GoPro, Inc. · Photo & Video
Most complaints are about crashes, broken camera connection and download, removed editor features (duration control, scrubbing) and general sluggishness. Subscription upsells and a paywall add to the anger. Users are partly captive because they own GoPro hardware, but third-party apps can use the Open GoPro API.
Ambient, LLC · Weather
The sharpest recent anger is over paywalling features that used to be free (historical graphs, rain totals, tile reordering), on top of chronic setup and connectivity problems and a dated UI. Users who own the hardware feel squeezed, but a third-party viewer app could use Ambient's public API.
WEBFRONT INNOVATIONS LIMITED · Utilities
Most reviews attack the $15-20/month per-camera subscription, paywalled live view, and billing after cancellation. There are also hardware and connectivity complaints. The app is a companion for proprietary cellular cameras, so it is not a replaceable commodity app.
Designlibro Inc · Lifestyle
The rating collapse comes from firmware and app updates that break device connectivity, server outages, aggressive subscription upsells and poor support. Users can't switch apps, though, because the app is the only controller for Petlibro's own hardware. A competitor would need to build hardware, not just software.
PULSETTO UAB · Health & Fitness
Companion app for a proprietary neurostimulation device; the decline mixes UX-regressing redesigns, bugs, paywalled device features and billing disputes, but owners can't switch apps because only this app controls the hardware.
Garmin International · Navigation
The app is a mandatory companion for Garmin chartplotters, used for chart purchases, map installs and firmware updates. Reviews complain about clunky sync, confusing UX and slow updates, but users are tied to their Garmin hardware and charts. An outside developer cannot replace the device integration or the licensed charts.
Vorwerk, LLC · Food & Drink
The decline comes from a 2025 redesign plus login and sync bugs. Users can't leave, though: the app is the required companion to a $1,500+ Thermomix appliance and its proprietary Cookidoo recipe subscription, so a third-party competitor can't replace it.
