| Lite version | lite.html — no external libraries, no animations, opens instantly, shares progress with the full version |
Lite version
lite.html is a stripped-down build for slow devices and slow networks. It has no CDN
dependencies (no Tailwind, Font Awesome or Google Fonts), no animations and no glass effects,
so it loads instantly and keeps CPU load low.
| Full | Lite |
|---|
| Files | index.html + Tailwind/Font Awesome/Google Fonts | lite.html + own CSS |
| Size | ~180 kB translations, heavy visuals | 28 kB translations, no external requests |
| Trainer / Dictionary / Flashcards / Mistakes | yes | yes |
| Letters / Prepositions / Sprint / Exam / Stats / Achievements | yes | — |
Progress is shared: both versions read and write the same verbTrainerSettings and
verbTrainerErrors localStorage keys, so favorites, statistics and mistakes are the same
wherever you train.
Switch manually at any time: Настройки → Производительность in the full version, or the
footer link in the lite version. On first visit the app measures the device (cores, RAM,
GPU, network, battery, reduced motion and measured FPS), scores it from 0 to 100 and offers
the lite version once if the score is below 65 — then never again for 14 days. Choose
Больше не предлагать to disable the check permanently.
