Entrain Schedules Light Exposure to download the app and start using it

iOS: Research shows that light exposure is a major factor in your body's rhythms, so mathematicians have built an iPhone app called Entrain that cuts jet lag time and gets your body adjusted to a new time zone faster.

Developed by researchers at the University of Michigan, Entrain is a guide that takes user input to give you a schedule that promises to overcome jet lag faster. It doesn't use light sensors or any other automatic input, so it's important that the user submits data—it's not magic!

The science behind the app is that light is the primary diving input to the body's circadian rhythms, so if you feed Entrain your current light input schedule, it can figure out light stimulus that moves your body clock from one phase to another. Detailed math is available in a paper at PLOS:

These schedules are mathematically proven to adjust you to new time zones as quickly as possible. Light is the primary driving input to the circadian clock, and by recording your lighting history, we can simulate your body's clock and make recommendations for behavior.

So the first step in using the app is to schedule your current time zone, and when you are reaching a new time zone. The next step is the important one: choose the brightest light you can be in during your trip. This is what Entrain uses to figure out a schedule for you that will get your circadian rhythm in line with your new surroundings. From then on, it's a matter of telling the app the light you are currently getting in your scheduling and following the recommendations, which update as you add input.

While it's a great app, for a short visit, it might not be worth the trouble of avoiding jet lag. And if you don't have an iPhone, there's an Android version on the way, but for now, you will have to rely on other ways to cheat jet lag like acting by your destination's time zone while flying.

The official website of Entrain linked below has more details about the app and the science, but if that's not for you, feel free to download the app and start using it.

How To Speed Up Your Android Chrome Browser [QuickTip]

When you’re using the Android version of Google Chrome, you probably have experienced the time when Chrome takes way too much time to load, or crashes frequently, or acts sluggish when scrolling.

If you are used to Chrome and don’t want to opt for another browser for all your online needs, here is a quicktip to speed up your Android Chrome browser. Using this tip will significantly improve your scrolling experience and it will reduce frame rate drops.

Speed Up Your Chrome Browser

Start by opening the Chrome browser app on your Android. Go to the address bar. Type Chrome://Flagsin the address bar and then press Enter.

You will be redirected to the Chrome://Flags settings page. Next, look for the flag called “Maximum tiles for interest area Mac, Windows, Linux, Chrome OS, Android”.

Tap on default and choose 512 from the drop-down. If your device has less than 512 RAM, its best that you choose anything below that figure to prevent Chrome from taking over all of your device’s memory.

Tap on the relaunch button at the bottom and you’re done.

If you want to go back to the default settings, head back to the Chrome://flags page and “Maximum tiles for interest area Mac, Windows, Linux, Chrome OS, Android” then choose default. Relaunch your Chrome browser for the effect to take place.

Speed up Chrome with a simple fix

After finishing his Bachelor of Commerce degree at the University of Alberta, Sterling made the move to Vancouver Island in British Columbia. Within a stone's throw of mountains, ocean, and complete wilderness, he mountain bikes and skis during the day and is hopelessly connected to his phone and computer at all other times. His writing "career" started as he penned about his escapades while skiing and has slowly progressed to freelance marketing and promotion throughout British Columbia. Interested in anything tech and gadget related, he has thoroughly enjoyed his transition of writing for AndroidPIT.

Chrome is one of the most popular browsers for people on both PCs and Android devices.  However, one persistent problem is unique to the mobile version of the Chrome browser: delayed scrolling.  Ever since Google has replaced the AOSP Browser with Chrome, this lag has been an issue when scrolling through a website or trying to resize it.  Here’s a quick tweak to help solve the issue.

Thanks to redditor, u/erythrocytes64,  this simple tweak makes Chrome for Android noticeably faster and smoother. What the change seems to do is allocate more RAM for Chrome and as such, it improves the scrolling speed. Here’s how to do it:

• Type chrome://flags into the URL bar in Chrome on your Android device
• Find Maximum Tiles for Interest Area
• From the dropdown, change it from default to 512
• Tap on the Relaunch Now button

One thing to note, however, is that on devices with less RAM, this tweak might purge the memory much faster and causes your device to “clog up”.  If this is the case, change the value in the dropdown box to something smaller, say 256. Be sure to also note that a lot of the options in the chrome://flags are of the browser are entirely experimental, so be careful if you choose to play around with any other settings in there.

