Only iOS at this time.

For coaches recording videos, the app is free, so coaches can use the app easily on any personal device. The iPad display version of the app requires a yearly subscription to receive videos. Refer to the App Store for exact pricing.

Yes. For the athlete's iPad receiving the videos, the subscription offers a free trial period.

No. The app is sending and receiving compressed short video clips, but paying attention to your data plan is important if using the app with a cellular network connection. In the app settings of the camera version, you can adjust the quality of the transferred videos and see an estimate of the file size.

No. There is only one app. When the app is loaded on an iPhone or iPod Touch, it will load the camera version which uses the device's camera. When the app is loaded on an iPad, it will load the display version of the app that will receive the videos. Note that on an iPad, the user can switch the app to the camera version by clicking the icon in the lower right of the screen. This allows videos to be transferred from an iPad recording the videos to an iPad receiving and displaying the videos.

In the camera version, go to the app settings and enter a "Club" and "Coach" field of your choice to create a unique identifier. An example would be "Minneapolis Ski Club" for "Club" and "Kevin" for "Coach". Make sure these are unique names that no one else would use. Now enter the same "Club" and "Coach" in the iPad display version of the app. These IDs are case sensitive and must match exactly. Once the identifiers are setup, a video will transfer properly between the devices if connected to a reliable network.

Yes. Choosing the same identifier by multiple coaches will push their videos to the iPad with the same ID. For example, if two coaches are recording videos with the identifier "SSWSC 70 meter", the iPad with the same identifier will receive videos from both coaches.

No. Devices must be connected to a network, but it can be independent of the other and can be a mobile or WiFi network. Devices can be on the other side of the world. Distance doesn't matter.

No. The devices just need to be connected to the internet.

For coaches, VidJump has the 8 most recent videos taken accessible for quick review within the app. The videos recorded are duplicated to the Photos app in their original format for later video review and/or file management. The transferred video is a compressed copy that you can adjust the quality of. Once the video file is transferred to the athlete's iPad, a copy is also saved to the Photos app on the iPad. The app itself is a temporary place to view the 8 most recent videos quickly, but the copies saved in the Photos app are managed by the user. The app has a setting that will show a reminder and allow the user to delete videos saved to the Photos app after they are X days old.

Yes, but it is important to know that iOS devices have a temperature sensor that will shut the device down if it gets too cold. The user will have to take precautions to keep the devices warm enough to prevent shut down.

Any iOS device. iPhones or iPod touches are preferable, but the iPad app can be used as the camera by clicking the display-to-camera icon in the lower right of the iPad app.

At this time, the app performance and server storage performs best with short videos. This may be increased in the future, but this requirement allows the app to transfer videos quickly, even on slower networks.

In the app settings, the user can choose several resolutions and frame rates of the recorded video. These options are pulled from the device camera capabilities, and currently may go up to 1080p video at 60 frames-per-second. The user can also change the transferred video quality and the video will get compressed before transferring, keeping the original video frame rate. Changing the video transfer quality may be necessary depending on network speed conditions.

Video copies are saved to the Photos app, but the 8 most recent videos taken can be quickly reviewed within the app by clicking the portrait button in the lower right hand side of the screen.

It is recommended to wait at least until the current video is done compressing before closing the app or locking your screen. To guarantee successful transfer, the safest option is to not close the app until the current video shows "upload successful".

Before and after transferring, the videos are stored on each device. During transfer, they are stored temporarily on a public server and therefore are not secure. After the video is transferred, it is deleted from the public server after some time. If the video is not transferred immediately, it is purged at a later date.

Only an iPad at this time.

Yes, using an HDMI cable adapter or Apple TV, you can connect the athlete iPad to a larger TV or monitor. The app will recognize this and reconfigure the video grid to a grid of four videos that automatically scrolls as new videos are received, so there is no interaction needed with the device once it is setup properly.

Currently eight videos are shown at one time. This may be increased in the future, but at this time eight videos is optimal for device performance. Remember that a copy of each received video is saved in the Photos app, so an athlete can look there for older videos.

Yes. When a grid video is touched, it will enlarge to full screen with a scrubber for frame-by-frame analysis. There is also a slider on the right side that will change the video slo-mo rate to the desired value.

Not through the app itself, but it is possible to do this with Google Drive and some other providers. For example, install the Google Drive app on your iPad and change the settings so it does an automatic backup of your photos. Since VidJump saves a copy of the videos transferred to the Photos app, these should get uploaded to your personal cloud during the automatic backup. If Google Drive is shared with the athletes, they can access these videos once uploaded to the cloud.
