My review
أسوء برنامج لتسريع الصوت
اعلانات فالمنتصف تغطي عالصوت بدون حتى ما توقف التسجيل ..
وأحيانلً الإعلان لا يغلق والبرنامج بيعلق
سيئ جداً لا تحملوه ..
This app is so bad with forced adds
Which cover the sound of your record at once
I couldn’t fasten any record without missing many parts of it ..and play it back to hear it
So bad don’t download it anyway.
