Create a Soundtrack to your Life with Filmstro. Powered by Filmstro’s innovative audio technology, Filmstro for mobile enables you to create professional Soundtracks for your Videos straight from your iPhone. Create music in real time and share on your favourite social channels.


Choose from 15 free music themes or 16 additional themes for a broad range of professional Soundtracks.

Mood slider

Our music is called a theme because you can customise each piece and make it suit the action in your Video. With the mood slider you can change the intensity of each piece to increase or decrease depending on what’s happening in your film.

Volume mixer

Use the volume mixer to either make the music a subtle underscore underneath the audio in your video, or maybe turn it all the way up so it’s more like a music video!

Record & share

When you’ve chosen your theme, simply tap the record button and use the mood slider to create your perfect Soundtrack, then share on your favourite social channels.

What's New

Version 1.1.1

You can now remove the 30-second limit and the watermark from your exported videos!

Ratings and Reviews

Very Slick!

At first I thought that it was just changing the volume when I moved the slider, but it's so much more than that. The slider brings in lots of different sounds and instruments, very clever indeed! Totally changes the mood of the videos. Lovely clean UI too, very slick app.

A doddle!

This was recommended by a friend and has exceeded expectations. A doddle to use. I've just added an epic, rousing soundtrack to a video of my son's first steps by sliding my thumb around. Should be standard on iMovie or iPhone imho. Love it

Amazing!!! A must have app.

Absolutely amazing. Simple to use and amazing results. You can time the tempo/ambience to produce amazing emotion provoking videos using one simple control. WARNING: YOU WILL END UP BUYING THE FULL FAT DESKTOP APP!
