My online office


The 4th Office made it into my favourite app list after a couple weeks. The app recognised who are my most important contacts and enabled me to work with them efficiently. I love the chat and email integration - it gives my email a totally new perspective, so I can use it as a messenger for business. I would recommend it to anyone that gets more then 20 emails per day - it really decluttered my inbox and helps me stay on top of things.
