Some things are better when they wait.
Cozy Capsule lets you and the person you love write each other letters that aren't delivered today. A reassuring message waiting for the next time they're missing you at 2am. A photo from this weekend, sealed shut until your next anniversary. A voice memo from you—calmer, warmer, braver than you usually are—saved for the day they need it most.
Pair with the person you love, seal a capsule (words, photos, a voice memo), and choose exactly when it arrives.
— FOR PEOPLE WHO LOVE ACROSS DISTANCE —
If you're in a long-distance relationship, deployed, in different time zones, or just trying to make a long love feel close again, Cozy Capsule was built for you. A capsule that opens at 7am their time, on a morning you knew would be hard, is worth more than a hundred "thinking of you" texts sent in the moment and lost in a feed.
— OPEN WHEN: —
Some capsules shouldn't be tied to a date. Seal one that opens when they're missing you. When they're nervous about a big day. When they need to remember how loved they are. You write the condition. They decide when it's true. The capsule is waiting either way.
— ONE PLAN. BOTH OF YOU. —
Cozy Capsule Pro is one subscription that unlocks Pro for both partners. When you subscribe, your paired partner is automatically upgraded. No second purchase, no second login, no awkward conversation about who pays. Love isn't a per-seat license.
Pro gives both of you unlimited active capsules, so you can layer messages years into the future, stack recurring rituals on top of anniversaries on top of Open Whens, and never have to choose which one to seal next. Free accounts can hold 3 active capsules at a time, which is plenty to fall in love with the app. Pro is for when you're ready to build something that lasts.
— THE WIDGETS —
The home screen widget cycles through photos from your partner with a countdown to your next waiting capsule alongside them. The lock-screen widget keeps it minimal, just the countdown, ticking down to the day the next one arrives. Either way, a small reminder that something good is on its way, from someone who loves you.
— FEATURES —

— PRIVACY —
Photos, voice memos, and messages are stored privately and locked behind delivery rules. Your partner cannot read a sealed capsule before its time. Once a capsule is sealed it stays sealed, which is the whole point. If you ever want to step back, you can unlink from your partner at any time and everything between the two of you is removed. You can delete your entire account, and everything in it, whenever you choose.
— PURCHASES—
Cozy Capsule is free to download with up to 3 active capsules. Cozy Capsule Pro is offered as a monthly or annual subscription with a 7-day free trial, and lifts the capsule limit to unlimited for both paired partners. Subscription auto-renews unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID settings.
