Weighly - Your weight, finally understood, with an on-device AI coach

Hey Product Hunt! 👋 I'm the maker behind Weighly, built at GladeX, my small independent studio in Ukraine. Why I built it: every weight tracker I tried showed the raw number, and the raw number lies. You drink more water, eat a salty dinner, sleep badly, and the scale jumps up. Many people see that and give up, even though they're doing everything right. So Weighly is built around one idea: show what the number actually means. ✨ What it does • True weight: a smoothed trend that filters out daily water swings • Goal date forecast from your real pace, with a range for slower and faster weeks • An AI coach you can ask anything ("Why did my weight go up today?"). It runs fully on-device with Apple's Foundation Models, so your data never leaves your iPhone • Plateau help: when your weight holds for two weeks, it explains why and suggests one small step • Progress photos with a before and after slider, intermittent fasting with Live Activities, Apple Watch app and widgets Also inside: water, steps and food from Apple Health, a daily calorie target, BMI and body measurements, optional cycle awareness, streaks and milestones, detailed analytics with a PDF report, iCloud sync, Face ID lock and 13 languages. 🔒 Privacy by design: no account, no ads, no tracking. It works whether you want to lose, maintain or gain weight, and the tone is always kind, never shaming. The AI coach needs a device with Apple Intelligence; everything else works on any supported iPhone. I'd love your honest feedback: what would make you actually stick with a weight tracker? I'll be here all day answering every comment. 🙏
