Verdict
The clearest difference is rating: Denoise at 4.8 against Lenstag's 3.0. Denoise also leads on update cadence (every 4 days vs every 3 months) and ratings volume (31 vs 6). Lenstag's advantage is review sentiment (47% vs 38%). On price, ads, in-app purchases and monetization model 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
Both are free to download. Lenstag sells 3 in-app purchases, starting at $2.99 per month and Denoise sells 5 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Denoise holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Denoise has 31 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 47% of Lenstag's written reviews are positive against 38% of Denoise's, so the app with the better star average is not the one people write more warmly about.
Lenstag ships an update every 3 months, Denoise every 4 days. The most recent releases landed on October 16, 2026 and November 1, 2026 respectively.
