Based on live market data — Updated this week

Why This Score?

✓ Demand is strong across search and marketplace signals.
⚠ Competing here will require real differentiation, not just volume.
✓ Trend data suggests year-round demand rather than a seasonal spike.
✓ 25 Reddit mentions indicate people are actively talking about this.
✓ 1,141 existing books show real, ongoing demand here.
✓ Monetization is middling here, tracking the same moderate demand-and-competition balance covered above.
✓ Search interest is holding steady right now — encouraging for seasonal stability, but still just one snapshot, not proof of evergreen demand.

Recommendation

Food Diary Nutrition Tracker is workable, but success depends more on execution than in a wide-open niche — a narrower sub-angle or stronger keyword targeting will matter more here than usual.
