Tipr is now available as a Twitter service, which means you can use it via text message from your cell phone if you don't have a mobile web browser.

How do you use it? Follow these simple steps:

1. Befriend tipr.
2. Wait for Tipr to recprocate the friendship (about 30 seconds).
3. Use Tipr's TwitterBot by sending it direct messages. For example d tipr 10.25@20 will calculate a 20% tip on a $10.25 check.
4. If you ever have questions d tipr help.

Tipr TwitterBot could take up to 1 minute to respond to your query.

Note: if you are not getting text messages from Tipr, check your Twitter settings. You must have your account set up to receive Notifications from Tipr and you must have set your preferences such that Notifications are sent to your mobile.
