About Which Language App

What this comparison is for

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: a pick for each kind of learner comes first, then every app's numbers 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 that a person buys for themselves or for their child, and the finder on the home page answers adults learning a second language on their own time. Separate guides cover apps made for children and what the same apps sell to employers for their staff. It does not cover school licences, training companies that are not apps, or exam-prep publishers, because a person picking one app does not compare against those.

Prices and features are checked against app pricing pages and help centres. Missing information stays unknown.

How the comparison is made

Prices are checked against each app's own pricing page as shown to a visitor in the United States, in US dollars, and every price we cover carries the date it was checked; the date of the newest check is in the footer of every page. Where a page shows a sale price next to a regular price, the sale price is the one used, because it is what you would have paid that day, and the regular price is shown beside it.

Commercial relationships do not affect the recommendations or where an app appears.

A feature is recorded as present only when the app states it on its own site or app-store listing. Unknown is written as unknown. Where the app says nothing about, for example, offline mode, the table shows a dash rather than a guess.

The scores are made in the open. The eight criteria, what counts for each, how the facts and the reviews are combined, and when an app gets no pick are written out on the methodology page. 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 points at the rows that justify it.

How an app is scored, and what a pick means, is on the methodology page.

Who runs it, and where the money comes from

Which Language App publishes this independent comparison. No app maker owns or controls the comparisons, and the methods and source records used to keep them current are public on this site.

Corrections and contact

If a price or feature on this site is wrong, or an app has changed its pricing page, write to [email protected] with the app name, the page on this site, the correct value and the URL that shows it. Corrections are checked against the app's own page and applied with a new check date.

App makers 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 app maker controls. Private statements are noted but cannot replace a public source.
