Grace Liu reviews TV and Android utility apps from the sofa, not from a spec sheet. Her test for any cleaner is the same every time: does it explain itself before it changes anything, does it protect the apps a household uses every day, and does it leave a clean way back?
For Clean Your TV, that test meant walking the full flow on a real phone and a real Google TV: the trust prompt on the TV, the analyse plan with its grouped clean list, the restore point saved before the first change, and the undo route for one app and for everything. The guides on this site are written from that walk, checked against the developer official page, and updated when the official page changes.
Grace also keeps the limits in view. Clean Your TV cannot help Samsung, LG, or Roku sets, and it needs an Android phone and the same Wi-Fi as the TV. A review that hides those limits would send readers down a dead end, so every guide here states them up front.
