From fasil fikreab:
Peopler is a group texting app. It helps you create clubs and communicate with them via text. You can consider these clubs as little organization or a small company. You become a founder of this organization/company when you create a club. Then you add people as your CFO, COO, HR, Secretary, or whatever you want to name them. These titles will come with assigned tasks. A title, such as CEO, CFO comes with the job, and many or one person can have them.In short Peopler will help you run a small company via text. Use it to plan stuff, like you wedding or your trip to Tahoe. Try it.
