The log you will still be keeping in a month
Logging food is an unusually fragile habit. It works when it takes twenty seconds and collapses when it takes two minutes, which means the deciding features are barcode scanning, a database that knows the shops where you actually shop, and the ability to save a meal you eat every week. Precision matters much less than most apps imply, because an approximate log kept for three months tells you more than a perfect one kept for nine days.
Four different tools with the same name
| What you want | What to look for | What gets in the way |
|---|---|---|
| A rough idea of intake | Fast entry, saved meals, barcode scan | Being asked for grams of everything |
| Detailed nutrition, not just calories | Micronutrients from a verified database | Crowd entries with missing fields |
| A specific way of eating | Built-in handling for that approach | Fighting an app designed for something else |
| Coaching and structure | Lessons, check-ins, a plan | A subscription for content you skip |
| Just the shopping side | Ingredient lists and label scanning | A full diary you did not want |
| Nothing shared anywhere | Offline storage, no account | Social feeds and streaks |

The trackers
The largest database by a distance, which is the whole argument for it. The trade is a crowded interface and more of the useful features behind a subscription than there used to be.
A generous free tier with barcode scanning and a clean diary. The usual first recommendation for someone who does not want to pay anything.
Fast entry and a pleasant design, which sounds trivial and is the reason people keep using it past the second week.
Lifesum: recipe suggestions alongside the diary, so it doubles as a source of meals rather than only a record of them.
The one for detailed nutrition. Verified entries and full micronutrients, which matters if you care about iron or vitamin D rather than calories alone.
Lose It: quick photo and barcode logging with a simple weekly view. Long established and undramatic.
MyNetDiary: well rated, with sensible defaults and a diary that does not require configuration before the first meal.
MacroFactor: adjusts its own targets from your weight trend rather than making you recalculate. The most interesting idea on this list if you eat by macros.
Built around low carbohydrate eating, so net carbs are the headline figure instead of buried in a submenu.
Small, offline and blunt, at around 19 MB. No account, no feed, no subscription prompt; a plain diary for a plain purpose.
Another lightweight option focused on macros rather than coaching, useful on an older phone.
Nutracheck: a UK-oriented database, which is the reason to pick it over the American ones if that is where you shop.
Dated, still functional, and free. Worth knowing about when the modern ones feel like too much app for the job.
Behaviour-change lessons rather than a diary, and priced accordingly. Large at roughly 500 MB, and only sensible if you will read the content you are paying for.
Open Food Facts: scan a barcode and see the ingredients and additives from an open database rather than a brand's marketing. A shopping tool, not a diary.
Plans the week and produces the shopping list, which is the half of the problem a diary does not touch.
Making it survive a fortnight
- Save the five meals you actually repeat Breakfast and the two lunches you rotate. After that most days are three taps.
- Scan rather than search The barcode is the fastest entry path in every app here, and the most accurate.
- Log immediately or not at all Reconstructing yesterday produces a fiction. An approximate entry now beats an accurate one never.
- Pick a portion shortcut and stay with it A mug, a handful, half a pack. Consistency between days matters more than accuracy against a scale.
- Look at the week, not the day Daily totals swing for reasons that mean nothing. A weekly average is the only number worth reacting to.
- Turn the streak notifications off The point is information, not a run of unbroken days that you eventually protect by not logging a bad one.
What the number is not
Every figure in these apps is an estimate. Database entries are often crowd-submitted, labels are allowed a margin, and the energy you actually absorb varies. Treating the total as a measurement rather than an approximation is how people end up either despairing or gaming it, and neither produces useful information.
These are record-keeping tools, not medical advice, and this article is not either. If you are managing a condition, pregnant, or working out how to eat around medication, that is a conversation with a professional who can see your actual situation. And if counting has ever tipped into something compulsive for you, a diary is not a neutral tool and it is reasonable to skip this whole category.
Fast entry, saved meals, a barcode scanner and a weekly average. An approximate log you keep beats a precise one you abandon.
Frequently asked questions
Do I have to weigh food?
No, and requiring it is the main reason diaries get abandoned. Weighing helps for a few staples you eat often; estimate the rest consistently and the weekly picture holds up.
Why do two apps give different calories for the same item?
Different databases, different entries, and in crowd-sourced ones simple errors. Pick one app and stay with it, so at least the comparison between your own days is consistent.
Is the free version enough?
Usually, for logging. What sits behind a subscription is generally coaching, detailed reports and exports. Try the free tier for a fortnight before deciding whether the paid part is something you would use.
