Store reviews

What readers say.

Five-star reviews from the App Store and Google Play, as they were written.

I love reading. That’s how I became fluent in english and french. I’m currently learning german and needed a tool to help me translate my german books in french without having to use a dictionary or a translating app. I love how the words you save are getting memorized so that when you come upon one the translation is already there and you understand easily. This is the first time that I pay for an app ever because it simply deserves it. You can also import your own books and read them.

This is a great application for improving both reading level in a language, and with text to speech can also be used to improve one's ear for the language. of course vocabulary as well. They reached out to me for feedback and personally helped me with some issues I was having, which was a very positive experience.

Simply Fluent makes learning through reading incredibly easy and enjoyable. I especially love that the books are organised by language level, as finding the right books when starting a new language is usually frustrating, but this app removes that problem completely. The whole experience feels very smooth and intuitive. The daily challenges helped me to build a consistent learning habit. Highly recommended for anyone learning/wanting to learn a new language!

I’ve started using simply fluent and what can I say, it’s simply effective. Reading helps me keep my Spanish while simultaneously learning new vocabulary and I absolutely love it. 10/10 recommend!

I have been learning languages ever since I can remember and speak 3 fluently. Simply Fluent is clearly the best I tried so far - reading is the best way to fully embrace any new language and the UX is designed in a way that makes it really pleasant to go back regularly.

I’ve been using this app for a few weeks now and it is great.I love reading and I’m also learning Spanish so it’s the perfect combo. You can translate words you don’t know and then memorise them later with a flash card game. Highly recommend
