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.

Verdict

The call

The clearest difference is update cadence: Second Nature at every 2 days against Liva's fortnightly. Second Nature also leads on monetization model (free vs free with in-app purchases) and review sentiment (66% vs 57%). Liva's advantage is rating (4.7 vs 4.3). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Liva holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 57 and 15 respectively. Written reviews complicate that: 66% of Second Nature's written reviews are positive against 57% of Liva's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Second Nature ships an update every 2 days, Liva fortnightly. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
