The Largest App on the App Store

A Crown That Barely Fits

Ubisoft's Assassin's Creed Mirage wants six gigabytes off your phone before it'll even let you claim the #1 spot on this board. At 6.0 GB, that install comes in at 1.6 times the median size across the entire top 100, and the gap between the list's top and its bottom (#100, at 3.7 GB) was already stretched thin before Mirage ever showed up.

Sure, most phones can swallow that install without blinking. But it's still a hefty chunk of storage to give up for one game, and from what players who've actually downloaded it are saying, they're not thrilled with the trade.

From the Top, It Drops Fast

Mirage is really in a league of its own here. Everything else in the top 100 caps out at 4.1 GB, a drop that's hard to miss, and that ceiling starts right at #2 with 그랑삼국 from YOOZOO (SINGAPORE) PTE. LTD. and continues at #3 with Lost Light: Weapon Skin Treat from NETEASE INTERACTIVE ENTERTAINMENT PTE. LTD, both sitting at 4.1 GB. NetEase Interactive Entertainment shows up again and again on this list, in fact the developer lands 5 times in the top 100, though Lost Light is the only one we can point to by exact rank.

Then there's GBTopoMap from Right Place Resources, parked at #7 with 4.0 GB. A topographic mapping app rubbing shoulders with gacha RPGs and console ports tells you something: genre has nothing to do with file size on this board. Cram enough offline tile data into a mapping app and it'll balloon like a AAA game engine. What matters isn't what kind of app you built. It's how much you decided to stuff inside it.

A Twelve-Time Crown, Held for Two Days

Assassin's Creed Shadows held the top spot right up until Assassin's Creed Mirage took it over in November 2026. Mirage hadn't even cracked the top ten before this. It skipped straight to #1 with no warmup at all. Of the 113 tracked days, it's only held that #1 position for 2 of them. Over the whole tracked stretch, the crown has swapped hands 12 times, so clearly nothing stays put for long at the top.

The download experience doesn't live up to the download size, though. Across 123 reviews, sentiment on Mirage sits at -0.25 and is still sliding, with players repeatedly flagging crashes, freezes, download failures, and trouble logging into their accounts. Breaking a record for size apparently doesn't come with a matching record for stability.
