Verdict
The clearest difference is in-app purchases: Level Up at none against Kronos's 10. Level Up also leads on review sentiment (77% vs 62%) and iOS requirement (8.1 vs 15.0). Kronos's advantage is rating (4.7 vs 4.3) and ratings volume (892 vs 14). On price, ads, monetization model and device support 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. Kronos sells 10 in-app purchases, starting at $0.99 per 7 days. Level Up asks for nothing beyond the download.
Kronos holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Kronos has 892 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 77% of Level Up's written reviews are positive against 62% of Kronos's, so the app with the better star average is not the one people write more warmly about.
Level Up ships an update every 2 months, Kronos every 2 weeks. The most recent releases landed on September 29, 2026 and September 26, 2026 respectively.
