Stuff not mentioned.. (multi-platform solutions)
1. Awareness!
Got this for free when it came out, basically lets you listen to music until someone speaks(or any noise.. you set what kind of noise or level) then cuts it so you can hear them
2. Astrid
Sync multi lists across devices, shared with others too
3. Waze
And get caught out by traffic, cops etc less often

It's how I learn new short cuts in jhb albeit i'm cape townian.. crappy at night when the roads are closed off/impromptu gated communities.
4. remoteMouse
For quick control of pc/notebook etc via wifi/bluetooth. this is an awesome free solution for presentations instead of buying those presenter stuff. buy a cheap laser pointer and you have all you need. ps. who don't cell makers add a laser on phone? can double up as an alert light with lower power setting? would have thought BB would do that btw
5. SoundHound / Shazaam
Can't remember if it was mentioned but this is awesome to quickly do a lookup of what you listening to.. i do it in stores sometimes.
6. Fitocracy
Still looking for best gym tracking app.. this one works well after putting in the effort to set up your routines. thing i like about it is the integration with social networks.
7. Snapspeed
Alternative to instagram.. more filters, more manual but more control over distribution(you can still share with social networks) and image ownership?
8. Onavo (Extend & Count)
You know BIS compression.. this does it for you iPhone & Android based phones too. Crappy thing is uploading photos on the go.. but then i do this from wifi at home usually.
