Free iPhone app which uses the camera to detect your heart rate.

"The first and only app that allows you to check, track and tweet your heartbeats on the iPhone 3GS or the iPhone 4.

Pulse-o-matic is a stylish and simple app that uses the iPhone’s camera to take your pulse. It’s easy to use - all you need to do is place your finger over the camera and Pulse-o-matic will display your heart-rate, graph-style, on the screen."

How it works: http://pulse-o-matic.com/How_It_Works.html

Note: This program does not use a random number generator, it legitimately attempts to determine your pulse.

If you're having issues, please read about the iPhone's limitations.

    What's 4% off $0.00?

    is it accurate at all?

  • csg001 on 24/04/2011 - 22:13

    +/- 10% accuracy for me on iphone4

    • jv on 24/04/2011 - 22:45

      mine fluctuating between 50 and 90 bpm… so i'm either having a hearth attack, or it's not very accurate…

      • dmc900 on 24/04/2011 - 23:06

        a heart rate between 50 and 100 bpm is normal.
        But I don't see why your heart rate would fluctuate so quickly.
        This app may not be that accurate, but I like the thought of measuring your pulse with a camera.

        • BlueSpruce on 24/04/2011 - 23:15

          I think its a fun app, but one day we will have this technology !!!

        • llama on 24/04/2011 - 23:17

          One day, perhaps.

          But that day ain't today.

        • StewBalls on 25/04/2011 - 00:42

          It's a lot closer than you'd think, but just not with an iPhone camera! ;)

    If you look at the application it self, it's simply a white guassian generator for rand# that have a mean of 74bpm and one standard deviation of 12.

    In addition to that, it also uses the camera length to capture lights. So if you let more light in, 'in theory' (according to the equation) your heart rate should be a bit faster.

    So all in all, this is just a fun app that doesn't do anything except novelty fun!

    • UFO on 25/04/2011 - 17:12

      so its junk then…. thanks for extra info.
      whilst im happy to see 'good' apps appear here for free (ive picked up some really good ones posted here), this aint one of them.
      neg vote.

      • freespace on 26/04/2011 - 00:02

        Please ignore him. I assure you the app does its best to detect your heart rate. It won't always do a good job because the iPhone isn't exactly designed for this purpose and it is trying to detect changes in the order of a few %. This means if the sun happens to shine a little more brightly it would confuse it before it adjusts.

        • UFO on 26/04/2011 - 00:12

          ummm… so then the useful of this app is questionable at best. "it wont always do a good job" pretty much sums it up :).

        • freespace on 26/04/2011 - 00:18

          @UFO there is a difference between "questionable" and "unreliable". Questionable is when the app might not actually be trying to detect anything and is simply fooling you somehow. Unreliable is when the app doesn't always do what it is suppose to. Think of the difference between a question character and an unreliable person. Apples and oranges.

          The app isn't as reliable as I would like due to the limitations inherent in the hardware and the environment. It is however 100% unquestionably not trying to fool you by producing random numbers.

          "as I would like"…. are you the author?
          if so, good job- im not trying to offend (or review your product).

          but this website isnt for reviewing products such as yours, it lists 'bargains'… and in my humble opinion this isnt a bargain. as a freebie people can try it (and its good you let them do so), but a bargain as defined by this website… I dont agree (hence the neg to OP).

        • freespace on 26/04/2011 - 00:26

          The site has a section just for freebies, which suggests to me anything free is considered a bargain.

        • Cyb3rGlitch on 26/04/2011 - 00:27

          I don't think he was arguing that his app was a bargain (although, it's free, so I personally consider it to be). He's refuting the blatantly incorrect claims against the app, and rightly so.

          I do apologise if I sounded offensive. You can see that I didn't neg this bargain at all, it's because i sense the novelty value in the apps and 'can' be further enhanced into something that's actually useful!

          When I tested out the programs, my goal was to understand the theory and see how 'accurate' they are compared to a sporting EKG/EGC heartbeat monitor and medical devices such as stethoscope. Nothing to do with interllectual novelties, rather the 'reliability'.

          So kudos to you, I had a lot of fun playing with it and I look forward to your development!

      Incorrect. There's nothing random about the algorithm, the descrepancies are caused by error introduced by limitations of the iphone camera.

      • CuteChocobo on 25/04/2011 - 23:08

        Please correct me if I am wrong. I have yet come across a gimmick that can accurately measure heartbeat from a camera such as an iphone one!

        Actually doesn't even have to be accurate… just remotely accurate will do it for me! I've downloaded 8 heart beat apps, 6 paid and 2 free for university Software Engineering 203 course and also asked for the source code for some. All to me are just gimmicks (for fun). None of them are serious about it!

        In addition, they used RAND# in their code. So what is there not to say about randomness?
        If you want to see the code, just send the authors for their source code and say that you are interested in their app for a school project.

        • freespace on 26/04/2011 - 00:00

          You are wrong.

          So here is the function that does all the heavy lifting, for your reading pleasure:

          http://pulse-o-matic.com/source.m

          In fact, here is some test data that was collected:

          Knock yourself out.

          Cheers,
          Steve

          P.S. If you dedicated the same energy you put into belittling other people's work and implying they are all liars and similar low-lifes that will do anything to make a buck, perhaps you could have done some research and found http://pulse-o-matic.com/How_It_Works.html where a graph of the actual values is shown.

          P.P.S. It is also gratifying naive to see you expect to receive actual source code when you ask commercial developers for what is the heart of their product.

          P.P.P.S. The reason I don't mind showing my heavy lifting code is because frankly any one with two brain cells to rub together could have came up with it given a bit of time.

          Thank you. I've been thru to your site and many others. Reading thru maze of pages trying to understand the logic behind it.

          As for your project, Steve, I am rather farmiliar it is Keith Wilson's HeMon project. I am not implying that your's won't work, but is not 'accurate' using the technology avaiable on the iPhone 3GS and iPhone 4 which I both tested. So whilst it is considered as a contribution, the inaccuracy is considered as a gimmick/novelty to professionals.

          Hopefully one day as the technology enhances, which I am sure it will. I am sure that you can come up with a code that can measure heart beat with 2-3% tolerance! Only time will tell for now.

    • freespace on 26/04/2011 - 00:03

      Camera length isn't something you capture light with, and I don't know what theory you are talking about.

    this product is junk for measuring pulse. Good idea though.

  • cib0_madu on 26/04/2011 - 10:31

    I don't see how a camera can measure your pulse… as previously stated by others, fun novelty app, but has no real value.

    Got to love the fact that people +1 the script-kiddie despite the fact that the source code has been posted which contradicts him.

    • CuteChocobo on 26/04/2011 - 13:48

      Script kiddie? Hah!
      Sorry to bust your bubble! I am not even closely related to programming field, more towards biochemistry & molecular biologist.
      But what ever makes you happy I guess!
