Release notes

What changed in each version of Doodle Dragon Studio.

1.6.0 — Beta hardening

The release prepared for Play testing and TestFlight, focused on finishing complete books reliably on real phones.

New

  • Editable covers with first-page artwork by default, replacement artwork, crop and position controls, title, subtitle, author, optional editable footer, and matching exports. Blank Book starts without a theme footer.
  • Page narration timing keeps a still photo visible for the full recording instead of clipping narration to a fixed page duration.
  • Video trimming with a visual timeline and selectable start and end points.
  • Built-in story music choices alongside imported music, narration, and original video sound.
  • Help & diagnostics in Account shows the exact app version, build, environment, and a copyable support summary.

Changed

  • The page editor keeps the canvas visible while text, media, sound, and layout controls are adjusted.
  • Project canvas ratio and per-page layout are independent. Crop and position controls handle portrait, square, and landscape source media without silently stretching it.
  • AI image and video requests follow the project canvas when choosing a supported generation ratio.
  • AI video currently offers the remotely controlled Economy and Balanced tiers. A tier may be hidden temporarily when provider capacity changes.
  • iOS video export now mixes narration and music, matching Android behavior.
  • The supported iOS minimum is consistently iOS 15.

Safeguards made clearer

  • Studio Plus provides 20 credits per monthly period with a 16-credit daily creation safeguard.
  • Up to six creation requests may start per minute, and only one AI video runs at a time.
  • Provider failures, safety refusals, and empty or corrupt outputs return their reserved credits automatically.

1.5.x — Studio

The release that turned Doodle Dragon from a set of drawing tools into a studio for making books.

New

  • Projects and books replace the old Sketching, Tracing, and Imagen screens. Work is organised around a project you keep, not a tool you open.
  • AI page planning — turn one written idea into editable page text, layouts, and artwork suggestions, with optional matches from your existing Library.
  • The illustration recipe — the description and style sent for every AI image are now shown to you in editable fields before anything is generated.
  • Page editor with per-page layout overrides, drag-to-reorder, and confirmed page deletion that leaves the page media in Library.
  • AI video clips at four, six, or eight seconds, individually priced and confirmed through a remotely controlled capability catalogue.
  • AI narration in a choice of voices, alongside the existing recording and audio import.
  • Story music with a “lower music under narration” control.
  • Project export and import as .ddstory archives, with safe validation.
  • Plan and credits screen showing the remaining balance and the next reset date, with per-action costs shown before you confirm.
  • On-device photo editing — light, contrast, colour, warmth, and the Original, Warm, Storybook, and Clean B&W looks. Free and offline.

Changed

  • Repositioned for parents. AI creation belongs to an account holder aged 18 or over. The books remain for everyone.
  • Credits replace token quotas. Costs are shown in units you can understand, before you spend them.
  • Video is priced per model and duration rather than at one flat rate, so a short Economy clip is not charged like a longer Balanced one.
  • Failed and safety-refused generations now refund automatically.

Removed

  • Tracing mode, its remote image library, and its feedback flow.
  • Developmental sketch analysis.
  • User-supplied API keys in the production UI. Keys are held server-side.

Older releases predate the Studio rework and are not documented here. Have a question about a change? Get in touch.
