HomemadeCondom (自家製コンドーム) is an iPhone artwork by Akihiro Niimura. A single membrane lives in your iPhone and keeps aging.

How to begin

The app is invitation-only. On the 招待 screen, enter the six-digit invitation code you received. Each code works for a limited period.

You can also begin with a cutting. If someone sends you a cutting, open it with HomemadeCondom on an iPhone that has no membrane yet. The cutting takes root and becomes your membrane.

What you can do

• Touch and drag the membrane. Fingerprints fade after six hours.
• Tilt or shake your iPhone to move it.
• Allow the microphone, and your breath makes the membrane swell and your voice makes it tremble. You can turn the microphone off in Settings at any time.
• Touch and hold the app icon on the Home Screen and choose 挿し木を渡す to pass a copy of your membrane to someone.

Questions

Can I reset the membrane? No. There is no reset. Deleting the app deletes the membrane.

Why does it look different when I come back? The membrane keeps aging while the app is closed. It slowly shrinks, stiffens, yellows, and turns powdery.

Can I receive a cutting if I already have a membrane? No. A cutting takes root only on an iPhone that has no membrane yet.

Does the app use the internet? No. It works offline and sends nothing. See the privacy policy: HomemadeCondom Privacy Policy / 自家製コンドーム プライバシーポリシー
