Hi mabdellatif, welcome to Android Forums!
What device do you have? That way we can help point you in the right direction. I don't believe I've seen a stock inventory app yet... so I'm guessing it's not from a device that I'm particularly familiar with - but we can point you in the right direction.
Carrier and model would be a start, as it could be an app from one of those. For instance, on some Samsung phones you'll have 'S-voice'. One some Verizon devices you have a few of their apps.... Any of this will help us point out the app and hopefully solve your issue.
Enjoy the site,
