Verdict

The call

The clearest difference is ads: Photomath at none against Uknow.AI's shown. Photomath also leads on ratings volume (733K vs 4.1K) and rating (4.8 vs 4.6). Uknow.AI's advantage is review sentiment (78% vs 51%) and update cadence (weekly vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Photomath sells 9 in-app purchases, starting at $5.99 per month and Uknow.AI sells 14 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Photomath holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Photomath has 733K ratings behind it against 4.1K, so its average is the more settled of the two. Written reviews complicate that: 51% of Photomath's written reviews are positive against 78% of Uknow.AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Photomath ships an update monthly, Uknow.AI weekly. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
