Looking for Personal Lexicon / Dictionary software

Question

I'm trying to find a personal lexicon/dictionary/language study/flash card program - preferably one that makes allowances (ie has a place to enter) all of the forms of a word (noun declensions, verb tenses etc).

The closest thing I've been able to find is Personal Lexicon which lets you add these forms, but never asks you about them.

iVocabulary 3 which is based on ProVoc also looked very promising but not quite there.

I'm certain I've seen software that does this (and by certain I mean I might have imagined it), does anyone know of a program or have any suggestions?

Just to recap, I am hoping to find language learning / lexicon software that:

1. Lets you create your own entries.
2. It allows for the great number of forms Latin has for it's conjugations and declensions etc.
3. I can use software on the following platforms (in order of preference) - MacOS, iPadOS, Windows, Java/Web apps etc.

Answer 1

Do try Anki: https://apps.ankiweb.net/ I have been using it for 5+ years to study/improve my knowledge of languages and to prepare for exams. It has an impressive toolkit, and additionally supports audio (quite useful for the purpose), as well as images/videos and LaTeX (speaking of exam preparation). It is available on all platforms and is free (with a notable exception of iOS where it's $25, I believe, for whatever reason).
