Where can I download the Elevyn app?

Elevyn is currently available on iOS. Get it from the Apple App Store. The listing shows whether a free trial is available for new subscriptions, how long it runs, and the terms, so you can try the full app before you pay.

After you install, you can explore in Demo Mode with sample data, or start a subscription (through the flow in Settings > Subscription) to work with your own shop.

An Android version is not available yet; check elevyn.app for updates.
