Tango messenger app: Why you shouldn't use it

The Tango messenger app is probably the worst app for privacy I have ever come across. If you have any concern for your privacy at all, you should not use it. Below I will list just a few of the things that concern me as far as privacy and the Tango app.

  • Tango saves all your contacts to their server

    When you install the app on your phone, it seems to try to sync with all the contacts in your phone. Although there is a setting to stop this called "Save Address Book to Tango" under "App Settings", this setting is on by default and by the time you have installed the app and want to turn this off, it is too late and your contacts have already been saved to their servers.

  • It sometimes allows people to see your phone number

    This one really surprised me and it has happened about 3 times to me. I have opened the app and instead of a contacts name being displayed, tango displayed their phone number. These contacts were only tango contacts who I had never met and who had never given me their phone number. I even checked that is was actually the person's phone number by sending them a regular text and surprisingly, it was their actual phone number. This problem seems to me like it has something to do with the person changing their name in the apps character encoding

  • You can't remove contacts

    For some reason, in the Tango app, contacts are added just by chatting to someone, for most people this probably isn't the behaviour that is expected so if you install the app and go about chatting to many people, your contacts

Android apps to test your mobile cell and wifi data

Often when traveling I have to rely on my trust Nexus 4 android phone to connect to the interwebs, be it on the phone itself or when tethered to my laptop. As such, I often want to test both the wifi and cell data connection on my phone. Most of the time I need to run these test when looking at a new hotel or condo to rent, but also when the connection seems a bit dodgy in an area that was good.

Here is my list of recommendations of apps to test your mobile data connection

3G 4G WiFi Map & Speedtest

This is the app that I have used the most lately when testing my connection.One of the main reasons being is that it has a coverage map built in allowing you to see what mobile carrier has the best coverage, and also which carrier has no coverage in your area. I think this data is collected from people using their app which may be a good or a bad thing in your opinion, but it if it improves the app and does not collect any of my other data, then why not (this feature can be turned off).

The good:
  • Good dashboard giving much information
  • Cell data and Wifi
  • Signal Compass
  • Coverage map
  • Cell tower map
  • Free
  • No ads
The bad
  • More detailed information would be good
  • Speedtest download reported in "KBPS" (all capital). unclear is this is Kilobits or KiloBytes
Network Signal Info

This app seems to be a more general purpose app rather than an app to help you improve or find a better signal. What I really like about it is the extensive information that it provides....
