# Multiplier vs HipScreen

The clearest difference is monetization model: HipScreen at free against Multiplier's paid. HipScreen also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 83%). Multiplier's advantage is ratings volume (24 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HipScreen holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Multiplier has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 83% of Multiplier's written reviews are positive against 100% of HipScreen's.

Both ship on a similar rhythm, roughly every 6 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
