WHY STEADFAST? Most fasting apps have expanded into calorie counters, meal loggers, AI coaches, and social networks — then locked basic features behind $70-80/year subscriptions.

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. Steadfast sells 2 in-app purchases, starting at $3.99 per month and Ayuno sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Steadfast against 5.0 for Ayuno. That said, the two scores are not equally well evidenced: Steadfast has 7 ratings behind it against 1, so its average is the more settled of the two.
