Wer ist bereit über 200€ für eine Anker-App auszugeben??? Als Abo würden die Funktionen 100€ pro Jahr kosten; das ist Wucher. Funktionen sind ok aber der Preis ist lächerlich. ### 4/5 — Overall, great anchor alarm! *2025-12-28* We love this anchor app and really want to give it five stars. As full time cruisers that were at anchor for two years straight in the South Pacific this was our go to anchor alarm. It has as the bells and whistles that are important to us. In 90% of the cases we’re satisfied with the free version. In rare instances we want the premium features and at a price of $25 for the year we felt it was worth it. We subscribed in March, but unfortunately we have not been able to unlock the premium features. A couple times over the past nine months we wanted to access premium features, unable to do so we reached out to customer support (at least twice) and our message fell into a black hole and there was no response. It’s possible it’s user error on our part (what email did we use? It was so long ago!), but we can’t work that out without getting a response back from Zenkou. Again, this is a fantastic anchor alarm, even at the fee base version. We just wish we could contact support. ### 3/5 — Gut aber nervt. *2025-08-25* Benutze es das zweite Jahr in Folge. An sich tut das was es soll, ist überschaubar und ausreichend. Online sind auch die Landkonturen sichtbar. Leider wird das Bildschirm zu 1/3 von Nötigung eingenommen. Es geht um personalisierte Datensammlung. Das Tracking wollen sie am liebsten IMMER eingeschaltet, und sich registriert und angemeldet haben. Das lässt sich nicht ausblenden. Nötigung nervt! ### 2/5 — Frustrating *2024-10-16* I have paid the 100$ for lifetime but it still tells me I need to subscribe for the features. We have paid for the live and yet it goes off constantly even though our boat has never moved. **Developer response:** Thank you for sharing your feedback. We apologize for any inconvenience you’ve encountered, and we’d be happy to clarify how the features work to make sure your subscription is fully set up. The "LIVE" function includes a battery-saving feature: if your boat remains stationary, the app will send a single location point to conserve battery. Continuous tracking will automatically resume as soon as movement is detected. For any issues with your subscription, please reach out to us at SUPPORT@ZENKOU.COM . Our team is here to help and will prioritize your case to ensure you can immediately enjoy the app’s full functionality. ### 1/5 — No funciona fácilmente *2024-06-13, version 2.4.7* Ya pagué varias veces, no logro hacerlo funciona se. Me pide dos ctas, dice q es gratuito , pero no entiendo como, de modo q con otro e mail cree otra cta y volví a pagar, aún así no funciona ### 5/5 — Test Zenkou *2024-05-30* Très bonne application Facile d’utilisation Testée en Thaïlande, aux Baléares et maintenant en Grèce avec la même précision ### 5/5 — Excellent 👍 *2024-04-28* Excellent 👌 **Developer response:** Hello! Thank you so much for your excellent review! We're thrilled to hear that you find Zenkou Anchor Watch helpful for safe anchoring. Your support means a lot to us. Best regards, The Zenkou Team ### 5/5 — Exelente *2024-04-05* Muy buena app para saber si estás garreando super recomendada **Developer response:** ¡Hola! ¡Muchísimas gracias por tu comentario! Nos alegra saber que te gusta nuestra app y que la recomiendas. Seguiremos trabajando para ofrecerte la mejor experiencia. ¡Saludos! ### 4/5 — Licenses never work *2024-02-02* As a standalone app this is a great alarm and it works very well. It’s easy enough to set and forget. However, I bought two licenses so I could watch my boat at anchor and get alarmed when it’s dragging. The app constantly forgets that I have two licenses and keeps popping up with license purchase page. For that reason alone I would say this app is not usable as that was the reason I got this app. Other anchor apps I have cost a lot less and work as well. Edit: After contacting support and describing the error message the team fixed the code within a few days and the app doesn’t request me all the time to subscribe again. On rare occasions it still pops up. **Developer response:** Thank you for taking the time to share your feedback. We appreciate your positive remarks regarding the functionality and reliability of our app. However, we sincerely apologize for the inconvenience you've encountered with the subscription issue. To resolve this issue promptly, we kindly ask you to contact our support team directly at support@zenkou.com. We are ready to assist you and address any concerns you may have with the app. Your feedback is crucial to us, and we are committed to ensuring that your experience with our app meets your expectations. Thank you for your understanding, and we look forward to assisting you promptly. ### 5/5 — Boat Anchoring *2024-01-23* Very easy to use anchor alarm system. Gives me flexibility in adjusting my anchor location. I have tryed others and find this is the easiest to work with. Dorla V **Developer response:** Hello Dorla, Thank you for your wonderful review!

