> An open study of what people complain about in software they already pay for. 64,871 one-to-three-star reviews across 24 categories of paid software, tagged against a 23-theme complaint taxonomy. Every study states its method, its verdict and its limits.

## Headline findings

- **Payer pressure is the gate.** The share of complaints about money collapses to 0.00 wherever the employer buys the software and the employee uses it, against 0.12–0.16 where the reviewer buys it themselves. A loud corpus is not a market.
- **A thesis that shrinks as the sample grows was never real.** An offline-first thesis for field service went from 29 mentions across 6 apps, to 2.4% at 21 apps, to 1.7% at 58. The actual pain was ordinary crashes (19.5%, universal) and photo handling (3.6%).
- **Reliability dominates almost everywhere**, at 11–41% per app in field service and 14–37% across categories — but it is a retention argument, not a sales one.
- **Some categories cannot be measured this way at all.** Auto repair, veterinary and dental practice management run on Windows desktop software; the app stores hold only tiny companion apps or name collisions.

## Stated limitations

- About 41% of substantive reviews are not matched by the taxonomy, so every percentage is a floor rather than a true rate.
- App-store reviews over-represent the daily user; buyer voice on G2 and Capterra is not represented.
- No recency weighting; some cited failures may already be fixed.
