Telephony-as-a-service company Twilio (a ProgrammableWeb sponsor) is set to announce new volume pricing for heavy users of its Twilio SMS API. The company had previously dropped the price for SMS twice, but did not yet have published volume pricing. Those using over 500,000 SMS messages a month will now pay a fraction of a penny per SMS.
Collaboration company 37Signals bought the popular Ember iPhone app, which uses the company's Campfire API (our Campfire API profile) to display and update chats. The app has been renamed 37Signals Campfire and is now available for free (previously $9.99).
