Lifesum

Lifesum is a Swedish digital-health company headquartered in central Stockholm, founded in 2013. Its app is a calorie and nutrition tracker with several input methods - photo recognition, voice, manual entry, barcode scanning and quick-track - and breaks meals down into protein, carbs, fats, sugars, fibre and saturated fats. Users pick from diets such as keto, high-protein and Mediterranean and get personalised meal plans, recipes and habit prompts. The app syncs with Apple Watch, Samsung Galaxy Watch and other wearables. A free tier is supplemented by Lifesum Premium (around $7.49/month, $29.99/3 months or $99.99/year, varying by region).
