The apps in detail
Boatpass
Covers five licences – SBF See, SBF Binnen, UBI, SRC and LRC – in a single app. Each catalogue unlocks via one-off purchase, no subscription. Includes exam simulation, mistake training and per-category progress. New to the market and accordingly few ratings.
Best suited for: Anyone taking several licences who does not want a subscription.
Bootspruefung.de
The market leader: on sale since 2013, over 900,000 customers by its own account, and the broadest licence coverage here. All official exam questions are free to use; theory texts, full offline use and PDF downloads sit behind Pro. Progress syncs with the website course.
Best suited for: Anyone wanting the widest licence coverage plus a companion online course.
Sailbyte
Three separate apps for SBF See, SBF Binnen and SKS with an adaptive study plan, flashcards and AI feedback. Premium is a monthly subscription – one per licence. SBF See and Binnen work offline, SKS needs a connection. Answer explanations are announced as coming.
Best suited for: Anyone taking exactly one licence who accepts a subscription.
SBF Binnen
The most carefully built learning mechanic in this field: classic Leitner boxes either automatic or manual, plus a dedicated mode for questions you are unsure about. Includes a textbook explaining every question, multiple-choice tips, all exam knots and a progress statistic. Runs entirely without an internet connection.
Best suited for: Anyone who wants to understand SBF Binnen rather than memorise it.
SBF-Fragen
From publisher Delius Klasing, with a spaced-repetition box, exam simulation on original papers, offline learning and cloud sync across devices. Neat touch: if you already hold a licence, you only get the questions you still need. The free version shows only a subset of the catalogue.
Best suited for: Anyone who already holds a licence and only needs the remaining questions.
Sportbootführerschein Binnen
Completely free, no ads, no user tracking, no extra permissions. The full official catalogue – base, inland and sailing supplement questions – on a spaced-repetition principle: every question must be answered correctly five times. No explanations, no frills.
Best suited for: Anyone who only needs SBF Binnen and wants to spend nothing.
SBF Binnen app for Android
All six apps are on Google Play. The strongest free option is Sportbootführerschein Binnen by Matthias Wimmer: over 100,000 downloads, 4.9 ★ from 772 ratings, no ads, no in-app purchases, no tracking. The full official catalogue including sailing supplement questions is there, learned on a spaced-repetition principle.
What it lacks is explanations for the answers. If you want to understand rather than memorise, SBF Binnen by Ralf Goritz (4.8 ★ from 567 ratings) serves you best: a textbook for every question, Leitner boxes either automatic or manual, a dedicated mode for uncertain questions and all exam knots. Bootspruefung.de and SBF-Fragen also supply theory texts.
Boatpass is on Google Play as well. The SBF Binnen catalogue costs €9.99 as a one-off, or €16.98 together with SBF See. Trying it is free.
SBF Binnen app for iPhone and iPad
On iPhone, three of the six apps are available to you: Bootspruefung.de, SBF-Fragen and SBF Binnen by Ralf Goritz. All three contain the full catalogue including sailing supplement questions.
The free Wimmer app and Sailbyte are Android exclusives. Boatpass is not in the App Store yet – the iOS version is in development. To start on an iPhone today, the three apps above are the choice.
What Boatpass does – and what it does not
Transparency note: Boatpass is our own app. That is precisely why we list the prices, features and ratings of the alternatives in full – including where they beat us. The figures come from the public Play Store listings and the vendors’ own websites.
