Waste of Money

- Bad Interface
- Hard to use
- Not even worth 1.99$
- Regret the waste of money

This works.

This app works if you use it correctly. Is comparable to other virtual dynos you will find on the web.

It does what it’s supposed to

It’s an APP that will give you an estimate of whp, Set your parameters right and it will be close, not perfect but close. Again it’s an app not a real Dyno

Adapt to other displays please

I would say it’s okay.
But the iPhone 12 Pro Max, as I have, has rounded corners and a notch above.
Please adapt it more to this type of display.
It’s a pain to use it. Many buttons close to the bottom border, triggering the „home button“ on those phones. Really looking weird to have options and buttons inside or nearby the notch.
Please fix this.

Support / Developer Vanished

Don't purchase this app for now is my suggestion. The support and developer sites are now gone. So I cannot follow up with questions from prior contact BEFORE I bought Log Dyno. Hopefully support will return in the futures.

Useless

It simply doesn’t work. Save your money

barely works

works half the time i keep getting a error message

Not ready for primetime

Forces you to enter very specific car data every time you launch the app. The open CSV button launches a file browser that doesn’t show any of your actual files. Opening the app via tapping an MHD log file CSV from the iOS Files app, just displays an incompatible format error. Support is only provided via FB - I’m not setting up a FB account just to get support for an app. I want money back - this is just completely unusable!

Response from developer

There is literally a Contact Us button in the settings which is support via email. Also, only need to input car data ONCE, after that, the app saves the values.

Useless

This app is using time stamp and RPM to determine HP and TQ. It’s completely inaccurate. I am not sure what are the internal equations the developer intend to use, but in comparison to real life numbers, real Dynos and other similar apps, this one is grossly off. Don’t waste your time or money on it.

Response from developer

Usually when someone contacts me with an issue regarding a measurement it turned out in 100% of the cases to be a user error. I and plenty of other people have went on a dyno to confirm accuray, and measurements were spot on. I am confident in the app's performance, not so much in the dyno operators' which is in case the user.

Useless

Did you know a bolt on 340i makes 1026whp? Me either.

Response from developer

Anyone who has contacted me with difficulties got help and I solved his issue, which was user error in 100% of the cases. If you would have contacted me via email, your issue could have been resolved a lot easier.

It’s so off

It’s trying to tell me my Bolt-On coyote F-150 is making 700+ whp and like 1800ft/lbs lol

Response from developer

I am always available via email as support and happy to help, but can't help if never contacted me. Anyways, those who contact me with similar results always end up facing the fact, that it was a user error, which is easily resolved.

No accurate.

This app doesn’t deliver accurate numbers.

20 pull data log the same day and all have different results with a delta of 60 hp.

Response from developer

You need to use logs that don’t have wheelspin or bumps in them. Make sure your rpm curve is smooth and doesn’t have dips and spikes. It has been dyno prooven multiple times that the app is dead accurate, but you need a clean log. Email me the log you have issues with and I will point out what the problem is. Hope this helps.
