RidePulse vs Shimmy Diagnoser
Shimmy Diagnoser is a low-cost vibration analyzer. You enter your car from its database, drive at the speed that shakes, and it shows the vibration on a live graph and marks whether it lines up with the engine, the tires or the propshaft. A Help Book on its website explains the causes.

What Shimmy Diagnoser does that RidePulse doesn’t
- Propshaft (driveshaft) vibration, which RidePulse doesn’t track yet.
- A one-time price with no subscription.
- A live graph during the drive, for a passenger who likes to read the data as it comes in.
Where RidePulse is different
- A verdict in plain words, with a confidence level and a suggested check, not only a graph.
- Guided tests with spoken prompts and quality checks: phone flat and still, sensors fast enough, GPS speed steady.
- A braking test, an idle test with the AC off and on, and a comfort score based on ISO 2631-1.
- History, before-and-after comparisons and a pre-purchase report.
Which one to pick
Pick Shimmy Diagnoser if you want a cheap one-time tool, you’re comfortable reading a frequency graph, and you suspect the propshaft. Pick RidePulse if you want the app to run the test and tell you, in plain words and with a confidence, what the vibration may point to.
RidePulse is a screening tool, not a professional diagnosis. Results depend on phone, placement and road. Have a qualified mechanic inspect any suspected fault.
