Verdict

The call

The clearest difference is review sentiment: Get Fasting at 100% against Zero's 33%. Get Fasting also leads on iOS requirement (15.0 vs 17.0). Zero's advantage is ratings volume (445K vs 20) and rating (4.8 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month and Get Fasting sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Zero holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 33% of Zero's written reviews are positive against 100% of Get Fasting's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Zero ships an update every 2 weeks, Get Fasting monthly. The most recent releases landed on September 25, 2026 and July 1, 2026 respectively.
