If the heroes of the Bachelor Party in Vegas had used this app, so much trouble would not have fallen on their heads. I recommend this application to those who are used to relying on their phone for everything.
The Friday app is free and supports Android 2.0 and newer versions.
In order to get the alpha version for testing, enter your e-mail, fill in the boxes, in the column «Why would you want to try out Friday» enter labnol.org and wait for the invitation. The lucky ones get their invites every Friday.
What is the beauty of this app? It records all your phone activity: calls, games, music, social networks, e-mail, SMS, places you visited. That is, it tracks almost everything that happens to you, since your phone is always with you.
While there is no activity on your phone, the application is in hibernation, but as soon as you receive a phone call, or SMS, or decide to listen to music, Friday wakes up and starts diligently recording all your business. If you want to remember how many times and when you talked to a certain person, you just need to enter a name in the search and you will get a list of conversations with this person. Or you can choose a date and see what you were doing that day.
All logs are stored on your phone. The application requires internet access only when installing and when geo-locating your photos on Google maps.
