The Talko app, despite what it might sound like, is not a messenger application that allows you to send pictures of tacos to your friends. The free iOS app makes your phone calls more like emails in that it combines live chatting, voice messaging and multimedia attachments. Ideal for organizing teams, the tool lets people working together communicate more efficiently.
The Talko app also incorporates the email-like feature that allows people to review past conversations using what SpringWise calls "voicemail-style audio snippets." Similar to iOS 8 audio messaging, it allows people to record messages and have them appear in a thread format. You can also organize your messages using subjects, tags and priorities. You can even bookmark and forward information.
