# QRefine vs Japan

The clearest difference is rating: Japan at 4.8 against QRefine's 4.3. Japan also leads on update cadence (weekly vs every 8 months) and ratings volume (16 vs 3). QRefine's advantage is monetization model (ad-supported vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. QRefine sells 3 in-app purchases, starting at $1.99 per month and Japan sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Japan holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Japan has 16 ratings behind it against 3, so its average is the more settled of the two.

QRefine ships an update every 8 months, Japan weekly. The most recent releases landed on September 19, 2026 and July 18, 2026 respectively.
