Circuit Stream v2.0.0 — Kotlin Android App

Circuit Stream v2.0.0 replaces the Capacitor Android container with Kotlin while preserving the responsive mobile web interface.

• Bundled mobile UI with the new Circuit Stream logo and Android splash screen.
• Kotlin lifecycle handling, back navigation, system insets, loading errors, and external links.
• Fixed header search-button alignment by removing duplicate Android safe-area padding.
• Live telemetry, session results, lap timing, race control, and circuit exploration use the existing backend.

Android package: com.circuitstream.f1
Version: 2.0.0 (build 20001)
Requires Android 6.0 or later and internet access for race data.

Download CircuitStream-v2.0.0.apk below. This APK is debug-signed for direct installation and testing; it cannot update an installed app signed with a different key. Production signing requires the original release key.

Validation: production web build, Android APK build, lint, 2 Kotlin unit tests, 14 frontend tests, and APK signature verification passed. Device testing is being performed by the app owner.

Circuit Stream v1.4.0 - Mobile UI Enhancements & API Stability

This release focuses on dramatically improving the mobile experience across all analytical pages and enforcing backend API stability by removing aggressive background caching that triggered upstream rate limits.

🚀 What's New & Improved

Mobile Responsive Overhaul

• Mobile Filter Stacking: Re-engineered the control headers (Year, Event, and Session dropdown selectors) on all analytical pages to forcefully stack vertically at 100% width on mobile screens (< 768px), providing significantly better touch-targets.
• Fluid Data Tables: Added white-space: nowrap handling to all data tables (Results, Lap Times, Telemetry). Tables now elegantly scroll horizontally on mobile devices rather than word-wrapping and creating unreadable, massively tall rows.
• Premium Headers: Resolved an issue where massive page titles (e.g., "WORLD CHAMPIONSHIP STANDINGS") would crush the Season selector buttons. Titles now dynamically scale down and stack on top of the selectors on mobile viewports.
• Season Stats Centering: Transitioned the Dashboard's "Season Stats" widget from CSS Grid to Flexbox. This guarantees pixel-perfect vertical and horizontal centering of the stat boxes (Total Races, Current Round, Races Left) regardless of the screen's aspect ratio.

Backend API & Stability Fixes

• Removed Aggressive Background Syncing: Completely ripped out the flask-caching and APScheduler background task loop. This resolves the intermittent 502 Bad Gateway and 500 Internal Server Error responses that were occurring when the Heroku dyno woke from sleep and aggressively pinged the Jolpi and FastF1 APIs simultaneously, triggering rate-limits.
• Android Build

Android Capacitor environment updated.

• versionCode bumped to 5.
• Pre-built APK (Circuit-Stream-v1.4.0.apk) generated and attached to this release.

Circuit Stream v1.3.2 - 2026 Grid Update & Android Installation Fix

v1.3.2 - 2026 Grid Update & Android Installation Fix

Just in time for the Australian Grand Prix, this release brings the app up to date with the 2026 season roster, introduces a refreshed brand identity, and resolves critical Android app installation issues and dashboard bugs!

🏁 2026 Season Ready

• New Driver Portraits: Fully updated driver images for the 2026 season. Includes all the latest team changes (Hamilton in Ferrari, etc.) and new rookie headshots across the grid.
• Brand Refresh: Introduced a brand new Circuit Stream logo.
• App Icons: Complete visual update for Android app icons using the new logo for a polished, native look on your home screen.

🐛 Bug Fixes

• Dashboard Upcoming Race Logic: Fixed a bug where the dashboard hero section would accidentally skip the immediate next race (e.g., Australian GP) and show the following one (e.g., Chinese GP) if the race was within exactly 7 days. The countdown and race detection logic is now perfectly strict and sequential.

📱 Android App Improvements

• Signed Release APK: Previously, the Android app was built as a debug package, which caused "App not installed as package appears to be invalid" errors on strict Android forks (like Motorola / Android 14+ devices) or when shared via WhatsApp.
• The app is now compiled and bundled as a fully functioning, ** Digitally Signed Release APK** (v1.3.2) to ensure flawless installation across all Android devices!

📦 Downloads

• Web App: Live now at circuitstream.app
• Android App: Download the newly signed CircuitStream_v1.3.2_Release.apk from the assets below.

(Note for Android users: If transferring the APK via WhatsApp, please send it as a "Document" to prevent the messaging app from compressing or corrupting the package signature).
