# Squid vs Marine Barometer

The clearest difference is review sentiment: Marine Barometer at 78% against Squid's 38%. Marine Barometer also leads on in-app purchases (none vs 8) and iOS requirement (12.0 vs 16.4). Squid's advantage is update cadence (monthly vs every 15 months) and rating (4.8 vs 4.5). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Squid sells 8 in-app purchases, starting at $5.99 per 7 days. Marine Barometer asks for nothing beyond the download.

Squid holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 55 and 33 respectively. Written reviews complicate that: 38% of Squid's written reviews are positive against 78% of Marine Barometer's, so the app with the better star average is not the one people write more warmly about.

Squid ships an update monthly, Marine Barometer every 15 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
