# Protein Tracker vs Zero

The clearest difference is ads: Protein Tracker at none against Zero's shown. Zero's advantage is update cadence (every 6 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Protein Tracker ships an update every 2 months, Zero every 6 days. The most recent releases landed on October 28, 2026 and October 27, 2026 respectively.
