I downloaded the Outback app and if I go to Settings->Privacy->Photos I see the Outback app and looks like by default its turned on. Seems like a security threat to me.
Access in iOS is never on by default. You have to approve each app individually.<p>You can go in and turn that access off by launching Settings, and tapping through Privacy->Photos and finding the Outback app and switching it to off.<p>While you're there, you may want to review other privacy settings for other apps.
