Frequently Asked Questions

What is SplitShiftr?
SplitShiftr is a GPX activity editor for iOS. It lets you adjust pace, speed, heart rate, cadence, and split times for running and cycling activities — all processed locally on your device.
Is my data safe?
Yes. All GPX file processing happens entirely on your device. Your activity data never leaves your phone. See our Privacy Policy for details.
What can I do for free?
The free version includes 1 free trial edit with ads. After that, a SplitShiftr Pro subscription unlocks unlimited processing and removes ads.
How do I subscribe to SplitShiftr Pro?
Tap the Pro badge or upgrade prompt in the app. Pro is available as a monthly (£2.99/month) or annual (£19.99/year) auto-renewing subscription.
How do I cancel my subscription?
Go to Settings → Apple ID → Subscriptions on your device. Tap SplitShiftr Pro and select Cancel. Your access continues until the end of the current billing period.
How do I restore my purchase on a new device?
Open SplitShiftr and tap "Restore Purchases" on the upgrade screen. Your subscription is tied to your Apple ID and will restore automatically.
What file formats are supported?
SplitShiftr works with standard GPX files. You can import GPX files from any fitness platform and export the edited file to share or re-upload.
Can I use SplitShiftr for cycling?
Yes! Toggle between Running and Cycling mode in the editor. Cycling mode displays speed in km/h instead of pace (min/km) and uses cycling-appropriate presets.
