About

Lettest

Features
Read full description

Lettest is a weight tracker that wants you to win. Open the app and you see one thing: an ambient, living orb that pulses in colour and rhythm to reflect how you're tracking against your goal. It's calming when you're on course, gently warm when you've drifted, and quietly fades when you've been away too long. No stickers, no streak guilt, no cluttered dashboards — just a feeling of how things are going, and a beautiful chart of how things have gone. Logging is one tap. Most days you won't even need to log: if you have a smart scale connected to Apple Health, your weights flow into Lettest automatically. When you do log manually, the entry sheet pre-fills to your last weight and saves with a satisfying haptic. Your data follows you between iPhone and iPad through iCloud — silently, with no setup. Whatever you log on one device shows up on the other. LETTEST IS DESIGNED TO BE QUIET • No notifications by default. The optional reminder only fires if you haven't logged by a time you choose. • No social features, no leaderboards, no coaching content trying to upsell you. • No analytics, no third-party SDKs. The only network calls Lettest makes are to iCloud and Apple Health, both Apple-native. A LIVING ORB FOR YOUR PROGRESS The orb breathes. Its colour, brightness, and pulse speed reflect how you're tracking against your goal: • Cool blue and steady when you're on course. • Bright cyan and faster when you're ahead. • Warm amber when you've drifted off course. • Dimmed when you've been away. GOALS THAT FIT YOUR LIFE Set a target weight, a target date, a weekly rate — any combination, all optional. If you've added your height, Lettest suggests a healthy target based on a BMI of 22 (mid-range of the WHO healthy band). You can accept it or set your own. PROFILE-AWARE With your height set, Lettest shows your healthy weight range (BMI 18.5–24.9) and uses it to suggest goals. The profile prefills from Apple Health if you've granted access, so you don't type anything you didn't have to. CHARTS THAT TELL THE STORY A clean Swift Charts trend with 7-day rolling average, a dashed goal line, and 1W / 1M / 3M / 1Y / All ranges. Drag along the chart to scrub a date readout. The Y-axis tightens around your data so subtle changes are visible. UNIVERSAL APP iPhone in portrait, iPad in a two-pane layout — orb on the left, chart and recent history on the right. Light and dark themes. Full VoiceOver and Dynamic Type support. PRIVACY-FIRST Lettest stores your data in your private iCloud database. No third party sees it. No analytics. The HealthKit integration only reads the body-mass and body-fat samples you authorize, and writes back the entries you log — nothing else. Your weight history is yours. REQUIREMENTS • iPhone or iPad running iOS / iPadOS 17 or later. • iCloud account (sign in to System Settings → iCloud) for sync. Without iCloud, Lettest stores everything locally and still works. • Apple Health (optional) for automatic weight import from smart scales. Lettest is a calmly-built tool for one quiet daily habit. Weigh in. Watch the orb. Repeat.
