A running cadence app by Alterras LLC
Onbeat is a training aid, not a medical device or a coach. You own your data, we own the app, and the app is provided as-is. Running carries risk and Onbeat plays audio in your ears while you do it — stay aware of your surroundings. By using Onbeat, you agree to these terms.
These Terms of Service ("Terms") are an agreement between you and Alterras LLC, a New York limited liability company ("Alterras", "we", "us", "our"). They govern your use of the Onbeat Running mobile application for iPhone and Apple Watch ("Onbeat" or "the app"). By downloading, installing, or using Onbeat, you agree to these Terms. If you do not agree, do not use the app.
Onbeat is a running cadence app. It plays a metronome you run in step with, runs structured interval workouts, and offers a multi-week program that raises your cadence gradually. It records completed sessions to Apple Health. It is a general fitness and training aid.
Consult a qualified healthcare professional before starting or changing a running programme, and especially if you have or suspect any of the following:
Stop running immediately and seek medical attention if you experience chest pain or pressure, severe shortness of breath, dizziness, faintness, or sudden or worsening joint or muscle pain.
Stay aware of your surroundings. Onbeat is designed to be used with headphones while you run outdoors. Audio in your ears reduces your ability to hear traffic, cyclists, and other people. Keep the volume low enough to hear what is around you, obey all traffic laws, and do not use Onbeat in any situation where reduced hearing or attention could cause harm. Do not operate your phone while running in traffic.
Changing your running cadence changes the load on your body. Increase it gradually, and stop if it hurts. You are responsible for judging what your body can do.
From version 1.1, Onbeat is free to download and free to use, with every feature, on iPhone and Apple Watch. There is no trial, no purchase to unlock anything, no subscription, and no recurring charge. If you want to support the work, you can leave an optional tip in the iPhone app. Full tip terms are in Section 14 (Tip Terms) below. Earlier versions are covered in Section 14.
All tips are processed by Apple through the App Store. Alterras does not receive, store, or have access to your payment information. For pricing, refunds, or billing issues, contact Apple Support directly at getsupport.apple.com. Apple's refund policy applies to all Onbeat tips and purchases.
Your workouts, session history, and settings are stored locally on your device. Completed sessions are written to Apple Health with your permission, and on Apple Watch, Onbeat reads heart rate and active energy while a workout is running. No data ever leaves your device to us. There are no accounts, no ads, no analytics, and no data collection. For the full detail, see the Onbeat Running Privacy Policy.
You agree to use Onbeat only for personal, non-commercial training purposes. You will not:
Onbeat, including its code, design, visual elements, audio tones, voice cues, workout structures, and all related content, is owned by Alterras LLC and is protected by copyright, trademark, and other intellectual property laws. These Terms grant you a limited, non-exclusive, non-transferable license to use the app for personal purposes. You do not acquire any ownership rights.
The workouts and session records you create in Onbeat belong to you and remain on your device.
ONBEAT IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY LAW, ALTERRAS DISCLAIMS ALL WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.
We do not warrant that Onbeat will improve your running form, cadence, speed, endurance, or any other outcome, or that its audio timing, recorded workouts, or measurements will be accurate or complete.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, ALTERRAS LLC AND ITS OWNERS, EMPLOYEES, AND AFFILIATES WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF ONBEAT.
OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR YOUR USE OF ONBEAT IS LIMITED TO THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR TEN U.S. DOLLARS ($10), WHICHEVER IS GREATER.
Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you.
You agree to indemnify and hold harmless Alterras LLC from any claims, damages, losses, or expenses (including reasonable attorneys' fees) arising out of your misuse of Onbeat, your violation of these Terms, or your violation of any applicable law.
You may stop using Onbeat at any time by deleting the app from your devices. We may suspend or terminate your access to Onbeat if you violate these Terms. Upon termination, sections 5 through 13 survive and remain in effect.
These Terms are governed by the laws of the State of New York, without regard to its conflict of law principles. Any dispute arising out of or relating to these Terms or your use of Onbeat will be resolved exclusively in the state or federal courts located in New York, and you consent to the personal jurisdiction of those courts.
We may update these Terms from time to time. If we make material changes, we will revise the "Last updated" date below and, where practical, provide notice within the app. Your continued use of Onbeat after changes take effect constitutes acceptance of the updated Terms.
From version 1.1, Onbeat is free, with every feature. If you want to support the work, you can leave a tip in the iPhone app at the level you choose: A coffee, A generous tip, or Pay it forward.
A tip unlocks nothing. Each tip is a consumable in app purchase through Apple: a one off payment, not a subscription, that you can repeat as often as you like. Every feature is already yours whether you tip or not.
Payment is charged to your Apple Account at confirmation of purchase. There is nothing to renew and nothing to cancel. Prices are set in the App Store, may vary by region, and the price shown in the app at the time of the tip applies. Apple's standard refund policy applies to all tips; request a refund at reportaproblem.apple.com. Alterras cannot issue refunds directly.
Purchases in versions before 1.1. Versions of Onbeat before 1.1 start with a 7 day free trial that the app grants on your device. It needs no payment and does not turn into anything paid; when it ends, the paid features lock until you buy. They then offer a one time purchase at the price you choose. Every tier unlocks the same app, does not renew, and gives permanent access on Apple devices signed in with the same Apple Account. There is nothing to renew or cancel. Versions before 1.1 may also give a period of free access for submitting the optional in-app feedback form; this is not a purchase. The price shown in the app at the time of purchase applies. Apple's standard refund policy applies; request a refund at reportaproblem.apple.com. From version 1.1 none of these are offered, every feature is free, and nothing you bought is taken away.
Onbeat is licensed, not sold, to you. These Terms grant you a limited, non-exclusive, non-transferable license to use the app for personal, non-commercial purposes, subject to these Terms and to Apple's standard Licensed Application End User License Agreement (EULA), which is incorporated here by reference. Except as expressly granted, all rights are reserved by Alterras LLC, and the app is provided without warranty as described in Section 8.
