About this app
Cartridge Hours is a quiet, private way to know exactly how many hours are on every stylus and cartridge in your setup — and when each one is nearing the life you expect from it. Start the timer when the needle drops. Stop it when you're done. Every minute is counted, on the right stylus, automatically. PRECISE LISTENING TIMER A start/stop timer with minute precision, running as a Live Activity on your Lock Screen and in the Dynamic Island — so you can start and stop a session without opening the app. Start hands-free with Siri or the Shortcuts app, too. YOUR WHOLE SETUP, ORGANIZED Turntable → tonearm → cartridge → stylus. Track multiple decks, cartridges, and replacement styli, each with its own accumulated hours. Simple setups stay simple — a main arm and stylus are created for you. KNOW WHEN TO LOOK CLOSER Enter the manufacturer's rated hours for a stylus and Cartridge Hours shows how much of that life you've used, with a calm nudge as you approach it. You enter the rating; the app reports time — it never claims to diagnose stylus condition. EVERYTHING REMEMBERED Log cleaning, alignment, and stylus or cartridge changes. See your listening over the week and month, and keep a running history for every stylus you've owned. PRIVATE BY DESIGN No account. No ads. No servers of ours. Your collection lives on your iPhone and syncs privately across your own devices through iCloud — we can't see it, ever. A considered tool for people who love records and take care of their gear. Nothing louder.
