Zero alternative — fasting plus the entire food side
Zero is the most mature fasting app, now with AI meal logging in Plus. Swoodie keeps the fasting tracker free, lets you follow a partner's fast live and adds recipes, planning and a couples mode.
The bottom line
Zero grew from a fasting timer into a fasting-led wellness tracker — Plus now includes AI photo meal logging with a protein score. But it remains eating-window-first: no recipes, no planning, nothing for the meal when the window opens. Swoodie overlaps on the fasting basics (six protocols, free tracker), adds Fast Together, and covers the cooking-and-couples layer Zero never touches — for $30 less a year.
Zero earned its place as the fasting app — fasting stages, streaks, longevity content, and 445K+ ratings at 4.8 stars. Zero Plus now adds AI photo meal logging with a protein focus, a barcode scanner and sleep, activity and mood logging.
What Zero still skips is everything around the fast: no recipes, no meal planner, no shopping list, and nothing for the meal once the window opens. Swoodie ships six protocols with the tracker free, Fast Together so you and a partner can follow each other's fast live, and the whole food side — 8,000+ recipes, Chef AI, AI meal planning and Swipe Together — at $39.99/year against Zero Plus at $69.99.

Where Zero wins
Zero's fasting experience is the most mature in the category — fasting stages, streaks, insights and longevity coaching refined over nearly a decade, plus sleep, activity and mood logging that Swoodie doesn't attempt. If deep fasting science content is your anchor, Zero has no equal.
