# iSearch Science vs u

The clearest difference is rating: u at 5.0 against iSearch Science's 3.2. iSearch Science's advantage is ratings volume (13 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. iSearch Science sells 8 in-app purchases, starting at $7.99 per month and u sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

u holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: iSearch Science has 13 ratings behind it against 2, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on August 26, 2026 and September 15, 2026 respectively.
