  More…

  - Sensor smoothing now uses a 1€ filter instead of SLERP, tuned for both the gyro and legacy sensor paths — steadier while still, more responsive while moving. (#1026) - Manual location entry now uses N/S/E/W hemisphere buttons instead of a sign toggle. (#1023, #1025) - Search now ranks the Sun, Moon and planets above stars when they match. (#1042) - minSdk dropped to 28; Android 9 is now supported on a best-effort basis. (#1041) ### Fixed - Region-only Chinese locale tags (e.g. zh-CN without a script subtag) now resolve to the correct Han script in the catalog's locale fallback chain. (#1040) - Fixed a crash in the search dialog's focus handling. (#1020)
• Sep 12, 2026 2.0.5:Apollo
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/39f3036f7e27080bb9c90a91c4352235fdf9e7da/stardroid-v2/assets/release-icons/2.0.3_apollo_icon.png" width="80" alt="Apollo" /> ### Fixed - Fixed catalog search crashing on Android 10, caused by a missing FTS tokenizer in the stock system SQLite. (#1013, closes #1003) - Fixed illegible N/S/E/W/zenith/nadir labels blending into the horizon glow. (#1018, closes #1014) ### Changed

  More…

  - The legacy (non-gyro) sensor path now smooths the fused orientation with the same quaternion smoother as the rotation-vector path, instead of smoothing the accelerometer and magnetometer separately beforehand — the two no longer drift out of sync with each other during motion. (#1011)
• Sep 9, 2026 2.0.4:Apollo
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/f5bf0da555c4173749f4c01ef4c9c1b930b966db/stardroid-v2/assets/release-icons/2.0.3_apollo_icon.png" width="80" alt="Apollo" /> ### Added - The diagnostics report sent from "Send to developers" now includes the app's own recent log lines, giving full stack traces for caught-and-logged exceptions.
• Sep 8, 2026 2.0.3:Apollo
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/25200c9335e2e59795704ef48362f4626cd73dd6/stardroid-v2/assets/release-icons/2.0.3_apollo_icon.png" width="80" alt="Apollo" /> ### Added - Optional smoothing for the fused rotation-vector sensor path. ### Fixed - Search catalog queries no longer crash the app on exception.
• Sep 5, 2026 2.0.2:Apollo

• Sep 3, 2026 2.0.1:Apollo
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/0be3e6b2dbf5f9d8bef75d8c38c06053c6076838/stardroid-v2/assets/release-icons/2.0.1_apollo_icon.png" width="80" alt="Apollo" /> ### Fixed - Fixed a crash on app start for the Greek locale caused by a malformed RA value format string.

  More…

  - M65/M66 no longer lose their primary catalog label to the shared Leo Triplet alias. - The horizon leveller keeps running until a fling actually stops, instead of stopping early. - The warm welcome and terms screens now lay out correctly in landscape. ### Changed - Catalog text now follows the app's selected language, not just resource strings.
• Sep 1, 2026 2.0.0-beta07:Louise
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/46f385c09c1e5316d664bbe94e582480547c5e18/stardroid-v2/assets/release-icons/2.0.0-beta07_louise_icon.png" width="80" alt="Louise" /> _Pre-release development build of the Sky Map v2 rewrite, not a stable release._ ### Added - Full translation coverage across all 28 core languages. - Per-app language support (`android:localeConfig`), letting users pick Sky Map's language independently of the device's system language on Android 13+.

• Aug 30, 2026 2.0.0-beta06:Louise
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/b2930a7965a59d702f679cb71be70521637be30e/stardroid-v2/assets/release-icons/2.0.0-beta06_louise_icon.png" width="80" alt="Louise" /> _Pre-release development build of the Sky Map v2 rewrite, not a stable release._ ### Changed - Disabled all optional-feature experiment gates by default (notifications, satellites, moon/tonight widgets, camera AR, share-sky) pending further validation.
• Aug 13, 2026 1.18.1:Eclipse
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/e85201dcb231780767c993995460e6e40c471a91/stardroid-v1/assets/splashscreens/1_18_0_eclipse_icon.png" width="80" alt="Eclipse" /> ### Fixed - Sun and Moon position accuracy: the Moon's low-precision D22 series (~0.3°) is replaced with the full Meeus ch. 47 series (ELP2000-82 truncated), and the Sun's truncated Keplerian elements (~0.37° off, no aberration/nutation) are replaced with its Meeus ch. 25 apparent position (~0.01°). Both now run on Terrestrial Time via a shared `TimeUtils.julianCenturiesTerrestrial` and in double precision throughout. Eclipse maximum timing, previously off by up to ~30 minutes, now matches published times to within a minute ([#958](https://github.com/sky-map-team/stardroid/pull/958), [#957](https://github.com/sky-map-team/stardroid/issues/957))
• Aug 9, 2026 1.18.0:Eclipse
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/57501506d80c98d10961e14b84e2bfe20a8bc89e/stardroid-v1/assets/splashscreens/1_18_0_eclipse_icon.png" width="80" alt="Eclipse" /> Together, the two `#954` changes below let you preview how much of the Sun will be obscured from your location during a solar eclipse, including the total eclipse of 12 August 2026. ### Added - A **Show true-to-life sizes** setting (off by default) that renders the Sun, Moon, and planets at their real computed angular size instead of the fixed, exaggerated-for-visibility constants, so eclipses render to scale. Size is recomputed every frame — decoupled from the per-body position-update throttle — so the setting takes effect immediately and the Moon's size tracks its continuously changing distance ([#954](https://github.com/sky-map-team/stardroid/pull/954)) ### Fixed

