Onney

Onney is a private future-letter time capsule app that helps you write notes to your future self and open them at the right moment.

Create a letter, choose a future opening date, select an envelope style, and optionally attach photos that capture your current mood or memory. Once saved, the letter stays sealed until its opening date, helping you preserve the feeling of the moment without turning it into a regular diary entry.

Onney supports open-day reminders, 7-day and 1-day preview reminders, and quiet hours so your future letters can return at a time that feels right. You can view sealed letters, opened letters, countdowns, and letter details in a simple archive. When a letter is opened, you can add a reflection or write back to your future self with a new capsule.

Onney is designed for personal planning, memory keeping, and quiet self-reflection. It does not focus on social posting or AI chat. Your letters, reminders, envelope choices, and optional photos are organized into a calm time-capsule workflow.
