Current Answer: Dark Mode Moved From Roadmap to Real Mobile Beta Builds in 2026
The January 2026 thread said Zima Client dark mode was on the roadmap and would take time because the whole interface needed adaptation. That statement became outdated quickly. By March, the iOS v1.3.0 beta included Dark Mode; by July, Android v1.5.2 beta shipped a redesigned interface with Dark Mode support. So the useful current answer is no longer “planned”—it is “available in the new mobile UI, with rollout depending on platform and release channel.”
iOS Received Dark Mode in the March Beta
The iOS TestFlight announcement listed Dark Mode as part of the redesigned v1.3.0 beta. The community release record is useful historical evidence, while users should still install the newest App Store/TestFlight version available to them rather than hunting for that exact beta.
Apple's iOS dark appearance explains how apps should adapt to system appearance.
Android Added Dark Mode in v1.5.2 Beta
IceWhale's July 2026 Android beta announcement explicitly lists a brand-new UI and Dark Mode. That means the original feature request was materially implemented on Android as well.
Android's Android dark theme provides the platform behavior.
Use System Theme When the App Supports It
The best mobile experience is usually three-state behavior: Light, Dark and Follow System. If the current client exposes only light/dark, choose the one you prefer. If it follows the OS automatically, changing iOS/Android appearance should update the client without a separate app toggle.
Do Not Confuse Mobile Theme With ZimaOS Web Theme
The original request also asked for a custom logo on the ZimaOS web login page. That is a separate customization feature. A dark mobile client does not imply that the web login, dashboard or every embedded app supports custom branding or the same theme.
Why Dark Mode Needed More Than Inverting Colors
Storage charts, thumbnails, warning states, QR codes, dialogs and embedded web content all need contrast checks. A correct dark theme must preserve readable text, accessible focus states and meaningful warning colors. This explains why the roadmap response described gradual rollout rather than a single CSS switch.
Test Dark Mode Where Problems Usually Hide
Check Files previews, photo grids, app cards, login forms, offline/error banners, storage graphs and remote-connection screens. If a white panel or unreadable label appears only in dark mode, capture the screen and exact client version.
The ZimaClient device access gives the broader client workflow.
Custom Branding Remains a Different Requirement
A logo upload affects shared/login identity and possibly multi-user environments, while dark mode is a local display preference. Product planning should treat them separately. The ZimaOS app requirements is relevant when the real need is branding individual apps rather than the NAS shell.
Keep Release-Channel Expectations Clear
Beta/TestFlight features can appear before a stable store release and may still change. When documenting dark mode, name the platform and release channel rather than claiming every installed Zima Client has it.
Use Screenshots to Separate Theme Bugs From Content Bugs
If a card is unreadable only in dark mode, capture the same screen in light and dark appearance. That side-by-side evidence shows whether the defect is contrast, an asset with a fixed white background, or content that fails in both themes. Include system appearance, client version and device model so the issue can be reproduced.
FAQ
Does Zima Client support Dark Mode now?
Dark Mode appeared in 2026 iOS and Android beta releases. Availability depends on the platform and current release channel.
Was Dark Mode only a roadmap item?
It was in January 2026, but later 2026 beta releases implemented it.
Does the ZimaOS web dashboard use the same theme?
Do not assume so. Mobile-client appearance and the ZimaOS web interface are separate products.
Can I add a custom ZimaOS login logo?
The January roadmap reply said custom logos were planned, but Dark Mode implementation does not prove that branding feature is now generally available.
How should I report a Dark Mode bug?
Include platform, app version, screen name and a screenshot showing the contrast or rendering problem.
