Repeatability Desk groups baseline and follow-up readings with room, position and equipment context. Compare medians and observed spread while keeping exclusions and missing band fits visible. HOW TO USE THE UPGRADE 1. Capture repeated readings with consistent placement and conditions, or inspect clearly labeled examples. Open Desk and identify the session. 2. Add baseline and follow-up readings. Include at least three readings per group for summaries; record a reason for each exclusion. 3. Review medians and observed ranges, save the session and export the CSV with every included and excluded reading. Room capture, saved reading history, detail views, comparison and acoustic planning references remain. Missing band data is no longer filled with synthetic values in measurement reports. WHAT TO KNOW Three to 12 included readings per group for summaries; up to 50 sessions. Band medians need at least three actual band fits. Observed spread is not a confidence interval or proof that treatment caused a change. Device microphones, placement and ambient conditions affect results. Simulator and example readings are labeled and are not acoustic measurements. Envelope contrast is estimated from the capture, not a calibrated independent noise floor or ISO compliance check. iPhone and iPad. No account required.

ScrollStack finds shared content, aligns your screenshots, and removes duplicated overlap, so you can spend less time arranging images and more time sharing what matters. • Automatic stitching Combine 2–12 overlapping screenshots into one continuous image. • Smart photo ordering Select screenshots in any order. ScrollStack compares shared text and images to find their top-to-bottom sequence. Review or rearrange the order whenever you need to. • Add the missing piece Need more overlap? Add a screenshot to fill the gap without starting over. ScrollStack highlights uncertain joins so you know where more content is needed. • Keep the details crisp Export at the original resolution, preserving clear text and image detail.
