Yes. But it has many bugs.
An app with branding and all the customizations is technically not feasible, I guess or requires tons of programmers. Right now: no customizations, no monetization, no branding. All IPS communities sit in one app like TapaTalk. To have an own app for your community only, you would have to go through Google and Apple approval process to add it to their stores. You, not IPS. It costs.
Another question: why do you need mobile app? If it is because of push notifications, they are integrated in 4.6 without mobile app. Any other reason, you would like to have mobile app? 🙂
