NexaSense v1.1.0

NexaSense v1.1.0

Professional compass and level for AOSP and custom ROMs — offline-first, privacy-first, and independent of any vendor framework.

Highlights

• ✨ Google 2026 design language — every icon is now a Material Symbol (Google's official 2026 icon set) instead of the deprecated Material Icons, and the whole app shares one set of Google-settings-style components: compact rows with a colored tonal icon container, a current-value label and a chevron that open a Google-style radio dialog on tap. Options, menus and properties look and behave identically on every screen.
• 🎨 Material 3 Expressive redesign — upgraded to the stable M3 Expressive release (Compose BOM 2026.06.01): a fully rounded expressive shape scale, Google Sans (the official open-source Google typeface, bundled under SIL OFL) with tabular numerals for readouts, unified M3 motion tokens that animate settings accordions, chevrons, list reordering, dialog entrances and tab crossfades, tonal frameless DataCards and EmptyState screens with icons, a settings search bar that filters every option live (Google Settings style), an About screen with runtime version and font/license attribution, and a Google-style bottom navigation where the active tab shows a filled icon that crossfades from the outlined one. Navigation is adaptive via window size classes: phones get the bottom bar, wider windows get a Navigation Rail, and directional icons mirror correctly in RTL.
• 🧭 Compass with a 360° dial, smooth wrap-around heading, adaptive magnetic-interference detection and in-app magnetometer calibration (hard/soft iron). Fixed a 90° compass-rose error: the dial ticks, cardinal labels and the Qibla Kaaba marker are now drawn on the true physical compass rose (0° = top, clockwise), so the marker agrees with the turn hints — a Qibla on your right renders on the right, and turning toward it brings it to the top instead of away. The rose is layout-direction independent, rendering identically in LTR and RTL (a compass must not mirror); pinned by 8 new CompassRoseTest unit tests. Both degree readouts — the heading above the dial and the Qibla card's bearing — now render at headlineLarge (32 sp) in fixed-width slots, uniform with the level screen's readouts: smaller, so no number overshadows the dial, and pinned, so the digits never shift when the value changes (location update, north-reference switch). Three professional dial styles (Classic / Azimuth / Minimal) switchable from Settings, with granular per-element toggles (cardinal labels, degree ticks, degree numbers, heading readout, north-reference badge, source/declination details, accuracy panel) and an auto-hide option that hides the numbers whenever the magnetic accuracy is low. All readouts and bottom details sit in closed cards with fixed-width numeric slots, so the digits changing as you move the phone never shift the text.
• 🌙 Automatic night mode — follows the device (System theme by default) with a deep-navy sky gradient background and a blue-tinted dark palette; light mode gets a soft daylight gradient. The app stays always portrait.
• 🕋 Qibla Direction — fully local WGS84 geodesic bearing to the Kaaba (Vincenty inverse formula on the WGS84 ellipsoid, spherical fallback), 🕋 marker on the dial (always upright), turn guidance with a ±2° alignment threshold, optional distance and haptics, plus a sun-over-Kaaba shadow check: when the sun transits the Kaaba (twice a year) the solar azimuth equals the Qibla bearing, so shadows verify the direction compass-free. Disabled by default; location is requested only while enabled and never leaves the device.
• 🔁 Qibla recovers on its own — the location engine no longer reports "Qibla unavailable" while a fix is still on its way (the status stays "calculating" during the request), and a failed fix is retried automatically every 15 s until one arrives or the screen is closed. The feature comes back by itself indoors, after a cold start, or when location services are switched on — no manual refresh needed. Covered by new QiblaEngineImplTest unit tests.
• 🧭 North Reference — Automatic / True North / Magnetic North with effective-reference resolution always shown (e.g. Automatic · True North).
• 📏 Level — automatically switches by how the device is held: flat shows a two-axis bubble (four directions); held upright shows a water/mercury tube level (left-right) with a plumb gauge whose needle shows the deviation-from-vertical on a degree scale. Every moving element (mercury bubble, plumb needle, flat bubble) glides smoothly instead of snapping, and reaching perfect level lights a pulsing centered dot in both modes. The gauge conventions are pinned in the domain layer (pure functions with the correct convention documented — 0° = straight down, positive = right, top-up hemisphere = negative deviation; the geometry renders identically in LTR and RTL, since a level must not mirror) and covered by 7 new regression tests. Feedback on center: a graded haptic that ramps up in strength as you approach level/plumb in both modes (proximity bands 8°→0.5°), plus a soft confirmation chime with its own settings toggle, independent of the haptics toggle. Zero-point calibration.

