Apart from other resources I use "English Grammar in Use" mostly to practice tenses.
You can either get a book or the app.
I'd suggest this app (Android & iOS) by Cambridge University and this one (Android & iOS) by Oxford University. Both can really be of great help and if you only want to know everyday grammar these are the best options.
Both are books made into apps. If you want, you can get the printed versions.
Cambridge's and Oxford's websites can help you too.
