OK, I may have overly complicated the title. But here is my issue.
I sometimes work alone, sometimes as a team of 3. Either way, I have to keep track of all time that has already been booked and time that is available for new tasks. Right now, I am keeping it all in my head (and each of us do the same). So when the client asks me for something urgent or when we can start work, I usually take a day to calculate and then come back and update him. But most time this does not prove to be accurate as the schedule changes (delays, unpredicted events, etc.) and when the client comes to me I have to tell him that I cannot work today but in X days.
So far, I did not have any negative consequences e.g. client left me in angry, but this is far from professional conduct.
So, I need quality, easy to use (not zillion steps and features) and most important easy to visualize (all my plan for 1 or more months on 1 screen for example, not 10 steps) online tool where I can track my work and available time.
You will say it's easy to reply, right?! For the last year, I have been using all kinds of tools proposed by this community or Internet, and each was not satisfactory. Either too many options or too complicated to enter schedule, or... and in the end I always keep my schedule in my head. I've tried tools like Google Calendar, Trello, Excel sheets, planner tools from MS Office pack, the real board on my wall, stickers, and even dozen online tools which names I cannot recall now.
So is there any such tool around or I have to create one (kidding on the later)? What tools to do you?
Note: 70% or more guys mention google calendar which IMHO is very uneasy to visualize. Maybe I am using it wrongly (being a developer I usually over-complicate things). If you think that Calendar is the right tool for me, then please show me some quality tutorial which will tell me how to use if effectively without complicating things.
