Drill My Language Skill: keep your learning momentum with beyond-the-basics lessons. Practice your English, Spanish, French, Italian, German, Dutch, Polish, Russian, Ukrainian. A basic language course may get you to A2 or B1, B2 level - but probably won't take you further. What's worse, without constant practice your language proficiency will decline. With the free DMLS app you can maintain your fluency and improve your reading and listening skills, by building upon what you already know with continuous practice. Key features that set us apart: * Learn from context: This app is not about starting from scratch; it's about building upon what you already know. Engage with tens of thousands of diverse sentences to refresh known words and grammatical concepts and learn - sometimes infer - new ones. * Any language pair: Exercises "from" and "to" any of the supported languages: English, Spanish, French, Italian, German, Dutch, Polish, Russian, Ukrainian. * Variety of Exercises: Translating sentences both ways: to and from your target language. Listening and reading comprehension tasks. Constructing complete sentences from standalone words, either by listening to the target language's audio without seeing the text, or by translating from your known language. * Instant translations: Stuck on a word or sentence? Use our instant translation feature to translate a single word or the whole sentence, and keep practicing. * Smart Error Tracking: No one's perfect, and mistakes are a part of learning. The app intelligently tracks your errors, prompting you to revisit and master those tricky sentences later. * Your own favorite sentences Bookmark interesting sentences in a list to review at a later point. * Easy registration Full functionality with an anonymous account. Premium features: We offer a premium subscription that would make your language practice even more enjoyable: * Focus on specific exercise types Just reading (no sound required) or just listening: chose the exercise type that feels the most appealing right now. * Dual Language Learning: If you want to learn a language that is similar to the one you somewhat know, but don't know quite well. Or just up for a brain teasing, to challenge and enhance your cognitive skills? Learn two languages simultaneously! Add translations of all sentences to a third language - the one you have a good command of - and learn two languages at once. * Better translations Translations right in the app and explanations of what the specific word means in the specific sentence. Pretty neat! * No ads (obviously). There aren't that many to begin with, but with premium there's 0, so infinitely fewer.

Verdict

The call

DMLS and byHeart both sit at 5.0 stars, but that hides the real split: 100% of byHeart's written reviews are positive against 0% of DMLS's. byHeart also leads on ads (none vs shown). DMLS's advantage is update cadence (weekly vs fortnightly) and ratings volume (5 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
