High-quality vocals with your iPhone or iPad

Spire for iOS combines award-winning iZotope audio processing with multi-track recording to make importing a beat, layering vocals, collaborating with your producer, and sharing songs easier than ever. When your iPhone is your mobile vocal booth with automatic Soundcheck and seamless cloud project sharing, recording high-quality vocals is possible anywhere.

• Import a beat and write lyrics

Get started by importing your beat. Easily write and develop your lyrics directly in the Spire app and have them front-and-center while you record.

• Automatically set your levels and tone

When you run Soundcheck in Spire before you record, it will identify voice or an instrument, set your levels, and sculpt your tone. Vocals stand out in the mix through automatically adding compression, saturation, and EQ—powered by tech from the Vocal Assistant in iZotope's Nectar plug-in.

• Layer vocals and mix your tracks

Building a song with Spire is fast and intuitive. Easily capture lead vocals, overdubs, ad-libs, and more by just hitting record. You can edit out unwanted parts from any track with the trim tool. To mix, drag track icons up or down to adjust volume and left or right to pan.

• Collaborate with artists and producers

Text or email a project link to anyone from the Spire app and they can preview your song, export mixdowns, download individual tracks to edit in a DAW, or open in Spire to add tracks of their own. Cloud sharing lets you work with producers and collaborators no matter where you are.

• Share with your fans

If you’ve finished a song in Spire that you’re ready to show the world, you can publish your songs to SoundCloud, Instagram, and more directly from the app. Add artwork or a video to your project to make it your own before posting for your fans.

Magic demo machine!

As a songwriter, I’ve always wanted a quick and easy way to demo a new song. Most of the time, I’ve just used my iPad to capture it. And if I had the time— I’d fire up Garage Band. If I really wanted to share to a wider audience, I’d work through it on my Protools setup. But now, Spire helps me make a quick and easy demo in my living room that sounds darned close to a studio version. The more I use it, the better I get and the better I sound. It does feel like a magic little box. The mic check dials in the levels, the effects sound nice and clean and above all it takes me minutes— not hours! My biggest wish would be to improve the ability to punch in to fix a guitar clam. It’s close to impossible so I usually try to get a complete and acceptable take before moving on to vocals. Punching in a vocal isn’t hard because there’s usually a dead space that I can come in on. I hope iZotope is still working on this little gem because it would be great to be able to at least add an easy dissolve to smooth a punch in. But hey, I actually couldn’t be happier with this thing.

Hey! Thanks a ton for the review! We couldn't be happier to know that Spire is a magic demo machine for your musical experience. Your suggestion about punching in with guitars has been forwarded along to the rest of the team and we are always working on improving the app (and the Spire Studio). Send us an email at if you have any other thoughts or questions -- thanks again!

I do best when recording solo. This app has allowed me to do so with exceptional quality and it’s so user friendly. The things I would love to see in the future would be: basic effects. I would love to be able to add some basic reverb or chorus effects to eliminate the need to take up precious track space with multiple vocals. Maybe like 3 effects? That’s all you really need. Also, I’ve seen in other recording software a “solo” option meaning I can isolate one track to listen to to find that one later I want to delete without having to individually muting a bunch of tracks to find the one I want to delete. I see you’ve put the option to add an icon to tracks to help distinguish what instrument is featured on each track but that’s not enough when it comes to layering vocals etc. soloing a track would be much quicker. Anyways, great app and great quality! Thanks!

Just Missing a few things

Really love this device and what it can do. However there are two main things i would like to see on the app side of things. 1st is the ability to mix tracks down to a single track like you could do on the old 4/8 tracks and then have another 7 tracks to keep adding with. 2nd is some level of post production, I understand the device is aimed at musicians who want to cut thru all the hang ups of traditional recording etc but you guys really have something here that could be much more than that. Im not saying to go crazy but maybe a 4 band eq for starters and then add some basic easy stuff that others have mentioned. Again not looking for pro tools just some tools to tweak and shape the sound a little more. Add it as an upgrade pack in app purchase or whatever i would definitely be interested in something like that keep up the good work and looking forward to some future updates

Hey Tymebombproductions! Thanks for this review -- we want to let you know we have seen your suggestions and they have and will continue to influence the direction we go with Spire. You are correct in that a "mobile DAW" isn't exactly what the developers are going for but we strive to make the right choices and try to be careful with any compromises that ever need to be made. Since it's been a while we would like to hear what you think of how Spire has developed and progressed since then - send us an email to if you have any other thoughts or insight. Thanks again!
