Diet trackers

8 tools · last verified July 2026

These are the established calorie and macro trackers — mature apps with large food databases, built around manual and barcode logging. Several have added AI features, but logging remains the core of the product rather than an AI showcase.

What matters most here is unglamorous: database accuracy in your region, how fast you can log a repeat meal, and whether the free tier covers what you need. These apps live or die on daily friction.

We're still building out this category. It's here so you can browse everything we've verified, but we're not promoting it in search until it's more complete.

Listed A–Z. We don't rank by payment — nobody can buy a higher position.

Free tier Gold $10.99/month or $4.99/month billed annually ($49.99/year).
