iPerfman measures network performance between your device and a compatible iperf3 server. Run TCP or UDP tests on iPhone, iPad and Mac. The free version allows three tests per day; Pro unlocks unlimited tests and advanced controls. Measure and investigate: - Test upload, download or both directions, with separate results for each direction. - Follow throughput in live charts. View UDP jitter and packet loss, TCP retransmissions, and round-trip time when those measurements are available. - Save completed tests with their configuration and interval results, then rerun a test or review its history. - Choose an IPv4/IPv6 interface when running a server, or listen on all interfaces. Unlock Pro with a monthly or yearly subscription, or a one-time Lifetime purchase. Pro adds unlimited daily tests, advanced iperf3 parameters, comparison of saved results, and full report export. The yearly subscription includes a seven-day free trial for eligible customers. Existing Lifetime purchases remain valid. iPerfman uses iperf3 3.22 through IperfSwift. A compatible server or second device is required for a network test; this is not an internet speed-test service. The Apple TV app uses a separate interface and has a different feature set.

CryptVault は、写真・動画・書類を「あなたの鍵で」暗号化して守る、プライバシー第一のファイル金庫です。 ■ アカウント不要ですぐ使える インストールしてすぐ、端末内に暗号化Vaultを作成。写真アプリやファイルから追加すると、その場で暗号化して保存します。クラウドも登録も不要です。 ■ 端末内で完結する暗号化 ファイルは rclone crypt 互換の強力な暗号(scrypt 鍵導出 + XSalsa20‑Poly1305)で暗号化されます。暗号鍵は端末の Keychain に保存され、外部に送信されません。 ■ 自分のサーバーにも“暗号化したまま” 必要なら WebDAV(Hetzner Storage Box、NAS、Nextcloud など)を設定して、暗号化済みファイルだけをアップロード。平文や鍵がサーバーに渡ることはありません。同じ鍵を使えば、複数の端末で同じVaultを読めます。 ■ 写真も動画もそのまま再生 サムネイル一覧、フルスクリーン表示、動画再生(mp4/mov に加え、webm/mkv/avi なども)に対応。 ■ 起動時ロック Face ID / Touch ID / パスコードで、アプリ全体をロックできます。 あなたのデータは、あなたのものだけ。CryptVault は、それを技術で保証します。
