I've made a small app for the company I work at and I'm looking to distribute it. It isn't going to very many people, less than 100. I don't want to use it as a B2B app as then I'd need to setup a server and setup device management. It seems I'm able to distribute promo codes and users can install the app through the app store that way, even though the app is a 'custom app for business'.
Is this a reliable method of distribution?
Will users be able to update?
