Sam wants to read QR codes with his phone, and wants to know what app would be best for it. There are plenty of options out there that can read both QR codes and bar codes. There are even plenty of apps that can also generate them. RedLaser is a good option.
When you install a smartphone app, there's a good chance it will come with push notifications turned on by default. For example, Facebook's Messenger app will be able to pop up a notification whenever you receive a message on the service. Depending on how many messages you receive on Facebook, this could be quite a battery drain for your phone.
Leo decided to try out Facebook Messenger this week since Facebook has decided to force users to use it instead of the regular Facebook app for private messages. Leo says that not only does the app deplete your battery by constantly monitoring your activity and location, but you also can't turn off notifications on messages for longer than 8 hours in the app. As a result, Leo was more than happy to delete both the Messenger app and the Facebook app from his phone. He'll just continue to use Facebook on the desktop instead.
Wes is in the market for a tablet for reading music. Leo says that while there are tablets that cost less that can do that, Leo advises to use the iPad. There are so many apps that are musician centric, including transribing music, many musicians are now using iPads rather than having sheet music when they play in a performance. So the iPad is really the best option for that because it'll do so much more. And it's worth spending the extra costs. And you don't need the latest. An iPad 3 would work just fine.
Don wants to know if there's a Bluetooth printer that he can use with a friend's Samsung Galaxy Tab 10 tablet. Leo says that there are, but another option from Google is Google Cloud Print, which prints from any internet connected printer anywhere in the world. So if he can get on Wi-Fi, he can print.
Mike shops at Amazon, and has noticed a change in permissions that would allow Amazon to send him text messages. Leo says the cool thing about the Android system is that they would show him what permissions are enabled and which ones an app takes advantage of. So at least he'd know going in what they want.
David needs an app that will track his Android phone in case he loses or misplaces it. There's an app on the Google Play store called "Android Device Manager" that will do this. It also comes with a kill switch to wipe out his device should it get stolen. He can ring the phone to locate it, or remotely wipe it.
Adam wants to know how he can record his guitar riffs on the Microsoft Surface RT and convert it into synthesizer. Leo says since Adam has a digital interface, that's half the battle. But the issue is whether or not he could find an app that would do this on Windows RT. If this was an iPad, there would be tons of options.
Glenda is a dog walker and she wants a GPS tracker that her clients can access so they can see where their dogs are. Leo says that's a nice idea. Most smartphones can do it, and there's a great app called Glympse she can use. It's on Android and iOS she can share her location in real time on Google Maps. Waze also has GPS tracking.
Garmin also has GPS trackers for dogs that she can place on dog collars.
