### 1/5 — データ消えた

*2025-10-08*

アップデートは嬉しいが、過去の撮影データが全て消えた。
本当に復活させて欲しい。当時課金をして日本全国5年分くらい撮り溜めてた雲記録が全て消えた。アプリの作成者様どうにかならないですか？
お返事待ってます。

**Developer response:** ご報告ありがとうございます。そして、5年分にわたって日本全国で撮りためてくださった大切な雲の記録を、アップデートを機にアプリ内から見えなくしてしまったこと、本当に申し訳ありません。心からお詫び申し上げます。

先日公開した 2.2.0 に、端末内に残っている旧データを自動的に取り込み直す復旧処理を組み込みました。お手数ですが、

1. CloudWatcher を 2.2.0 以降に上書き更新 (削除→再インストールは絶対に避けてください。iOS の仕様で旧データごと消えてしまいます)
2. 更新後、初回起動時に自動で復旧が走ります

これで5年分の記録が戻れば何よりです。

もし戻らない場合、もしくは過去にアプリを一度削除されたことや機種変更で当時の端末を手放されたことがある場合は、技術的に復旧不可となっている可能性があります。

長年使ってくださっていた方ほど影響が大きく出る、最も避けるべき種類の不手際でした。深く反省しています。引き続きどうぞよろしくお願いいたします。

## Version history (last 5 releases)

### 2.3.0 — 2026-06-07

This update adds a welcome experience for new users and makes learning more rewarding.

New and improved
・Added an onboarding flow for first-time users.
・Learning is more fun: cloud collection progress, cumulative quiz stats, and achievements.
・Open AR mode (point at the sky to label clouds) in one tap from the Learning screen.
・Tapping a sky-moment notification now opens the camera right away.
・Privacy: location is now off by default when sharing (you can still choose each time).

Fixes
・Fixed the share screen location toggle occasionally switching back off.
・Fixed "Unknown" briefly appearing while a new photo is being analyzed.
・Daily quiz streaks now count correctly.
・Startup optimizations and stability improvements.

### 2.2.1 — 2026-05-12

What's New

• Polished English experience. We've fully localized the app's English UI — home, quiz, share, weather, and error screens now read naturally. Camera, location, and photo-library permission prompts are also localized.
• Easy reviews. Tap "Rate App" in Settings to open the App Store review page directly. We may also ask for a quick rating from inside the app after positive moments.
• Bug fixes: removed a duplicate Close button on the Statistics screen and fixed a missing space in the "186 clouds recorded" counter.

### 2.2.0 — 2026-05-07

A Sincere Apology

In October 2025, we shipped version 2.1.0 as a complete rewrite of the app's internals. During that overhaul, we failed to migrate the cloud observation records that you had saved in the previous (Objective-C) versions of CloudWatcher.

For everyone who carefully recorded the skies day after day, and for those who had only just begun — we are deeply sorry that your records appeared to vanish from the app, and that it has taken us this long to address it. Please accept our sincerest apologies.

Recovering Your Old Data (Important)

This update includes a one-time recovery routine that automatically imports observation data left on your device by the previous version of the app.
・It runs automatically on the first launch after updating
・If the legacy data is still in the app's sandbox, your cloud names, timestamps, locations, memos, and photos will be restored to the new list
・Recovered photos are stored as legacy_*.jpg files

Unfortunately, in the following cases the data cannot be recovered:
・If you ever deleted the app and reinstalled it in the past (iOS clears all app-internal data the moment an app is removed)
・If you have switched to a new device and no longer have the device that contained the older app

We're truly sorry for this limitation.

Version 2.2.0 Another updates — A new way to look up at the sky
AR Labeling — A new third capture mode. Point your camera at the sky and tap any cloud to identify it on the spot. Labels stick in 3D space, so you can compare multiple cloud types in a single view.

Live Activity: Today's Sky — Your Lock Screen and Dynamic Island now show what's likely in the sky today — rainbows, sunsets, sunrises, halos, cirrus days, and clear nights — in chronological order. Never miss the right moment to look up.

Smart Sky Alerts — CloudWatcher reads the forecast and sun position to predict moments like "Rainbow likely" or "Beautiful sunset expected" and notifies you just before. Alerts mirror to your Apple Watch automatically. Toggle each type independently.

Refreshed Camera UI — Mode switching now lives in the navigation bar, giving every mode a full-screen camera view.

### 2.1.4 — 2025-11-16

* Fixed bug in landscape mode camera.

### 2.1.3 — 2025-10-13

- Add Cloud Map
- Design refinement
