Happy Scale Alternatives 2026: 7 iPhone Weight Trackers Compared

By The Periscope Team · · Updated · 9 min read

For most people, the best Happy Scale alternative is Periscope: free, with a smoothed trend line, reports with BMI, progress photos with a slider, widgets and Apple Health sync. Weight Diary ($7.99 once) is the closest like-for-like swap, with no account. Weigh In is free and weight-only; Monitor Your Weight has an Apple Watch app.

Key takeaways

  • Happy Scale is still the most established trend-and-prediction tracker on iPhone, with a 4.89 average from 58,067 US ratings as of October 2026, so switching only makes sense if you need something it doesn't offer.
  • Weight Diary and Weigh In keep everything on your phone, and neither asks you to create an account.
  • Happy Scale doesn't list an Apple Watch app; Monitor Your Weight, MacroFactor and Noyoyo all do.
  • Happy Scale's listing and website don't mention progress photos; Periscope adds them for free with a before/after slider, alongside a trend line, reports with BMI and widgets.
  • The easiest way to switch is through Apple Health: turn on Happy Scale's Health export, then turn on Apple Health sync in the new app.

Most people looking for Happy Scale alternatives aren't unhappy with it. It has been on the App Store since 2012, and for a lot of people it's the app that made daily weighing bearable. Shopping around usually comes down to one missing thing: progress photos, widgets, an Apple Watch app, or food tracking in the same place.

A quick disclosure first. This comparison was written by the team that makes Periscope, a free weight tracker for iPhone, and Periscope is one of the apps below. To research it, we went through each app's App Store listing and official site in October 2026. We didn't use every app day to day for weeks, so where a listing or site doesn't say something, we've written "Not stated" instead of guessing. Prices and ratings are from the US App Store and will change. For trackers beyond Happy Scale's neighbors, including calorie counters and smart-scale apps, see our roundup of the best weight tracking apps for iPhone.

Who is Happy Scale best for?

Happy Scale suits people who weigh often and want the app to interpret the numbers for them. Its core is a moving average that smooths out daily swings, with predictions of what you'll weigh in the future, milestone goals and event dates you can aim for. If you want to know why that kind of smoothing matters, our explainer on trend weight walks through it.

Where it's strongest:

  • Maturity. It was first released in July 2012 and was last updated in October 2026. That's 14 years of refinement on one idea.
  • Predictions. Few apps go as far in projecting a goal date from your trend.
  • Track record. A 4.89 average from 58,067 US ratings as of October 2026, the highest count of any dedicated weight tracker we looked at.
  • Privacy. Its privacy policy says health data is stored locally on your device by default, with optional Dropbox sync, and no account is mentioned.

The free version is generous. Happy Scale Deluxe is $1.99 a month, $11.99 a year or $39.99 for lifetime access. If it's doing what you need, our honest advice is to keep it.

Why look for a Happy Scale alternative?

People usually leave for a missing feature rather than a flaw. The verifiable gaps:

  • Progress photos. Not mentioned on Happy Scale's listing or website.
  • Apple Watch. No Watch app in its App Store compatibility list.
  • Food tracking. It doesn't count calories, by design.
  • Some features are paid. A few tools sit behind Deluxe, though the price is modest.

One thing we couldn't settle: widgets. Happy Scale's own listing and site don't mention Home Screen widgets, so we've marked them "Not stated" rather than claim either way.

How we compared

We looked at every app against the same list, using its App Store page and official site or privacy policy:

  1. Price in the US App Store as of October 2026, and what sits behind a paywall.
  2. Account. Whether you have to sign up before you can log a weight.
  3. Where your data lives: on your device, in your own iCloud, or on the developer's servers.
  4. Trend line and predictions, the reason most people use Happy Scale in the first place.
  5. Progress photos, and whether you can compare two.
  6. Widgets, Apple Health and Apple Watch.
  7. Track record: App Store rating, number of ratings and how recently it was updated.

The alternatives, one by one

Periscope: best overall alternative for most people

Best for: Happy Scale users who want progress photos and a trend on their Home Screen, and anyone starting fresh who wants a simple tracker for free.

