  • Freezes

    Freezes up regarding easy exit
  • what?!? no log or trig?!?

    no log, no star!!

  • Feature Request

    Would like the slide rule to remember its position (calculation) when leaving and returning to it.

    Would like to be able to rotate to all four orientations.

    Would like support for full ipad resolution.

    Please continue compatibility with iOs 3.1.x

    If I put a value of 4 on B scale under 2 on A scale and look at B scale under 5 on A scale, it does not quite line up to the expected value of 10.

    Looking forward to these modifications to upgrade my rating to 5 stars.

    Thank you.
