Lullogram is a quiet place to land when your head is loud. It's a small set of calming tools that live together in one soft, slow app. No feeds, no streaks, no noise. Open it, pick what your body needs right now, and put your phone down feeling a little more settled than when you picked it up. **Soundscapes that you can feel.** Rain, ocean, nightscape, and more, each with gentle haptics tuned to the sound so it hums through your hand as well as your ears. Set a sleep timer and drift. **Breathing and grounding.** Box breathing, 4-7-8, the physiological sigh, and guided grounding like 5-4-3-2-1 and a slow body scan. A calm circle and soft taps lead the pace so you don't have to count. **Fidget toys.** A pocket of small, tactile things to keep your hands busy. A particle sphere you can push around, a dot grid that dissolves under your finger, bouncing balls, a clicker, and more. **Sleep and your energy.** Log how you slept and Lullogram maps your likely energy through the day, from the morning ramp to the afternoon dip to the evening wind down. See your week at a glance, with a gentle sleep debt nudge when you need it. **Routines.** Stitch a soundscape, a breathing technique, and a fidget toy into one wind down or wake up, and play the whole thing in a row. **For the harder moments.** Quiet Cards give you full screen, swipeable phrases for times when words won't come. An SOS routine keeps your people and a calming pattern one tap away, and it works fully offline. **The small stuff that helps.** Medication reminders, a quick mood check-in, an Apple Watch companion, and home screen widgets so your calm tools are always close. Most of Lullogram is free. A few extras sit behind Pro, and you get three free goes on each of them before you decide. A calm corner of your phone, for whenever you need one. terms of use: https://lullogram.app/terms

The hardest part of managing your weight is not knowing when it ends. WeighCast reads your weigh-ins from Apple Health, follows the trend underneath the daily noise, and estimates when you'll reach the target you set — as a range of dates. WHAT IT DOES • Reads your weight history from Apple Health, or lets you add weigh-ins by hand • Fits a trend that ignores the day-to-day swings of water, food and salt • Forecasts when you'll reach your target — always a range, because a single date would be pretending • Marks the milestones along the way • Shows how your rate has changed month by month • Notices when your trend genuinely changes course, and offers to forecast from there • Optionally shows where the healthy BMI range sits for your height • Exports a clean PDF summary Whether you're losing, maintaining or gaining, WeighCast treats your goal the same way: calmly. Gaining is supported deliberately — for people recovering from illness, restoring weight, or gaining on medical advice. WHAT IT WON'T DO No streaks. No badges. No red numbers. No "you could get there faster". Your weight swings day to day — that's water, not failure — so WeighCast never scores you against yesterday, only shows you the trend. A flat week is shown as a flat week, not a defeat. It won't accept a target below the healthy weight range for your height. And it isn't medical advice — if you have a health condition, talk to your doctor before changing how you eat. HONEST ABOUT UNCERTAINTY Your forecast will move as new weigh-ins arrive — sometimes by weeks. That's the estimate improving, not you failing. WeighCast needs about three weeks of weigh-ins before it can show a date at all, and it says so plainly rather than guessing. YOUR DATA STAYS YOURS Everything happens on your phone. No accounts, no servers, no analytics, no tracking. The only things ever written to Apple Health are weigh-ins and a height you typed yourself. Free to use, with no adverts — there never will be. WeighCast works best with a smart scale that syncs to Apple Health — the more often you weigh in, the sooner you see a date — but manual entry works fine too.