Periscope is our app, so weigh this section accordingly. If you like Happy Scale's calm trend line, the core will feel familiar: the Reports tab smooths your weigh-ins with a lag-corrected moving average and gives you weekly, monthly and yearly cards with your rate of change, lowest weigh-in, BMI (once you add your height; our BMI calculator shows the healthy range) and an optional goal line. What it adds is the visual side. Each weigh-in can carry up to two photos, and you can drag a before/after slider between any two entries or press Play to animate them, with a body-outline tool to line the two photos up. Home Screen and Lock Screen widgets (iOS 17 or later) keep the trend and goal progress in view. Switching is straightforward: turn on Happy Scale's Health export, and Periscope's Apple Health sync brings those weigh-ins in. It's free, with no ads, subscription or in-app purchases, and it runs on iOS 15.1 or later.

What to know: you create an account with Sign in with Apple. Weights, photos and notes stay on your phone; our server stores your account details (email or Apple ID, and name). Periscope is iPhone only, has no data export, Apple Watch app or sync between devices, and doesn't make goal-date predictions the way Happy Scale does. The Home chart shows your raw weigh-ins; the smoothed trend lives in Reports and the widgets.

Price as of October 2026: free.

Weight Diary: closest like-for-like replacement

Best for: Happy Scale's core idea, with no account and no subscription.

Weight Diary draws a trend line through your daily fluctuations, shows your rate of loss and estimates when you'll reach your target. You can set a custom start date, record body fat and notes, sync weigh-ins from Withings or Fitbit scales, and lock it with Face ID. It has been around since 2011 and holds a 4.88 average from 2,625 ratings as of October 2026.

What to know: there are no progress photos and no Apple Watch app, and it needs iOS 18 or later. There's also a free Weight Diary Lite, but it's a separate app, and its listing doesn't include Apple Health or scale sync.

Where it beats Periscope: no account at all, an iPad version, and backup, import and export built in.

Price as of October 2026: $7.99, once.

Weigh In: best free, weight-only tracker

Best for: logging your weight and nothing else, without paying or signing up.

Weigh In is free with no in-app purchases, and its privacy policy is as short as these get: everything you enter "is stored on your device and is not transmitted anywhere." There's no account. You get a target weight, notes, reminders on a schedule you pick, graphs showing your start, target and average, and CSV import and export. It syncs weigh-ins with Apple Health.

What to know: it's deliberately bare. No photos, no smoothed trend or predictions mentioned, no Apple Watch app, and no iPad version on its App Store page. The developer's site lists iCloud sync as "coming soon". Rating: 4.71 from 620 ratings.

Where it beats Periscope: CSV import and export, and no account.

Price as of October 2026: free.

Monitor Your Weight: best for Apple Watch and smart scales

Best for: people who want to log from the wrist or connect a non-Apple smart scale.

If Happy Scale's missing Watch app is the dealbreaker, this is the most direct fix. Monitor Your Weight runs on iPhone, iPad, Mac and Apple Watch, and supports iOS 13, so it also suits an older phone. Like Happy Scale, it estimates when you'll reach your target; unlike it, it handles several people on one device, connects Garmin, Withings, Aria and WiT scales directly, and lets a doctor or coach view your progress on the web. Body measurements, body fat, a calorie calculator, a PIN lock and full data export are in there too. Rating: 4.83 from 23,732.

What to know: cloud sync is a separate $0.99 purchase and needs a login.

Where it beats Periscope: an Apple Watch app, iPad and Mac versions, multiple profiles and data export.

Price as of October 2026: free; sync $0.99.

Progress: best for body measurements and photos

Best for: tracking your waist, hips, arms and the rest alongside your weight.

Happy Scale is built around one number. Progress (listed on the App Store as "Body Measurements Tracker App") is built around many: 17 standard measurements and up to 10 custom ones, plus body fat, BMI and goals. Front, side and back photos can be compared two at a time. Free users get two-way Apple Health sync, and the listing says data stays on your device and in your own iCloud. It's as old as Happy Scale, dating back to 2012, with a 4.63 average from 9,358 ratings.

What to know: photos are a Pro feature, per the listing's FAQ. A trend line and widgets aren't mentioned, and it needs iOS 18.

Price as of October 2026: free; Pro $3.99 to $5.99 a month, $11.99 to $19.99 a year, or $29.99 lifetime (Apple lists several price points).

MacroFactor: best if you also track food

Best for: counting calories and macros with a trend weight at the center.

MacroFactor smooths your daily weigh-ins into a "Weight Trend" and uses it, along with your food log, to estimate your energy expenditure and adjust your calorie targets. It also has progress photos (front, side and back) with a side-by-side comparison, 21 body metrics, widgets, Apple Health integration, and an Apple Watch app that shows scale and trend weight. Rating: 4.84 from 23,128.

