Aimed at very young players, the apps continue the simple, touch-driven formula Nintendo has used in prior "Hello" titles.
Both Hello Luigi and Hello Peach let children interact directly with the characters’ faces using the Switch touchscreen.
The apps encourage playful experimentation—stretching features, poking, and spinning the characters—to produce a range of expressions and reactions.
In addition to direct touch interaction, each app includes an on-screen ?
Block menu that allows players to spawn items like a Super Mushroom or Super Star, place pipes, and even add enemies into the scene.
Nintendo’s product overview emphasizes the apps’ suitability for young children: they provide light, tactile gameplay and simple modes such as peekaboo.
The overview explains that users can trigger a peekaboo interaction via the menu, and that Boo may appear as a surprise guest during play.
The company also highlights built-in safeguards: the characters will fall asleep after a period of use to encourage breaks, and parents can disable this automatic rest feature through the gear icon when the application launches.
Finally, Nintendo notes that no internet connection is required after downloading, so both apps are fully playable offline.
Hello Luigi and Hello Peach follow Nintendo’s broader strategy of offering small, accessible experiences optimized for casual, family-oriented use on the Nintendo Switch.
Both titles are available now as free downloads from the Nintendo eShop.
Parents and guardians can download and test the settings at launch to adjust the sleep feature according to their household preferences.
For readers tracking Nintendo’s releases, these apps represent another example of the company tailoring experiences specifically for younger audiences on Switch.
