I’ve known this app since 2016, it’s really great, without a doubt the best power measurement app on the Play Store ! It’s definitely worth it, I highly recommend it to all enthusiasts !

Excellent app, the best on Google Play. It’s the only one that really works. Very accurate results. Congratulations to the developers. I’m very satisfied, 10/10 !

Excellent discovery ! Incredible level of accuracy and very detailed ! Beautiful usable curves. The torques and powers announced on the technical sheet are very close to the results found. Bravo !

Awesome app tested on several vehicles and results very close to the manufacturer data, even identical, much more accurate than Perfexpert, I recommend

Several tests with several vehicles and the results turned out to be very accurate. Also comparison with a test on a dyno and there was 2 hp near the same power!!

Very accurate app ! Better than Perfexpert in terms of measurement accuracy. Even if the graphic part is “less successful” than on Perfexpert I prefer this app for its reliability ! I add that I come from the scientific field and I really find that this app is much more serious scientifically speaking compared to Perfexpert which gave me power differences of more than 10 hp between the measurements ! Knowing the price of a test on a dyno, this app is a very good alternative to know the performance of your car. We get an idea of the passion that was necessary for the developer to create and constantly improve his app ! Bravo and thank you !

Magnificent app that I use very regularly for my preparations (Aston Martin & Lamborghini among others). We compared the app with three dynos (including a Superflow) and the precision is really accurate. Those who find it too expensive just have to buy a dyno (more than 120,000 euros) or put their vehicle on a dyno where a single pass costs more than the app. Congratulations again to the author.

Awesome ! I had Perfexpert. But here I buy for professional support for a person who takes the trouble alone to develop a product that I find excellent, who is available to answer his customers, who is friendly, precise in his explanations, and so on. Keep it up ! USS PERFORMANCES Switzerland // Elvir Ahmetovic

At the top! Quite simply the best car performance measurement app! I’ve been using it for quite some time now (shame on me for taking so long to rate the app) and the accuracy is still as amazing. The results with Perfect Power are identical to those measured on my tuner’s dyno to the nearest horsepower! I’ve already measured a good twenty cars with Perfect Power and I’ve always had accurate and reliable results! And to top it all off, David is extremely helpful!

Top app once well configured. Being a little perplexed I myself made a comparison between a real dyno and this app the result is just incredible the results are identical to 1 horsepower and the interface is much simpler and better explained than all the other similar apps. I highly recommend it to you.

Super good app giving accurate and consistent results. A very practical and easy-to-use pocket dyno. The results are reliable and have nothing to envy from a traditional chassis dyno. Make sure you follow the conditions of use described on the Perfect Power website and it will be perfect.

Hello, I downloaded this app to do tests on my own vehicles, it is really great and realistic because I also carried out tests on dyno to compare, however, you have to configure it correctly in order to make it as accurate as possible, I recommend this app you can buy it with your eyes closed cordially

Hello I wanted to thank David I am a user of his app which is a work tool that I use every day Dyno and app tests have been carried out 2 to 3 hp difference Thank you for your work and your availability via email for vehicle data See you soon Laurent DLP

Excellent app, works perfectly. I used it to troubleshoot my Porsche 928S4 and now I have a reliable tool that allows me to test the car’s performance gaps based on my work on the engine. I highly recommend this app, which, thanks to the unwavering support of the software designer (impeccable after-sales support), allows me to do excellent work!

Quite simply the best of automotive performance apps and extremely comprehensive !!!! Good work from David who is always available if we encounter any usage problem.

I often do ECU reprogramming and it is really the ideal tool to quantify the gains. Much more accurate than most professionals’s dynos which for the most part are poorly configured and give optimistic values while being cheaper the first time and free all the following times. In addition, the creator is an enthusiast belonging to the automotive world and he is very accessible. If we suggest an idea that can improve the use of his app, he programs it ;o)

I use PerfectPOWER to measure the power of my cars, among others with my M3/// E46. I use it a lot to measure the power with different configurations, after several tests I find almost the same figures (torque/power) the chrono tests are very well done. Many updates by the developer are coming out. In short, a very good app.

Finally an app that is accurate in the measurements!! It’s nice to have a dyno in the pocket and save at least €80 each time you use it

First try of power measurement….. And there!!! Only 1% error on the power and 0.5% on the torque!!! And at the rev indicated by the manufacturer!!! Awesome app, thank you!!! Since time, finally an app worthy of the name.

Pro work, it’s hard to believe but it works and it’s as accurate as a dyno!!! Attention, you must read the instructions carefully because all the parameters are important and the use too, I obtained good results once all the car and usage parameters were perfectly respected. Thank you
