Open Drawing in the app

No purchase, entry form or artwork submission is required. Finishing a sketch and rendering it is the goal. Drawing remains available after the challenge.

Do I need to be a developer?

No coding setup or developer account is required. Explore ideas for an app, or simply discover the capabilities of your device.

Will every capability work on my device?

Requires iOS 17 or later. The 214 runnable entries depend on device, OS, permissions and service requirements. Other entries are references for requirements and official documentation. Some experiences need additional hardware or Apple services.

What does it cost?

The first 7 exhibits and the device report are always free. A monthly or yearly auto-renewing subscription unlocks every exhibit. Prices in Japan are ¥100/month or ¥600/year; check your local price in the purchase confirmation.

What can I measure?

The device report times a fixed SHA-256 workload. Selected demos show frame rates or processing times. Temperature and other apps affect results. This is not a remote benchmark service for other devices.

A starting point for your next idea.
