Running FieldClock is like any other equipment on your farm: your experience will be much better if you buy the right hardware. While FieldClock will work on many older devices you will not get the same lifespan from the devices and may not be able to get the latest features as they come out.
It is also important to keep in mind that the size of your organization will directly impact how FieldClock works. Larger organizations require more data and will see greater benefit from better hardware.
In general, we always recommend buying the best devices that meet your budget.
FieldClock is compatible with any iOS device running iOS 10 or newer. Even though some older devices will run iOS 10, we really don't recommend running anything older than an iPhone 7. The processing speed and camera quality on the newer phones will provide a much smoother syncing and scanning experience.
Our current recommended iPhone is the iPhone SE. This model is Apple's least expensive phone and the internal specs are as powerful as an iPhone 11 Pro. When it comes to "bang for the buck", this phone can't be beat.
Android is a little trickier due to the variety of devices available. FieldClock is compatible with 15k+ models of Android devices. At a minimum, you're going to want a device with at least 4GB of RAM and a multi-core processor.
Our current recommended Android device is the Samsung Galaxy A51. It's a good all-around phone at a reasonable price-point.
