Terms of Use

Last updated: 9 November 2026

These terms apply when you download or use Beep Test: 20m Shuttle Run, an app from Itworked Systems, a company registered in Türkiye. By using it, you agree to them. If you downloaded the app from Apple's App Store, Apple's standard license agreement applies as well.

Using the app

We give you a personal right to use the app on devices you own or control, including for testing the runners you coach or teach. Please don't copy, resell or redistribute it. We may change or improve features with updates.

Your health and safety

The beep test is a maximal effort test. Warm up first, run on a flat, non-slip surface with enough space, and stop if you feel dizzy, in pain or unwell.
If you have a health condition, or you are unsure whether you should do a maximal test, ask a doctor first.
If you test other people, you are responsible for their safety, for choosing a suitable place and for any permission you need from them or their guardians.
The app gives general fitness guidance. It is not medical advice.

What the app can and cannot do

The app is independent. It is not affiliated with and not approved by any police service, fire service, armed force, school programme or test publisher. The standards it shows (for example UK police and armed officer levels, and fire rescue levels) are published figures shown for practice only. The organisation's own test decides, and its rules and audio may differ from this app.
VO2 max is an estimate from a published formula, not a medical measurement, and it can be wrong for you.
The 15 m police-style test matches the published UK 5.4 standard for levels 1 to 5; above level 5 it follows the common audio, not an official table. US Air Force HAMR shuttle targets in training plans are practice targets only; the app has no HAMR test mode.
Beeps and speech come from your phone's audio and text-to-speech. Timing can be affected by your device, Bluetooth speakers and system settings, and we cannot promise that the sound will play on every phone in every situation.

Beep Test Pro

Every test, with full sound and voice, results with estimated VO2 max and standards, and the last 5 results in History are free. Beep Test Pro unlocks group testing, training plans, practice runs at any level, the full history with a progress chart, CSV export and starting a test at any level. It is sold through Apple or Google, under their terms, as a one-time purchase. There is no subscription. The price is shown in the app before you buy.
Pro stays unlocked. On a new phone, tap Restore purchases on the Pro screen or in Settings, signed in with the same Apple Account or Google account.
If Pro were ever lost, your results stay saved on your phone.
Refunds are handled by Apple or Google under their refund rules. This does not limit any rights you have under the law of your country.

The app is ours

The app, its design, sounds, icon and name belong to Itworked Systems. Some parts are open-source software and fonts used under their own licenses.

Our responsibility

We provide the app as it is, and cannot promise that it will always work on every phone or be free of errors. As far as the law allows, we are not responsible for damage or losses that come from using it, such as injury during a test or a result that differs from an official test. Nothing in these terms limits responsibility that the law does not allow us to limit, or your rights as a consumer.

Changes to these terms

If we change these terms, we update this page and the date at the top.

Law

These terms are governed by the laws of the Republic of Türkiye, and disputes go to the competent courts and enforcement offices of Türkiye. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you can take a dispute to the courts or consumer bodies there.
