🧾 Final Verdict
Fitness trackers are a useful tool for increasing activity, enhancing awareness, and supporting healthy behavior—especially at the start.

But they're not magic bullets—accuracy limitations, privacy concerns, mental health impacts, and waning interest matter.
If used mindfully—as part of a broader lifestyle plan centered on intrinsic motivation and well-being—fitness trackers can be worth it. Otherwise, they risk becoming just another discarded gadget.
