# QT ECG vs ECG

The clearest difference is ads: QT ECG at none against ECG's shown. ECG's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (12.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

QT ECG ships an update every 2 months, ECG fortnightly. The most recent releases landed on October 15, 2026 and October 27, 2026 respectively.
