Portree is a group contact application.
With this app you can contact friends, groups, organisations and customers with just a few taps.
The app supports SMS* (text) messages, iMessage emails tweets and phone calls.

The app supports large groups and can split large groups at time of sending an SMS to get round your phone carrier's limits on number of recipients for a text. The app can work as a phone tree with more than one person involved in sending messages.

You can export and import using email and airDrop and can also save CSVs to use on your Mac or PC.

Contacts can be selected from your address book or added in the app.
Templates for sms iMessage tweets & emails can be set up in advance.

History records are saved for messages sent.

*sending sms messages and making phone calls requires an iPhone.

The app cannot make simultaneous phone calls so it will work through a list of people one by one so you know who to call next.

The first time you use the app you will be asked to grant Portree access to your contacts and to Twitter. You should say 'YES' to these questions and can change the setting in the settings app, privacy, contacts option.
