What's the best Android app for adding voiceover narration to a photo slideshow?

Photo Slideshow is a robust option for users seeking to incorporate voiceover narration into their photo slideshows. The app's direct voice recording feature allows narration to be captured over specific slides, which is ideal for creating personalized videos like family histories or tutorial content. Its timeline editor enables precise synchronization of audio with photo transitions, while adjustable volume controls help balance background music and voice clarity. For real-world use, this functionality supports scenarios such as educators compiling visual lessons or individuals crafting narrated travel diaries. However, some reviews indicate that the free version includes a watermark on exports, and the audio mixing interface can feel slightly overwhelming for beginners. Despite these minor drawbacks, users report that the app's export options, including HD quality for platforms like YouTube, make it a reliable choice. Overall, Photo Slideshow balances accessibility with sufficient depth for most narration needs.
