NOTE:
Please note the following if you have enabled automatic logging in the background (indicated by the blue frame in the app):

Continued use of GPS in the background can drastically reduce battery life. In our experience, however, a full day of sailing can be done with it, nevertheless don't forget the 12V charging cable ;-)

### 5/5 — Super praktische Logbuch-Lösung

*2026-05-11*

Ich verwende die Software jetzt seit vier Jahren auf einem Segelboot und bin sehr zufrieden.

Die Grundfunktionen sind intuitiv zu bedienen, und man findet immer wieder neue Möglichkeiten, da die Software permanent weiter entwickelt wird. 

Absolute Empfehlung!

### 5/5 — Excellent

*2026-05-09*

Well apparently I’ve been using it for almost three years! 
It’s a fantastic tool for recording almost everything I do on the boat. Florian has steadily improved it over time and to be honest it’s well worth the subscription. 
Only problem I have is my wife gets annoyed when I grab my phone every time we change from motoring to sailing or anchored. No complaints from a very happy user. 
Haven’t tried printing anything yet having always transferred to a written record but I’ve a feeling printing may well be the way to go. 
Keep up the good work.

### 5/5 — Highly recommend…

*2025-10-23*

Another passage over the last two weeks has reinforced how useful this app is.
The developer responds promptly to my queries - often a clarification of the detailed workings.

### 5/5 — Sensationelle App und ausgezeichneter Support

*2025-10-23*

Die App bietet wirklich alles, was das Herz begehrt und wenn irgendwo einmal Schwierigkeiten auftauchen, die auch einfach nur mit falschen Einstellungen oder dem verwendeten Gerät zusammenhängen, dann gibt es einen super qualifizierten, hilfsbereiten und mega schnellen Support! Besser geht wirklich nicht!

### 5/5 — Geniale App für Segler

*2025-09-07*

Gestern bin ich von einem Segeltörn zurück gekommen, bei dem ich zum ersten mal die App ernsthaft als Logbuch verwendet habe. Die letzten 23 Jahre habe ich mein Logbuch immer auf Papier geführt. Aus meiner Sicht ist das mit dieser App nicht mehr notwendig. Die Protokollierung ist super, jeder Kurswechsel wird vermerkt, Wetterdaten werden automatisch erfasst. Wie gut die App bei Blauwasserfahrten ohne Zugang zum Internet funktioniert, werde ich kommendes Jahr testen. Auch bei einem Verlust des Schiffes bin ich noch unsicher, ob das Logbuch 1. als Dokument dient, 2. ob ich es dann noch abrufen kann. Bisher bin ich super glücklich und der Preis ist mehr als ein Schnäppchen, für das, was sie leistet. Vielen Dank an den oder die Entwickler für die tolle Arbeit. Was ich mir noch wünschen würde (vielleicht habe ich es noch nicht entdeckt) wäre eine Funktion, in der ich die Logbücher der einzelnen Törns verwalten kann. Ich würde die App wieder kaufen und zusätzlich ab und an mal einen Kaffee spendieren.

**Developer response:** Vielen Dank! Melde dich bitte mal bei mir wegen deinen Fragen.

### 5/5 — Super App

*2025-09-03*

Seit Jahren eine gerne genutzte App für Segeltörns. Wenn die App einmal richtig eingestellt ist, was Törndokumentation angeht, Autoeinträge, Quellen für die Wetterdaten, etc. hat man eine große Erleichterung, kann schnell und problemlos Einträge machen. Sie schreibt die Streckenführung, Kursänderungen selbstständig mit. Am Ende hat man alles dokumentiert und zusätzlich saubere Auswertungen der Tagesstrecken oder des Gesamttörns. Kann sie nur empfehlen!

### 5/5 — A really useful app !

*2025-08-23*

A great app for use on motorboat or yacht I would imagine. I use this on a motor cruiser and it is perfect for daily log use. 

The AI generated daily summary makes a fantastic record for future reading :)

### 5/5 — Genialer Helfer

*2025-06-15*

Ich nutze die App seid 4 Jahren in denen sie mir unaufdringlich im Hintergrund zu Diensten ist und mein Logbuch führt. Früher habe ich Daten stündlich von Displays auf Papier gebracht. Das passiert heute vollautomatisch, das meisten kommt direkt aus dem NMEA Feed. Bei Internetverbindung wird das dann auch noch über den Server auf z.B. das iPhone verteilt und auf dem Server vorgehalten. Damit ist es mit entsprechender Datensicherung besser aufgehoben, als es die Information auf Papier im Havariefall wäre.

