Verdict
The clearest difference is ads: Rebel Core at none against FLK Method's shown. Rebel Core also leads on monetization model (ad-supported vs free with in-app purchases) and ratings volume (239 vs 37). FLK Method's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price, rating, review sentiment and update cadence there is nothing between them.
