About offside - shake to hello
offside - shake to hello is a social app from OFFSIDE(Seoul) that centres on a simple greeting gesture suggested by its name. The release listed here is version 1.1.3, available as package com.casti.app.
A greeting in your pocket As a social offering, the app is positioned around the idea of saying hello with a shake rather than through a long setup or a busy interface. The title points to a motion-based hello, so users looking for a lightweight way to acknowledge or greet others will find the concept easy to grasp. Because the listing places it in the social category, it sits alongside other apps focused on人际 contact between people.
Getting it running The build requires Android 7.0 or newer, so anyone on that baseline or a more recent device can install it without hunting for an older release. Installation follows the normal path for a package of this kind: fetch the file for com.casti.app, open it, and grant whatever permissions the app asks for during setup.
Size and storage The download weighs 90.9 MB, which is worth checking against your available storage before you begin. That footprint is comparable to many social apps carrying graphics and interface assets, so freeing a little extra room is a sensible precaution if your device is nearly full.
Developer and release OFFSIDE(Seoul) is the developer behind the app, and the current release on this listing is version 1.1.3, dated 2026-10-03. Keeping the app updated ensures you have the latest build the developer has published for this package.
