you cannot afford to squint at a tiny screen. The app uses massive numbers to display your speed. Even if your eyesight isn’t perfect, or you aren’t wearing your glasses while cycling, you can read it with just a quick glance.
2. The “No Internet Required” Magic
This is the biggest game-changer. The app relies completely on your phone’s internal GPS satellite receiver, not your 4G/5G data. If you are road-tripping through the mountains where there is zero network coverage, this app will still show your speed flawlessly.
3. Detailed Trip Statistics
It doesn’t just show you how fast you are going right now. If you hit the record button before you start, it acts like a travel log. Once you reach your destination, it gives you a summary: your maximum speed, average speed, and total distance traveled.
4. Highly Customizable
You can switch the units between km/h (perfect for India), mph, or knots (if you are on a boat!). Plus, you can change the interface color to match your mood or your car’s dashboard lighting.
Is It Actually Accurate? (The Real Test)
This was my biggest doubt. How accurate can a phone be?
To test it, I mounted my phone on my car’s dashboard, opened the app, and hit an empty stretch of road. I matched the speed on the app with my car’s built-in digital Speedometer Simple.
The result? It was almost identical. There is a tiny lag of about 1 or 2 seconds because the phone needs to ping the satellites in the sky, but the actual speed calculation is spot on.
Remember, since it relies on the sky, it won’t work perfectly if you are driving through a long underground tunnel or sitting deep inside a concrete basement. But out on the open road, it’s remarkably precise.
Actionable Tips for First-Time Users
If you are downloading the app today, here is how to get the best experience:
- Get a Good Phone Mount: Don’t hold the phone in your hand while driving. Invest in a sturdy handlebar mount for your bike or a dashboard mount for your car.
- Give It a Clear View: GPS works best when it can “see” the sky. Place your phone near the windshield so the satellite connection is strong.
- Watch Your Battery: GPS tracking consumes battery. If you are using the app for a long road trip (more than 2 hours), make sure your phone is plugged into a charger or power bank.
- Use the Free Version First: The app is free to use. There are some ads, but they aren’t overly annoying. Test it out for a week before deciding if you want to pay to remove the ads.
Conclusion: Should You Download It?
Absolutely. Speedometer Simple does exactly what it promises without overcomplicating things.
Speedometer Simple lightweight, highly accurate, and incredibly useful for those moments when you just need to know how fast you are moving. Whether you are an everyday commuter, a weekend cyclist, or just a curious traveler, this app deserves a spot on your smartphone.
Try it out on your next ride, and I promise you’ll find yourself opening it more often than you think!

Frequently Asked Questions (FAQs)
1. Does Speedometer Simple require an active internet connection? No! The app calculates your speed using your phone’s built-in GPS hardware. You don’t need active mobile data, making it perfect for remote road trips.
2. Is the app completely free to use? Yes, the core features of the app are entirely free. It does contain some ads to support the developers. You have the option to buy a premium version (via in-app purchase) if you want an ad-free experience.
3. Why does my speed sometimes show zero when I am moving? This usually happens if you are in an area with a blocked view of the sky, such as an underground tunnel, a dense forest, or a basement parking lot. The GPS needs a clear line of sight to satellites.
4. Can I use it on a bicycle or an electric scooter? Absolutely. Many users prefer this app specifically for cycling and e-bikes because it provides a large, readable dial that tracks top speeds and trip distances perfectly.
5. Does using this app drain the phone battery quickly? Continuous use of GPS will drain your battery faster than normal usage. For short city commutes, it’s totally fine. For long highway trips, it is highly recommended to keep your phone plugged into a charger.
