Here is one of my screens filled with some widgets I like:
1. The first one I have on there is the APN on/off widget - what that basically does is it turns off cellular data (very handy if you live in South Africa, and cannot afford the ludicrously expensive data packages available) - get it here
2. The second one might puzzle you a bit, it's my Blizzard Battle.net Mobile Authenticator - if you play any of Blizzard's games on your PC (Like World of Warcraft or Star Craft 2), then this is just a little extra security. When logging in on your Battle.net account, it will also ask for the code this widget generates. It keeps on generating new ones, so if you're also worried about account theft, then you got to get this on your Android phone - get it here
3. Next to that I have a flash light widget, which instantly turns on the LED on the back of my phone, turning it into a handy flash light :) - get it here
4. The first icon in my second row is a link to one of my Google Reader feeds (to this blog actually) - for that I have the 3rd party Google Reader app gReader - I find it works a bit better than Google's own version. Get it here
5. Then I have a data counter widget, showing me the amount of incoming and outgoing data for the month, both for Wi-fi and 3G - once again a handy little app if you have to pay extra for cellular data - get it here
6. Next to that is a battery widget, the normal battery icon doesn't give you an exact estimate of how much battery life you have remaining, this one gives you a nice percentage value - get it here
7. This is the stock standard Google Search Widget that comes with the phone, here you can type anything in, and search either the web, your apps, your contacts or all of the above. You can tap the Mic icon to say what it is you are looking for :)
8. The last widget I have on here is Evernote - this is a notes taking app, and allows you to quickly take a written note, a note with a photo or video, or recording something. It works well, and is a nice and quick way of making a note. The only thing I didn't like about this one is that you must register for a free account to be able to use it on your phone - I have registered on close to a billion sites already (or so it feels). Anyway, get it here
There are lots more cool widgets out there of course. Feel free to leave a comment and suggest some of your favourite widgets, I'll have a look, and if they're as cool as you say, I'll do a little review of them!
As always, till next time!
