A product that I worked on for a year: Tact chat, has been released on the App Store. I was involved with the project up to the public beta release, and now the owners have managed to push it over the line. It’s a unique (highly opinionated) concept, and I think a cool product. If you ever wanted a chat app, minus the social network and surveillance capitalism – think family, friends, hobby groups – try Tact at justtact.com.
