Professional testcards to calibrate and test your Home Theater. HD & 4K compatible. In-app purchase after compatibility testing to allow sharing between iOS and Apple TV.

Professionals use test cards to calibrate broadcast systems and cinemas use them too, so why shouldn’t home cinemas or theatres use them too? TestCard ProHD is the innovative means to calibrating your screen to ensure a consistent and correct representation of display media. (In-App purchase required after ensuring this will work on your TV / Display.)

** In-App purchase required after compatibility testing for full functionality. See below for why. **

Additionally, TestCard ProHD also now includes an SPL or “decibel” meter to assist with setting up surround sound sources. It’s a solution for calibrating both audio and visual elements within the home that can also be used in professional environments.

Newest version now includes a Audio Visual Synchronisation test to help diagnose lip-sync issues.

TestCard ProHD is the application for setting up a modern High Definition TV or projector. We’ve grouped together some common types of test cards as well as some new ones that will help set up home theaters to a professional standard.

Adjusting the contrast and brightness is essential to ensuring that you get the best from your TV or projector, but color is vitally important too. Further, test cards for motion and sharpness tweak more performance from your screen. Using these test cards and their instructions you’ll be able to tweak to get the best you can without the expensive of a dedicated calibration service.

Only by applying test cards in a controlled manner will you to get the best from your home theater and TestCard ProHD is the right tool, taking advantage of the unique abilities of the iPhone and iPad.

Within modern screens there are many techniques used to smooth motion. These can also have a detrimental effect, yet correctly set some do improve the picture. Having a repeating pattern to assist the setting of motion controls is essential. TestCard ProHD has test cards specifically design for motion testing on a screen.

Further, each test card has an information section to give you concise information and instruction on how to use it. The more that can be gained form each test card, the more information is provided. For ease of use the instruction are displayed on the iPhone / iPad while simultaneously displaying the test card on the external display.

Access to the test cards on the external display, Virtual Blue Filter and the SPL meter are only available after an In-App purchase. Using the default test screen please ensure that you have tested your device with the media adaptor, or Apple TV, on the external display before purchasing access. This is to allow you to verify that your system is fully compatible before purchase, and to share a single purchase with your iOS devices and Apple TV.

TestCard ProHD can be used with Apple TV V2, V3, V4 or V5 / 4k, or with the Apple media interfaces for HDMI or VGA.

Apple TV V2 and V3 can be used as the external display interface using AirPlay Mirroring. Simply switch on AirPlay on the iPhone or iPad and select Mirroring. See below for instructions on AirPlay Mirroring.

For HDMI or VGA Apple produces two types of media interface. While we’ve included some test cards for VGA / computer calibration, the home cinema user who is looking for 1080p compatibility should opt for the HDMI based media interface.

Apple TV version of the app is also available. Once access to the testcards is bought on either iOS or Apple TV app, you can have access on the other type of device without additional purchase. The In-App-Purchase is shared between all compatible devices registered on your Apple ID.

Apple TV AirPlay Instructions:
To enable AirPlay Mirroring connect your iOS device and your Apple TV to the same Wi-Fi network. For iOS 7 swipe up from the bottom of your screen to access Control Center. Tap on the AirPlay icon, select your Apple TV and switch on Mirroring. More details can be found on Apple’s support page http://support.apple.com/kb/ht5209

What’s New

Version 1.74

Fixing bug that prevented transition from testcard list to the actual card. It has been traced to new code that was used to update from definitions that are being retired by Apple. Part of keeping the app fresh for new versions of iOS. We mishandled how the new types now need to be stored. Seemed to work on updated apps but not fresh installs.

A big thanks to the user who reported this as the app seemed to be working when on our phone and simulator.

Works great.

Used this on my TV and the picture is much better now. Colours and picture not glaring but more like a cinema. Haven’t used the audio tests as I don't have surround sound but nice to know I can use them later.

Rip off

Paid £4.99 for patterns and they don’t work I want my money back

Developer Response ,

Sorry you're having trouble with them and you can certainly get a refund via the App Store. The patterns do work but if you're having difficulties we're happy to offer some technical support for you. Just email us.

Dreadful - Don’t waste your money

Purchased for ATV and OLED TV - settings for brightness and contrast are way off - pure junk. The free stuff on YouTube gives better results.

Developer Response ,

With ATV please ensure that the video settings it automatically chooses is appropriate for the content that you wish to calibrate for. Override those settings when necessary so that you are calibrating correctly (we don't get access to this via programming frameworks, sorry that is out of our control). We've had other OLED users who have used the app very successfully to calibrate their screen, but we did add more guides on how to set up the OLED and when the OLED uses the full black range rather than the TV black range, which we provide testcards for. If you need help you can always email for technical support and I'll do my best to help. But please do ask Apple for a refund as a very small developer I would rather have you refunded than remain unhappy with your purchase.
