# 핏데이 vs InterFasting

The clearest difference is rating: InterFasting at 4.8 against 핏데이's 3.3. InterFasting also leads on update cadence (every 4 days vs every 2 weeks) and ratings volume (354 vs 21). 핏데이's advantage is in-app purchases (none vs 5) and iOS requirement (12.1 vs 15.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. InterFasting sells 5 in-app purchases, starting at $3.99 per month. 핏데이 asks for nothing beyond the download.

InterFasting holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: InterFasting has 354 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 95% of 핏데이's written reviews are positive against 89% of InterFasting's, so the app with the better star average is not the one people write more warmly about.

핏데이 ships an update every 2 weeks, InterFasting every 4 days. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
