Just tested the new feature and the first impressions are great! 🚀 Prompt:

Build Kaysia Timer, a polished, working mobile timer app for iPhone 14 Pro. Use your supported mobile stack. All UI copy must be US English. Implement the app, including persistent state and working controls.

DESIGN Light theme only, including when the phone uses Dark Mode. Background #F5F8FC, pale blue surfaces #E3ECF8, dark navy text #192D4A, secondary text #526581, dividers #C7D5E7, primary buttons #315AB7 with white text. Use Newsreader serif for “Kaysia,” page titles and large countdown digits. Use the platform sans serif for controls and body text. Countdown 102px, titles 40px, wordmark 31px, body 17px, buttons 16px medium, metadata 13px. Use tabular digits. Use 24px page margins and generous spacing. Buttons should be compact rounded capsules with at least 44px touch targets. Saved timers are plain rows separated by fine lines. The main visual is a large apricot glass hourglass mascot against a pale blue architectural shape aligned right, with a strongly rounded top-left corner. Give the mascot roughly 260px of height. Keep the layout airy and asymmetrical.

ATTACHED PNG ASSETS Preserve their transparent backgrounds and proportions. kaysia-wave.png: ready screen. kaysia-think.png: timer creation. kaysia-idle.png: running timer. kaysia-sleep.png: paused timer. kaysia-celebrate.png: finished timer. kaysia-blink.png and kaysia-love.png: optional brief tap reactions. Use these exact images. Add subtle floating and state transitions. Respect Reduce Motion. When paused, lower and flatten the pale blue stage over 240ms, like a resting shelf.

FIVE STATES

Ready: “Kaysia” header, add button, waving mascot, “No timers running,” “Saved timers,” and “New timer.”

New timer: “Cancel,” title, thinking mascot, Hours/Minutes/Seconds selectors, Name field with “e.g. Tea,” quick choices 5/15/30/60 min, and “Start.”

Running: timer name, large MM:SS countdown (include hours when needed), “Running,” mascot, “Pause,” “New timer,” saved timers.

Paused: frozen remaining time, “Paused,” sleeping mascot, “Resume.”

Finished: “00:00,” “Time is up,” celebrating mascot, “Stop” and “+5 min.”

BEHAVIOR Persist named presets. Initially offer Tea 5 min, Laundry 35 min and Break 15 min. Support at least two simultaneous independent timers. Show selectable name/time chips to switch between them. Pause, resume, Stop and +5 min affect only the selected timer. Use stored deadlines so backgrounding or reopening never causes countdown drift. Persist paused remaining time. Reject zero duration and prevent duplicate starts.

IOS Where supported, implement AlarmKit alarms, Lock Screen countdowns and Dynamic Island. Alarms must work while locked with Silent Mode and Focus. Reconcile system Stop and +5 min with app state. Use readable monochrome system controls where customization permits. If native APIs are unavailable, explain the limitation in your delivery notes. Never simulate successful integration.

CHECK Test two timers, independent pause/resume, restart persistence and isolated Stop/+5 min. Check small screens, large text and Reduce Motion. Keep copy concise and show contextual errors only when an operation fails.
