Tawkon Smartphone Radiation Monitoring App Released on Android

An app that purports to monitor how much radiation your smartphone is producing at any given time, and then warns you when it is excessive has been released to the Android Marketplace.

Tawkon claims that its patent pending algorithms collect and analyse RF data in real time to determine the radiation levels produced by your phone. As you would expect, in an area of poor reception, a phone has to work harder to obtain a signal, and therefore gives off more radiation, so the phone’s location in relation to the nearest base station is critical. In addition, the design of the aerial on the phone will make a difference, as will how the person is holding their phone – as Apple knows only too well. The app also takes into account the antenna’s distance from the body using the proximity sensor.

Every phone has a certified Specific Absorption Rate (SAR), but using this data Tawkon claims it is effectively creates a dynamic SAR rating, depending on your location – it calls this the tRi or Tawkon Radiation Indication.

However, while radiation on mobiles sounds like a scary issue, the fact is that after decades of use, no clear link has been made between mobile phone use and ill health, specifically cancer, a question we put to Friedlander.

“Several neurological studies and health reports have found a connection, but there is still much debate," Friedlander told TrustedReviews. "Many health bodies around the world are currently recommending cell phone users... undertake precautionary measures today, {and} not wait a few more years until research is concluded. Tawkon is providing a solution exactly to these requirements. We believe in empowering users with information so they can make their own decisions."

On Android, the app sits in the notification bar at the top at all times, and changes from green to red and will prompt you if your radiation levels rise during a call. If also offers stats to show how much radiation you’ve avoided, and been exposed to and will chart it over time. It also uses location data to chart radiation levels with the intention to create a worldwide map of ‘hotspots’ around the world.

Tawkon attracted some attention a few months ago when it started an online petition after Apple declined to approve it for the App store. The app has been available on Blackberry, for $9.99, for some time, while an ad supported version is now available for free for Android users.

A version for the iPhone could be on the cards though according to Friedlander. “The iPhone team gave us great compliments on our app and we established there is a solution that will require minor API modifications to enable Tawkon on the iPhone.”

I'm pretty sure you can replace this app with some common sense + a look at the reception meter + looking up the SAR value for your handset. And since your handset is constant, you can pretty much simply look at the reception meter and try to avoid using the phone in areas of low reception. They did a very thorough job with that application, I'll give them that.

Wow. What an awesome app. No, wait, I mean what a waste of time. Nothing to see here people - move along!

It pains me to say but I totaly agree with Apple's stance, this should be nominated as most useless App of the year.

I can just imagine users worrying about the radiation their device is givin off while chatting outside on a nice hot sunny day!

This is a serious problem people!

It's made me so bloody anxious that I've just had to smoke a whole packet of Silk Cut to calm down.

I have to say, once I've spent more than about 20 minutes on a mobile call I often get a headache. That may be the fault of the guy I'm spending so long talking to, but it does make me wonder how much radiation my head has just absorbed.

So, how are you supposed to see what the radiation levels are while the phone is pressed up against your ear?

This is a Samsung ONLY App so bit of a waste of time really, I dont think apps should be released in the android market if it only works with one model of phone?

@Simon, that is the problem with having an Android phone

@John McLean:

Have to disagree with you: I'm with Chris on this one, and can't blame it on the person(s) I'm talking to...


You can check them afterwards, or during if you're using a headset/speakerphone.

If you're actually worried about this kind of thing, get a bluetooth headset and keep the "killer" handset away from your skull...
