# TOXBASE vs ECG Builder

The clearest difference is update cadence: ECG Builder at every 2 weeks against TOXBASE's every 6 months. TOXBASE's advantage is iOS requirement (15.5 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. TOXBASE sells 1 one-off in-app purchase and ECG Builder sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

TOXBASE ships an update every 6 months, ECG Builder every 2 weeks. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
