C2K for iOS Is in Internal Testing

Table of Contents

Update: C2K has completed testing and is now available on the App Store.

C2K started as an Android app - I published it to F-Droid and later put it on Google Play too. People kept asking about an iPhone version, so I built one: a real Swift/SwiftUI port, built from scratch for iOS.

It's now far enough along that I'm running it through internal TestFlight testing.

What's inside

Same app, same idea, native this time. All six programs are there - Pre-C25K, Couch to 5K, Couch to 10K, Bridge to 10K, One Hour Runner, and 5K Improver - with voice coaching, optional GPS distance and pace tracking, treadmill mode, and workout history. No account, no subscription, no ads, no tracking. Location data stays on the device. Nothing phones home.

One thing iOS gets that Android doesn't (yet): lock screen and Control Center controls during a workout, so you can pause and resume without unlocking your phone.

Where things stand

Right now it's internal testing only, which on TestFlight means I have to add each tester by hand through App Store Connect - there's no public link at this stage. Once internal testing clears, the plan is an external beta with a link anyone can use, and then a real App Store release.

Want in on internal testing?

Email me at c2k-beta@hackerapps.com with the Apple ID email address you want added, and I'll send you a TestFlight invite. Apple caps internal testers at 100, so there's room, but do use an email you actually check - that's how the invite arrives.

If you try it, I'd like to know:

Send feedback to the same address, or through TestFlight's built-in feedback option if you'd rather.

Source is available on GitHub at github.com/AnalogGhost/c2k-iOS. Thanks in advance to anyone willing to poke at an early build.
