Roblox Mobile, also known as the names Roblox iOS and Roblox Android, is the mobile application version of the game available to iOS devices, Amazon Kindle devices, and the recent Android devices (Android Ice Cream Sandwich 4.0.3 or later). The application allows purchasing in-game items from the Catalog and, on the iOS and Android versions, enables access to purchase Android-exclusive/iOS-exclusive items, which are typically paid with Google Play Credit/iTunes money, viewing the player's inventory, friends, groups, and messages, purchasing Robux and/or Builders Club memberships with iTunes money, and features a fully-functional 3D client.
Comparison of Roblox mobile and desktop versions
The mobile graphics are very similar to the 2-3 levels on the graphics scale since material textures and dynamic lighting are removed, but still decals, day/night skyboxes and custom skyboxes exist. This is to limit lag (thus possible risks of crashing) on mobile devices, which are weaker than PCs. On mobile devices, the game will not run at full resolution, regardless of device; instead, it will run at quarter resolution with 4x MSAA (multisample anti-aliasing) to reduce stress on the graphics processor.
If a (usually high quality) game has many models, a large and complex map, and/or anything that can increase lag on a mobile device, a warning is put up on the game's page. To allow players to easily access games that load fine on mobile, the game page is formatted to mostly display games with such trait.

Glitches and bugs present
- The old "Roblox is under maintenance" HTML is sometimes present in the Roblox Mobile with the new UI. It also does this bug on the old Roblox with the old UI.
- Sometimes the jump button doesn't appear.
- There is a rare glitch where the jump button becomes "stuck", preventing a player from jumping unless they reset.
- There was a bug where the player could zoom out through everything.
- On some games, there is a bug where the move and jump buttons disappear, so the player is unable to move which will need the player to rejoin the game to fix it.
- Often, the Movement and Camera Mode wouldn't change when changed in settings.
- There is a bug where the player could get logged out of their account.
- Often, the Chat page won't load up.
- A bug when selected Tap to Move, then tap anywhere to move, and unselected Tap to Move by select different mode. This will cause the player to move everytime they tap despite Tap to Move mode is not selected. The player needs to rejoin to fix this.
- One bug is when the player logs out of their account, the player tries to sign back in, the human verification window won’t load up. This can also happen when your chatting in a group, commenting on a t-shirt, pants, shirt, or model.
The mobile app is often criticized for its tendency to drain the battery life of the player's device. It is also criticized due to its glitchiness and tendency to make the player's device heat up rapidly. Until 2016, Roblox Mobile sometimes had ads after you respawn in the map.
- When the app first was released, it was rated 9+ in the App Store and E10+ in Google Play (similar to ESRB ratings). It was somewhat raised to 17+ in 2015, then in 2016, this rating was raised to 12+, presumably due to players making inappropriate games which either contain violence or brief nudity.
