Readle and Lingo7 both pair reading with native audio, but Readle gives you a fixed catalog of short graded stories in six languages, while Lingo7 lets you read full books, yours or ours, with a side-by-side translation, in 49 languages. Readle is a polished daily-habit app up to about B2; Lingo7 is for reading actual books and covers far more languages.

Readle (formerly Langster) is a well-made daily-reading habit. Its stories are consistently graded from A1 to B2 (C1 for German), each with native sentence-by-sentence audio, tap-to-translate and grammar notes, and the words you tap feed a flashcard deck. The design is clean and low on gamification, which makes it easy to read a little every day. For a structured on-ramp in one of its six languages, it is genuinely good.
Lingo7 is built for reading real books rather than a fixed catalog of short stories. You can read any book from the catalog or upload your own, with the original and a full translation side by side and native audio, and there is no B2 ceiling because you choose the material. Tapped words go to a spaced-repetition trainer and a Practice tab adds conversation. Lingo7 also supports 49 languages to Readle’s six, and it is free to start. Readle is the tidier daily-story habit; Lingo7 is for reading the books you actually want.
Lingo7 lets you read real books, ours or your own upload, with the original and a sentence-by-sentence translation side by side, native-narrated audio, and a tap to send new words to a spaced-repetition trainer. Free to start, in 49 languages.

No. Readle gives you a fixed catalog rather than letting you import your own EPUB or PDF. Lingo7 does let you upload your own books (EPUB, PDF, FB2, TXT, DOCX, HTML) and read them with a sentence-by-sentence parallel translation and audio.
Lingo7 supports 49 languages for reading. Readle supports 6 languages. If your target language is outside the major European set, check both before you commit, since coverage is where these apps differ most.
Lingo7 is free to start, with an optional premium subscription. Readle offers a rotating set of free stories, then Premium at about $10 to $15 per month. Both let you try reading before you pay. Prices are current as of July 2026; check each store listing for your region.
