Latest Update Caused Problems - Now Fixed!

By cb_cb1 (Pcmac user)

UPDATE - The display issue from v7.6.1 is fixed - via 7.6.2. The calc is now back to the great tool that it has been for quite a while and I look forward to continuing to use it for another few years. Thanks. PRIOR - The most recent update may have made for compatibility with the latest iOS (I haven't tried it yet on my iPhone and likely won't based on this experience) but it no longer works on my iPad that has an older iOS. The background graphics no longer scale up to the screen size so the touch points for the calc do not agree with the visual indications for the buttons. Avoid this version. Wait until it is fixed if you have an iPad with an older iOS.
The REAL thing...

Latest speed enhancement is phenomenal! Thank you. Now if we can have it always “ON” when it comes up, then it would be perfect! Is there a setting that would have turn on automatically when it starts?
Love it!

By Nick D. Name (Pcmac user)

I LOVE the way it reproduces the look as well as the action of the calculator. It just wouldn’t be the same without emulating the case, the ports everything. That is for this final but critical extra touch.
Awesome!

I used an HP-41c for years in engineering. This now is far more convenient and true to the original. Developer is also very responsive.
