Review summary

Users praise GlassWire for effective data usage monitoring with a firewall and strong visuals, plus real-time speeds and a free feature set. However, multiple users report reliability problems, especially with background monitoring and speed data accuracy, and note that performance can decline over time.

Pros

Strong data usage monitoring paired with a capable firewall to block rogue apps.
Excellent visualizations and a clean, intuitive UI.
Real-time transfer speeds and data-usage notifications.
Free to use with valuable features.
Widely regarded as one of the best data usage monitor tools when it works.

Cons

Reliability issues with background operation: the app often stops monitoring in the background and the persistent notification can freeze, requiring a force close.
Speed data unreliability: internet speed data may be missing or stop updating, which can mislead users.
Long-term reliability concerns: after some time, the app may degrade and become imperfect.