  More…

  - The Moon's position used only geocentric coordinates, ignoring the observer's location on Earth (diurnal parallax) and causing errors of up to ~1° — roughly two lunar diameters. Added `Universe`/`Moon.getTopocentricRaDec` and switched the renderer to use it ([#954](https://github.com/sky-map-team/stardroid/pull/954)) - Overlapping sky map labels are now detected and offset, keeping crowded regions readable ([#944](https://github.com/sky-map-team/stardroid/pull/944), [#764](https://github.com/sky-map-team/stardroid/issues/764)) - Deep-sky object icons sporadically failed to render: `ImageObjectManager` only sized its texture arrays in the `fullReload` branch of `reload()`, but layers loading data asynchronously take the partial path ([#952](https://github.com/sky-map-team/stardroid/pull/952)) - Vega's Simplified Chinese label identified it as Alpha Aquilae (`天鹰座 α`) rather than Alpha Lyrae (`天琴座 α`) ([#951](https://github.com/sky-map-team/stardroid/pull/951)) ### Changed - Redrew the stars and constellations sidebar icons, which previously reused the platform favorite and share glyphs and were easy to confuse ([#955](https://github.com/sky-map-team/stardroid/pull/955)) - Removed the dead `show_planetary_images` point-primitive fallback path, which had no UI ever wired to it ([#954](https://github.com/sky-map-team/stardroid/pull/954))
• Jul 29, 2026 1.17.1:Neptune
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/fa98282713ee8bdb6efaed86a8e5e36b5874d1d2/stardroid-v1/assets/splashscreens/1_17_1_neptune_icon.png" width="80" alt="Neptune" /> ### Fixed - Broken strings in several localizations ([#950](https://github.com/sky-map-team/stardroid/pull/950))
• Jul 28, 2026 1.17.0:Neptune
  <img src="https://raw.githubusercontent.com/sky-map-team/stardroid/aef221a5f55ca57242a4b4c4fb50f4f8f2f3b038/stardroid-v1/assets/splashscreens/1_17_0_neptune_icon.png" width="80" alt="Neptune" /> ### Fixed - Startup crash when `GPS_PROVIDER` was requested without `ACCESS_FINE_LOCATION` permission ([#948](https://github.com/sky-map-team/stardroid/pull/948)) ### Added - Build flavor label (Gms/F-Droid) on the Diagnostics screen version row ([#949](https://github.com/sky-map-team/stardroid/pull/949)) ### Announcement

• May 5, 2026 1.14.2:Jupiter
  ### Added - **Virtual objects** — Jupiter's Galilean moons (Io, Europa, Ganymede, Callisto) and Mars's moons (Phobos and Deimos) are now searchable with rich info cards and NASA imagery, without appearing as separate points on the star map ([#809](https://github.com/sky-map-team/stardroid/pull/809), [#813](https://github.com/sky-map-team/stardroid/pull/813), [#817](https://github.com/sky-map-team/stardroid/pull/817)) - **Expanded deep sky catalog** — dozens of new objects added including the Double Cluster, 47 Tucanae, the Exposed Cranium Nebula (PMR 1), Brocchi's Cluster and many more, each with

  ([#788](https://github.com/sky-map-team/stardroid/pull/788)) ### Changed - **Gallery redesigned** — replaced the sideways-scrolling list with a grid layout that integrates with info cards for a much improved browsing experience ([#778](https://github.com/sky-map-team/stardroid/pull/778), [#779](https://github.com/sky-map-team/stardroid/pull/779)) - **"Messier objects" renamed to "Deep sky objects"** — the catalog of nebulae, clusters, and galaxies is now labelled more accurately throughout the app ([#772](https://github.com/sky-map-team/stardroid/pull/772)) - **EULA shortened** — the in-app EULA is now a friendly summary with a link to the full text; translated into core languages - **Translations** — Brazilian Portuguese help, EULA, and info cards updated ([#783](https://github.com/sky-map-team/stardroid/pull/783)); Polish HTML formatting fixed ([#781](https://github.com/sky-map-team/stardroid/pull/781)); language-apology strings removed for primary languages that are now nearly fully translated ### Fixed - **Info cards not responding to taps** — fixed a scoping bug that broke tap-to-navigate on info cards - **Night mode not applied to overflow menu** — menu items now correctly use night-mode colours ([#780](https://github.com/sky-map-team/stardroid/pull/780)) ## New Contributors * @utafrali made their first contribution in https://github.com/sky-map-team/stardroid/pull/653 * @izzietaylor123 made their first contribution in https://github.com/sky-map-team/stardroid/pull/750 **Full Changelog**: https://github.com/sky-map-team/stardroid/compare/v.1.11.1...v1.13.3
• Mar 24, 2026 1.12.3:Earth
  ### Added - **Willman 1 (Beth Willman Galaxy)** added to the star catalog — an ultra-faint dwarf satellite galaxy of the Milky Way, notable for its extreme dark-matter dominance and tidal disruption ([#736](https://github.com/sky-map-team/stardroid/pull/736)) - **Info cards for 24 named stars and 41 constellations** — these objects now display educational text cards with discovery notes, mythology, and key facts ([#708](https://github.com/sky-map-team/stardroid/pull/708)) - **App-specific language** — users can now set Sky Map's display language independently of their device's system language via Settings → Language ([#760](https://github.com/sky-map-team/stardroid/pull/760))
