# InterFasting vs ArcFast

The clearest difference is ads: ArcFast at none against InterFasting's shown. ArcFast also leads on rating (5.0 vs 4.8). InterFasting's advantage is update cadence (every 4 days vs every 6 weeks) and ratings volume (352 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. InterFasting sells 5 in-app purchases, starting at $3.99 per month and ArcFast sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ArcFast holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: InterFasting has 352 ratings behind it against 1, so its average is the more settled of the two.

InterFasting ships an update every 4 days, ArcFast every 6 weeks. The most recent releases landed on October 25, 2026 and October 12, 2026 respectively.
