Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the automation, and support is responsive caught me off guard. The docs could be deeper is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the onboarding — handled better than most — and the value for money is strong. The mobile experience lags is my one real gripe. Worth the time if this is your use case.

Use it every day

Honestly didn't expect to like it this much. The onboarding is exactly what I needed, and the value for money is strong. I do wish a few rough edges remain, but I reach for it almost every day now and it just clicks.

Honestly didn't expect to like it this much. The core workflow is exactly what I needed, and it saves real time. I do wish the docs could be deeper, but I reach for it almost every day now and it just clicks.
