You have the number. Adding Spinach to the tracker is free - as is every one of the 961 foods here - but the tracker only keeps the last 14 days in view. Premium keeps every week of your log and turns that history into trends: your average fiber per logged day, the days you hit your goal, and how many of the 30 weekly plant groups you have actually eaten. Custom foods and JSON/CSV export are included.
