I don't often do product reviews here, but I recommend this one a lot so here goes ... I have a smart watch, the Garmin Vivosmart (warning: affiliate link). I really like it and its integration with my android phone so I thought I'd share my experiences.
Since I started working for myself almost 6 months ago, I've had to get to grips with running a company myself, and I must admit that the paperwork was one thing that stopped me from making this move sooner! I've kept everything in order and I'd like to mention one tool which has helped me hugely with that: Harvest.
