Arcaea’s story is interwoven throughout Main, Side, and Short stories which each focus on individual, playable characters. While separate, they all share the same space: the world of Arcaea. Their reactions to it, and its reactions to them, form an ever-shifting narrative of mystery, sorrow, and bliss. As they explore this heavenly place, follow their steps down paths of glass and grief. --- Follow Arcaea & News: Twitter: http://twitter.com/arcaea_en Facebook: http://facebook.com/arcaeagame

Verdict

The call

The clearest difference is ads: Arcaea at none against Project's shown. Arcaea also leads on update cadence (every 8 days vs monthly) and ratings volume (25K vs 1.5K). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Project sells 18 one-off in-app purchases and Arcaea sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Arcaea holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Arcaea has 25K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews point the same way: 72% of Project's written reviews are positive against 78% of Arcaea's.

UpkeepUpdate frequency

Project ships an update monthly, Arcaea every 8 days. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
