Both are free to download. FOUR sells 1 one-off in-app purchase and ROAST APP sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
ROAST APP holds the better App Store score, 4.9 against 3.9. That said, the two scores are not equally well evidenced: ROAST APP has 794 ratings behind it against 54, so its average is the more settled of the two. Written reviews complicate that: 53% of FOUR's written reviews are positive against 52% of ROAST APP's, so the app with the better star average is not the one people write more warmly about.
FOUR ships an update monthly, ROAST APP every 6 weeks. The most recent releases landed on October 30, 2026 and October 21, 2026 respectively.
