arcSail has been designed to operate exclusively on iPhones and iPads operating Apple iOS 13 or later. (sorry, we don't support Android devices at this time)

We use custom views to optimize screen use for smaller devices, however, while you can perform all the functions across all devices, the screen size of iPad mini, Air or Pro devices generally make them easier to view and operate. Newer devices with brighter screens will be best in bright sunlight.

Users who have bought the arcSail in-app purchase can backup and share their data at any time:

• From the "Backups" list, swipe left and click "Edit"

  • To save the database to Apple “Files” App, tap "Save Backup File"

  • To email a copy of the database to yourself or another arcSail user, tap "Email Backup File"

Almost all data can be exported and imported using CSV file format, including individual race, event or series results, sailors, boats, boat classes, etc.:

• To export, navigate to the screen listing the data you want to save and click the export button at the top of the screen:

  • Tap "Save CSV" to save the results to Apple Files,

  • To email a copy of the results to yourself or another arcSail user, tap "Email CSV".

• To import:

  • From Apple Files, navigate to the arcSail folder on your device, and double tap the CSV data you want to import,

  • From email, open the CSV attachment and use the Export icon to send it to arcSail.

Yes. Events can be created and races can be scored without an internet connection. Internet connectivity is only required to share results.
