Best AnswerHello @S-FB welcome,
Great question....you will not lose data if you uninstall and reinstall your Fitbit App. Most Fitbit devices record detailed minute-by-minute data for 7 days. (Fitbit Alta records minute-by-minute datafor five days). Fitbit devices can store daily totals for up to 30 days. So your perfectly safe as long as you haven’t gone longer then those day’s stated. 😉
