# Built With Science+ vs Align

The clearest difference is monetization model: Align at free with in-app purchases against Built With Science+'s subscription. Align also leads on rating (5.0 vs 4.8). Built With Science+'s advantage is update cadence (fortnightly vs every 9 months) and ratings volume (4.1K vs 2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Built With Science+ sells 4 in-app purchases, starting at $29.99 per month and Align sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Align holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Built With Science+ has 4.1K ratings behind it against 2, so its average is the more settled of the two.

Built With Science+ ships an update fortnightly, Align every 9 months. The most recent releases landed on October 3, 2026 and September 7, 2026 respectively.
