About Which Language App
Which Language App is an independent comparison site. It answers one question, which language app fits a particular person, by putting every app's published price, language list, free tier and features side by side, with the source and read date next to each figure.

Why this site exists
Choosing a language app is a subscription decision, usually forty to two hundred dollars a year, and the comparison pages that rank for it are mostly opinion pieces that hide the numbers. This site inverts that: the numbers come first, in a table you can sort and filter, and the writing explains what the numbers mean for a specific kind of learner.
The comparison is deliberately narrow. It covers consumer apps and tutor marketplaces for adults learning a second language on their own time. It does not cover school licences, corporate training, or exam-prep publishers, because a person picking one app for themselves does not compare against those.
Every row is built the same way: read the vendor's own pricing page and help centre, write down what it says, record the URL and the date, and leave a blank where the vendor publishes nothing. There is no testing of the apps behind these pages and none is claimed; what you get is an honest reading of what each company says about its own product, organised so you can compare it.
How the comparison is made
Prices are read from each app's own pricing page as shown to a visitor in the United States, in US dollars, and every price on this site carries the date it was read. Where a page shows a promotional price next to a regular price, the regular price is the one used for ranking and the promotion is noted separately.
Tables sort by a neutral criterion, price per month at annual billing by default, and can be re-sorted by any column. An app's commercial relationship with this site never changes its position, its inclusion, or the words used about it. That rule is enforced in code: the ranking functions read price and feature data only and have no access to referral status.
A feature is recorded as present only when the vendor states it on its own site or app-store listing. Unknown is written as unknown. Where the vendor says nothing about, for example, offline mode, the table shows a dash rather than a guess.
The site does not run lessons, score apps out of ten, or award badges. Verdicts on comparison pages are written per use case, for instance a traveller with six weeks, a learner aiming at a B2 certificate, or someone who wants a human tutor, and each verdict points at the rows that justify it.
Who runs it and how it is funded
Which Language App is operated by Adrian Nutiu, an independent publisher based in Romania who runs a small portfolio of comparison and reference sites. There is no editorial team behind these pages beyond the operator and the tools used to keep the dataset current.
The site is funded by affiliate links. When a reader follows a link to an app and buys a subscription, the app may pay this site a commission, at no extra cost to the reader. Which apps do this, at what rate, is listed on the affiliate disclosure page, and links that can earn a commission are marked as sponsored in the page code. As of 2026-09-06 no affiliate programme has been joined and every outbound link is a plain, untracked link to the vendor.
The site shows no display advertising and sells no placements, rankings or reviews.
Corrections and contact
If a price or feature on this site is wrong, or a vendor has changed its pricing page, write to hello@whichlanguageapp.com with the app name, the page on this site, the correct value and the vendor URL that shows it. Corrections are checked against the vendor's own page and applied with a new read date.
Vendors are welcome to send updated pricing or feature information. The same standard applies to them as to readers: the fact must be visible on a public page the vendor controls. Private statements are noted but cannot replace a public source.
