Verdict

The call

The clearest difference is ads: Knowt at none against Noji's shown. Knowt also leads on chart position (#99 vs unranked). On price, rating, review sentiment and ratings volume there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Noji sells 10 in-app purchases, starting at $4.99 per month and Knowt sells 9 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Knowt holds the better App Store score, 4.7 against 4.6. Both are backed by a comparable volume of ratings — 14K and 11K respectively. Written reviews complicate that: 64% of Noji's written reviews are positive against 62% of Knowt's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Noji ships an update every 8 days, Knowt weekly. Both last shipped on November 10, 2026.
