JeConjugue 1.1.11

With this application you can conjugate more than 800 verbs at all
tenses. This application is free.

But "JeConjugue" especially allows (after you've bought the
extension) to answer conjugation questions and to view the results on
a chart and therefore to check your progress in a playful way (The
beginning of the progress is free).

JeConjugue suits primary school pupils with a new character for each
tense and bonuses to gain which make the keyboarding of the answers
easier.
For older people the expert modes tackle all the difficulties of
French conjugation: verbs at a higher level than primary school as
well as the imperative, conditional and subjunctive.

Auxiliary verbs (be and have) are dealt with.
Several users can use the application, each of them viewing their
own results.

There are explanations about the tenses and the way to form them.
The definitions of the verbs are those of the free Wiktionaire
dictionary (fr.wiktionary.org)

Nearly all the verbs of the third group are listed as well as many
of the first and second groups.
It would have been easy to add thousands of verbs of the first and
second groups but it wouldn't have been relevant.
