### 5/5 — Best Solution Out there!

*2025-12-21, version 4.8.3*

Best app to use your ipad as an external monitor..

### 4/5 — 잘 쓰고 있었는데 갑자기 화면 설정이

*2025-10-21, version 4.8.3*

어플이 약간 불안정하기는 하지만 그래도 자리 차지를 많이 하지 않고 문서 읽기용 서브 모니터로 잘 사용하고 있었습니다. ios26으로 업데이트하고 나서 세로로 꽉찬 화면이 안 되는데요 ㅠ 사이트 문의하기로 메일 넣었는데도 아직 답변을 받지 못했습니다. 얼른 해결되기를 바랍니다. 문서 읽기 너무 힘들어요.

### 5/5 — Pretty good

*2025-08-02, version 4.8.3*

Works well without much latency. Good for making use of my old iPad before getting a proper second monitor.

I’m connecting my iPad Pro to my windows laptop; had a bit of issues with my GPU driver’s optimizations causing problems. What shocked me the most was how good the customer service was; I can count on one hand how many times I’ve had constructive conversation with customer service and I can say for certain these guys are good.

### 1/5 — Não funciona no macOS... o site diz que funciona! Quero meu dinheiro de volta!

*2025-04-29, version 4.8.3*

Não funciona no macOS! Quero meu dinheiro de volta!

### 1/5 — Не ведитесь!

*2025-01-10, version 4.8.3*

У меня последняя версия ipad pro и мощный ноутбук асус на windows 11. Купила это приложение и оно не работает. При подключении спустя пару минут оно виснет. Невозможно управлять с айпада ноутбуком. Все виснет, тормозит. Выкунула деньги.

### 5/5 — 보조모니터 앱은 이게 최고입니다.

*2024-05-13, version 4.6.8*

Splashtop, glidex 등 여러가지 앱을 다 써봤는데 이 앱이 안정성이 제일 뛰어나네요. 항상 잘 쓰고 있습니다.

### 1/5 — 환불 안 되나요?

*2024-03-30, version 4.6.8*

랩탑에서 인식을 못 하는 데요? 아무리 지우고 다시 깔고, 해도 인식 연결이 안되요. 케이블에 필요사양이 있나요? 특정케이블만 되는 건가요?

### 4/5 — 화면 전환이 빠르면 화질 열화가 발생

*2024-03-10, version 4.6.8*

아이패드 M1 Pro 11인치 사용중(120헤르츠)이며 컴퓨터는 엔비디아 3070 그래픽카드 사용중입니다. 데스크탑 모니터는 60헤르츠 사용중이고요. 일단은 Twomon se를 활용해 윈도우 화면을 아이패드에 띄우면, 처음에는 연결이 선명하게 잘 되는데 웹페이지를 빠르게 스크롤하거나, 1인칭 게임에서 화면을 휙휙 돌리는 등 화면 전환이 빠른 경우 아이패드 화면에서 화질 열화가 발생하고 화면을 전환하지 않고 멈춰도 한참 남아있습니다. 그러다 화면 전환을 안 하고 가만히 있으면 잠시 후(10초 내외) 화질이 돌아옵니다. 마치 e-ink로 동작하는 이북이 리프레시 안 하면 화질이 계속 나빠지는 것처럼 화질 이 나빠지는 것 같아요. 이게 왜 그런 걸까요? 이것만 안 그러면 너무 잘 쓸텐데 이것 때문에 환불해야하나 고민중…

### 5/5 — works well (windows10, 2024.2.23)

*2024-02-23, version 4.6.8*

was worried initially that it wont work as smoothly but functions real well. I dont feel too much lag. Works with c-ports too.

### 5/5 — 너무 좋아요 제발 오래오래 서비스 해주세요

*2024-02-15, version 4.6.8*

얼마전에 맥북에서 갤북으로 넘어와서 아패랑 맥북 유니버설컨트롤기능을 쓸수없너서…  아이패드를 갤탭으로 넘어가야하나…고민중에 이앱을 깔고 사옹해보니 
완전 잘되네요 유선이라그런지 딜레이도 진짜 거의없고 
아쉬운건 화질인데 이건뭐 어쩔수없을거같고 ㅜㅜ
진짜 오래오래 서비스 부탁드립니다.
