# Laboratory vs BUNKER PROTOCOL

The clearest difference is review sentiment: Laboratory at 56% against BUNKER PROTOCOL's 0%. Laboratory also leads on ratings volume (42 vs 4). BUNKER PROTOCOL's advantage is in-app purchases (none vs 3) and rating (4.8 vs 4.4). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Laboratory sells 3 one-off in-app purchases. BUNKER PROTOCOL asks for nothing beyond the download.

BUNKER PROTOCOL holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Laboratory has 42 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 56% of Laboratory's written reviews are positive against 0% of BUNKER PROTOCOL's, so the app with the better star average is not the one people write more warmly about.

Laboratory ships an update every 2 weeks, BUNKER PROTOCOL weekly. Both last shipped on October 24, 2026.
