# Interference vs Flipbook

The clearest difference is review sentiment: Interference at 100% against Flipbook's 13%. Interference also leads on price (Free vs $2.99) and rating (5.0 vs 2.3). Flipbook's advantage is in-app purchases (none vs 1) and ratings volume (10 vs 2). On update cadence, ads and device support there is nothing between them.

Interference is free to download; Flipbook costs $2.99 up front. Interference sells 1 one-off in-app purchase. Flipbook asks for nothing beyond the download.

Interference holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: Flipbook has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Interference's written reviews are positive against 13% of Flipbook's.
