Persian Subtitle: Dual Subs shows every line of a video twice: in its own language and in Persian, at the same moment. Learn a language, follow a film, or help family members who read Persian, without stopping to translate.
WHAT IT DOES
• Dual subtitles: the original line on top and the Persian line under it, in time with the video
• YouTube videos: paste or share a link and watch with two-line subtitles
• Direct video links (MP4, MKV and more), played in the app's own player
• Videos with no subtitles: the speech is turned into text, then translated into Persian
• Turn the original line or the Persian line on and off at any time
• Choose the text size, position and color
• English, German, French, Turkish and many more languages
• No account or email needed to start
PLANS
• 3 free days to try everything
• Then Persian Subtitle Premium: monthly or yearly auto-renewing subscription
• Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings.
PRIVACY
No account needed: open the app and start watching. Signing in with an email code (no password) is optional and only lets you use your subscription on your other devices. We keep only what the service needs: your subscription, simple usage counts, and your email if you add one. When a video has no subtitles, its audio is sent in pieces only to turn the speech into text, and it is not stored.

Ratings & Reviews
A quick welcome on first launch: pick Persian or English, see how dual subtitles work, and try a free sample video. Plus a clearer home screen with an "Open YouTube" button.
معرفی کوتاه در اولین باز شدن: انتخاب فارسی یا انگلیسی، دیدن اینکه زیرنویس دوگانه چطور کار میکند، و امتحان یک ویدیوی نمونهی رایگان. بهعلاوهی صفحهی اصلی واضحتر با دکمهی «باز کردن YouTube».
