v1.3.0 Nightscout Live Major Latest
February 18, 2026
New Features
  • 📡
    Live CGM via Nightscout Pro — Real-time FreeStyle Libre 2 & 3 readings now flow directly into Mr. Spike. Glucose is auto-filled in the rescue flow, trend arrows update automatically, and low detection triggers lock-screen alerts. Requires Nightscout Pro account (€4.99/mo, billed by Nightscout).CGM
  • 🔔
    Smart low alerts — Customisable lock-screen notifications when your glucose crosses your low threshold, including a one-tap shortcut directly into the rescue flow.
  • 📈
    Auto-outcome tracking — When Nightscout is connected, Mr. Spike reads your post-rescue glucose automatically. No more manual outcome check-ins unless you want them.
Improvements
  • Rescue plan generation is now 40% faster — response time reduced from ~800ms to ~480ms on average.
  • 🎨
    Redesigned home screen glucose card — larger reading display, clearer trend indicator, more breathing room.
  • Improved accessibility — all interactive elements now meet WCAG AA contrast ratios. Dynamic Type supported throughout.
Bug Fixes
  • 🐛
    Fixed a rare crash when opening the rescue flow immediately after app launch on iOS 17.
  • 🐛
    Fixed food library portions not saving correctly when carb value contained a decimal comma (EU locale).
v1.2.0 Weekly Insights Minor
January 14, 2026
New Features
  • 📊
    Weekly Insights report — Every Monday morning, a card summarises your rescues, your most-used foods, your average rebound, and your stability trend vs. the previous week.
  • 🏆
    Stability score — A simple 0–100 score based on how well you stayed within range after each rescue. Gamifies the right behaviour without being preachy.
  • 🌙
    Overnight mode — Reduced notification frequency and softer alert sounds between 11pm–6am (customisable).
Improvements
  • 🧠
    AI personalisation now considers time-of-day patterns — if you consistently need more carbs at night, the plan adapts automatically.
  • 📱
    Timer screen redesigned with a larger countdown, calmer background animation, and clearer "don't add more yet" messaging.
v1.1.0 AI Personalisation Minor
March 28, 2025
New Features
  • 🧠
    AI recommendation engine v1 — After 5+ completed rescue sessions with outcomes, Mr. Spike starts learning your personal glucose response curve and subtly adjusts carb suggestions. Bounded conservatively: never below 10g or above 30g without a clinical reason.
  • 📋
    Rescue history log — A full searchable log of every rescue session with start glucose, treatment taken, outcome, and context.
  • ⚙️
    Custom thresholds — Set your own low (default 70 mg/dL) and very low (default 54 mg/dL) thresholds to match what your care team recommends.
Bug Fixes
  • 🐛
    Fixed activity selector not persisting between sessions.
  • 🐛
    Fixed "Why this amount?" explainer sheet not opening on first tap.
  • 🐛
    mmol/L users: fixed rounding error that showed 3.95 as 4.0 in some edge cases.
v1.0.1 Hotfix Patch
February 24, 2025
Bug Fixes
  • 🐛
    Critical fix: timer not starting on iPhone SE (1st gen) running iOS 16.0.
  • 🐛
    Food library: emoji in food names caused keyboard to dismiss unexpectedly.
  • 🐛
    Onboarding: "Get Started" button was not tappable on iPhone 12 mini in certain orientations.
