“The Friction Matrix: the Productivity chart's silent giants” is no longer published. We found an error in its central measurement and took it down on 8 September 2026 rather than leave it up.
What was wrong. The brief compared the average of an app's recent written reviews against its lifetime average from Apple's ratings histogram, and read the difference as a recent backlash. Those are two different populations. Across the apps we track, written reviews average 3.18 stars and star ratings average 4.69, an offset that has held for a decade. Measured against each app's own earlier written reviews, the average change is -0.02 stars, with as many apps rising as falling. The decline the brief described was an artefact of the comparison.
The reply findings are unaffected, because they never compared the two populations. We are rebuilding the measurement on a like-for-like baseline and will republish with the method stated in full.
