Is there any way to distribute ios applications through my own website, not using app store?
I mean is there any way that enables end users to download
You if don't want to upload your files to the already mentioned web services, you can host your IPA in your own computer and distribute over the internet using ngrok and the approach given by jithin.
I've created a server that does exactly that and also is protected by password. You can check it out here:
