App Notifications is an iPhone client for Apple push notifications. In addition to showing notifications from Twitter, E-Mail, etc, you can receive updates from Tender.
You only need to do this once. Clicking that will send you to the App Notifications site. Also, Tender will fill in your token for you. All you have to do is approve with App Notifications and save the Tender webhook.
App Notifications lets you revoke the authorization to let Tender ping your iPhone. However, we'd appreciate it if you'd also remove the webhook setting in Tender so it stops trying to ping you.
App Notifications is a free iPhone app download. It currently costs $1 for 10,000 notifications, but we are working on a deal that would make Tender pings free for our users.
