Simple Review (2026)
AI-coached fasting timer + photo meal logging in one polished app.
Simple is the most ambitious recent entrant in the fasting category — and the only one trying to combine fasting timing with nutrition tracking in a single polished app.
What Simple does well
Combining fasting + photo nutrition in one place is a real convenience. The fasting timer is reliable and the AI coach’s nudges hit the right notes for most users.
What Simple doesn’t do well
The photo nutrition accuracy trails Welling noticeably. The full $79.99/year price is steep when Zero is free for the timer and Welling at $9.99/month is better for nutrition.
Should you use Simple?
If the convenience of one app matters more than peak accuracy in either function — and you can find the promotional pricing — Simple is a fine pick. Otherwise, Zero + Welling is the more rigorous combo. See the fasting rankings for full context.

What users are saying
"Bought during a $40 promo — worth it for the combination, but I still log most meals in Welling separately."
