Cut Through Daily Scale Noise.
Track Your True Progress.

Why Raw Weight Lies — And How Moving Averages Heal It.
Your body is not a static machine. Glycogen binds 3–4 grams of water per gram of carbohydrate; restaurant sodium triggers temporary water retention; muscle micro-tears from workouts hold fluid. The scale measures all of this—not just body fat.
14-Day Rolling Smoothing Engine
Instead of judging yourself on a single spike, Weight Loss Tracker! calculates a rolling 14-day moving average that absorbs gaps and weekend water bounces. With intuitive Week (7d), Month (30d), 3 Months (90d), and All-Time chart filters, your true direction remains unmistakable.
10 Milestone Stages & Confetti Celebrations
Staring at a distant goal causes burnout before you begin. The app automatically segments your journey into 10 achievable milestone stages (each 10% of your total journey, with standard 5 lb, 2 kg, or 0.5 st steps), rewarding every victory with joyful haptic animations and confetti.

Frequently Asked Questions
Everything you need to know about moving averages, Apple Watch logging, widgets, privacy, and tracking your weight with kindness.
Why does my scale weight fluctuate every day, and how does Weight Loss Tracker! fix it?
Daily weight fluctuates by 2 to 5 pounds due to hydration, glycogen storage, sodium intake, digestion, and exercise-induced inflammation. Weight Loss Tracker! applies a 14-day rolling moving average engine with 7-day, 30-day, 90-day, and all-time chart views to smooth out temporary noise and reveal your true rate of fat loss or gain.
Can I log weigh-ins directly from my Apple Watch?
Yes! Weight Loss Tracker! includes a native Apple Watch app with standalone logging. You can dial your weight using the Digital Crown with tactile haptic feedback and tap to save. It works independently from your iPhone and syncs seamlessly via WatchConnectivity and private iCloud snapshots. You can also add complications to your favorite watch faces.
How do Lock Screen and Home Screen widgets work, and is my weight private?
The app includes Small, Medium, and Large Home Screen widgets, as well as Lock Screen circular gauge and rectangular summary widgets. For privacy, Settings > Widgets includes a "Show weight on Lock Screen" toggle: when turned off, your raw weight number remains concealed on your Lock Screen until you unlock your phone.
How does Weight Loss Tracker! differ from Happy Scale or MyFitnessPal?
Unlike MyFitnessPal, Weight Loss Tracker! focuses purely on mindful weight progression without forced calorie counting, food logging fatigue, or intrusive ads. Compared to Happy Scale, it provides a native Apple ecosystem experience across iPhone, iPad, Mac, and Apple Watch with SwiftData, 17 dynamic themes including Stealth, native Apple Health export, Face ID security lock, and interactive widgets.
Can I customize and reorder the cards on my dashboard?
Yes. In Settings > Dashboard, you can drag and drop all five primary cards (Milestones, Progress Chart, Goal Progress, Forecast, and BMI) into whichever order suits your routine, or hide cards you don't need.
What is the built-in Weight Tracking Guide?
Designed to cultivate a supportive relationship with the scale, the app includes an evidence-based 7-lesson guide directly in Settings covering weigh-in rhythms, trend interpretation, contextual notes, and a healthy mindset with interactive visualizers.
Can I test out the features before entering weeks of personal data?
Yes! In Settings > Example Profiles, you can instantly load realistic pre-built sample profiles (such as Maya Ellis on a steady weight loss journey, a maintenance profile, or a muscle gain profile) to explore interactive charts, milestone rings, and forecast models right away.
Does the app require an internet connection or account creation?
No. You never have to create an account, register an email, or log into a third-party server. All data is saved directly on your device in an encrypted SwiftData sandbox and syncs seamlessly across your Apple devices using your private Apple iCloud account.
How does Apple HealthKit integration work?
When enabled in Settings, Weight Loss Tracker! automatically exports your new and edited weigh-ins directly to Apple Health using HKQuantityTypeIdentifierBodyMass. To preserve your privacy, the app does not read outside health data, ensuring your weight records remain under your control.
Can I use Weight Loss Tracker! to maintain weight or gain weight?
Yes. Weight Loss Tracker! supports three distinct Goal Modes: Lose Weight, Maintain Weight, and Gain Weight. In Maintenance Mode, the app introduces a configurable buffer cushion (such as ±3 lbs) so you can monitor your stability without obsessing over minor daily deviations.
Is Weight Loss Tracker! free to use?
Yes. Weight Loss Tracker! provides full, unrestricted access to every feature—including daily logging, the interactive dial, all 17 theme colors, Apple Watch companion app, widgets, private iCloud sync, Face ID lock, CSV export/import, and all six dashboard cards—for up to 50 logbook entries.
