There is no store download for most players. OnlySpins runs as a responsive website, so a mobile browser gives you the whole lobby, the sportsbook and your wallet with nothing to install. That matters more here than at most casinos, because a 350% welcome match commits you to a long run of play, and long runs are finished in short bursts on a phone rather than in one sitting at a desk.
Both routes load the same site. The difference is only how you reach it and how it behaves once open.
Opening the site in Safari or Chrome keeps the browser furniture on screen — address bar, tabs, the back gesture — and costs no storage at all. Adding it to the home screen saves a shortcut that launches full screen with its own icon, which looks and feels like an installed app and removes the address bar from the top of the display. Neither version needs updating: changes go live on the server and everyone gets them on the next load.
The steps differ slightly by platform, and on iOS the option only appears in Safari.

Slots are light on data. A game loads its graphics once, caches them, and after that exchanges only small messages carrying the result of each round, so a long session on slots uses far less data than most people expect.
Live dealer tables are different: they are video, and they consume data at roughly the rate of watching a video stream. On a metered plan, a table session is the thing to watch, not a slots session. Video also drives battery use, so plan for a charger if a live run is going to be long.
Dropped signals are handled server-side. A round interrupted mid-spin is settled on the operator's systems and the outcome appears when the connection returns, so a lost bar of reception does not cost you a stake.
Very little functionally, but a few things are genuinely harder on a small screen. Comparing several sportsbook markets side by side takes more scrolling. Bonus terms and the wagering progress figure are usually a menu deeper than on desktop, which matters when a stake cap applies. And multi-table live play is impractical on a phone.
If you are working through a large match bonus on mobile, check two things in the first session: that you can find your remaining wagering total without hunting for it, and that the stake you have set is comfortably below the maximum permitted while bonus funds are active. Both are easier to get wrong with a thumb than with a mouse.
Not for most players. The mobile site covers everything, and Add to Home Screen gives you an icon that launches it full screen.
Only the shortcut itself. Game assets are cached by the browser as normal and can be cleared like any other site data.
Yes. The cashier is fully available on mobile, including card, e-wallet and crypto methods, with the same limits as desktop.
No. One account and one balance cover desktop, mobile and the sportsbook, so a bonus in progress follows you between devices.
The round is settled on the server. Reopen the game and the result will be there, with your balance already adjusted.
It works, but it is a video stream. On a limited data plan, save live tables for a wireless connection and keep slots for mobile data.
