Why is the model taking long to download?
The Google Gemma 4 model is approximately 3.6 GB. Depending on your Wi-Fi or cellular speed, the initial setup download can take a few minutes. Please make sure the app remains active in the foreground during the first download to prevent iOS from suspending the download task.
Which devices are supported?
Sunday runs the neural network natively on your iPhone's Apple Silicon GPU. For optimal speed, we recommend iPhone 15 Pro, iPhone 16, or newer. Older devices with less than 6GB of Unified Memory (RAM) may experience slower load times or memory limitations.
How do I delete my data?
Because Sunday is 100% private and offline, all data is stored strictly in your local app sandbox. You can clear your entire history by tapping "Clear History" inside the settings tab in the app, or by uninstalling the application from your iOS device.
