It couldn’t be easier!
- Add and track multiple runners
- Designate events as workouts or races
- Select participants for an event and start tracking
- Get your results, including lap and finish times

---

All data is securely stored on your iPhone. No ads, tracking, or external servers. That also means that CalcuSplit will work anywhere, even in areas with no cell service!

If you want more features, CalcuSplit premium adds the following with a one-time In-App Purchase:
- View each runner’s race/lap history
- View past events and export the results as HTML or CSV for easy sharing
- Bulk import runners from a spreadsheet or CSV file

All core features of the app are available without Premium. If you choose to upgrade at a later date, any results that you previously saved will be viewable and exportable at that time. Try the app out and see if you find it useful!
