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.

영어 단어가 가물가물해도 괜찮아요. 스펠링 일부만 알아도, 한글 뜻으로도 찾을 수 있어요. 입력하는 순간 뜻과 품사를 보여주고, 어색한 문장은 살짝 짚어주는 영어 키보드. Plume Keyboard입니다. 영어가 완벽하지 않아도, 영어 문장은 끝까지 완성할 수 있도록 만들었습니다. ■ 영-한 사전 탑재 타이핑하는 동안 단어의 한글 뜻과 품사(명사·동사·형용사…)가 후보에 함께 떠요. 사전 앱으로 따로 나갈 필요 없이, 쓰면서 바로 확인합니다. ■ 퍼지 리졸브 — 스펠링이 가물가물할 때 철자가 헷갈리면 기억나는 부분만 치고 나머지는 *나 ?로 두세요. in*app*ate → inappropriate 처럼, 일부만 알아도 찾아냅니다. ■ 역방향 리졸브 — 영어 단어가 안 떠오를 때 영어가 생각나지 않으면 한글로 검색하세요. "사과"라고 치면 apology·apple·apologetic을 뜻과 품사까지 함께 보여줍니다. ■ 사전 카드 후보를 길게 누르면 뜻풀이와 영·한 예문이 담긴 사전 카드가 펼쳐집니다. 단어를 제대로 이해하고 쓰고 싶을 때. ◆ Plume의 두뇌, Laplace 엔진 Plume의 모든 추천과 경고는 자체 개발한 Laplace 엔진에서 나옵니다. 단순히 자주 쓰는 단어를 나열하는 자동완성과는 다릅니다. · 문맥으로 다음 품사를 예측합니다. "to" 뒤엔 동사 원형, 전치사 뒤엔 -ing처럼, 앞에 친 문장을 읽고 알맞은 형태를 골라줘요. · 한국어 화자가 자주 놓치는 문법을 짚어줍니다. 관사 누락, 셀 수 없는 명사에 붙은 a/복수형, 주어-동사 일치(I are, we writes) 같은 오류를 입력 중에 가볍게 경고합니다. (예: "buy new router" → "a/an·the 같은 관사가 필요해요") · 확신이 없으면 조용히 빠집니다. 애매한 제안으로 헷갈리게 하지 않아요. 잘못된 추천 하나보다, 깔끔한 침묵이 낫다고 믿습니다. · 문법 규칙은 항목별로 켜고 끌 수 있어요. be·have + 분사형, 조동사 + 동사원형, a/an 발음 맞춤 등 — 나에게 필요한 만큼만 도움받으세요. ● 당신의 입력은 기기 밖으로 나가지 않습니다 Plume은 '전체 접근 권한'을 요구하지 않습니다. Laplace 엔진의 변환·사전·문법 검사는 모두 기기 안에서 처리되며, 입력한 내용을 외부로 전송하지 않습니다. 인터넷 연결 없이도 동작합니다. 영어 메일, 메시지, SNS — 영어로 써야 하는 모든 순간에. 영어가 서툴러도 자신 있게 쓰세요. Plume Keyboard.
