How this is scored

Weighted mean of the sub-scores, weights re-normalized over whatever is computable (nobody's fixed it 25 · how far above typical 20 · how angry 15 · people in the market 15 · room to enter 15 · willingness to pay 10). Fixed anchors map each count to 0–100: breadth and willingness-to-pay are straight shares; the gap’s heat tops out at 4times the store’s typical rate; anger scores star3 as 0 and star1.5 as 100; reach runs 10⁴ to 10⁷ratings on a log scale; room to enter is one minus the leader’s share of shelf ratings. A factor that cannot be counted is dropped and named — never imputed. The site’s one composite (#115, owner decision 2026-08-15); cited industry benchmarks are never blended in.

“Absolutely awful product. — Absolutely awful product- difficult to set up, tech support is poor.”La Crosse View · 1star · Aug 22, 2026

“Unnecessarily complicated — This feels more like an android app than an iOS app. You can tell things have been translated roughly from Chinese to English without much care - lots of prompts don’t make sense and labels for commands. Do not make sense either. They say you can leave a voicemail on their telephone number and they’ll support and call you back for questions but they text you and tell yo”Elitech iCold · 1star · Aug 20, 2026

“Won’t connect to WiFi — All I did was change our WiFi password. I followed directions to reconnect same as originally connected. Error message is it can’t connect to their server. Tried 4 times. Going to Amazon to buy something easy to setup and that works.”La Crosse View · 1star · Jul 28, 2026

“Waste of time trying — Can’t get the app to connect the device even with the phone connected to a dedicated 2.4g network. What a waste of time and money.”La Crosse View · 1star · Jun 9, 2026

“What happened!? — This app was solid. Now the company just wants you to subscribe to their services. Plus once you do subscribe (as I did for the year) you’re still limited on only 2 people to share with! For my experience despite it only showing one email, I still can’t share my stations I own multiple locations and multiple stations. Why are you limiting me from sharing my own data!?????

What RevenueCat measures across subscription apps

Their report has no category matching cold chain monitoring apps, so only all-category figures are shown — a near-match would be a guess.

the median app barely grows; the tails are extreme
median MRR +5.3% YoY · top decile +306% · bottom decile contracting
the launch flood vs the incumbency moat
~2,000 → 14,700+ new subscription apps per month (Jan 2022 → Jan 2026), yet pre-2020 apps still hold 69% of subscription revenue

How this is counted

Every number is arithmetic over the reviews we hold, re-counted weekly — nothing modelled, nothing scored. Themes come from a frozen pattern classifier rather than a model reading reviews, so the same review always lands in the same bucket. A shelf rate is pooled across every app here; the store rate is the same count across 12,122 apps. A complaint is only called a gap when at least half the shelf carries it and at least 20 reviews are behind it — a problem concentrated in one app is that app’s bug.
