Best weight tracker apps

Simple and stable, people track weight here for years, and the badges and motivation genuinely keep you engaged. Handy for tracking Mounjaro weight loss, and there is a passcode lock.

The paid version only removes ads and does not carry over months of data, so you re-enter it. A full graph is hard to find, and the old passcode protection went missing in one version.

People who want a reliable simple weight diary for the long haul, including alongside GLP-1, and who value privacy and motivation.

Maximum simplicity, just weight and nothing extra, and you do not have to log every day. A passcode hides the number from prying eyes.

You cannot import old data even manually, and the graph shows only a couple of weeks. The goal calculator gave harmful 500-calorie advice, and the lock screen was removed in the new version.

People who just want to log weight and BMI without calories or settings, and who care about keeping the number private.

Easy shot and injection-site logging, motivating progress view, GLP-1 focus, reminders, useful free version for basics

More tools pushed behind the paywall, shots silently fail to log, total data loss when switching Android and iPhone, review prompt after every shot, crashes with a second medication

People on GLP-1 who want a focused injection and weight tracker and will likely pay for pro

Simple and uncluttered, with funny notes like losing five pounds is worth 175 silver coins. Scrolling history and daily weigh-ins over years work well.

The update coarsened the weight step to half a pound and cut the graph range to three months. Some people lost years of history, CSV export crashes the app, and there is no iCloud sync.

People who weigh in daily and love minimalism with a touch of humor, if they can live with a coarse weight step.

Clear trend graphs, easy weight entry, keeps long weight history, size measurements too, motivates coming back to goals

Wipes years of history at once, shaky sync with Apple Health, Withings and watch, explicit ads at top of screen, tiny text, crashes on tab switch

People who want a simple weight logger with strong trend graphs and can back up data elsewhere

Clean tracking with no bloat or ads, no forced signup, strong food and calorie database, custom recipes, keeps you mindful of intake

Nearly empty barcode scanner, small brand database means manual entry, crashes when entering weight, lost login and history, no Apple Health sync

People who want a no-frills manual tracker of food, weight and calories and will build their own food list

The multi-year trend graph, the BMI metric and moderate coin gamification, plus a responsive developer who ships fixes fast.

Watch and phone do not sync with each other, the percentage and goal math is odd, you cannot fix a wrong entry or add historical data, and there is no landscape mode on iPad.

People who weigh in every day and watch the long-term trend rather than a single number.

A clean simple interface, the trend graph and multi-angle progress photos, home-screen widgets, a one-time purchase and real stories of dropping a hundred pounds or more.

Achievements and backup prompts pop up after every weigh-in, notifications shame you for skipping, the plan caps you at two units a week, the promised free turns into a charge, and Health import sometimes breaks.

People who want a visual tracker with progress photos and a one-time payment and are ready to switch off the nagging notifications.

Before-and-after photos in one place genuinely motivate, you see progress with your own eyes. It used to offer up to fifteen measurement fields and a handy CSV export.

The redesign wiped years of measurements and stripped paid Pro back to a subscription. Sync fails, the number of measurements was cut, and photo compare distorts scale.

People who track by photos and measurements rather than weight alone, and who are willing to back up regularly so they do not lose history.

Money on the line as strong motivation, real large payouts, step and weight-loss challenges, built lasting habits, keeps you accountable

Buggy verified weigh-ins and video uploads, confusing and poor bet odds, pushes unhealthy weight-loss targets, hard to cancel with slow support, clunky navigation

People who lose weight best under a money-on-the-line bet and can handle a rough, buggy app

Meal ideas and recipes, barcode scanning, planning calories days ahead, reminders to think about food, real weight loss on the Mediterranean plan

Misleading ads about what the app is, charges after cancellation, extra upsell for promised features, clunky food search, thin food database

People drawn to a Mediterranean-diet food diary who read the billing terms carefully first

It brings back the old colored WW plans cheaper than the original, with a large food database and a points calculator. The weight trend and food diary are handy, and support helps when reached.

After the yearly auto-renewal access to paid features vanishes, and restore purchase does not work. The barcode scanner is weak, points are sometimes absurd, and support is unreachable without logging in.

Fans of the old Weight Watchers points who will tolerate subscription hassle for a cheap alternative.

The cute companion character that praises healthy meals and keeps you going, a working AI food scanner, and real weight loss for some users.

