I need a straightforward mobile application whose single purpose is to buzz at times I specify. The app will let me enter reminders manually, store them locally, and then play a loud, unmistakable buzzer sound when each reminder is due. No voice control, no preset schedules—just a clean screen where I can add, edit, and delete reminder times and short labels. I’m after a polished, glitch-free build that runs on modern smartphones, with an intuitive layout and standard notification permissions so the alert pops even if the phone is locked or the app is in the background. A quick settings panel for volume and repeat interval would be useful, but simplicity is more important than feature bloat. Deliverables: • Fully compiled mobile app (Android, iOS, or a cross-platform package if you prefer) • Source code and build instructions • Brief user guide that shows how to add, edit, and clear reminders • Short test report confirming the buzzer triggers reliably at set times If you already have experience with push notifications, local storage, and sound handling on mobile, this should be a fast win. Let me know which framework you’d use and how soon you can have a first build ready.
