After my wife has the UP24 already in use for 10 days, I have now gained me. The bracelet can be worn comfortably, no annoying feeling. Even while sleeping I wear it, even here no impairments. Vorm first use completely load that occurs with accompanying adapter cable (-> USB), charging can be carried out on the PC, or with a power cord, has the USB connector (not supplied) Meanwhile, the free app can be downloaded and installed. The device with a short registration is done quickly, takes less than 5 minutes. There may be other users invited to the team, so you can show each other what success you have, ie how much steps, etc., certain information may also be suppressed. I use it now since yesterday and all day today. It is good to have the bracelet a "Anschubser" Vibrate you will be asked to move back more. The interval, ie after which "rest periods" this memory comes, can be set individually. Entering Meals and drinks to be taken is a bit complicated for me, I assume, however, that this is just habit. The service at the bracelet is simple, 1 button, the offset by single or multiple pressures the band in another state, eg sleep mode, etc. I use the tape with an iPhone and iHealth App. Here may be allowed, whether read and / or write access is to be allowed by UP24. All in all I'm very happy with my UP24 and can recommend it.
