Are you ready to survive the unknown? After a devastating airplane crash, a group of survivors—Jake, Andrea, Miguel, Yumiko, Brave Max the loyal dog, and others—wash ashore on a mysterious tropical island. With no way out and dangers lurking in the shadows, they must band together to stay alive. In Horizon Bound, players will guide the survivors as they explore, build, and uncover the ancient secrets of their new home. Gather food, craft tools, construct shelters, and expand your camp to withstand the island’s harsh challenges. Explore deeper and you’ll meet characters who feel like they walked right out of a storybook: a gentle sea warrior who watches the waves, a pirate captain with more charm than sense, and even a curious alien visitor from the stars. They don’t just offer quests—they bring comfort, surprises, and a sense of connection. And just when your group starts to feel like home, a new discovery shakes everything: a second island riding on the back of a giant sea turtle, waiting beyond the horizon. Repair your ship and escape… but the more you explore, the more it becomes about the people beside you. The meals you share. Brave Max curled up by the fire. The mysteries you solve together. The moments that make you want to stay just a little longer. In Horizon Bound, survival becomes friendship—and adventure becomes something you never want to end. Features - - Cozy Survival: Gather, craft, cook, and build a camp that feels like home. A Story-Rich First Island: Explore beaches, caves, ruins, a silent volcano, and a forgotten shipwreck. - A Magical Second Island: Discover a drifting island carried by a giant ancient turtle. - A Cast You’ll Love: Meet the sea warrior, the cheerful pirate captain, the mysterious visitor—and the iconic Miguel on his lawn-chair

Verdict

The call

The clearest difference is rating: Purify the World at 5.0 against Horizon Bound's 3.6. Purify the World also leads on iOS requirement (13.0 vs 15.0). Horizon Bound's advantage is review sentiment (40% vs 25%) and ratings volume (14 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Purify the World holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Horizon Bound has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Purify the World's written reviews are positive against 40% of Horizon Bound's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Purify the World ships an update every 6 weeks, Horizon Bound every 3 weeks. Both last shipped on October 30, 2026.
