Turn your iPhone into part of a decentralized cloud, and receive ACU rewards for it. Acurast lets your phone run small compute jobs for developers. In return, you receive ACU rewards for the work your phone completes. No technical setup needed: if you have a spare iPhone or one sitting on a charger, you can take part. HOW IT WORKS 1. Install Acurast and create your account. 2. Pair your phone as a Processor. It takes about a minute. 3. Start Acurast. Your phone picks up compute jobs and collects rewards as it works. BEST SETUP A spare iPhone on a charger and Wi-Fi is ideal. Start Acurast, let the screen dim, and your phone contributes compute to the network. YOUR PHONE STAYS YOURS - Jobs run in a sandbox, separate from your photos, messages and other apps. - Acurast doesn't collect data linked to your identity. WHAT IS DEPIN? DePIN stands for decentralized physical infrastructure network: real devices owned by everyday people instead of one company's data center. Acurast is a DePIN for compute. Developers use Acurast to run apps and AI models on thousands of phones, without depending on a single cloud provider. Rewards depend on the jobs your phone completes and are not guaranteed. Join the Acurast Cloud Rebellion and make your phone part of the unstoppable cloud.
