Customer Reviews

Its been a rough road, but once againa good app

I’ve been through each beta version, during which I’ve oscillated from enamored to infuriated at the many ways in which this app has screwed up each step. I feel they’ve finally hit upon a nice blend of functionality, design and price. As long as it keeps working as-is, and they don’t try to charge for another version, I’ll keep supporting their development. Give it a try, its a nice piece of software now that they’ve got their act together.

Grasping Defeat Out Of The Jaws Of Victory

This app, and what they’ve done to it, ought to be a case study in business school. Took an app that did a lot of things well and removed features for existing users (unless you went back to an older version) and replaced the good app with a terrible one. The primary features that this was good at was flawless syncing with Google Contacts (2 way and flawless) and LinkedIn integration (now an in-app purchase even if you bought the original versions with this included). Now it’s a hot mess. Guys, are you trying to go out of business?

Great Idea, Poor Implementation

This app has great potential but as of right now it seems more like a work in progress than a completed product. Profile pictures of my contacts were being assigned to multiple other contacts, switching places, and other such nonsense. I’d say it needs just a but more polish before I’d recommend it to anyone.
