Verdict
The clearest difference is rating: Off at 4.6 against Flashcal+'s 2.3. Off also leads on review sentiment (75% vs 50%) and ratings volume (763 vs 6). Flashcal+'s advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and iOS requirement there is nothing between them.
