UI sound effects for an app: what license do you need?

UI sound effects for an app are the tiny sounds behind your interface: a click when someone taps a button, a chime when a task is done, a buzz when a code is wrong. They are often under two seconds long, so they feel too small to need a license. They are not. Once a sound ships inside your app, it is copied onto every phone or computer that installs it, and Wavecrate's license table gives that use its own row. This guide shows where that line sits and how to cover a small app properly.

Wavecrate licenses royalty-free sound effects, including a kit of interface sounds, and every download comes with a license certificate and a code anyone can check on its verify page.

Why UI sound effects for an app need their own license

A short sound is still a recording. The U.S. Copyright Office's "What is copyright?" page lists sound recordings and computer programs among the works copyright protects, and it gives the owner the right to reproduce a work and to distribute copies to the public.

Think about what an app does with a click sound. It does not play once in a video that people watch. It is copied into your build, handed out with every install, and played every time someone taps. That is a different use from a sound in a YouTube video, so check that your license names it.

Find the word "apps" in the license table

On Wavecrate's plans and licenses page, the table for music and sound effects has a row called "Apps, games and software". Only Extended ticks it. Free and Standard do not.

The item pages say the same thing in plain words. Here is the license panel for Soft UI Click, "a clean, ready-to-drop interface sound for button and tap moments".

• Free: online videos and podcasts, with credit. YouTube, TikTok, Instagram, Twitch and podcasts.
• Standard, listed at $3 on this page: online content for one creator or business, no credit needed.
• Extended, listed at $9 on this page: paid ads, broadcast, apps, games and client work. It includes everything in Standard.

So for a sound that lives inside your app, the answer on Wavecrate is Extended, item by item. Paid licenses are not on sale yet (Wavecrate says "Purchases open soon"), so these are the listed prices for when sales open; items marked Free can already be downloaded with a free account.

Free interface sounds are not free for apps

This is where most app makers slip. Wavecrate's Interface sound kit is described as "Clicks, pops and chimes for apps, games and explainers", and five of its six items are marked Free. That word refers to the Free license, and the Free license covers online videos and podcasts with a credit line. Apps are not on its list.

So Soft UI Click is free to use in a tutorial video about your app, with credit. Inside the app itself, it still needs Extended, listed at $9 on its page. The same holds for Success Chime and Gentle Notification, which are also marked Free and also show Extended at $9.

The same check is worth doing on any site that offers free sounds. Read what "free" covers before a sound goes into a build.

Where Standard and Pro still help an app maker

Many apps come with videos: a demo on your own channel, a short clip for your product's social accounts, a walkthrough for new users. Those are online content for your own business, which is exactly what Standard covers, with no credit line.

Pro gives Standard licenses on the whole catalog. It is listed at $99 a year or $12 month to month, and it is not on sale yet. That suits the video side of an app project well. It does not cover the sounds inside the app, because Pro never gives Extended.

Two more uses sit with Extended in the table, and app makers meet both. Running a paid ad for your app is "Paid advertising". Building an app for someone else, for pay, is "Client work". If you hold Standard on a sound and later need it in the app, the pricing page says that, once purchases open, Standard can be upgraded to Extended for the difference.

A worked example: three sounds for a habit tracker

Say you are building a small habit tracker. You want three sounds: a soft tap when someone checks off a habit, a happy chime when they finish the day, and a short buzz when they enter a wrong code on the lock screen. You also plan a one minute demo video for your own channel.

Start on the sound effects page and filter by the Interface category (one of six, with 10 sounds each on 9 October 2026). Listen inside the Interface sound kit and pick:

1. Soft UI Click for the tap. Marked Free. Inside the app: Extended, listed at $9 on its page.
2. Success Chime for the finished day, "for win and complete moments". Marked Free. Inside the app: Extended, listed at $9.
3. Error Buzz for the wrong code, "for wrong and fail moments". Premium, so it has no Free license. Standard is listed at $3, but the app needs Extended, listed at $9.

Now the demo video. Because Extended includes everything in Standard, the three Extended licenses already cover those same sounds in a video on your own channel. If the demo also uses other sounds or music, those need at least the Free license with credit, or Standard.

Last, keep the three license codes in your project's notes, next to the file names you used in the build. Each code can be checked on the verify page, which shows who holds the license, for which item and what it covers. If a client, a partner or a reviewer ever asks where a sound came from, you can answer in a minute.

What the license does and does not give you

A license is permission, not ownership. Wavecrate's pricing page answers "Do I own the music?" with "No. You get a license to use it. We keep the copyright." The same goes for its sounds. You may use the sound in the ways its license describes, and no further.

Wavecrate has no separate license agreement page today, so the pricing table and each item page are the full description of what a license covers. If your use is not on them, do not assume it is covered.

Frequently asked questions

Can I use a free click sound in my app?

Only if its license names apps. On Wavecrate, sounds marked Free have a Free license for online videos and podcasts with credit, so inside an app they still need Extended.

Does Pro cover sounds inside my app?

No. Pro gives Standard licenses on the whole catalog, and apps, games and software are ticked only under Extended.

What license do I need for an app I build for a client?

Extended. Client work is ticked only under Extended in the table, and the item pages list it next to apps.

Does Extended also cover my app's demo video?

Yes, for the same sound. Extended includes everything in Standard, which covers online content for your own business with no credit line.
