Looking for accurate clip-on step tracker that syncs with android

Options
I have been using a Fitbit One for years to track my daily steps and recently lost it :( Fitbit no longer makes the "One". I am looking for another clip on device to replace my Fitbit One..does anyone have any suggestions? I am mainly looking for an accurate step count and a device that is rechargeable by USB, and can sync with my phone.(The online dashboard that Fitbit has is great..it allows you to track your data for an extended period of time!) I feel the clip on trackers are more accurate than wrist trackers....has anyone else experienced the same results? Suggestions?
