# Polym vs SecondBrain

The clearest difference is review sentiment: SecondBrain at 100% against Polym's 70%. SecondBrain also leads on rating (5.0 vs 4.6) and update cadence (every 3 days vs every 11 days). Polym's advantage is ratings volume (36 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Polym sells 7 in-app purchases, starting at $7.99 per month and SecondBrain sells 3 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

SecondBrain holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Polym has 36 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 70% of Polym's written reviews are positive against 100% of SecondBrain's.

Polym ships an update every 11 days, SecondBrain every 3 days. The most recent releases landed on October 6, 2026 and October 10, 2026 respectively.
