Cooljugator (https://cooljugator.com/ru) is a verb conjugation app for many languages, including Russian! This is great for a refresher on how to conjugate verbs you already know, or if you run into a new type of verb that you’re not sure about. Because it’s just for verbs, you don’t have to sort through a dictionary entry to find this part of the word. It’s quick and easy!
It shows a grid, for which you can change the settings, and it does this for the future, present, and past tense forms of verbs.
It also gives example sentences for context, along with English translations.
The website even provides trickier parts of Russian verbs such as participles and the aspect pair!
