# Crewproof

> Field service software for small trades crews (HVAC, plumbing, electrical, landscaping), built reliability-first. Currently in development; waitlist open. The research the product is based on is published in full.

Crewproof exists because of a measured finding, not a market hunch: across 58 field service applications and 7,682 one-to-three-star reviews, the largest single category of complaint is the software crashing or freezing — not missing features.

## Key findings (July 2026 study)

- Corpus: 7,682 one-to-three-star reviews across 58 field service apps; 6,871 contained a diagnosable complaint. Sources: Apple App Store (4 English storefronts) + Google Play.
- **Reliability (crash, freeze, "doesn't work"): 19.5%** of substantive complaints — the largest theme.
- Missing feature: 11.2%. Billing & cancellation: 8.3%. Customer support: 7.0%. Complexity/onboarding: 6.8%. Price & value: 6.3%. Team & permissions: 5.8%. Performance: 5.0%.
- **Photo & attachment handling: 3.6%** — more than double the offline signal.
- **Offline & connectivity: 1.7%** — much lower than commonly assumed.
- Money complaints (billing 8.3% + price 6.3%) total **14.6%**, the second largest cluster, and skew toward business owners (the buyers). Crash complaints skew toward technicians (the daily users).

## Reliability complaint rate by app (share of substantive low-star reviews)

- Salesforce Field Service: 41.0% (217 reviews)
- Workiz: 34.2% (155)
- ServiceTitan Mobile: 31.9% (596)
- ServiceTitan Field: 27.4% (186)
- Simpro Mobile: 26.1% (111)
- Buildertrend: 20.3% (349)
- Jobber: 19.5% (472)
- Housecall Pro: 13.9% (410)
- Joist: 11.1% (334)

## A hypothesis this study falsified

The study initially concluded that offline-first operation was the opening, based on 29 connectivity complaints across 6 apps. Expanding to 21 apps reduced offline to 2.4%; expanding to 58 apps reduced it to 1.7%. A market-wide signal holds its share as the sample grows; this one shrank, marking it as an artefact of the initial app selection. This correction is published rather than hidden.

## Stated limitations

- 41% of substantive reviews were not matched by the complaint taxonomy; all percentages are floors, not true rates.
- App store reviews over-represent the daily user; buyer voice on G2 and Capterra is not represented.
- The technician-versus-owner split is directional, not proven — 87.6% of reviews were unattributable by pattern matching.
- No recency weighting; some cited failures may already be fixed.
