No — that's the whole point. Nudge works through your phone's existing Messages app. Save a number, start texting. No app store, no downloads, no updates.
Any phone that can send SMS text messages. That means every iPhone and every Android phone. If you can text a friend, you can text Nudge.

Google Calendar, Outlook / Office 365, and Apple Calendar (iCloud). You can connect multiple calendars at once on the Pro and Teams plans.
Yes, absolutely. Cancel anytime from your account settings. No questions asked, no hidden fees. Your free plan stays active even after cancelling Pro.
Your calendar data is only read when you send a message and is never sold or shared with third parties. We use OAuth so we never store your Google or Microsoft password.
