Would Energz Gofit or Intex Fitrist work without smart phone?
EnergZ Gofit is compatible with Android 4.3 and higher and bluetooth 4.0

FitRist Band is compatible with Android 4.4 and higher

So it's time for a new phone. If they have a program for your laptop then you might be able to get by but, just get a better phone before buying one of those.
