Then I moved to a 12 Plus and it still worked fine. Now with a 15Pro Max I find the flash setting is not working. While Longines no longer is making the VHP GMT, they should be updating the app to work with consecutive generations of the phone. The technology is so basic (compared to Bluetooth) so why can’t they keep this updated. ### 1/5 — Camera does not focus on iPhone 14 pro *2023-07-03, version 1.2.1* The idea of the app is amazing but the camera does not focus on the watch dial to be able to work for the flash feature for the auto tune sync. Had this been the main reason I bought the watch I’d be furious but it wasn’t. It can be done manually which is very easy but the app feature is pretty cool, should it work in future! ### 1/5 — No updates of the app, not really compatible with new iPhone *2023-06-19, version 1.2.1* No updates of the app and not really compatible with the new iPhone when need to set time using the camera. KM_T ### 1/5 — Outdated with no Support *2023-04-25, version 1.2.1* I bought the watch and this application does not work as it is more than 3 years old and most of the phones nowadrys are not compatible with it. I would appreciate it if you could suggest any alternative applications that I can use to sync my watch with my phone. Or at least update your software. What a waste of money to buy the watch. Thank you! ### 3/5 — Does not support the camera on iPhone 14 Pro *2022-12-30, version 1.2.1* App works fine on my wife’s iPhone 13 but the camera will not focus to sync the time on a iPhone 14 Pro ### 1/5 — 対応機種が少なすぎOSのバージョン記載もない *2021-05-08, version 1.2.1* このアプリはコンクエストVHP,GMT（以後 コンクG）にとっては生命線のアプリであり、これがないとまともに日付、時刻設定すらできない。そんなこととは知らずに、コンクGを買ってしまった。 　ところがこのアプリは正式に対応している機種として10数モデルしか記載がないし、国産のスマホは全滅状態。ちゃんと動作する保証がない状態で国内でコンクGは販売されている。 　少なくとも販売時に手動での日付時刻合わせには制限があり、スマホアプリを使わないとそれらを完全に設定できないことは記載なり説明なりすべきであり、その上でアプリが、日本で多く使用されている機種のサポートをすべきと思います。 　また、サポートしているOSバージョンすら記載がないのは、アプリをまともにメンテする気がないように思われます。 　ロンジンといえばスウォッチグループの名門といっても良いブランドですが、どうしてこんなことになっているのでしょうか。 　時計の生命線がこのアプリしかなく、メンテにも不安があるとはお粗末と思うのは考え違いなのでしょうか。 ### 1/5 — Does not support Newfoundland time (GMT -3:30) *2019-12-16* Big disappointment for an otherwise very smart watch. My Seiko Astron can manage this, is it just a matter of updating the app, or is this a hardware limitation? ## Most critical reviews (10 lowest-rated) ### 1/5 — 意味がない *2025-11-19, version 1.2.1* カメラでピントが合わない。合わせられない。バグだらけで、使用できません ### 1/5 — Camera. Very. Bad. *2025-08-27, version 1.2.1* Bad ### 1/5 — Abandoned App *2025-03-12, version 1.2.1* I am stunned…after paying $900 and enjoying the VHP GMT, Longines turned their backs on this app and its customers… ### 1/5 — iPhone 15 pro max 촛점이 인 맞음 *2024-11-26, version 1.2.1* 촛점이 맞춰지지가 않아서 엡이 제대로 시간 맞춰지지 않음. 업데이트 요망 ### 1/5 — Getting Away *2024-11-05, version 1.2.1* I’ve had two VHP timepieces and started with iPhone 8. Then I moved to a 12 Plus and it still worked fine. Now with a 15Pro Max I find the flash setting is not working. While Longines no longer is making the VHP GMT, they should be updating the app to work with consecutive generations of the phone. The technology is so basic (compared to Bluetooth) so why can’t they keep this updated. UPDATE: Still no update and the app does not work at all. I recall when this was released, the argument for using flash instead of Bluetooth was that no one knew for how long Bluetooth would remain an active standard. They didn’t