The iPhone setup steps below (3–5) are the part people skip and then wonder why nothing runs. Don’t skip them. An iPhone can’t warm or post until the runner is installed on it.
Sign up and grab your license key
Go to app.warmr.so/signup and sign in with Google. Your license key is delivered instantly to your email and dashboard. No credit card required. The free trial gives you full access to get started.
Install and activate the Mac app
Download the Warmr Mac app from your dashboard, drag it into Applications, and open it. Paste your license key on the activation screen and click Activate. Full walkthrough, including the macOS security prompt: Installation.
Connect your first iPhone
Plug the iPhone into your Mac with a data USB cable, unlock it, and tap Trust when asked. It appears in Warmr’s Devices panel within a few seconds. Details: Connect iPhones.
Prepare the iPhone's settings
On the iPhone, turn on Developer Mode and enable UI Automation (Settings → Developer; without it nothing runs), set Appearance to Light, turn StandBy Off, and set Auto-Lock to Never. These prevent the most common stalls. Full checklist: Prepare each iPhone.
Install the Warmr runner
Install the runner once per iPhone so your Mac can drive it. With a paid Apple Developer account, use the one-button App Store Connect API method. With a free Apple ID, sign in Xcode (Product → Test /
⌘U, not Run). Step by step: Install the runner.Add a social account
Log into the account in its app on the iPhone (for example, TikTok), then add it in Warmr under the connected device. See Adding accounts.
Watching the iPhone scroll its feed on its own means everything is wired up correctly. From here, set a posting schedule and use Cloud Drop to feed in content.
Fresh accounts go through a warmup phase before they join your posting rotation, usually a few days, depending on the platform. Warmr blocks posting until an account has matured. See Account lifecycle.
