Verdict
The clearest difference is ratings volume: HiCoffee at 839 against Decaf AI's 8. HiCoffee also leads on update cadence (every 10 days vs every 6 weeks) and device support (5 vs 2). Decaf AI's advantage is review sentiment (100% vs 82%) and rating (5.0 vs 4.8). 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. HiCoffee sells 3 in-app purchases, starting at $0.99 per month and Decaf AI sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Decaf AI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HiCoffee has 839 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 82% of HiCoffee's written reviews are positive against 100% of Decaf AI's.
HiCoffee ships an update every 10 days, Decaf AI every 6 weeks. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
