Jorte is a free calendar/to do list application for the Android platform. I have downloaded it for my Nexus One and I would say that this is the first app that has started to make me think that Android can rival the iPhone. The calendar comes with a choice of monthly or weekly views. Not only will it sync with your Google calendar but I have been able to get it to sync with Outlook. The syncing process was very simple and straight forward.
It is very simple to add new events to the calendar and you save a click on the iPhone by simply having to tap on the date in question to bring up the dialogue box into which you add your event details.
The killer feature of this app occurs when you enter the location of the event. It immediately becomes a link to Google maps that shows you your current location and the location of the event. I nearly fell over the first time that I saw this. I often think that there is a lot of hype around geo-tagging and a lot of apps mke use of it to broadcast your current location which I personally think can be a bad thing as it can tell the bad guys when you are away from home and possibly give them an insight as to how long it will be before you return home again! With this app I see a really positive use of geo-tagging.
Within the options you can download a variety of national holidays, although there is a mistake with the UK holidays as they have both the first and last Mondays in August as official holidays when in reality it is only the last one.
There is also an option to have a to do list at the bottom of your screen and I have found this invaluable for just making quick notes about upcoming projects to which no fixed timeline has yet been established.
All in all I think this is the most useful app that I have so far found for the NexusOne, but if you know of one that’s better then do leave me a comment and let me know.