The AI scanner over- and under-estimates calories, the food database is incomplete and you cannot add your own item, macros were pulled from the free version, plus glitches and silent support.

People who value friendly motivation and food logging over precise weight tracking and are willing to double-check calories by hand.

Scanning barcodes and plates, easy food logging, water and fasting tracking, visible weight-loss results, responsive support

Quiz dead-ends on a paywall, exercise tracking costs extra, wrong calorie counts from scans, glitchy food search, charges after cancelling

People who mainly want guided food logging and weight loss and are fine paying a subscription

Teams and shared challenges keep motivation up, it is nice to lose weight with family or coworkers. Food entry is simple, and the leaderboards and chat in a safe circle land well.

No proper auto-sync with Apple Health and scales, so weight must be typed manually. Pro popups and hidden charges at signup, and the weigh-in button and login sometimes break.

Small groups of friends or family who value mutual support and the thrill of competition more than automation accuracy.

Fast and simple to use, clean BMI result with decimals, handy for quick checks, worked ad-free for years

Aggressive pop-up ads during input, fake storage-full and scam pop-ups, no fractional height entry, no Apple Health sync, ignores muscle and sex

People who want a fast BMI check and can tolerate the new ads, or would pay to remove them

Fun and motivating old avatar version, simple food and weight logging, cute goal options, large food database, more interactive than most

Beloved avatar version removed, once-free features moved behind a paywall, no login so data and profile lost, data wiped after updates, broken barcode scanner

People who want a light, playful food diary and can live without account backup or the old avatar

The avatar that slims down with you genuinely motivates, seeing the graph line crawl downward. Simple and visual, tracks weight and body-fat percentage.

The avatar shames and draws extra weight, inclusivity is thin, and it hurts some people. BMI, avatar changes and total lost sit behind a subscription, and ads are intrusive.

People motivated by a visual avatar and graph, with solid self-esteem, who are willing to pay extra for basic features.

Simple and free, you enter weight and add notes, photos and a passcode. The monthly graph motivates, you see the weight going down.

The graph is locked to 7 or 30 days, and you cannot see the full journey despite years of requests. Data suddenly wipes, does not transfer to a new phone, and ads are heavy with no removal option.

People happy with a free simple tracker over short stretches, who back up their data and tolerate ads.

Helpful intermittent-fasting timer and stages, real weight loss, interactive insights, recipes, keeps you honest about food

Charges without consent and refused refunds, free version logs only one food a day, inaccurate freezing food scanner, no dark mode or widgets, heavy paywall

People focused on intermittent fasting who watch billing closely and will pay for the full app

A clean and fast calculator with no popups for some people, handy for figuring BMI and ideal weight. It helps some folks at work every day.

BMI categories are computed wrong, a healthy weight is flagged as overweight and called fat. After updates it got stuck on kilograms, entry breaks, ads are aggressive, and age is ignored.

People who need a quick one-off BMI figure and will double-check the category themselves rather than take the label to heart.

Instant BMI result, very easy to use, clean quick input, handy as a rough check

Wrong healthy ranges label teens obese, dangerously low BMI shown as normal, ignores muscle mass, triggers body-image and ED harm, no sync between devices

Adults who want a quick rough BMI check and know its limits, not teens or anyone recovering from an eating disorder

Everything for GLP-1 in one place, shots, protein, water, side effects and weight trend, no jumping between apps. Those it fits praise the ease and clarity.

Nothing works without a subscription, payment before any action and no trial. Weak food database, one symptom per shot, weight capped at 330 pounds, portion recognition off.

People on GLP-1 who need a single diary for shots and side effects and are willing to pay upfront blind, if their starting weight is under 330 pounds.

People who broke through the paywall mention real weight loss and motivation, some report eight pounds down in three weeks.

The paywall blocks the whole entrance, subscription ads pop over the screen every few seconds, and the pay button sometimes crashes with an error. Teens without a card simply cannot use it.

People ready to pay for an AI coach right away who do not plan to test it for free.

A pleasant look and a positive, supportive tone, simple input, and some teens like the gentle framing that does not pressure the number.

BMI is calculated incorrectly, height is capped and has no decimals, the basic calculator asks for money, and the app congratulates you on gaining a hundred pounds and mislabels a slim person as overweight.

At most people who want a rough weight reference and do not care about accurate BMI.
