The Tawkon app would have probably gone unnoticed in the App Store, but not being approved by Apple in the first place is probably the best thing that ever happened to it.

The developer of the app had been in contact with Apple executives who apparently loved the app. Everything looked fine until they got an email from Apple saying their app couldn’t be approved.

The dev emailed Steve Jobs about it, asking why the app wasn’t approved, to which Steve replied “No interest”. Clear enough! So the developer decided to bring his app to Cydia…

Tawkon is now available via the ModMyI repo. The app supposedly measures the radiations emitted by your phone. I’m not sure if that really works, but if you decide to give it a try, make sure to lets us know what you think.

It’s free in Cydia. You can’t make that any cheaper.

    By which means would this thing be able to measure radiation?

    • I agree with you, which is why I said the app “supposedly” measures radiations. I don’t think there is any actual way to do that given the current hardware of the iPhone.

  • Lol why would apple ever want this in there store. Makes complete sence that they denied it. Looks stupid and probably doesn’t work. I didn’t know the iPhone had a radiation detector built into it. Highly doubt it’s very accurate.

    • doesnt mean it cant be fun to play around with as a joke

      Yet they let stupid apps like those fake phone trackers, which I actually like, into their store. Also, knowing the difference between there, their, and they’re is something you learn in Elementary school. Please go back to 2nd grade and GTFO the Internet.

  • hmm might be worth checking on

  • wes

    Someone launch the app and put the phone in the microwave… we’ll see if it works 😀

  • My guess is that it does not actually measure any “radiation”, but probably senses for example how good reception you have, (The lower reception the more radiation).

  • The app was probably calibrated with an actual radiation device depending on signal strength, then add wifi and Bluetooth to the mix.

  • Pete

    The app could theoretically read current transmitting power (which varies with reception quality) – the “radiation level” will be more or less directly proportional to it.

  • Pete

    On anorher note, does every app have to be “of interest to Mr. Jobs” to be approved? He really likes to play God, doesn’t he. That’s what I hate about Apple most – they keep trying to tell you how to do things; if it weren’t for the jb scene no way I’d have an iPhone.

    • brent

      Some people will never get it. It’s Apple’s store. They decide what is sold in it. How hard is that to understand? That’s how business works. You don’t like the way they do it, you take your business elsewhere. Just because the iPhone/iOS is used by millions doesn’t mean they are obliged to do whatever you want them to do.

      Whether not doing so is a good business decision or not is another discussion altogether.

      • I don’t quite agree they are OUR phones though i don’t hate apple but they are just TO MUCH IN CONTROL

  • Painman

    The iPhone is an awesome piece of hardware that is unfortunately held back by the straitjacket placed on it by apple via iOS. Thank goodness for the JB scene.

  • theogmike

    Nah, I reckon it just gives a radiation level based on what the iPhone is actually doing at any given moment. So if you’re on a call and using Bluetooth then it’s going to show you high levels of radiation as opposed to just sending a message.

  • EduGeek

    Cell Phones don’t emit ionizing radiation anyway so what’s the point in this app?

  • measures radiation? nah this app is a joke.

  • Xepptizz

    I wouldn’t want to send out an app to the appstore which supposedly measures radiation given the delicate situation in japan. No one should take this app serious, but like einstein said; nothing is infinite except for the stupidity of man.

  • Vladimir

    Thumbs up if want a Geiger counter in the next iPhone 5 🙂

  • duhhh why would apple want to risk making the phone look bad and dangerouse and cause law suits…lol

  • Lucky

    perhaps, Developer of the app can give better brief if this app can really measure radiation or its just like other dummy apps.

  • Cell phones don’t emit radiation. This app does nothing but promote ignorance and non-scientific thinking.

    • Pete

      I do agree “radiation” is a very unfortunate term to use especially in the wake of recent events. They however do radiate el-mag waves of various frequencies, so I suppose “radiation” is going on.

  • Noob-Dude

    May be it’s just an application that indicates you are using the Iphone too much, you are now addicted to your Iphone and you are wasting your battery. So it tells you a scary stuff like radiation emissions to lay-low for a while.

    • Brad

      Duh. Winning.

  • milo

    its more probably for the japanese to track their radiation level 😀

  • Nirav

    Its of no use. V measure it or not, must admit making calls is a part of our lives. Cant liv widout it in todayz world. Dan y unnecessary worry. No alternative. V got to roam, v got to use iphone, v got to make calls

    Thank you for your interest in this important issue and our practical solution addressing cell phone radiation. There have been some questions in these comments about how tawkon works – here are some answers: tawkon monitors changing radiation levels based on information extracted from the individual’s phone, and the environment. It’s more complex than the SAR levels provided by the manufacturer (which are maximum possible SAR levels, not actual real-time levels), and the reception bars that you see – although they are both among the factors taken into account.

    If you want more detail: The application was developed by cellular industry engineers in partnership with an RF (radio frequency) lab while using sophisticated equipment (un-echoic RF chambers, base-station simulators, SAR measurement machine). Each device launched with tawkon to the market is being calibrated prior to the launch on a SAR machine (the same equipment used by mobile vendors to qualify their phones before launch to the market).

    • Amit: Cell phones don’t emit ionizing radiation. You can’t be measuring that which doesn’t exist. Stop promoting ignorance, please. K THX BYE.