What to know: there's no free tier after the 7-day trial, you need an account, and your data is stored in the developer's cloud. You get the most out of it only if you log food.

Where it beats Periscope: an Apple Watch app and food tracking.

Price as of October 2026: $11.99 a month, $47.99 for six months or $71.99 a year.

Noyoyo: best for GLP-1 medication users

Best for: people on a GLP-1 medication who want shots and weight in one place.

Noyoyo logs GLP-1 doses, injection site rotation and side effects, and puts your actual weight against a predicted trend with projected goal dates. It also tracks 7- and 14-day averages, BMI, body fat, water, sleep, steps and fasting, and has widgets, an Apple Watch app and a community feed. Rating: 4.86, though from only 171 ratings.

What to know: its privacy policy describes accounts created with Sign in with Apple or Google and data stored on its servers. It names Google Analytics, Firebase and Mixpanel, and says it doesn't sell personal data.

Price as of October 2026: free to start; subscriptions range from $3.99 a week to a $99.99 lifetime option.

Which Happy Scale alternative should you pick?

If you want a simple, free tracker and progress photos matter to you, start with Periscope. The trend line and reports cover the numbers, the photo slider and widgets add what Happy Scale's listing doesn't mention, and Apple Health sync brings your weigh-ins across. Look elsewhere if you need export, an Apple Watch app or no account. By need:

  • You want progress photos and a trend line without paying: Periscope.
  • You want the same approach, no subscription and no account: Weight Diary.
  • You want free and nothing but weight: Weigh In.
  • You want an Apple Watch app: Monitor Your Weight, or MacroFactor if you'll also log food.
  • You track tape measurements: Progress.
  • You count calories: MacroFactor.
  • You're on a GLP-1 medication: Noyoyo.
  • Goal-date predictions are what you value most: stay with Happy Scale. Nothing here clearly beats it at that.

A note on any tracker: seeing a trend makes daily weighing calmer for many people, but not for everyone. If weighing or photos make you anxious, or you have a history of disordered eating, it's fine to skip them. The National Eating Disorders Association has support if you need it.

How do you move your weight history out of Happy Scale?

Apple Health is the bridge. In Happy Scale, turn on its Apple Health export (it's opt-in) so your weigh-ins are saved to Health. Then open the new app, turn on Apple Health and allow access to weight. Before deleting anything, scroll back in the new app and confirm your older entries arrived, not just the latest ones.

If you'd rather use a file, Happy Scale's release notes describe CSV export (now including your Logbook notes), and Weigh In can import CSV. Column formats differ between apps, so check a few rows after importing. Periscope doesn't import files; Apple Health sync brings your history in. For permissions and fixing duplicate weigh-ins, see our guide to Apple Health weight tracking. For a closer look at the two apps, read our Periscope vs Happy Scale comparison.

Frequently asked questions

Is there a free app like Happy Scale?

Happy Scale is free to download, with an optional Deluxe upgrade. For an alternative with no in-app purchases at all, Periscope (our app) has a smoothed trend line, reports, progress photos and widgets. Weigh In covers weight logging with a graph and reminders, and Weight Diary Lite is the free version of Weight Diary with its trend line.

Does Happy Scale have progress photos?

Neither its App Store listing nor its website mentions progress photos as of October 2026. Periscope (our app) includes progress photos with a before/after slider for free. Progress and MacroFactor both compare photos side by side, though in both it's a paid feature.

Does Happy Scale work on Apple Watch?

No Apple Watch app appears in Happy Scale's App Store compatibility list. Monitor Your Weight, MacroFactor and Noyoyo each list one.

Which Happy Scale alternatives work without an account?

Weight Diary (the paid version) and Weigh In both keep data on your phone and don't require an account. Periscope also keeps weights and photos on your phone, and uses Sign in with Apple.

How do I move my weight history out of Happy Scale?

Turn on Happy Scale's Apple Health export so your weights are saved to Health, then turn on Apple Health in the new app and allow access to weight. Check afterwards whether your older entries came across, not just the newest ones. Happy Scale can also export a CSV file for apps that import one, such as Weigh In.

Track the trend, not the noise

Periscope is a free weight tracker for iPhone with a smoothed trend line, progress photos and widgets. Your weights and photos stay on your phone.
