Circadian Rhythm Fasting: Based on the research of Dr. Satchin Panda, the confining caloric consumption to about 12-hour period as people did just a century ago. It helps staving off high cholesterol, diabetes and obesity. Custom Fasting: Setup a custom program to meet your fasting goals. You choose your fasting hours per day, and days per week.

Verdict

The call

The clearest difference is rating: Empty at 4.5 against FastTrack's 4.0. Empty also leads on review sentiment (70% vs 50%) and ratings volume (95 vs 3). FastTrack's advantage is ads (none vs shown) and update cadence (every 2 months vs every 6 months). On price, in-app purchases, monetization model and device support there is nothing between them.
