What we know

On-device calorie and macro tracker with USDA food search plus local voice and photo logging, published as an installable web app.

The official source was read on 23 September 2026. This page describes what the company publishes, not whether its calorie estimates, food database, or recommendations are accurate.

What is still being researched

A full review will add the same 15-field ledger used on the deeper profiles: free and paid pricing, barcode and photo logging, export, nutrients, integrations, adaptive targets, ownership, and the company's supporting pages. Until then, anything not shown in the overview above should be treated as not verified by this directory.

Change history

We keep this profile under review. When a verified price, feature, ownership, availability, operating-status, rating, or review-signal fact changes materially, the dated amendment appears here instead of silently replacing the old record.

Monitoring active. Official information for OpenCal was last checked on 23 September 2026.

No verified changes have been recorded for this profile yet. A quiet history means we have not found a material change—not that monitoring has stopped.
