NutraSafe vs Lose It

Who Is Lose It?

Lose It is one of the original calorie counting apps, founded in 2008 in Boston, Massachusetts. It has been downloaded over 50 million times and has a genuinely loyal user base, particularly in the United States. The app's core philosophy is simple and effective: set a daily calorie budget based on your weight loss goal, log what you eat, and stay under budget.

In 2022, Lose It was acquired by Ziff Davis (formerly J2 Global), a large media and technology company. The app has continued to develop under new ownership, adding features like Snap It (photo-based food recognition) and expanding its device integrations.

Lose It deserves credit for making calorie counting accessible to millions of people. Its interface is clean, its onboarding is straightforward, and for users who want a focused weight loss tool without extra complexity, it does the job well. It also has a strong social component with group challenges and community features that many users find motivating.

Who Is NutraSafe?

NutraSafe is a UK indie app, built in 2025 with a different starting question: not just "how many calories?" but "what is actually in this food?" It was designed specifically for the UK market, with a database built around British supermarket products and UK nutritional labelling standards.

Where Lose It focuses on calorie counting for weight loss, NutraSafe takes a broader view of food intelligence. It scans for additives and E-numbers, detects all 14 UK allergens as defined by the Food Standards Agency, classifies foods by their ultra-processing level (using the NOVA framework), and tracks 25+ micronutrients alongside standard calories and macros.

NutraSafe is smaller and newer. It does not have Lose It's 50 million downloads or 17 years of history. But it was purpose-built for a UK audience that wants to understand their food at a deeper level than calories alone.

Feature-by-Feature Comparison

A few things stand out from the table. Lose It holds a clear advantage in social features and photo-based food logging. NutraSafe leads in food intelligence features (additives, allergens, NOVA, micronutrients) and UK database coverage. Both offer solid calorie and macro tracking. These are genuinely different apps solving different problems.

Real-World Test: UK Supermarket Products

The most practical test of any food app for UK users is simple: can it find the products you actually buy? We tested both apps with common items from major UK supermarkets.

Tesco Finest Range

NutraSafe recognised Tesco Finest products by barcode scan reliably, showing correct per-100g nutritional information in the UK format. Lose It struggled with several Tesco own-brand items. Some were missing entirely, while others appeared with US nutritional formats or required manual entry. This is not surprising: Tesco is the UK's largest supermarket but has limited presence in the US market that Lose It primarily serves.

Sainsbury's Own-Brand

A similar pattern emerged with Sainsbury's products. NutraSafe's UK-focused database included the own-brand items we tested. Lose It found some branded products that Sainsbury's stocks (like Heinz or Kellogg's) but had gaps in Sainsbury's own-label range, which accounts for a significant portion of what many UK shoppers actually buy.

Aldi Products

Aldi presented the biggest gap. Aldi's own brands (Bramwells, Specially Selected, Nature's Pick) are largely unique to the UK and Ireland. NutraSafe included many of these products. Lose It had very few Aldi own-brand items, which makes sense given that Aldi's UK product range differs substantially from its US counterpart.

For UK users, the database difference matters because own-brand products are what most people buy most often. If you have to manually enter your Tesco Everyday Value beans or your Aldi cereal every time, calorie counting becomes tedious quickly, and tedium is the main reason people stop tracking.

The Food Intelligence Gap

This is where the two apps diverge most significantly. Lose It is a calorie counter. It does that job well. NutraSafe is a food intelligence app that also counts calories. The difference becomes clear when you scan a product and look beyond the calorie number.

E-Number and Additive Scanning

When you scan a product in NutraSafe, it identifies every additive and E-number in the ingredients list. E171 (titanium dioxide)? Flagged, with context about why the European Food Safety Authority (EFSA) concluded it can no longer be considered safe as a food additive. E621 (monosodium glutamate)? Identified, with balanced information rather than scaremongering. Lose It does not scan for additives at all. This is not a criticism of Lose It; it simply was not designed to do this.

Allergen Detection

The UK has 14 allergens that must be declared on food labels, as regulated by the Food Standards Agency. These include the well-known ones (milk, eggs, peanuts, gluten) and less commonly flagged ones like celery, mustard, lupin, and molluscs. NutraSafe scans ingredients and flags all 14. Lose It does not have allergen detection functionality. For the estimated 2 million people in the UK with a diagnosed food allergy (according to Allergy UK), this is a meaningful difference.

Ultra-Processed Food (NOVA) Classification

The NOVA food classification system, developed by researchers at the University of Sao Paulo, groups foods into four categories based on the extent of industrial processing. There is growing evidence, including from the BMJ and UK-based research, linking high consumption of ultra-processed foods to adverse health outcomes. NutraSafe classifies scanned products on the NOVA scale. Lose It does not include NOVA or UPF classification.