Has the tweak worked for you? I’ve noticed a much more fluid scrolling experience when using Chrome on my Nexus 7.

Radar Beep: Speed camera warning for drivers

Features & Use

Radar Beep is an app that warns you of approaching speed cameras and radar traps. With the launch of the app you activate a background process that scans the environment for safety cameras. So the information is as current as possible, when you load the app at first you'll be prompted to download a file with corresponding radar control positions. You set your country as a defualt and there are packages for the United States as well as many different countries in Europe. You can check how much speed camera data is available for each country via the national table.

Your exact location is recorded by GPS. A map shows where you find yourself and speed cameras are marked with corresponding icons in the map. As you approach a warning point, a beep from the app will increase in intensity as you get closer and closer to the trap. A large display will keep you informed about the prescribed speed for the area you're currently in. In addition, you will be shown the type of speed trap coming up, your current speed and how far away the speed camera still is.

In the test, the app warned of upcoming speed cameras very well. If you do not have your phone connected via Bluetooth to a navigation device and have not selected a specific route the app will just show you alerts for speed cameras in the area. Since the app shows a lot of potential safety cameras though, the message density can be correspondingly high and not always apply to the road on which you find yourself or even plan to take. Getting alerts for a specific route only is possible only in conjunction with a navigation device. Unfortunately, this does not apply to Google Maps and its navigation system. Connection to an external device must be done via Bluetooth.

In most cases too, the app alerts you to possible speed traps. This means many of the speed cameras you're being warned about are no longer current or accurate, but simply possible. Freshly mapped speed traps on the other hand are only displayed if you have updated to the most current data package.

Note: About the legal use of speed camera apps: it is your responsibility to arm yourself with the relevant information regarding the legality of using an app such as this in your local area. Local law enforcement may fine you for using an app or device that displays speed camera locations and radar traps. Also, you should not use an app such as this as an excuse to disobey speed limits. Driving safely at all times is the best solution. 

Screen & Controls

The user interface of radar beep is very clean and clear. The background map (Google Maps) can be zoomed in on as much as necessary and you can check up in advance where possible cameras could be lying in wait along your route. Your current speed is displayed over a large area at the top of the screen for easy visibility. Warnings are also nice and large and include all important information. In the settings you can decide exactly what you want to be alerted about in the app. In addition to fixed radars and possible mobile speed cameras there are some other warning categories, including, for example, a radar section, possible police checks and other 'danger' points.

The notifications for each category can be adapted individually. You can turn off notifications for all but a few special special warnings, or you assign a notification or an additional tone to them. Voice notifications can also be enabled. The app is configured quickly and easily and worked first time in the test. For quick access, there is also a widget.

Speed & Stability

In my tests, Radar Beep worked very well and accurately. Most of the possible radars were not currently present, but the app's warning of excessive speed was, in every, case, offered with plenty of time to safely slow down before any traps. A stable internet connection and a good GPS signal are absolutely necessary in order to take advantage of the app on the whole route though. Battery consumption and data usage on my mobile network were limited.

For a free app, Radar Beep has the basics covered nicely. / © AndroidPIT/Radar Beep

Price/Performance Ratio

The app is available for free and includes a banner ad at the bottom of the screen. If you want to remove this, you can donate any amount above a dollar to the developer.

Final Verdict

Radar Beep reliably delivers maps with all sorts of mobile radars, permanently installed cameras and other traffic control alerts. Even when a possible camera does not end up appearing, it is better to be safe than sorry and it doesn't hurt anyone to stick to the speed limit. One of the most impressive features of the app is the simple interface and quick setup. Compared to the competition, there are still some functions, such as congestion indicators and warnings of certain dangers, that would be a useful addition for Radar Beep. Google Maps navigation support would also be more desirable than the necessity for a Bluetooth connection to an external navigation device in order to receive notifications while using turn-by-turn navigation. All in all though, the app does what it does well and therefore scores a neat four stars out of five. There's room for improvement, but as far as the basics go, it's all good.
