An eerie, uncomfortable horror is creeping from PC over to iOS! "It is a game as much about horror as it is of horror" - Rock Paper Shotgun "Knock-Knock is a gorgeous survival horror game with more style than sense" - IGN "One of the most fascinating and even endearing gaming experiences I’ve had in ages" - GameFront *** Three generations of Lodgers have occupied the cabin, but lately, the walls seem to undulate, skittering unknowns shift in the darkness, and an unruly growl seeps from the attic. Are they hallucinations pecking at the insomnia-afflicted Lodger, or the gnarled remnants of a darker secret? The woods finally give in to the nightfall, and the dreadful things come out to play. Survive the night while maintaining the dilapidated cabin and preventing the threadbare sanity of the Lodger from unraveling completely. Hide from the grotesque intruders peering from the gloom and seek out the key to ending the Lodger's ordeal. Features: - A game of survival and troubling madness. - Hide from the invading creatures. - Fix the lights and keep the cabin rooms repaired to ward off evil. - Survive the night with your sanity intact. - Solve the mystery of the Lodgers nightmare.

Verdict

The call

The clearest difference is price: Raider at Free against Knock's $0.99. Raider also leads on update cadence (every 9 days vs every 28 months). Knock's advantage is rating (4.7 vs 4.4) and ratings volume (180 vs 27). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Raider is free to download; Knock costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Knock holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Knock has 180 ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 75% of Knock's written reviews are positive against 78% of Raider's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Knock ships an update every 28 months, Raider every 9 days. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
