# Tense vs KnowLang

The clearest difference is rating: KnowLang at 5.0 against Tense's 4.2. KnowLang also leads on review sentiment (100% vs 64%). Tense's advantage is ratings volume (11 vs 1) and iOS requirement (11.0 vs 14.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Tense sells 3 in-app purchases, starting at $4.49 per month and KnowLang sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

KnowLang holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Tense has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 64% of Tense's written reviews are positive against 100% of KnowLang's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
