Verdict
The clearest difference is in-app purchases: OneCal Calorie Tracker at none against Calorie Detect's 1. OneCal Calorie Tracker also leads on update cadence (every 9 days vs every 3 weeks). Calorie Detect's advantage is ads (none vs shown) and iOS requirement (10.0 vs 18.6). On price and device support there is nothing between them.
