Common Questions
Does the app need GPS or internet?
No. Strideloft uses only the device motion sensor. It works offline and does not make network requests.
Why does the SPM display show a dash at first?
The cadence display needs at least two detected foot strikes in the rolling window before it shows a number. Start walking or jogging and it will appear within a few seconds.
Where is my run data stored?
Runs are saved in a JSON file in the app's local Documents folder. They do not leave the device unless you export them using the share button in History.
How do I export my runs?
Open the History tab and tap the share icon (top right). This opens the iOS share sheet with a CSV file you can send to Mail, Files, or any app that accepts text files.
What is the Pace & Stride Lab based on?
The cadence ranges come from aggregate recreational-runner data (runoapp.com pace guide and sport-calculator.com cadence chart). The stride-length formula is the standard definition: speed in metres per minute divided by steps per minute. Height adjustment is based on PMC12222555 (2025 kinetics study). Individual results vary by ±5–10 SPM.
What changed in 1.2?
Version 1.2 adds the Pace & Stride Lab, a Cadence by Pace Zone reference table, Personal Bests in History, CSV export, and a fix for saved runs not recording the custom target zone.