Micronutrient Depth

Both apps track some micronutrients, but the depth differs. NutraSafe tracks 25+ vitamins and minerals with data informed by McCance and Widdowson's Composition of Foods, the standard UK food composition reference maintained by Public Health England. Lose It offers micronutrient tracking primarily in its premium tier, drawing from USDA data. For UK users, the reference values and food composition data matter because nutrient content can vary between UK and US versions of similar products.

Pricing Breakdown

Where Lose It Excels

Lose It is a genuinely good app with real strengths. After 17 years of development and 50 million downloads, it has earned its reputation. Here is where it stands out:

• Focused simplicity: Lose It does one thing extremely well. Its calorie tracking interface is clean, fast, and intuitive. There is no feature bloat. You set a calorie budget, log your food, and stay on track. For users who want exactly that, it is hard to beat.
• Social features and challenges: Lose It has a proper community layer. You can join challenges, compete with friends, and share progress. For people who are motivated by social accountability, this is genuinely valuable. NutraSafe does not offer social features.
• Snap It photo recognition: Point your camera at a plate of food and Lose It will attempt to identify what is on it. The accuracy is not perfect, but as a quick-log tool it reduces friction. NutraSafe does not have photo-based food recognition.
• Mature device ecosystem: Lose It integrates with a wide range of fitness trackers, smart scales, and health platforms. Seventeen years of development means broad compatibility.
• Weight loss focus: If your primary goal is losing weight through calorie control, Lose It's entire design is oriented around that outcome. The onboarding sets a weight loss goal, the daily view shows remaining calories, and the app stays out of your way.
• Established US database: For American products, Lose It's database is extensive and well-maintained. US-based users rarely have trouble finding products.

Where NutraSafe Excels

NutraSafe's strengths are in areas that Lose It was not designed to cover. The two apps have surprisingly little overlap in their standout features:

• UK food database: Products from Tesco, Sainsbury's, ASDA, Aldi, Lidl, Waitrose, Morrisons, and other British retailers. Correct per-100g nutritional information in the UK format. This is the single biggest practical advantage for UK users.
• Additive and E-number scanning: Full identification of additives with context from EFSA and FSA guidance. No other mainstream calorie counter offers this.
• Allergen detection: Automatic detection of all 14 UK-regulated allergens. Essential for anyone managing food allergies or intolerances.
• Ultra-processed food awareness: NOVA classification helps users understand the processing level of what they eat, which is increasingly relevant as UK public health bodies pay more attention to ultra-processed food consumption.
• Micronutrient depth: 25+ vitamins and minerals tracked using UK food composition data. Not just "did you get enough vitamin C?" but a comprehensive micronutrient picture.
• Food reaction tracking: A symptom diary linked to your food log, helping you identify patterns between what you eat and how you feel. Useful for people investigating food sensitivities.
• Offline functionality: Full offline support means the app works on the Tube, in supermarkets with poor signal, or anywhere else connectivity is unreliable.
• Intermittent fasting: Built-in fasting timer integrated with the food diary.
• Expiry date tracking: Scan a product and set a use-by date reminder. A small feature, but one that helps reduce food waste.

Our Verdict

The honest summary is that these apps are less direct competitors than they might appear. Lose It is a focused, effective calorie counter. NutraSafe is a broader food intelligence tool. Which one suits you depends on what question you are trying to answer about your diet.

Frequently Asked Questions

Is Lose It available in the UK?

Yes, Lose It is available to download in the UK from both the App Store and Google Play. However, its food database is primarily built around American products. UK users often find that British supermarket own-brand items are missing or listed with US nutritional formats (cups instead of grams, US reference intakes instead of UK NRVs). You can manually add UK products, but this adds friction to daily logging.

Which app has a better UK food database?

NutraSafe has a significantly better UK food database. It includes products from Tesco, Sainsbury's, ASDA, Aldi, Lidl, Waitrose, Morrisons, and other British retailers with correct per-100g nutritional information and UK-format labelling. Lose It's database is strongest for US products and major international brands.

Can I use Lose It for food allergies?

Lose It does not have a dedicated allergen detection feature. It does not scan for or flag the 14 UK allergens (as defined by the Food Standards Agency) when you log foods. NutraSafe includes automatic allergen detection that identifies all 14 regulated UK allergens including celery, mustard, lupin, and molluscs, which are less commonly flagged by US-focused apps.

Is NutraSafe or Lose It cheaper?

The pricing is similar but structured differently. NutraSafe Pro costs £2.99/month or £19.99/year (about £1.67/month on the annual plan). Lose It Premium costs $39.99/year (approximately £2.65/month or £31.75/year at typical exchange rates). NutraSafe's annual plan works out cheaper per month, while Lose It's free tier includes more features than NutraSafe's free tier. Both offer usable free versions.

Can I use both apps together?

Yes, and some users do exactly that. Lose It is excellent for straightforward calorie counting and weight loss tracking with social accountability, while NutraSafe adds a layer of food intelligence: scanning for additives, allergens, and ultra-processed ingredients. If you already use Lose It for calorie tracking and want to understand more about what is actually in your food, NutraSafe complements it well.
