Review of HeadSpin
During a release check, I liked running automated tests on real devices and seeing performance data shaped into experience insights; for QA work that made results easier to interpret across mobile and browser apps, while giving our team something useful to review before changes moved further through the development cycle, and the real device angle mattered to me.
I still wanted clearer answers on connections to our existing tools, admin control over setup, and getting data back out; those are practical checks for an implementation owner, and I would settle them before expanding use beyond QA.
