Does Jailbreak affect Apps?

[maykumah]

I recently jailbroke my ipad and since then my ihealth BP3 monitor hasn't worked. The start button won't trigger everything else works. Does anyone know how to solve this problem. Thanx

Some applications check, then fail to run on Jailbroken devices.

Some apps will break even if they don't specifically check for jailbreaks.

The xcon tweak may help. I had an app that didn't check for jailbreaks but it would break similar to the way the Op's is and the xcon tweak fixed it for me
