Worked briefly then problems piled up
TweakZen's optimisation app sped up my older phone noticeably for the first week, which is why this is not one star. Then crashes began, battery drain worsened beyond baseline, and the premium features I purchased stopped functioning after an update that never got fixed. Support replies were template responses offering generic troubleshooting. The mixed pattern of reviews here mirrors reality: some devices fine, others worse off than before installing.
