Hello everyone,
I am developing an iOS application that relies on accelerometer data for precise motion and reaction-time measurements.
Based on practical testing, it appears that third-party iOS applications receive accelerometer data at a maximum rate of approximately 100 Hz, regardless of hardware capabilities or requested update intervals.
I would like to ask for clarification on the following points:
Is there an officially supported way for third-party iOS apps to access accelerometer data at sampling rates higher than ~100 Hz?
If the hardware supports higher sampling rates, is this limitation intentionally enforced at the iOS level for third-party applications?
Are there any public APIs, entitlements, or documented approaches that allow access to higher-frequency sensor data, or is this restricted to system/internal components only?
Thank you in advance for any clarification.
