Frequently asked questions about Speed Test Reflexes, along with how to contact us.
-
How accurate are the measurements?
The app's measurements depend on your device's display response speed and processor performance. They are accurate enough for relative comparisons on the same device, but they are not suitable for strict comparisons across different devices or for medical or scientific purposes. Please enjoy them as a reference for reflex training.
What devices are supported?
The app supports iPhone running iOS 17.0 or later and iPad running iPadOS 17.0 or later. It may not work correctly on earlier OS versions.
Where is my measurement data saved?
All measurement data is stored only on your device. No data is ever sent to an external server. As a result, deleting the app erases all of your data, so please be aware of this.
What measurement modes are available?
The app has the following eight measurement modes.
- Normal mode: measures your reaction speed to a change in screen color
- Light mode: measures your reaction speed to a light turning on
- Sound mode: measures your reaction speed to a sound playing
- Vibration mode: measures your reaction speed to the device vibrating
- 9-Button mode: measures how quickly you tap the correct button out of 9 buttons
- 16-Button mode: a higher-difficulty reaction test using 16 buttons
- 25-Button mode: the highest-difficulty reaction test using 25 buttons
- VS mode: two players compete head-to-head to test their reflexes
Is there a charge for the app?
The app is completely free to use. There are no in-app purchases either.
