Latin forms.
Confidently identified.

Every translation starts with the same question: what form is this? Formentrainer teaches you to answer it, step by step, instead of guessing.

Six forms, exactly like in the app. You get the explanation after every answer, because being wrong is only useful once you understand why.

Tip: you can answer with keys 14 and move on with Enter.

What's inside

Not another vocab app.

You can memorize vocabulary. Forms you have to understand. Formentrainer is built for exactly that, and nothing else.

Smart Training

The trainer remembers which forms give you trouble and brings them back at growing intervals, until they truly stick.

Ranks & XP

From Discipulus to Imperator. Every correct answer counts.

Verbs

Every tense, every mood, active and passive, plus nominal forms like PPP and PPA.

Nouns

a-, o-, consonant, i-, u- and e-declension. Case, number, gender.

Adjectives

Declension, comparison, and case-number-gender agreement with the noun.

Sentence constructions

Spot AcI, NcI, participial phrases and the ablative absolute in real sentences, not isolated forms. Exactly where translations usually fall apart.

25 lessons and every table

From the a-declension to the AcI: short lessons with a mini quiz, plus every paradigm table for reference. Forms are not pulled from a fixed list but built from the actual rules, so they hold up on the edge cases too.

Gute App

Diese App ist wirklich sehr gut: mein Sohn hat davor immer in Latein schlechte Noten geschrieben, obwohl er die Vokabeln eigentlich immer gut konnte. Er nutzt jetzt seit einiger Zeit diese App und seine Noten sind nun deutlich besser. Nun weiß ich, dass es nicht immer nur an den Vokabeln liegt sondern dass auch die Formen gut zu können wichtig ist.

Gute App

Ich finde die App echt gut und sie hilft auch für Schulaufgaben und so aber es wäre cool wenn man Am Anfang noch eine kleine Erklärung bekommen könnte :)

Frequently asked

Quick answers.

What year of Latin is this app for?

All of them. On first launch, the app asks how far along you are in Latin and which tenses, moods and declensions you've already covered. Anything you haven't learned yet is hidden, so you're never shown a form your class hasn't reached. Later, you can unlock more in the settings whenever you like.

Do I need an internet connection?

Only for the purchase. After that, everything runs offline: forms are built on the device following the actual rules, not fetched from a server. Handy on the bus, the train, or at school.

Is any data collected about me?

No. There's no account, no sign-in, no tracking and no ads. Your progress is stored exclusively on your iPhone.

Are the forms really all correct?

The app doesn't pull forms from a fixed list, it builds them with a grammar engine from stem and ending, including the edge cases. That engine is checked automatically against a test set with every release.

What if a form is ambiguous?

That happens constantly in Latin, portās can be "you carry" or the accusative plural of porta. In cases like that, the trainer accepts any correct reading and explains the other possibility too.

Does this replace Latin class?

No, and that's not the goal. The app trains one specific skill: identifying forms quickly and confidently. Exactly the part where most points get lost on exams.

Which iPhone do I need?

An iPhone with a current iOS version. The exact requirement is listed on the App Store page.

The next exam is coming, guaranteed.

Five minutes a day is enough. The trainer picks out the forms you don't have down yet.
