親戚が増えるほど、線が重なって誰が誰の子か分からなくなる。指が滑って違う人につないでしまっても、元に戻せない。家系図アプリでよく聞くその2つの困りごとに絞って作りました。 ■ 人数が増えても自動で整う 名前と続柄を入れるだけで、世代ごとに自動できれいに並びます。婚姻・養子・再婚・複数世代をまたぐ複雑な構成でも、線を自分で引き直す必要はありません。 ■ 間違えても、Undoで元に戻せます 誤って違う人とつないでしまっても、ボタン一つで元の状態に戻せます。「全部やり直すしかない」ということはありません。 ■ 実の親と、育ての親と。両方書けます 養子縁組があるご家庭でも、実親・養親の2組をそのまま記録できます。無理に1組にまとめる必要はありません。 ■ 作成・編集は人数無制限でずっと無料 何人分でも、何本の家系図でも、無料のまま作成・編集できます。広告も表示しません。 ■ 親族から届いたファイルも、そのまま追加できます 親戚が作った家系図ファイルを受け取ったら、新しい家系図として取り込めます。今お使いの家系図は変更されません(非破壊)。取り込みも無料です。 ■ 渡すとき・残すときだけ、買い切り¥600 ・ファイルとして書き出す:全体、または選んだ人より上の代だけを書き出して、親族に共有できます ・PDF出力:家紋を添えて、印刷して残せる形で書き出せます 一度の購入でずっと使えます。月額料金はありません。作成・編集・人数無制限・複数ツリーの保有・取り込みは、購入しなくてもすべて無料のまま使えます。 ■ データは端末の中だけに保存されます アカウント登録もログインも不要です。入力した内容は外部のサーバーに送信しません。日々の自動バックアップを保持し、書き込み中にアプリが落ちてもデータが壊れない設計にしています。 ■ こんな方に ・親戚の集まりで家系図を作ることになった方 ・以前ほかのアプリで作った家系図が、線が重なって読めなくなってしまった方 ・養子縁組や再婚があり、家族構成をそのまま記録したい方 ・誤操作で作り直しになるのが不安な方 ※ 生年月日は「昭和10年頃」のような自由な書き方にも対応しています。正確な日付が分からない先祖の記録にもお使いいただけます。

About

Zipda

Zipda is a light, fast archive app. Open, browse and preview ZIP, RAR, 7z and TAR archives, and unzip ZIP and TAR in one step. Big archives stream straight to storage, so there is no waiting. Everything happens on your iPhone: no account, no tracking, no advertising SDKs. WHY FILENAMES BREAK, AND HOW ZIPDA FIXES IT Archives made on Windows often store filenames in a regional code page instead of Unicode, so on an iPhone they arrive looking like "ÇѱÛ.txt". Zipda works out the original encoding right on your iPhone — CP949/EUC-KR, Shift_JIS, GB18030, Big5 and more — and shows the most likely original name. A banner tells you which encoding was detected, and one tap lets you override it if you disagree. Already extracted a folder full of mangled names somewhere else? The Repair File Names tool renames the whole folder back in one pass, shows you a before-and-after preview first, and never touches file contents. FORMATS • Extract: .zip, .tar, .tar.gz, .tar.bz2, .tar.xz; .rar, .7z, .lzh, .alz (Pro) • Create: .zip; AES-256 encryption (Pro) • Password-protected .zip opens whether it uses legacy ZipCrypto or AES (Pro) • Multi-part sets extract in one pass — pick the first part and Zipda finds the rest (Pro) BUILT FOR BIG ARCHIVES Zip64 archives past 4 GB, tens of thousands of entries, split volumes: Zipda streams them instead of loading them into memory. The progress view shows real bytes, real entry counts and a time estimate that matches reality. Cancel stops immediately and cleans up the half-written files it made. WHEN AN ARCHIVE IS DAMAGED A truncated download or one bad sector usually means the whole archive fails to open. Zipda extracts every entry it can still read, then tells you exactly which entries it skipped and why — so you get the 900 photos back instead of nothing. MADE FOR IPHONE • Got an archive in Mail, a messaging app or the Files app? Share it to Zipda and it opens • Choose where the files go in the Files app, or look inside first and pull out just the one file you need • Select photos, videos or files in Photos or the Files app and compress them right from the share sheet • Follow a long extraction on the Lock Screen and in the Dynamic Island • Move files between your iPhone and a computer on the same Wi-Fi, using the computer's browser and a PIN • Dynamic Type and VoiceOver labels throughout • 12 languages, switchable inside the app without restarting PRIVACY Nothing leaves your iPhone. No account, no analytics, no advertising SDKs, and the app makes no network requests of its own. Zipda's App Store privacy label is "Data Not Collected" — because there is nothing to collect. Zipda Pro (optional) Zipda Pro is optional and comes in three plans: a monthly or yearly auto-renewable subscription, or a one-time lifetime purchase. All plans unlock the same features on iPhone, iPad and Mac and can be shared with your family through Family Sharing. Pro unlocks extracting RAR, 7z, ALZ and LZH archives, split archives and password-protected archives; extracting Korean, Japanese and Chinese filenames with their original names; the filename repair tool; and creating 7z, password-protected and split archives. Opening, browsing and previewing any archive, plus everyday zip and tar work, do not need Pro. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period; manage or cancel anytime in your Apple Account settings. If a subscription ends, Pro features lock again; the lifetime purchase does not expire.
