We often gets asked what are the best beacons for iOS and/or Android. As mentioned in our post on Which Beacons Are The Most Compatible, all beacons, whether iBeacon or Eddystone, are compatible with iOS and Android.
The universal compatibility comes about because all beacons are slight derivations of a few standard circuit designs and firmware provided by Texas Instruments, Dialog and Nordic who produce the System On a Chip (SoC) inside beacons.
Instead, you should be looking at more physical aspects such as battery size, battery life, range, on-off buttons, waterproofing and included sensors.
