Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
MOUND is free to download; Studio Field costs $29.99 up front. MOUND sells 1 one-off in-app purchase and Studio Field sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Studio Field holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 8 and 5 respectively. Written reviews complicate that: 67% of MOUND's written reviews are positive against 63% of Studio Field'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 5 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