take into account evolving mobile software and flash mechanisms. ### 1/5 — App can’t detect watch face on new iPhones *2024-08-25, version 1.2.1* Fix the app to detect watch face. ### 1/5 — Don’t bother *2024-08-16, version 1.2.1* Like everyone else says - it doesn’t work. Eventually the camera flashes, but the time does not set. The app says “success”. Brilliant craftsmanship… ### 1/5 — Doesn’t work *2024-04-02, version 1.2.1* It’s a shame to have such a primitive App for such a luxury brand. It simply doesn’t work. ### 1/5 — Needs to update *2024-01-03, version 1.2.1* Needs to update to new phones ### 1/5 — Abandoned app *2023-09-20, version 1.2.1* App has not worked in almost 2 years, longines have no interest, have contacted them several times now, and no reply. Simply not good enough for what is supposed to be a premium Swiss watch brand. It is a shame that the after sales is third rate at best. ## Most praised reviews (10 highest-rated) ### 5/5 — vhp gmt 시계에서 잘됨(아이폰16프로) *2025-10-26, version 1.2.1* 크라운 길게 누르고 12시 리셋 상태에서 전송하면 잘작동 ### 5/5 — App works fine *2024-06-26, version 1.2.1* I use an iPhone 15 pro and the app works fine. You set your times in the app, point the camera to the watch (ensuring the watch face fills the circle, and yes it’s doesn’t focus). Press take photo and the app will “modulate” the flash to program the watch. The flash will appear to be “flickering” but this is normal. ### 5/5 — 시간 세팅이 편해요 *2024-05-15, version 1.2.1* 지역 변경 시 이 앱을 이용하면 성확하게 세팅됩니다 ### 5/5 — Love this watch and app *2020-03-06, version 1.2.1* I do a lot of traveling and use GMT watches. The VHP GMT by far is the coolest GMT available. The flash setting works perfectly. Super cool and useful. Love this app, great job! Works fine with my iPhone 11 Pro, though the latest officially supported iPhone is the X. ### 5/5 — Great. Does the job *2020-02-10, version 1.2.1* It simply works: which I think is the best comment for a tool app ### 5/5 — 時刻合わせに最適 *2019-11-23, version 1.2.1* 機械式時計を合わせる際、秒数がデジタルで出るのでとても重宝しています。 昔のiOSでは、時計のアプリで秒数が出てた記憶がありますが、いつの頃からかなくなってました。 無料なので最高ですね。 ### 5/5 — 좋아요-~ *2019-03-14, version 1.0.2* 너무 편하고 좋아요~ ### 4/5 — Cool design for setting the time *2026-03-10, version 1.2.1* I think the watch is great and this is a really novel way to set time. I’m a little sad the app is not longer being supported/updated. I still use the app any time I need to set up the watch. For the 17 pro the flash is on the other side so instead of lining up in the camera you line the 12 on the watch roughly to the led. Still works! It’s a bit finicky though. A more modern watch would likely use Bluetooth low energy, but there’s a lot of charm to the light flashing method. I hope this app is never taken down! I install it on every new phone I get. 4 stars not 5 because they should update it for new phones. 🙂 ### 4/5 — Marche bien *2025-04-17, version 1.2.1* Cette application marche bien. Il faut parfois s‘y reprendre à 2 fois, mais ça marche. Ma seule crainte est la suivante : la gamme VHP étant arrêtée, l‘application sera-t-elle encore disponible dans quelques années ? Et sinon, comment régler le fuseau GMT de la montre ? ### 3/5 — 古い機種にしか対応していない *2023-12-03, version 1.2.1* iPhone15 Proなどの複数のカメラを搭載したモデルですと、メインカメラでピントを合わせることができず、アプリが機能しません。iPhoneXRなどの古い単眼のカメラ搭載機種であれば問題なく使用できます。こういった古い機種を持っている人も少なくなってきているので、最新モデルに対応してほしいです。 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
