How this was measured

The app universe was built by sweeping 30 trade-specific queries against the iTunes Search API — “hvac business software”, “work order management”, “pest control software”, and so on. That returned 495 apps, filtered down to 49 genuine field service tools; job boards, garage-door openers, retail shift-schedulers and consumer lawn apps were removed. Google Play packages were resolved by verifying candidate package names against the store's own detail endpoint, because Play's search silently returns wrong apps.

Reviews rated one to three stars were collected from the Apple App Store across four English storefronts and from Google Play, deduplicated by review ID. Each review was tagged against a 23-theme complaint taxonomy using pattern matching on its title and body. Theme percentages are computed only over substantive reviews — those of 60 characters or more — because a review reading “Terrible” carries a rating but no diagnosable complaint and would otherwise deflate every rate.

Reliability is the whole story

Crashes, freezes and “it doesn't work” account for 19.5% of substantive complaints — more than missing features, and nearly three times the rate of complaints about the software being hard to learn.

It is also universal. This is not one bad vendor dragging an average — every app measured with 100 or more substantive low-star reviews falls between 11% and 41%.

The hypothesis we abandoned

This study began with a different conclusion. An early pass over six apps found 29 complaints about the app failing without signal, and produced a confident thesis: field service software dies where the work happens, and offline-first is the opening.

What happened when the sample grew

Widening the universe from 6 apps to 21 dropped the offline share to 2.4%. Widening it again to 58 apps dropped it to 1.7%. A signal that is genuinely market-wide holds its share as the sample grows. One that shrinks was an artefact of which apps you happened to look at — in this case, Jobber and Housecall Pro, which do have unusually high offline complaint rates (3.1% and 3.3%) relative to everyone else.

We are publishing this because it is the most useful thing in the study. The offline thesis was plausible, well-evidenced at small scale, and wrong.

Photos are the work product

Photo and attachment handling draws 3.6% of complaints — more than double the offline signal — and when connectivity does fail, photos are what breaks most (23.5% of those cases), ahead of invoicing and payment collection (20.2%).

“Needs an option to upload multiple photos from gallery at once, instead of one at a time. Needs ability to remove photos from tasks in case of accidental upload.”

“Often times I'll attempt to upload pictures and it won't do it, OR it'll say it won't upload when it actually did and I end up uploading duplicates.”

That second quote is the offline problem correctly scoped. The failure is not the absence of an offline mode — it is an upload queue that reports a state it isn't in.

Owners complain about money; technicians complain about crashes

Complaints about money — billing, cancellation, and price — total 14.6%, the second largest cluster. They rose sharply when Apple data entered the corpus, which is also where owner-voice reviews concentrate. Crash complaints run the other way, skewing toward the people who were handed the tool rather than the people who bought it.

“As a technician this app is, on average, the worst part of my day.”

The commercial implication is uncomfortable and worth stating plainly: reliability is what the daily user suffers, but money and support are what the buyer talks about. A reliability-first product is a retention argument more than a sales argument.
