Agreement to terms
By installing or using RatioRoll, you agree to these Terms of Service ("Terms"), our Privacy Policy, and the Apple Licensed Application End User License Agreement. These terms supplement the main H3llo H3llo Ltd Terms of Service.
RatioRoll is operated by H3llo H3llo Ltd, a company registered in England and Wales. Our registered address is 27 Wolseley Gardens, Newcastle upon Tyne, NE2 1HR, United Kingdom.
What RatioRoll is (and isn't)
RatioRoll is:
- A professional iPhone camera app
- A tool for recording 16:9 horizontal and 9:16 vertical video simultaneously from a single take
- A monitoring tool with LUT preview, false colour, and zebra exposure overlays
- A capture tool that supports Apple Log on iPhone 15 Pro and newer
RatioRoll is NOT:
- A video editor or post-production tool
- A cloud storage or backup service for your recordings
- A substitute for professional cinematography equipment in critical commercial work
- A free service — see "In-app purchases" below
Eligibility
To use RatioRoll, you must:
- Be at least 13 years old (or the minimum age in your jurisdiction)
- Have a compatible iPhone running iOS 17 or later
- Comply with the Apple App Store Terms of Service
The licence we grant you
By downloading RatioRoll, you receive a non-exclusive, non-transferable licence to use the app on your Apple ID's authorised devices, as described in the Apple Licensed Application EULA.
The licence is granted to you, not sold. We retain all intellectual property rights in the app itself, including its code, design, and brand assets. You retain full ownership of every video and audio recording you create with the app.
In-app purchases
RatioRoll is free to download. You can record up to 2 videos as a one-time trial on each device. To continue recording beyond the trial, you can purchase RatioRoll Pro, a one-time non-consumable in-app purchase that unlocks unlimited recordings on your Apple ID.
Trial behaviour
- The 2-recording free trial is one-time per device.
- Uninstalling and reinstalling the app does not reset the trial counter — we persist it in the iOS Keychain to prevent trial loops.
- The trial limit is disclosed in the onboarding screen and on the paywall before you record.
Purchase and refunds
- Purchase, billing, and refunds are handled by Apple under the Apple Licensed Application EULA.
- For refund requests, follow Apple's refund process. We cannot issue refunds directly.
- "RatioRoll Pro" is a one-time purchase tied to your Apple ID. Use "Restore Purchases" on the paywall to re-activate the entitlement on additional devices signed into the same Apple ID.
Acceptable use
You agree not to use RatioRoll to:
- Record people without their consent where consent is required by law in your jurisdiction
- Record in locations where filming is prohibited (private property, courtrooms, etc.)
- Reverse engineer, decompile, or attempt to extract the source code of the app
- Circumvent the in-app purchase paywall through any means
Your content
Every video and audio recording you create with RatioRoll is yours. We claim no ownership over your content. Your recordings are stored on your device in the iOS Photos library and never transmitted to us.
Disclaimers
RatioRoll is provided "as is" without warranties of any kind, to the maximum extent permitted by law. We do not warrant that the app will be uninterrupted, error-free, or compatible with every iPhone model or iOS version.
Some iPhone hardware features (such as Apple Log capture or full dual-lens MultiCam) require specific iPhone models — see the FAQ for the supported-device matrix. Where your iPhone does not support a feature, the app falls back gracefully but the unsupported feature will be unavailable.
Limitation of liability
To the maximum extent permitted by law, H3llo H3llo Ltd will not be liable for any indirect, incidental, consequential, or special damages arising from your use of RatioRoll, including loss of recordings, missed shots, or business interruption.
Where liability cannot be excluded, our total liability is limited to the amount you paid for the in-app purchase in the 12 months preceding the event.
Termination
You can stop using RatioRoll at any time by deleting the app from your iPhone. We reserve the right to terminate access if these Terms are breached, though for an offline app this is rarely practical.
Changes to these terms
We may update these Terms from time to time. Material changes will be reflected by updating the "Last updated" date above and, where appropriate, in the next app update.
Governing law
These Terms are governed by the laws of England and Wales. Any disputes will be subject to the exclusive jurisdiction of the courts of England and Wales.
