Description

Carat 2.01 can also show App Recommendations on iOS 9.0 through 9.3.2!

Our next release will include settings recommendations for iOS 9.3.3+. We are already collecting the data for this, so stay tuned!

** 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 generally use a lot of energy and and those that specifically do so on your device (but not on most others). This does not make an app 'bad', but this advice can help a user improve their battery life.

== 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!

Ratings and Reviews

Brilliant battery saving app

Sam.Walker22

To everyone leaving bad reviews, this app is not designed to work straight away. Once installed, you need to wait a few days for the app to record and monitor your battery and usage before it can start recommending actions to make your battery last longer. Be patient.

Once it's gathered all the info it needs (about 3 - 4) days, the app starts to tell you simple things you could do to preserve your battery, such as restart this, close that, etc...

Brilliant

This has got me a full day's battery on my iphone 5. The poor scores are from people who don't understand hos to use it. it takes 3-4 weeks before you get a report. I discovered that an app called London Buses was a massive drain on my battery (even though I rarely used it!) and that killing the app would save me 20 mins on a full charge. The report was very accurate! Download, let it do it's thing and BE PATIENT!

Working now, but not really that useful

Moobalube

Ar first it didn't report anything for a couple of weeks so I uninstalled it. This newer version, though, works as per the publicity you read that brought you here.

Within a day or two it will suggest you force close a couple of Apps you'll have resident in the background. If you don't already know how to do that, double-click the Home Button, and press any icon until they all jiggle. Now close any you don't need. That's usually the lot unless you're monitoring or playing something. Do this a few times a day, or whenever you've been using Apps.

Carat won't tell you anything more useful than that.

Update: installed it again a year later to see if anything's changed. After two weeks of opening it a few times each day I'm yet to receive a report. Waste of time.
