A four-mode privacy sweep for hotel rooms, rentals, changing rooms and your own bag. ITEM TRACKER DETECTION • Identifies nearby AirTag, Tile, SmartTag and Chipolo trackers by their Bluetooth signature • Follow detection — the app remembers what it has seen, so it can tell you when the same tracker keeps reappearing across separate sweeps in different places. That pattern, not a single sighting, is what matters • Distance band by signal strength, so you can walk toward it • Your own paired devices are filtered out, and anything found is labelled as a lead to check, never as proof CAMERA AND ROOM SWEEP • Lens reflection check — a guided walkthrough that uses the camera to help you spot the glint of a lens in vents, smoke detectors and mirrors • Bluetooth device scan — counts nearby signals and flags unnamed devices sitting close by • Magnetic anomaly — takes a two-second baseline when the scan starts, then alerts on field spikes as you sweep past fittings ROOM-BY-ROOM SWEEP LIST Work through bedroom, bathroom, living room and office, marking each as swept. Progress saves itself, so an interrupted sweep can be picked up later. RECORDS • Every scan is saved with a 7-day trend and a plain-language summary • Note and favourite any scan; compare two saved scans side by side • Export as CSV or share a single result • Watchlist — mark a device as suspicious and the app tells you when it shows up again WHAT THIS APP CAN AND CANNOT DO iPhone cameras have infrared-cut filters, so this app does not see infrared. The lens check works on reflection: a lens returns a distinctive glint when light hits it straight on. Bluetooth gives you presence and rough distance, never direction. Magnetic detection depends on starting somewhere clean and sweeping slowly. No phone app can guarantee a room is clear — use all four checks together, and treat every hit as something to look at rather than a verdict. If you believe you are being followed or watched, contact local authorities. This app is a tool for looking, not evidence. Available in 25 languages.

「かきみほん」は、紙に文字を手書きするとき、iPhoneを横に置いて見ながら書くための文字見本アプリです。 病院の問診票、役所の申請書、配送伝票、各種申込書など—— 「普段はスマートフォンばかりで、いざ紙に文字を書こうとすると漢字の細部が思い出せない」 「小さく表示された文字だと、細かなハネやつくりが見づらい」 そんな場面で、書きたい文字を入力するだけで、画面いっぱいに大きな見本を表示します。 文字の練習帳や漢字辞書ではなく、書く直前の「手元の見本」として使うことだけに特化しました。 ◆ 主な利用シーン ・病院やクリニックの問診票・同意書の記入 ・市役所・区役所などの各種手続き書類 ・宅配便や郵便の送り状・伝票 ・銀行や各種サービスの申込用紙 ・のし袋や手紙の宛名・芳名帳の手書き時 ◆ かきみほんの特徴 1. 入力して閉じるだけのシンプル操作 文字を入力してキーボードを閉じると、余計な枠や装飾が消え、文字を大きな見本として表示します。 2. 手書き中に画面が消えない 見本を表示している間は画面の自動スリープを防止。書き写している途中で画面が暗くなりません。 3. 縦画面・横画面の両方に対応 iPhoneを横向きにすれば、横長の画面を活かして文字を確認できます。 4. 「縦に見る」に対応 縦画面では、漢字・ひらがな・カタカナを上から下へ並べて表示できます。 5. 書き文字と明朝体から選べる 見本の字体を、書き写しやすい「書き文字」と「明朝体」から選べます。あとから設定で変更することもできます。 6. 広告なし・登録不要・完全オフライン 広告は表示しません。アカウント登録やログインも不要です。入力した文字は保存せず、外部へ送信することもありません。オフラインで利用できます。
