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. Download the app and sign up today to start your journey! Second Nature uses Apple HealthKit to integrate your phone's step data to help you set goals. ## Key features - Behavioral science approach - Personalized nutritionist support - Holistic habit tracking (sleep, exercise, emotions) - Healthy recipe library - Daily educational articles - Apple HealthKit integration ## Recent user reviews (10 of 102) All indexed reviews: https://appshunter.io/ios/app/second-nature/id885435960/reviews.md ### 5/5 — Great, easy to use and it’s already WORKING for me!!! *2026-06-12* After a pre-diabetic blood result I opted to use Second Nature to support the changes I want to make to get back in a healthy range. First, it’s really easy and quick to use. Short check-in every day (when I can) to read or listen to solid advice backed by medical science and nutritional expertise. With only small changes, without any whiff of awful grey, drab diets. I have a nutritionist on hand to answer any questions and get encouragement - so crucial for staying the course. You have to be open to it though, and engage. So many of us are in the same boat and just want to be healthier but we could never do it ‘alone’. I received a set of Bluetooth scales that automatically updates my weight. Been on Second Nature programme for 4 weeks and so far lost about a pound or two a week with literally NO effort other than to listen to advice and give it a go. Well done to the small but mighty team at Second Nature ⭐️⚡️🐝💛 ### 5/5 — Great educational tool *2026-06-08* This programme of habit change was initially difficult, particularly around planning, preparing and cooking some of the meals. However, once I got into it I found it easy. I was able to adapt recipes with ingredients I had and not worry if I was missing a herb or particular ingredient. The programme has taught me so much about different ways to look after yourself physically and mentally. The changing of your habits is the prize, any weight loss is a bonus. I would highly recommend this programme. ### 4/5 — Weight loss journey *2026-06-01, version 6.56.6* Have started eating more healthily and doing more exercise Hardly eat any bread or potatoes and feel much better for it xx ### 5/5 — Great and holistic program *2026-04-21, version 6.53.0* I was diagnosed as pre- diabetic 2 years ago and recommended this program by my GP. Whilst I did not follow it 100%- I actually did not wish to lose weight, although I did, so had to balance my intake of carbs a bit. However, it drastically changed my eating habits re sweet things etc, so I am now in the "green zone" as far as the pre-diabetes is concerned. No mire craving that afternoon biscuit ...Highly recommended! ### 5/5 — Second Nature Supportive *2026-04-06, version 6.51.0* The Second Nature program and app are are great way to feel supported and to reach your goals. It provides a broad range of tools to create habits, reduce weight and all whilst feeling you are being supported. Well worth getting involved with Second Nature. ### 5/5 — Very good but frustrating *2026-03-27, version 6.49.0* I would have given 5 stars but for the irritating connection between Apple health and the tracking function. The steps work OK but OMIG the sleep tracker drives me mad! It double counts my sleep hours no matter what I do. I ve tried disconnecting sleep sync, erasing errors, adding manually but whatever I do it immediately reinstates weeks of double counting. I know it’s only one part but it’s ruining my experience ### 1/5 — Susan Glegg *2026-03-16, version 6.48.0* Too complicated to navigate ### 5/5 — Review of Second Nature *2026-02-28, version 6.48.0* Superb course - well constructed and professionally delivered by experienced health and nutrition experts ### 5/5 — An app that actually works!! *2026-02-20* I signed up to this program nearly three weeks ago. I love the fact that when I’m not up to exercising I can do them when I’m able, so not missing out as I did when I went to classes. Love the fact that when even reading is an effort I can listen to articles instead, so interesting. Group chat - no pressure and great to hear new ideas from others. On the whole fantastic would highly recommend this app ( Second Nature). ### 1/5 — Download app? Excuse me? *2026-01-18, version 6.46.3* It’s a set of scales… why on earth do I NEED an app, an account, access to my details, my blood, my first borns soul to use them and change the settings? Get a grip. Can’t even login anonymously and change the settings then delete the stupid app; it just says there’s no account with this email — yea well done, I’m literally trying to make one. Good job I got these for free from a relative… who got them from her doctor for a medical issue… they too found them infuriating, hence why I now have some scales that read in pounds only, because reasons? I’m never going to look at this again, even if I get a developer response. If you’re the developer and I’m missing an obvious point here then that’s a product issue, not a consumer one; you should probability address that. ## Frequently asked questions about Second Nature ### What does Second Nature do?
