Read full description

The Sea Levels Project was born out of a love for the environment, a concern over inaction, and a lack of simple to use educational tools. Almost all scientists agree that the global climate is changing, and that sea levels are rising, with an increase in the rate of rise very likely to be caused by humans. When it comes to action it is of no consequence whether the cause of climate change is man-made or natural - it still poses an increasing threat to humanity.  We believe that education is an essential step for us as a species to find a solution. Whilst no mobile application could ever hope provide an answer we can help by providing an informational tool.

Verdict

The call

The clearest difference is in-app purchases: SeaLevels at none against Brilliant's 19. SeaLevels also leads on ads (none vs shown) and review sentiment (100% vs 79%). Brilliant's advantage is rating (4.7 vs 4.3) and update cadence (weekly vs every 7 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Brilliant sells 16 in-app purchases, starting at $19.99 per month. SeaLevels asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Brilliant holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Brilliant has 33K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 79% of Brilliant's written reviews are positive against 100% of SeaLevels's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Brilliant ships an update weekly, SeaLevels every 7 months. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
