ETenses

We explain each tense with a simple, animated timeline, where you can see how the past, the present, and the future are related to the time.
You will see that nothing seems complicated if you understand the time-flow logic.
For the practice part, we used the reinforcement learning technique. It will help you memorize tenses and verbs quickly and for a longer time.
The app contains the following tenses:

Present Simple
Present Continuous (Present Progressive)

Last but not least, the app has a list of all irregular verbs represented on a single page with a search, so you will be able to rewind the verb on the fly.