Features

• Compass sources by priority: Rotation Vector → Geomagnetic Rotation Vector → Accelerometer + Magnetometer → unavailable (never faked).
• Magnetic declination from the current official WMM2025 model (pure-Kotlin, NOAA-verified to < 0.005°), cached by location/time — never per sensor event.
• Adaptive interference thresholds, no single worldwide constant.
• Three-screen bottom navigation (Compass / Level / Settings) — one instance per tab, state preserved.
• Settings redesigned on the Google Settings pattern: single-choice options (Theme, Language, North Reference, Smoothing, Sensor rate, Compass style) are compact rows showing the current value and open a radio dialog on tap instead of long inline lists; every group and row carries a Material Symbol in a tonal rounded container, switch rows toggle on whole-row tap, and rows are separated by subtle dividers. Qibla keeps its master-switch group with sub-options hidden until enabled. Also: 24 languages (system per-app language picker on Android 13+), Qibla options, compass appearance toggles, haptics, level confirmation sound, keep-screen-on, reset.
• Startup is hardened against broken/partial sensor HALs (common on custom ROMs) — discovery and the per-app locale call degrade gracefully instead of crashing, and a stuck/blocked sensor (Sensors Off toggle, per-app sensor permission) is detected and explained.
• Sensors registered only while a screen is visible — no background collection; non-wake-up sensors preferred.
• Heading stays in the user's frame across display rotations (compensation), and the dial/level cap at 480 dp on large screens.
• 202 unit tests (math, geodesy, geomagnetic WMM2025 model, solar position, engines, calibration, robustness, gauge/bubble conventions), lint-clean; instrumented UI tests run on a device — including CompassDialQiblaMarkerTest, which asserts the Kaaba marker's pixel position matches the turn hint's sign in both LTR and RTL.

Compatibility

• Android 12 – 16 (API 31 – 36), compile/target SDK 36, min SDK 31.
• AOSP ROMs: LineageOS, crDroid, Evolution X, Pixel Experience, GrapheneOS and stock MIUI/HyperOS devices.
• Qualcomm Snapdragon and MediaTek, including Xiaomi / POCO / Redmi phones on AOSP-based ROMs.
• No Google Play Services required — fully offline.
• Missing sensors degrade gracefully (e.g. POCO F5 shows Barometer: Not available) — never a crash, never a fake value.

Localization

English, العربية, Deutsch, Français, Español, Português, Italiano, Türkçe, Русский, Українська, Polski, Nederlands, Bahasa Indonesia, Bahasa Melayu, हिन्दी, বাংলা, اردو, فارسی, 简体中文, 繁體中文, 日本語, 한국어, Tiếng Việt, ไทย — 24 languages with proper RTL support, per-app language selection (System Default follows the device language) and the app name localized per language (e.g. البوصلة, Kompass, Brújula, 指南针).

UI

Material 3 design system (centralized color/shape/typography/dimensions), dynamic color on Android 12+, light/dark/system themes with the night-sky and daylight gradients, Material Symbols icon set throughout, a new Google-2026-style launcher icon (diagonal blue gradient, white compass mark, monochrome themed-icon variant for Android 13+), edge-to-edge on Android 15/16, predictive-back support, TalkBack-friendly content descriptions with a heading live region, and 48 dp touch targets. Per-screen orientation: the compass stays portrait always, while the level and settings rotate freely with the device.

Privacy

Offline-first. No internet, analytics, tracking, ads or telemetry. The only runtime permission is coarse location, requested only for True North/Qibla, and it is never sent anywhere.

Known limitations

• Release APKs are signed with the debug key until a production keystore is configured via GitHub Secrets (NEXASENSE_KEYSTORE_*; see docs/development.md); install by enabling Install unknown apps on the device.
• The release APK is minified with R8 (~3 MB) and bundles a startup baseline profile for faster cold start on Android 13+.
• True North / Qibla require a location fix; without one they show a clear "Location required" state and retry automatically every 15 s until one arrives.
• Instrumented UI tests require a connected device/emulator (./gradlew :presentation:connectedDebugAndroidTest for the compass/level module, ./gradlew connectedDebugAndroidTest for the app).

Material 3 design system (centralized color/shape/typography/dimensions), dynamic color on Android 12+, light/dark/system themes with the night-sky and daylight gradients, Material Symbols icon set throughout, a new Google-2026-style launcher icon (diagonal blue gradient, white compass mark, monochrome themed-icon variant for Android 13+), edge-to-edge on Android 15/16, predictive-back support, TalkBack-friendly content descriptions with a heading live region, and 48 dp touch targets. Per-screen orientation: the compass stays portrait always, while the level and settings rotate freely with the device.

Privacy

Offline-first. No internet, analytics, tracking, ads or telemetry. The only runtime permission is coarse location, requested only for True North/Qibla, and it is never sent anywhere.

Known limitations

• Release APKs are signed with the debug key until a production keystore is configured via GitHub Secrets (NEXASENSE_KEYSTORE_*; see docs/development.md); install by enabling Install unknown apps on the device.
• The release APK is minified with R8 (~3 MB) and bundles a startup baseline profile for faster cold start on Android 13+.
• True North / Qibla require a location fix; without one they show a clear "Location required" state and retry automatically every 15 s until one arrives.
• Instrumented UI tests require a connected device/emulator (./gradlew connectedDebugAndroidTest).

