Verdict
The clearest difference is review sentiment: Zero? at 100% against Life's 33%. Zero? also leads on update cadence (every 3 months vs every 39 months) and iOS requirement (8.0 vs 15.0). Life's advantage is rating (4.0 vs 3.3). On price, ratings volume, ads and in-app purchases there is nothing between them.
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.
Life holds the better App Store score, 4.0 against 3.3. Both are backed by a comparable volume of ratings — 4 and 2 respectively. Written reviews complicate that: 100% of Zero?'s written reviews are positive against 33% of Life's, so the app with the better star average is not the one people write more warmly about.
Zero? ships an update every 3 months, Life every 39 months. The most recent releases landed on July 13, 2026 and June 1, 2026 respectively.
