Lando is a free, open-source translation dictionary application that aggregates commonly used translation services without any advertisements. Built with Flutter, it provides a clean and fast user experience for quick word lookups.
The author was frustrated with startup ads on mobile translation apps. When searching for words frequently and briefly, the actual lookup takes only a few seconds, but opening the software often means waiting through at least 5 seconds of ads. That's why Lando was created - a completely free, ad-free alternative.
