The full present tense and the top 100 verbs are free forever. Pro gives you all 50 levels and 18 tenses, 2,500+ verbs, and Smart Quizzes that focus on what you need to work on. It's around $5 a month on the annual plan, or about $10 a month if you'd rather pay monthly. If you'd prefer to pay once, there's a lifetime option at roughly three times the annual price.
Prices vary by country and platform (because of different sales taxes and app store commissions). The upgrade screen in the app shows your exact price, and https://app.ellaverbs.com/pricing shows web prices in your currency – a little lower there, as there's no app store commission.
New users get a 5-day free trial, no credit card required. And through our Give Back programme, we give free Pro access to anyone who can't afford it, because we never want cost to get in the way of learning. Details in-app or email support@ellaverbs.com.
