Lock ideas away, revisit them with fresh eyes.
Capsule lets you capture ideas the instant they strike — as text, photos, or voice notes — and then locks them away until a review window you choose. When the window opens, you revisit everything with fresh perspective, then keep, group, or clear it. Everything is encrypted and stays on your device.
1. Set your daily unlock time and how long the review window stays open, in Settings.
2. Throughout the day, drop in ideas — text, images, or audio.
3. When your window opens, unlock with Face ID and review what you captured.
Yes. Capsule collects nothing and sends nothing off your device. Your content is encrypted at rest with a key held only in your device's Secure Enclave. See our Privacy Policy.
Can I open a capsule early? The whole point is the wait — capsules open on the schedule you set. A one-time grace check is available if you miss a window.
What happens to my items if I update the app? They stay on your device and remain available.
Do I need an account? No. There are no accounts and no sign-in.
