Android App ​

Mold for Android is the remote-only Mold Studio client. It connects to Mold servers over LAN, Tailscale, or HTTPS and shares the same Create, Library, Models, Machines, and Settings surface as the iPhone app. Model execution stays on the remote machine; per-host API keys are encrypted by an app-owned, non-exportable Android Keystore key.

Android development builds and the current nightly APK are documented in the mobile maintainer guide. Google Play publishing remains release work.

Connect a machine ​

Open Machines and scan the one-use pairing code shown by Mold Studio on the server, discover _mold._tcp machines on the local network, or enter a LAN, DNS, HTTPS, or Tailscale MagicDNS address manually. Pairing transfers a two-minute one-use ticket, not the durable API key.

Identity photos (PuLID) ​

An identity photo conditions a print on a person's face while the prompt owns the scene, styling, and composition. The Identity well appears in the main Create form beside the source wells only when the selected model and target machine positively advertise identity support. It stays hidden for Sequence.

Tap the well and choose one native action:

  • Choose photo opens Android's Photo Picker. Mold requests no broad photo or storage permission.
  • Take photo opens the installed camera through a temporary content URI.

Use a PNG or JPEG no larger than 16 MiB, 8192 px per side, or 32 MP. Android checks the provider-reported file size before reading the photo, and the bytes are sent verbatim rather than cropped or fitted to the canvas. The source sheet uses 48dp controls and the Android back gesture dismisses it without changing the draft.

Switching to a model without identity support parks the attached photo: the well disappears, the identity fields stay off the request, and Develop remains available. Returning to a qualified model restores the well and photo. Identity strength and Identity start step live in Advanced, count toward its badge, and clear with Advanced Reset while the photo remains attached.

Identity requests cannot combine with a LoRA or img2img source. Every refusal is shown inline and queues nothing. Under Auto or Most capable, Mold considers only machines whose own model row advertises identity support and does not use the legacy placement fallback. Prepared Batch siblings inherit the same photo and controls.

Library Info shows the photo name, short SHA-256, effective strength, and start step. Use as prompt restores the controls and re-attaches the exact photo from the device stash; if the bytes are gone, Create reports that miss inline instead of silently using another face. Saved metadata never contains the photo bytes.

See Identity Photos (PuLID) for model requirements, limits, and the one-time InsightFace license acceptance.