Dommage qu il faille payer pour s apercevoir de cela.. ### 1/5 — Erro/ problema *2025-08-23* Não funciona !! ### 1/5 — Application complètement inutile, pas aboutie, avec de nombreuses défaillances … à fuir ! *2025-07-22* Pas d’essai gratuit, je comprends maintenant pourquoi ! Personne ne l’achèterait si on avait la possibilité de l’essayer gratuitement avant. L’alarme se déclenche sans raison, après 24h le signal disparaît donc pas possible de l’utiliser sur un mouillage long, pas intuitif, cher etc… rien à voir avec les bonnes applications existantes ! Je l’efface et ne l’utiliserai plus. ### 1/5 — Be careful - DO NOT TOUCH *2025-06-17, version 2.4.32* You charged me without permission. 60 euro. There is no way to access and there is no way to cancel. How can you be still in business? Please return my money back. You should not be on apple. ### 1/5 — Suscription not works *2025-04-07, version 2.4.29* We paid two suscriptions and is not working. We cannot be a leader neither follower ### 1/5 — Prezzo esagerato *2024-09-04, version 2.4.17* Costa troppo per quello che offre. La sto utilizzando da più di due mesi e mi sta creando un sacco di problemi. Parte l allarme da solo senza nessuna motivazione pur essendo nel raggio. Altre app, anche gratuite sono molto superiori. Sono pentito di averla acquistata. Mi sono fatto incantare dal fatto che fosse parte di navionics. Cercate altrove. ### 1/5 — Engañoso *2024-08-10, version 2.4.16* Si es una app gratuita no puede ser que constantemente te aparezca obligacion de subscripcion. Apple no lo debería permitir ### 1/5 — Cher pour pas grand chose *2024-08-04* Contrôle a distance pas pratique du tout. Historique introuvable. Fausses alarmes dont on ne peut pas trouver les raisons. Je regrette d’ avoir pris les options payantes. **Developer response:** We are sorry to hear that you have encountered issues with our app. Your feedback is valuable to us and helps us continually improve our services.

A la semana me cobraban por las dos versiones al mismo tiempo. Cobran dos veces por la misma app. Mucho cuidado. ### 1/5 — Nicht nutzbar stürzt ab *2024-07-22* App stürzt nach dem öffnen sofort ab. **Developer response:** Es tut uns leid zu hören, dass du Probleme mit unserer App hast.

Combined with Navionics map, it has been extremely useful, allowing to set an alarm if you drag your anchor beyond a given radius. I found effective and accurate. The main challenge is manipulating your phone and the windlass at the same time when dropping the anchor. A matter of practice. And if you have questions the WhatsApp msg is swiftly answered and the problem I had was solved. On that basis seriously considering subscribing to support the app. Fabrice **Developer response:** Hi Fabrice—thanks a ton for the five-star rating and for championing Zenkou Anchor Watch! We’re thrilled the app (paired with Navionics) is making your anchoring smoother, even with the windlass–phone juggle. To everyone reading: our crew is available 24 / 7. Whether you’d like expert anchoring pointers, have feature ideas, or simply want to share a cool cruising story, message us on WhatsApp or email SUPPORT@ZENKOU.COM and you’ll get a speedy, real-human reply. Happy sailing and safe anchoring! ### 5/5 — Boat Anchoring *2025-01-27* Very easy to use anchor alarm system. Gives me flexibility in adjusting my anchor location.

Un fan servicio post venta ### 5/5 — Great app for checking position and monitoring when ashore *2024-06-19* 5 * ### 5/5 — Va genial ! *2024-06-17, version 2.4.7* La uso con el Apple Watch cuando bajo a tierra y así mantengo un ojo en el fondeo. Les contacté un domingo porque no encontraba cómo cambiar el sonido de la alarma y me respondieron súper rápido. ¡Recomendada! ### 5/5 — Hervorragender Support und zuverlässige Funktionen *2024-05-30* Ich habe den Support kontaktiert, um herauszufinden, wie ich die Vibration des Alarms ändern kann, und sie haben mir sofort geholfen. Der Alarm funktioniert präzise und gibt mir ein sicheres Gefühl, wenn ich an Land gehe. Die Wettervorhersage für den Ankerplatz war in dieser Woche, in der ich die App getestet habe, sehr genau. Sehr empfehlenswert. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
