Solid for our team

We rolled this out across the team last quarter and the value for money is strong. The dashboard fits neatly into how we already work, and the API removed a step we used to do by hand. but it has held up under daily use.

Compared a few options

Evaluated this against two competitors. Where it wins: the integrations and it is genuinely easy to set up. On balance the feature set — especially the core workflow — justifies the 5 stars for our use case.

Solid for our team

We rolled this out across the team last quarter and it saves real time. The API fits neatly into how we already work, and the API removed a step we used to do by hand. The mobile experience lags, which is the main caveat, but it has held up under daily use.

Compared a few options

Evaluated this against two competitors. Where it wins: the automation and the value for money is strong. Where it lags: a few rough edges remain. On balance the feature set — especially the integrations — justifies the 4 stars for our use case.
