Nobody likes filling in hours in a time-tracking tool. It is something on the side that has to be done. It is often forgotten which leads to huge backlogs of time-tracking to do. To help prevent this, a daily or weekly reminder to fill in your hours will help. The Project Hours mobile apps will be updated so users can schedule reminders that will appear as notifications on their phones. I am not sure yet how to display reminders on laptops and PC's. Email reminders? Something to consider.
I will also add warnings for timers that run longer than a day. Usually these timers were started to measure time on a tasks but the user forgot the stop the timer. Perhaps a reminder every hour is useful..
Easy sign-up from mobile phones
Currently, if you are interested to start using Project Hours, you have to sign-up via the web site. But I think it would help finding new customers if companies can sign up up and organise their projects and team directly in the Project Hours iPhone or Android app. It will also help to advertise Project Hours on app listing sites like https://getapp.com
Enough to do, to be continued..
