This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged.

Streak Stones 2.0 — a pro upgrade that deepens the stone you grow, while keeping everyday tracking calm and minimal. • Lapidary Studio: a live close-up of your stone with a full certificate (grade, clarity, carats, rarity) and cut/finish re-styling that persists, plus "The Journey" to your next tier. • New generative flourishes at long streaks: cat's-eye chatoyancy and dispersion "fire," with rarer inclusions, cuts, and finishes. • Trophy Case: a collectible gallery of every milestone, each earned achievement shareable as a medal card. • Collection collage: one beautiful poster of all your stones to share. • Year-in-pixels heatmap with quiet insights (completion rate, active days, best run). • A gentle grace token so one missed day doesn't reset you, plus per-habit reminders and a palette-derived share-card theme. 100% local — no accounts, no cloud, no analytics. Everything stays on your device.

Version 1.1 (Build 3) • Stone milestones — each habit's detail screen now shows a timeline of when you first earned each tier: the exact date you reached Pebble, Polished Stone, Banded Agate, Faceted Geode, and Radiant Crystal. Your progress, made permanent. • Insights tab — a new fourth tab shows your cross-habit picture at a glance: streaks currently at risk (habits you missed yesterday that still need today's check-in), all-time personal bests, perfect days in the last 30, and a full milestone history across every habit. • Streak-at-risk alerts — a subtle "streak at risk" badge now appears on Today rows when yesterday was a scheduled miss and today is your last chance to save the streak before it resets.

Version 1.1 • Day notes — long-press any day on the heatmap calendar to attach a short annotation (e.g. "ran 5km", "skipped — travel day"). A small dot marks days that have notes. • Weekly stats — a new card on each habit's detail screen shows this week's progress bar, your all-time best week, perfect-week count, and average days per week. • CSV export — alongside the JSON backup, you can now export all your habit data as a CSV spreadsheet ready to open in Numbers, Excel, or any data tool. Find it in Settings → Backup & Export. • Archived habits manager — archived habits are now viewable and restorable from Settings → Habits. History is always preserved.
