Weight tracker
Four different asks hide behind the word 'weight', and the leaders try to cover all four with one app and fail at the seams.
Some people want a simple diary with a trend chart: that's why they love , 'just the weight and a line, nothing extra'. Others come for a quick number and get a label like 'obese', often they're teenagers, and they leave with a new anxiety. A third group runs a course of injections and logs the dose, the site, the side effects, and the weight together (Shotsy). A fourth group is held by a bet or a team.
Everything breaks at three points. First: the history vanishes after an update or a phone switch, and years of records disappear. Second: the chart gives a 30-day window, while what motivates is the whole road from the start. Third: the number shames, fattening avatars and barbed reminders drive people away.
Market overview
The tone is set by narrow shot trackers like Shotsy: realScore 74 with 26 thousand ratings and no traces of inflation, an army of loyalists on one clear task. Highest on honest quality are the simple diaries and , people keep them for ten years. And the mass-market weight-loss apps like Formula dilute their value with motivation that wounds more often than it helps.

The simple diaries (, , WeightDrop) win on ease and a trend chart, people keep them for years. But they lose records in updates and sync poorly between phone, tablet, and watch. s give a number instantly but drown in accuracy disputes, wound teenagers, and slap ads over the input. The shot trackers (Shotsy, ) cover doses and side effects, Shotsy has fierce loyalty. But both hide almost everything behind a paywall and drop data when moving between phones. The bet and group apps (HealthyWage, ) run on the heat of 'scared to lose the money'. But in both the weigh-in itself jams, weight verification and the scale connection glitch. The big diet platforms (Omo, Formula) add food and calories but drag you into complexity and weak food search.
Audience
"Weight tracker" is not one customer. Inside are different people with different jobs, and they pay very differently. First you choose who you build for.
Where the money is
Where users come from
Channels visible right in the reviews: people say themselves how they found the app and why they installed it. This is the niche's distribution.
Store search for a specific feature6
People search not for a weight tracker in general but for the missing piece: progress photos from three angles, weight together with calories, a decent chart. The install goes to the app whose store title and screenshots match that query exactly.
I've been searching for an app that does comparison/progress photos of at least 3 angles finally found this app. The UI is great and it's super easy to use.
I got this app because it said it would track calories as well as steps, but I just got the app and I don't see any options to track calories just to enter my weight so not what I was looking for.
In pairs for accountability5
People lose weight in pairs and teams: with a brother, a coworker, a wife. One person picks the app and pulls the rest in for the shared challenge, so team features turn every user into an acquisition channel.
I really enjoy using this app with my brother. The team function for holding each other accountable is great
I am using this app with a coworker and with family to focus on fitness goals. I like that mean entry is so easy and I love the leaderboards.
Coming back for a new weight-loss attempt3
Weight loss is cyclical: on a new attempt people reinstall the tracker they remember from last time. The return often crashes into features that moved behind a subscription, and that's the moment a competitor's old users are up for grabs.
I used this app a few years ago. It was great! I downloaded it again. Not nearly as good as it was. It says I have to download premium to get better list of foods.
I used to have this app a year ago... And i found it again days ago and now the free version is not so good. And i thought maybe i should get the premium like they advertise but the price is too high
Instagram ads2
Diet trackers buy installs on social media, but both signals in reviews are about deception: they promised one thing, delivered another, and free turned into a charge. The channel exists, trust in it in this niche does not.
I got this app as it was suggested on Instagram and seemed simple enough for me to understand. The description clearly says "FREE for unlimited time!" but less than a week later I was charged $3.99
I signed up because I was under the impression that this was for a resistance band exercise program NOT another diet app... be careful as the advertisement is very misleading.
Honest rating
The same hundred apps in two scoring systems. Switch and watch the storefront star diverge from what people actually write in reviews.
Weight Diary4.9 in store · genuine · 2,566 ratings80our scoreA time-tested simple weight diary with badges and motivation, like levels in a game. You enter the day's weight, keep notes and watch the trend, and many use it for Mounjaro and Ozempic. Its weak spots are honest, the paid version only removes ads and does not migrate months of data automatically, and there is no backup import.
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.
Weight Diary Lite4.8 in store · genuine · 7,049 ratings78our scoreA deliberately simple weight and BMI tracker with no calorie counter and no extra screens. You enter only the day's weight and can skip days. Importing historical data is not supported, and the built-in goal calculator used to lie and suggest eating 500 calories a day, which is dangerous misinformation.
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.
Shotsy GLP-1 Tracker4.8 in store · genuine · 26,205 ratings74our scoreShotsy заточен под GLP-1 и делает главное хорошо, логирует уколы, места инъекций и вес наглядными графиками с напоминаниями. Ввод простой, но бесплатная версия скудна и всё больше функций уходит за подписку. Донимают баги с пропавшими логами уколов и полная потеря истории при переходе с Android на iPhone, данные между платформами не связаны.
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
WeightDrop Weight Loss Tracker4.7 in store · doubtful · 3,832 ratings72our scoreA long-running minimalist weight tracker with cheerful reward notes for pounds lost. You weigh in daily and scroll through history. After a major update the graph started showing only monthly averages, the entry step was coarsened to half a pound, and some people lost years of records moving to the new version.
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.
Monitor Your Weight4.8 in store · genuine · 23,344 ratings63our scoreMonitor Your Weight силён именно в том, для чего его берут, простой ввод веса и наглядные графики тренда, которые мотивируют вернуться к цели. Но всё чаще всплывают тревожные истории, как приложение стирает годы записей разом. Синхронизация с Apple Health, весами Withings и Apple Watch капризна, а свежий больной вопрос, вульгарная реклама поверх экрана.
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
ControlMyWeight4.6 in store · genuine · 24,047 ratings62our scoreControlMyWeight притягивает тех, кто хочет чистый учёт еды, веса и калорий без коучинга, рекламы и обязательной регистрации. Ручной ввод и свои рецепты работают отлично, а вот сканер штрихкодов почти пуст, база брендов мала и приходится вносить продукты руками. Портят впечатление вылеты при вводе веса, потеря истории и то, что нет синхронизации с Apple Health.
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
Weight Tracker — Scelta4.4 in store · genuine · 994 ratings62our scoreA weight tracker built around trend and light gamification with coins and BMI. Daily weigh-ins and a months-long graph genuinely keep many people on track for years. But Apple Watch sync is shaky: entries on the watch and phone live separately, logging weight on the watch is fiddly, and the math around percentages and goals confuses a lot of users.
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.
Weight Monitor, BMI Calculator4.8 in store · doubtful · 664 ratings60our scoreA tidy weight tracker with BMI, a trend graph, progress photos and widgets. Logging weight is simple, and months of history and body shots are clearly visible, with a one-time purchase instead of a subscription. It is spoiled by pushy achievements after every weigh-in and notifications that shame you for skipping, plus shaky Apple Health import after changing phones.
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.
