Hi,
I'm making my iPhone / iPad app "Heat Sense" free for a day to celebrate the new year. "Heat Sense" is a simple drawing app that simulates the heat produced by your fingers as you draw across the screen. It's great for entertaining kids :-)

I hope you enjoy it, please let me know if you have any feedback / suggestions.

Heat Sense is a fun and entertaining app to brighten up your phone. Heat Sense mimics the heat produced by your fingers as you draw to create colourful patterns!

Features:

  • Over 25 different colour palettes for different visual effects
  • 66 different preset images to start your designs
  • Turn your fingers into 66 different stamps to start your designs. Kids will love this!
  • Use the Doppelgänger, Mirror or Kaleidoscope effects to make symmetric, eye-catching patterns
  • Take snapshots to save your artwork to the photo library to use as wallpaper

To draw without everything fading away, set the decay rate to zero (tortoise).

Heat Sense simulates the diffusion equation, which is a realistic representation of the dissipation of the heat generated by your fingers as you move them across the screen. Moving your fingers quickly generates more heat than moving them slowly. Try it!

See my website http://www.grahamdennis.me/heat-sense/ for more information

    Set decay rate to hare - I have no idea what I'm doing here haha but it's far too addicting!

    • Associatedgrahamdennis @ graham-dennis on 06/01/2013 - 23:33

      Glad you like it!

    I thought you could wave your phone to mimic writing letters at night with a sparkler and see the end result using the accelerometer.

    Lots of fun. Would be nice to have: Undo function, combine palettes.

    • Associatedgrahamdennis @ graham-dennis on 06/01/2013 - 23:47

      What do you mean by "combine palettes"? Being able to create your own palettes?
      Undo is a good idea, though. I'll think about it.

        I mean this: If I want solar and watermelon in the picture, it cannot be done.When one changes the palette, the whole picture changes.

          That's not actually possible in Heat Sense. Heat Sense isn't like other drawing apps, you don't draw with colour, instead your fingers modify a 'temperature map', and I then use a colour map (the palette) to display that in colour. Imagine that you're drawing in grayscale and I then remap the colour for display. This is why when you change the palette the structure of your image stays the same.

    WOW. Best simulation of being under the influence of substance! Dam those colours are cool.

    Don't know about the kids but I love it. Flying to Singapore tomorrow - guess what I'll be doing? Thanks.

    • daveted on 07/01/2013 - 11:07

      I agree. I just spent 5 minutes at work playing with it. It was hard to stop.

      The kids are going to love this, if they can manage to get it off me first.
      Definately worth $1. Word of mouth should see the money start coming in soon, I reckon.

      • Associatedgrahamdennis @ graham-dennis on 07/01/2013 - 12:16

        Great to hear!

  • alfamale87 on 07/01/2013 - 07:18

    Sweet!

    Thanks for the explanations on how to change the settings in your post. Fun drawing app, kids will definitely enjoy. Best thing is it takes up so little space (3.1mb on my ipad)

  • hashtagbargain on 07/01/2013 - 11:38

    Wow, just spent ten minutes playing with the app, wasn't even interested initially! Thanks op.

    • Associatedgrahamdennis @ graham-dennis on 07/01/2013 - 12:15

      You're welcome :-)

  • Muimuimorris on 07/01/2013 - 15:38

    Great work Graham. Having lots of fun with your app.

  • John Dough on 07/01/2013 - 15:44

    So. Much. Fun!

  • mainbreak on 07/01/2013 - 23:06

    Deceptively fun! Was just expecting a run of the mill paint app, was definitely impressed.
