Wokabulary: $1K a month, self-reported in 2023 vocabulary learning app

Wokabulary is a flash card learning app for managing and practising foreign-language vocabulary. Its $1K a month was founder-reported on the Indie Hackers product page (not independently verified), as of September 2023.

What it actually sells

Wokabulary is a flash card vocabulary learning tool for foreign-language learners. It lets users manage and practise their own vocabulary. The app covers school, evening classes, and self-study. Its learning structure sorts new and difficult words for more frequent review, while old and easy words appear less often.

How it charges

Wokabulary Unlimited is a subscription plan. The site says that subscribing directly supports continued development. The product is also available as a free download for iPhone, iPad, and Mac.

Where customers come from

Wokabulary is available through the app store and as a free download for Apple devices. The site describes the app as available for iPhone, iPad, and Mac. It also links vocabulary lookup on macOS and iOS with translation through DeepL.

What stands out

Wokabulary manages multiple languages and alphabets, with quiz modes for flashcards, spelling, and listening comprehension. It syncs words and learning progress between iPhone, iPad, and Mac. Dictionary lookup and DeepL translation are integrated into the app.

From the official site

Are you learning a language in school, evening class, or in self-study?

Words get automatically sorted in learning levels. New and difficult words are asked more often — old and easy words less often.

Where it sits in the data

Wokabulary's $1K a month is higher than 40% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, the buyer would be language learners using school, evening classes, or self-study. The demand is specific: people need a way to manage vocabulary and practise it across Apple devices. Distribution would come from app-store discovery and word-of-mouth among learners.

Building the product would require reliable vocabulary management, spaced repetition, progress syncing, quiz modes, dictionary access, and translation support. The hard parts include device compatibility, account and data handling, language coverage, and ongoing support. A new entrant would also compete in the app store.

Verdict: Needs real work.

One thing to take from it

Wokabulary combines a subscription product with a free Apple-device download. Its product surface connects vocabulary management, spaced repetition, quizzes, syncing, dictionary lookup, and translation.