Im Vergleich zu einem deutlich teureren Wettbewerber schätze ich die Unaufdringlichkeit der App. Die reine Aufzeichnung passiert in Hintergrund, mehr notiere ich im Normalfall auch nicht. Ist doch etwas Prosa zu ergänzen, ist das iPhone schnell zur Hand und der Text diktiert oder getippt bzw das Foto geschossen. 

Das letzte Update hat noch mal eine große Lücke geschlossen, indem jetzt auch die Füllstände meiner Tanks, die Betriebsstunden des Motors automatisch mit erfasst werden können. Allerdings gehört schon einiges dazu, dies über die regular Expressions zu konfigurieren.
Über die Motordrehzahl den Status von Segel zu Motor und zurück mit erfassen zu lassen, wäre noch der Hammer, aber sicherlich nicht trivial. 

Insgesamt spürt man, wie viel Gedanken in der App stecken, so dass sie weitestgehend intuitiv im Hintergrund ihren Dienst versieht.

### 5/5 — Sehr gut durchdachte App

*2025-05-05*

Die Logbuch-App nutze ich seit mindestens 6-8 Jahren. Sie ist einfach zu bedienen und deckt dennoch sehr viele komplexe Szenarien ab. 
Der Support durch den Author/Entwickler ist großartig und zeitnah, klasse!
Seit das Tool auch die Synchronisierung mit mehreren Geräten kann, bin ich wunschlos zufrieden. Wenn ich doch mal einen Verbesserungsvorschlag habe, kommt immer häufiger eine Beschreibung, wie's geht was ich vermisse. Sprich: alles schon da!

### 5/5 — Nicht einfach nur eine weitere Logbuch App!!

*2024-10-24*

Zugegeben, 17,99€ für eine einfache Logbuch -App mag einem teuer erscheinen, aber dieses App ist wesentlich mehr Wert wie ein Kinobesuch oder ein Schnitzel mit Pommes!! Ich behaupte von mir ein gewissenhafter Skipper zu sein und diese App ersetzt dir nicht das führen eines Logbuches, aber es unterstützt dich bei allen Aufgaben. Egal ob es Position, Wetter, Wind oder die An-/Ablegezeiten sind, die App hilft dir dabei. Besonders liebe ich die Tracking Funktionen. Egal ob es die Karten Ansicht in der App oder die Live-Tracking-Funktion über das Internet, wo du Freunden und Verwandten per Internet-Link dein aktuelle Position und deinem Track mitteilen kannst, ist gigantisch. Das wichtigste kommt aber zum Schluss. Egal ob du Probleme mit der App, Wünsche oder Anregungen hast, oder einfach mal eine Frage hast, Florian hilft dir weiter!! Vielen Dank Florian, weiter so!

New Features, Bug Fixes, and Improvements:

- If an NMEA RMC sentence had no COG/SOG (no value between the commas), it was incorrectly treated as zero; now it is correctly left out.

### 2.84 — 2026-04-06

With this update, I’d like to share a few personal thoughts. I’m switching the payment model for NEW users from a one-time fee to an affordable annual subscription. New users will have plenty of time to test every feature without restrictions before they pay. For EXISTING CUSTOMERS who have already bought the app, nothing changes. Subscribing is optional and helps fund future development.
I hope many existing users will also choose to support the app voluntarily so that future features aren’t limited to new subscribers. Thank you very much in advance!

New Features
- Select multiple Quick Manoeuvres and change or set their type and mode. The mode stored in each Quick Manoeuvre is now also taken into account.
- New voting option to suggest and rank future features.
- The UISplitView on iPad now expands for a wider view.
- The weather icon for calm conditions now looks different from the no-clouds icon.

Fixed bugs
- If no results appeared in the Log tab after filtering, the filter/search bar would disappear and could not be reset.
- The search bar now stays in the right place when you open the app and switch to Tab 1.
- Logbook entries now sort correctly after a time zone change.
- Hidden icons in the Log tab are now fully hidden.
- Translations and errors in the implementation of offer codes from the previous update
