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. Neither carries in-app purchases, so what you see is what you pay.
REEFB holds the better App Store score, 3.0 against 2.0. That said, the two scores are not equally well evidenced: Mobius has 328 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 27% of Mobius's written reviews are positive against 0% of REEFB's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 9, 2026 and October 11, 2026 respectively.
