Best Calorie App for Someone Who Has Never Tracked Before
The decision is not about which app has the most features. It is about which app you will actually use for 12 weeks.
What logging this seriously looks like
The typical user who logs 5+ days per week for 12 weeks loses 4–8 lb. Heavier starting weights see more; smaller deficits see less. If you log ad-hoc 2–3 days per week, expect roughly no change — the difference between "tracking" and "tracking enough" is the whole game.
Real annual cost in 2026: Truly-free track-only = £0 (Lose It free, Cronometer free, FatSecret). Solid mid-tier = £24–£60/year (Cronometer Gold £48, Yazio Pro £35, MacroFactor £72). Coaching-included = £150–£300/year (Noom 6-month £159, WW Core £276/year).
The coaching vs DIY split
Weight-loss beginners split roughly into two groups: those who need coaching and accountability (Segment 2a), and those who want a tool and prefer to work alone (Segment 2b).
If you have tried self-directed tracking before and quit within three weeks: the problem is usually not information or willpower. It is that the app gave you a number and left you alone with it. Coaching apps (Noom, WW) address this differently — they provide behavioural curriculum, human coaching, and community.
If you are a first-time tracker who is disciplined and prefers autonomy: a DIY tracker (Lose It!, Cronometer) is the right tool. You do not need to pay for coaching if you will not use it.
Noom — the coaching pick
Noom's psychology-based curriculum covers why you eat past fullness, how stress affects food choices, and how to break the "I'll start Monday" cycle. A 2024 Obesity journal study found Noom users were twice as likely to achieve clinically meaningful weight loss vs self-directed tracking — but only if they engaged with the curriculum, not just the food log.
The price is real: £27/month on the 6-month plan (£159 total). That is £13.25/month more than Lose It! Premium. Whether that premium is worth it depends entirely on whether you will engage with the coaching. Full Noom review →
Lose It! — the DIY pick
The best self-directed option for most beginners. Free barcode scanner, clean UI, 15-minute learning curve. For anyone who does not need hand-holding, Lose It! free is the correct starting point. Upgrade to Premium (£40/year) if the upsell prompts become intolerable or if you want weekly nutrient reports. Full Lose It! review →
