There are people who are self-employed, e.g., consultants, freelancers, taxi drivers. In order not to keep complex accounting, they use QuickBooks service. This platform has various strong features, but there is no time tracking. Users can't run the tracker to totalize what they did, how much time they spent, when they started work, and when they finished it.
Our customers from California David Allison and Marc Summe hired us to develop the mobile app to solve this problem.
