Since adding Virtual Assistant services to my list of Personal Concierge services, I have come across some useful apps for my day-to-day tasks. However, the most useful app has been @Trello.
Used primarily as my project management tool, I found it useful for personal tasks and to-dos. I create boards for all of my clients and add them as team members so they can:
log in and add (or remove) tasks, documents, or milestone dates to their company board.
see how much time I have spent on their projects (they have a great feature that allows you to add additional features to each board, called power-ups. Chronos is one of them).
add, remove, or modify calendar events (events will appear on every calendar I link it to).
store documents, photos, and so much more.
The screenshot below is just a snippet of the boards I have active at the moment. Some are 1440 related, some are personal, some are courses I'm taking online, and some are boards for my client's projects.
I could go on and on about Trello, but I think you should check it out for yourself. Here is a code to try it out for free. If you're a small business owner, I highly recommend it! You can thank me later.
