Verdict
The clearest difference is review sentiment: Nova Cleaner at 75% against Signal Code's 40%. Nova Cleaner also leads on ratings volume (3.7K vs 105). Signal Code's advantage is ads (none vs shown) and rating (4.6 vs 4.3). On price, update cadence, 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. Nova Cleaner sells 9 in-app purchases, starting at $6.99 per 7 days and Signal Code sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Signal Code holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Nova Cleaner has 3.7K ratings behind it against 105, so its average is the more settled of the two. Written reviews complicate that: 75% of Nova Cleaner's written reviews are positive against 40% of Signal Code's, so the app with the better star average is not the one people write more warmly about.
Nova Cleaner ships an update every 3 weeks, Signal Code every 6 weeks. The most recent releases landed on October 19, 2026 and October 13, 2026 respectively.
