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.
Zero holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 38% of BigHand's written reviews are positive against 25% of Zero'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 monthly. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