Installation

Download NexaSense-v1.0.7-release.apk below, enable Install unknown apps for your browser/file manager, and open the file. No permissions are requested at install time; location is requested only when you enable True North or Qibla.

NexaSense v1.0.6

NexaSense v1.0.6

Professional compass and level for AOSP and custom ROMs — offline-first, privacy-first, and independent of any vendor framework.

Highlights

• ✨ Google 2026 design language — every icon is now a Material Symbol (Google's official 2026 icon set) instead of the deprecated Material Icons, and the whole app shares one set of Google-settings-style components: compact rows with a colored tonal icon container, a current-value label and a chevron that open a Google-style radio dialog on tap. Options, menus and properties look and behave identically on every screen.
• 🧭 Compass with a 360° dial, smooth wrap-around heading, adaptive magnetic-interference detection and in-app magnetometer calibration (hard/soft iron). Three professional dial styles (Classic / Azimuth / Minimal) switchable from Settings, with granular per-element toggles (cardinal labels, degree ticks, degree numbers, heading readout, north-reference badge, source/declination details, accuracy panel) and an auto-hide option that hides the numbers whenever the magnetic accuracy is low. All readouts and bottom details sit in closed cards with fixed-width numeric slots, so the digits changing as you move the phone never shift the text.
• 🌙 Automatic night mode — follows the device (System theme by default) with a deep-navy sky gradient background and a blue-tinted dark palette; light mode gets a soft daylight gradient. The app stays always portrait.
• 🕋 Qibla Direction — fully local WGS84 geodesic bearing to the Kaaba (Vincenty inverse formula on the WGS84 ellipsoid, spherical fallback), 🕋 marker on the dial (always upright), turn guidance with a ±2° alignment threshold, optional distance and haptics, plus a sun-over-Kaaba shadow check: when the sun transits the Kaaba (twice a year) the solar azimuth equals the Qibla bearing, so shadows verify the direction compass-free. Disabled by default; location is requested only while enabled and never leaves the device.
• 🧭 North Reference — Automatic / True North / Magnetic North with effective-reference resolution always shown (e.g. Automatic · True North).
• 📏 Level — automatically switches by how the device is held: flat shows a two-axis bubble (four directions); held upright shows a water/mercury tube level (left-right) with a plumb gauge whose needle shows the deviation-from-vertical on a degree scale. Every moving element (mercury bubble, plumb needle, flat bubble) glides smoothly instead of snapping, and reaching perfect level lights a pulsing centered dot in both modes. Feedback on center: a graded haptic that ramps up in strength as you approach level/plumb in both modes (proximity bands 8°→0.5°), plus a soft confirmation chime with its own settings toggle, independent of the haptics toggle. Zero-point calibration.

Features

• Compass sources by priority: Rotation Vector → Geomagnetic Rotation Vector → Accelerometer + Magnetometer → unavailable (never faked).
• Magnetic declination from the current official WMM2025 model (pure-Kotlin, NOAA-verified to < 0.005°), cached by location/time — never per sensor event.
• Adaptive interference thresholds, no single worldwide constant.
• Three-screen bottom navigation (Compass / Level / Settings) — one instance per tab, state preserved.
• Settings redesigned on the Google Settings pattern: single-choice options (Theme, Language, North Reference, Smoothing, Sensor rate, Compass style) are compact rows showing the current value and open a radio dialog on tap instead of long inline lists; every group and row carries a Material Symbol in a tonal rounded container, switch rows toggle on whole-row tap, and rows are separated by subtle dividers. Qibla keeps its master-switch group with sub-options hidden until enabled. Also: 24 languages (system per-app language picker on Android 13+), Qibla options, compass appearance toggles, haptics, level confirmation sound, keep-screen-on, reset.
• Startup is hardened against broken/partial sensor HALs (common on custom ROMs) — discovery and the per-app locale call degrade gracefully instead of crashing, and a stuck/blocked sensor (Sensors Off toggle, per-app sensor permission) is detected and explained.
• Sensors registered only while a screen is visible — no background collection; non-wake-up sensors preferred.
• Heading stays in the user's frame across display rotations (compensation), and the dial/level cap at 480 dp on large screens.
• 182 unit tests (math, geodesy, geomagnetic WMM2025 model, solar position, engines, calibration, robustness), lint-clean; instrumented UI tests run on a device.

Compatibility

• Android 12 – 16 (API 31 – 36), compile/target SDK 36, min SDK 31.
• AOSP ROMs: LineageOS, crDroid, Evolution X, Pixel Experience, GrapheneOS and stock MIUI/HyperOS devices.
• Qualcomm Snapdragon and MediaTek, including Xiaomi / POCO / Redmi phones on AOSP-based ROMs.
• No Google Play Services required — fully offline.
• Missing sensors degrade gracefully (e.g. POCO F5 shows Barometer: Not available) — never a crash, never a fake value.
