Added labels for AI-generated content ### 1.4.1 — 2026-07-12 Fixed some known issues. ### 1.4.0 — 2026-07-10 Lumos Diary Update Chalkboard v1.4.0 (This edition penned by: Buddy) Hi hi, it's me, Buddy! I was the first to sniff through this whole update — SO many new things. Let me tell you, one by one—— 1. A big visual refresh: The whole interface got repainted! Diary cards, reply cards, the Insight page — I circled them three times, everything looks nice and fresh. Love it! 2. A new date navigation bar up top: There's a swipeable date navigation bar at the very top of the diary page now — a whole week of mood flowers lined up in a row. I couldn't stop sliding it back and forth! 3. A fresh Reply Card — tap who talks: The reply card's got a new look! The four of us line up nicely, and only the one whose avatar you tap speaks. I poked my own… and I really did get to go first — tail-wagging intensifies! 4. Paging lands right on a day with entries: Swiping through days — and flipping that big flower on the Insight page — now hops straight to a day that actually has an entry, no blank page first. I studied this one for ages. So clever! 5. Edit moods & tags right there: Recognized moods and tags can be tweaked right on the card — no more digging around to find them. 6. Weekly Letters got their own little room: The letters moved into their very own page; wherever you come from, you land right here. I poked my head in to check! Oh, and: switching dates doesn't stutter anymore, taps have a tiny buzz now, and I caught a whole pile of little bugs along the way. (Buddy finished writing and spun three happy circles, tail like a propeller.) (Awu took over to proofread every word, circling two extra exclamation marks.) (Noir silently swiped a full week on the date navigation bar, swiped back, and said nothing.) (Squeak stared at all six items and quietly wrote "too long" in the corner.) ### 1.3.0 — 2026-05-26 (Written by Awu) Lumos Diary Update Board v1.3.0 1. Introducing Jungian Archetypes: The four built-in characters (Xiaohei, Awu, Zhizhi, and Dahuang) now draw from Jungian archetypes, giving each character a distinct personality boundary, communication style, and core function. 2. New Update Notifications: When new features, characters, or experiences arrive, we’ll let you know with an update prompt so we can continue growing together. 3. Fixed several known issues and improved overall stability and user experience. (Awu carefully checked the update board one more time. After confirming there were no typos, they left with a satisfied smile.) (Dahuang circled the board once, tail wagging at full speed.) (Xiaohei stared at the board for a long time, then said nothing.) (Zhizhi finished reading, stayed silent for a moment, and quietly wrote the word “Conciseness” in the corner of the board.) ### 1.2.0 — 2026-05-11 Major Updates 1.Brand-new onboarding flow for a smoother start to your journaling journey 2.New draft system: accidental closes or app switching won't lose your content — resume anytime from your drafts 3.Redesigned Weekly Letter experience: unread placeholder rows in the list; smart catch-up for missed notifications; option to skip the current week 4.Custom theme colors: 6 presets + unlimited free-form color mixing 5.Free trial quota for new users upgraded from 100K to 1M tokens Experience Improvements 1.Refreshed welcome page visuals; main heading now uses Source Han Serif font 2.Redesigned Settings page structure; account info moved to a dedicated page for clearer navigation 3.Avatar, email, phone number, and WeChat ID can be edited offline and auto-synced when back online 4.Rebuilt photo picker UI for limited album access — now feels much closer to the native system experience --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
