iOS (Apple)
Typically we would recommend the latest Apple Devices. Apple iOS is as straightforward to use, as it is powerful. As a team, we prefer the performance of the app on this platform based on our own experiences.

Android
There is a considerably larger variety of Android devices on the market that would be suitable enough for basic use of the App (shorter, less detailed reports with less than 100 photos). For more demanding use of the app (large detailed reports with hundreds or even thousands of photos, audio and/or video) we recommend newer, more expensive devices.
Unlike Apple, Android devices rely more on the device specs to offer good performance. We recommend devices with at least 2GB of ram and 2ghz processor. This information can be found in your settings, under about this device.

Conclusion
As there are so many devices using Android we can't comment on every one, however any device with at least 2GB ram and an 8MP camera should provide reasonable performance and quality.
