No subscription. Ever.

Why one-time

A vocabulary app is not a service you should have to keep paying for

Learning a word doesn't come with a recurring cost, so looking it up shouldn't either. A subscription only makes sense for something that keeps costing money to provide — new content every week, servers, live support. A dictionary and a flashcard trainer don't need any of that: the dictionaries ship with the app, the Leitner scheduling runs entirely on your device, and there's no account system to maintain on a server somewhere. Charging monthly for that would be charging for nothing.

Ads pay for continued development instead, and they're kept out of the way on purpose: they can appear while you're browsing the dictionary or your list, and never once you start a flashcard or spelling session. If you'd rather not see them at all, the one-time purchase removes them for good.

Ownership

Your words are yours

There's no account and no login — your dictionary lookups, saved words, and training history live on your device, not on a server tied to a login you have to keep paying to access. You can export your entire list to a plain JSON file at any time, straight from Settings, whether you're backing it up, moving to a new phone, or just want a copy you can read yourself. Nothing about Wordwren is designed to make your own data hard to leave with.

No pressure

No streak-guilt

Wordwren won't push you a notification about a broken streak, and there's no counter designed to make skipping a day feel like a loss. Spaced repetition already tells you exactly which words are due — that's enough signal on its own, without turning your vocabulary practice into a guilt mechanism engineered to keep an app's engagement numbers up.
