Can I use my PercenX Pro subscription on both the web and iOS app?

Yes. Your PercenX Pro access is associated with your PercenX account, not just the device you used to subscribe.

If you purchased Pro on the web, sign in to the iOS app with the same PercenX account to access your Pro benefits.

Likewise, if you subscribed through the iOS app, sign in to PercenX on the web with the same account.

Tip: If your Pro subscription doesn't appear on another device, first confirm that you're signed in to the same PercenX account you used when subscribing.
