Frequently Asked Questions
Is NextWeigh cheaper than Simple?
It depends on the Simple plan. Simple doesn't publish a price list, and its App Store purchases range from $14.99 to $59.99. NextWeigh is $29.95 a month, month to month. Checked November 6, 2026.
Does NextWeigh do intermittent fasting?
NextWeigh isn't a fasting tracker. Your coach builds small daily actions around your goal and schedule. If fasting is part of your plan, tell the coach. See our guide to intermittent fasting for beginners.
Are both AI coaches?
Yes. Simple's coach, Avo, lives inside its app. NextWeigh's AI coach texts you, so there's nothing to open, and people on the NextWeigh team step in when something needs a human.
