About this app

Second Nature exists to change minds about losing weight.

Our app uses behavioural science to retrain your mind to make healthy choices automatically, so these stick in the long run.

But we don’t just look at what you’re eating and how much you weigh. We also look at your sleep patterns, exercise levels, how you regulate emotions, and other habits that impact the way you might be feeling.

We also pair you with a registered nutritionist who provides one-to-one advice and supports you to build new, healthier habits.

Our app also has hundreds of simple, indulgent recipes as well as daily articles that explain the science of healthy living - so you feel empowered to make changes, rather than just being told what to do.

Britain’s NHS recommends us because their own research suggests we’re twice as effective as other weight-loss programmes. 90% of Trustpilot reviews rate us as ‘excellent’ because 9 out of 10 people lose weight and keep it off, even after 12 months.

We want to make losing weight feel easier; to make it feel second nature.

Not good. It's a clone of Noom as far as I can tell, with some pretty basic weightloss advice cobbled together. Looks like it's gotten feature bloat over the years alas. Comes with an 'advisor' who seemed over worked and not very helpful. Disappointing as I was hoping this would be a useful tool, but it's not better than MyFitness Pal. It also freezes, loses sync, loses data etc. Not great. :(

It does not link (pair with) my smart watch, even though it's a standard Amazfit watch, though the phone links to it without problems. It does not pair with my smart scales, even though my phone links to them. I am not going to buy a new set of scales just to link them to this app. Room for improvement with both of these issues.

Educational but poor on reliability of information, however two years later I'm still using the app and haven't put the weight back on.
