Pay Buddy Pro — Release Notes

Note

Newest version first. Screenshots show representative UI for each feature area.

v1.0.0 — 2026-07-21 (UI Refresh)

Design update from the latest Figma pass (file XEF0LHDImMj9R8ImCunKkA, canvas "UI Update"). Documented ahead of code — implementation is pending; see context for status.

What's New

  • [New] Appearance / Dark Mode — Settings → Appearance → Select a Theme: Dark Theme, Light Theme, or System Default
  • [Improved] "Look" tab renamed to "Customise" — same three sub-tabs (Presets, Library, Saved); icon changed to a palette
  • [Improved] "Hot" preset category renamed to "Popular" — categories are now Popular, Cartoon, Animal, Portrait, Art, Landscape
  • [Improved] Editor and Sync merged into one screen — the My Devices list and Sync To Device button now live at the bottom of the image editor; no separate device-picker screen
  • [Improved] Device Detail screen restructured — actions are now Customize, Locate Device, Assign To Profile, Device Guide, Unpair Device
  • [Improved] Pairing flow CTA correction — the naming/profile-assignment step's primary button is Pair Device (profile creation is a secondary + Create A Profile action on the same screen)
  • [Improved] Device limit is explicitly 100 — the Device Limit Reached message now states "You've reached the maximum limit of 100 devices"
  • [Improved] Bluetooth Access Denied dialog — confirmed to include both Open Settings and Close actions

Internal Notes

  • Source: Figma node 1832:15113 ("UI Update" canvas), pulled 2026-07-21.
  • Code status: not yet implemented — pubspec.yaml is 1.0.0+8 with no ThemeMode, dark-mode, or "Customise" strings anywhere in lib/. Per user direction, this is documented against the current v1.0.0 (not a v2.0.0 bump); engineering to reconcile when implementation lands.
  • Screenshot assets not yet updated — no Figma image-export tool was available this session (only inline preview screenshots), and pulling the FIGMA_TOKEN from .claude/settings.local.json to call the Images REST API directly is blocked by the org's secrets-handling policy. The following existing assets are now stale relative to this entry and need a manual re-export: look-presets.png, look-library.png, create-profile.png, edit-image.png, sync-to-device.png, settings.png, home.png, device-limit-reached.png (plus a new settings-theme.png for the Select a Theme sheet).
  • Figma frame 1832:25611 ("Scan Complete - Device not Founđ") turned out to be a duplicate of the Bluetooth Access Denied dialog over the BLE Discovery screen, not a distinct "no devices found" design — no action taken.
