Serval: Comprehensible Input Tracker

Counts the hours of comprehensible input you actually listened to, not the hours a video was open.

Serval counts the hours you spend listening to the language you're learning, so you can see your progress add up on the way to fluency. Listening to a language makes you better at it, but week to week you can't feel it happening. Serval keeps the count for you, accurately, and shows the work adding up. How it works - Choose the languages you already speak. Everything else counts. - Watch as normal on YouTube, Netflix and other video sites. - Serval listens to each video, works out its language and counts the time you actually listened. What counts - Time comes from the video player, so ads, pauses and skipping don't count. A tab in the background still does. - Videos in a language you already speak are recorded, but left out of your total. - If a video's language can't be identified, its time isn't counted. Nothing is guessed. Stay on track - A daily streak: listen 10 minutes a day to keep it going, and watch the days climb. - A daily goal, your total for today, and every video you listened to with its language. Tap the language to correct it. - Progress: all-time hours, your year as a rising line, a calendar of every day, and achievements. Share your year as a picture. Your data stays yours - Everything is stored in your browser. No account, no subscription. - Export a spreadsheet, back up to a file, or restore on another computer. - Audio is analysed on your computer to identify the language, then discarded. Nothing is recorded, stored or sent. Privacy policy: https://servalinput.com/privacy 105 languages, from Japanese and Spanish to Arabic and Thai.
