· Pro radars – values for velocity, correlation coefficient, differential reflectivity, and other products
First-tap responsiveness fixed – no more delays or missing pins on initial use.

TAP ON MAP
Stop guessing precipitation intensity from colours. Tap anywhere on the radar to see exact dBZ values. Know precisely how strong that storm cell is, whether it's light drizzle or a severe hail threat. Satellite layer reveals cloud top temperature – colder tops mean taller, more powerful storms. Temperature layer shows surface readings from weather models. Hybrid layer adapts to show relevant data based on tap location. Tap alert zones to see full details. Toggle in Settings.
Stay tuned!

7.7.3 24/11/2025
TIMELINE PLAYER ENHANCEMENTS
The radar timeline player interface has been completely redesigned with precision controls for weather tracking.
• LIVE mode indicator now activates when you're viewing the most recent radar frame, updating automatically as new data arrives. When radar updates lag beyond 15 minutes, it displays the relative time since the last update. After 30 minutes without updates, it switches to LATEST with a timestamp to indicate the data's gone stale.
• Timeline markers visually indicate each available radar frame directly on the slider with up to 40 position markers, making it clear which moments have actual data. Markers are off by default – enable them in Map Settings for enhanced timeline visualisation.
• Synchronised timeline ranges across layers – forecast ranges now persist when switching between radar, satellite, and composite layers. Separate synchronisation groups maintain appropriate timescales: 72-hour precipitation and temperature layers sync together, whilst real-time radar and satellite layers maintain their own ranges.
• Resolved timeline switching bugs where manually selected frame positions would reset incorrectly when changing between radars with different update intervals. The player now correctly maintains position context across radar transitions.
• Fixed haptic feedback rate limiting at 32Hz – the hardware maximum – eliminating feedback interruptions during rapid scrubbing.
INTERACTIVE WEATHER CHALLENGE
Discover five legendary weather events hidden across the map. Tap map markers to explore historic storms and unlock exclusive rewards. Coming soon to select users – keep an eye out for this unique experience.
NOTIFICATION PERMISSION FLOW
Fixed a premature system notification dialogue appearing before users completed the onboarding preferences screen. Permission requests now trigger only after you've explicitly engaged with notification settings during onboarding.
REGRESSION TESTING & STABILITY
Comprehensive testing across core features validates update stability. Interface consistency, data integrity checks, and performance validation completed across iPhone, iPad, and macOS platforms.

7.7 12/11/2025
CRITICAL FIXES
• Fixed a startup crash that occurred when reopening the app after last viewing the Favourites screen. We've eliminated the race condition in map initialisation by properly sequencing dependencies.
• Sorted out the Apple Watch subscription restore feature following our billing system migration. Purchase verification through StoreKit now works properly with extended 120-second timeouts for more reliable network responses.
• Storm tracking lines now stay put after backgrounding. We've enforced map layer state restoration through lifecycle management, ensuring your premium features remain visible when switching between apps.
IMPROVEMENTS
• Optimised onboarding screens for iPhone SE users. Layout adjustments prevent images from getting clipped and text from being squashed on compact displays, whilst keeping everything looking great on larger devices.
7.5.2 03/11/2025
STABILITY & RELIABILITY IMPROVEMENTS
Fixed a critical crash in the forecast view when looking at single‑day weather data. Eliminated a division‑by‑zero issue by adding stricter input validation and geometry checks, covering right‑to‑left (RTL) layouts and other edge cases.
Refined connection handling for the weather map and added a manual reload option. Error messages are clearer, automatic retries now kick in, and there’s a Force Reload button for stubborn connectivity problems.
Improved premium subscription detection to stop ads appearing during background verification. Ads now disappear straight away as soon as your subscription is confirmed.
7.5.1 21/10/2025
LIVE ACTIVITIES MAJOR UPGRADE
We’ve completely rebuilt Live Activities from the ground up, replacing the unreliable architecture that led to duplicates, stale data and activities getting stuck on the Lock Screen.
· Automatic initialisation when you open the app – no need to open individual favourites
· Backend push updates synchronised with the rain forecast refresh cycle (every 10 minutes)
· Activities auto-dismiss when precipitation ends, typically within 10 minutes
· 'Outdated' indicator appears if updates fail for 15 minutes – so you know when data is stale rather than guessing
· One-hour timeout clears stuck activities as a final safeguard
· Timer counts down to both the start and the end of precipitation
· Race condition handling eliminates duplicate activities
Push-driven updates from our backend enable reliable server-side management and proper lifecycle clean-up.
LIVE ACTIVITIES SETTINGS
Granular control over when and how Live Activities appear. Toggle globally or per location. Set a precipitation intensity threshold – from any precipitation to only heavy rain or hail. Activities stay active for up to 8 hours with continuous radar updates.
REFRESHED APP ICON
Updated to a refined blue icon across the iOS Home Screen and system interfaces.
Stay tuned.
