Tune-up is a shop now. Run Sine’s tuning shop shift by shift: customers bring their instruments, you tune them by ear, and the day’s takings decide whether the shop stays open. Between shifts Otto’s van pulls up with tools and odds and ends to buy, regulars come back with their stories, and what you earn buys your way into bigger shops. Every run unlocks instruments, customers and radio stations for the next. A new sound engine. Notes, chords and the band’s parts are made on a thread of their own, so the keys answer faster and nothing stutters while the music plays. Brass instruments play in tune. Faster on every phone. Scenes are drawn in a new way that asks far less of the phone, so changing screens and opening a game is quicker, most of all on older phones. A phone that still struggles gets a Lighter graphics setting under Performance, and the app turns it on by itself when it sees the need. Fixes. The wardrobe no longer flickers on iPhone, and the app now tells us when something goes wrong, so it gets fixed sooner.
