** PLEASE READ BEFORE INSTALLING **
Carat is the first app to generate personalized recommendations for improving your battery life. After observing your use of the device for *a week or more*, it will start to generate reports just for you. You should open the app once every day or so, with an Internet connection turned on, until you start seeing results.
Although Carat uses Location Services (thus displaying the little icon), it is NOT using your GPS and is NOT running in the background. The app uses almost no power.
** Thank you! **
Ever wondered why your battery is draining so quickly? Just install Carat, open it every few days with an Internet connection turned on so it can send data to our servers, and within a week Carat will start recommending Actions (just for you!) and even predicting the improvements you will see. Although Carat cannot measure energy use directly, it infers what apps are responsible using advanced machine learning methods.
And it's free!
As you use your device, Carat occasionally takes measurements and sends them to our backend servers in the cloud, where we apply cutting-edge algorithms to determine what steps you can take to use less energy. By collecting snippets of non-personal data from a large number of devices, Carat does not need to run continuously in the background. Nothing we collect identifies you, personally.
Carat will tell you which apps it thinks are hogs (they use a lot of battery) and which are bugs (they use a lot of battery on your device but not most others). Being a hog or a bug does not make an app 'bad', but a user trying to improve their battery life can use these designations to adjust their behavior.
== Carat Features ==
- Action List telling you how to improve your battery life and by how much
- Device information detailing exactly what data we are recording
- Reports apps that are using lots of energy and whether that is happening on other devices, too
- Detail views let you dive down into the data
- Low-overhead sampling requires almost no energy or CPU
- J-Score tells you how your battery efficiency compares to other users
- Sharing features let you post/tweet/blog about your experience; more users means more data which means better recommendations for you
Carat is under active development by a team of researchers in University of Helsinki. We are constantly making improvements, adding features, and giving you more knowledge about how your device is using energy. Remember, knowledge is power!
What's New in Version 1.14
-You can now see the number of samples sent by Carat on your device
-Restore compatibility for iOS 5.1.1 and later
This app seems to be just what I need, but click on it and it crashes before it can even fully open. Totally frustrating
It's a shame because it looks like it would be really useful app.
I'm giving it 2 stars Instead of one because of its potential utility I'll try it again in a couple of weeks and if the developers have Fixed it ill redo my review. If not Ita'll take it down to one star.
***Downloaded it again, same problem, so gave it one star.
btw My iPad version works fine. Only the iPhone app is a problem.
Carat has lots of flaws
Carat insists that one of my top three energy hogs is an app that I don't have on my iPhone. I had it years ago on my iPhone 4, but deleted it and never re-installed it when I upgraded to 5 and later to 6. It tells me I have minimal memory left, which doesn't jibe with what my settings say. This definitely does not show an accurate analysis of my phone contents or usage. I emailed the company to ask about it, but they never answered.
Crashes on startup.
It worked fine then I couldn't use it because it needed a newer system but now it's back it says but it doesn't work at all,it just crashes on startup. I'm on iPhone 5 6.1.4 by the way
