Verdict
The clearest difference is rating: InterFasting at 4.8 against 다이어트신's 4.2. InterFasting also leads on update cadence (every 2 days vs monthly) and review sentiment (88% vs 64%). 다이어트신's advantage is in-app purchases (none vs 3) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
