Wanted to share this free app with you guys, especially if you weigh yourselves everyday. (btw I'm in no way affiliated with them, I just thought it could be helpful for others)
The app is called Happy Scale. It takes weight fluxuations into account and it's able to give you an approximate true weight. My favourite features are a bit like what MyFitnessPal does, it gives you predictions of your next milestones and when you'll reach your goal weight.
I've only started using it this week so if you're an expert at it, please let me know how it works out for you
