About EP Calipers

EP Calipers places movable calipers over ECG images. Version 3.11.0, released October 17, 2026, is an “Update for iPhone Duo”, the release notes say; they don’t describe the layout. It follows a change to the code from David Mann that keeps the calibration, interval/rate, mean-rate and QTc controls visible instead of moving them into an overflow menu: the buttons use one row when they fit and two when they don’t.

    App version: Not recorded in this evidence.
