Both Apple iOS and Android are compatible.
We strive to keep the two versions the same. We add new features to each as we develop them, however, so sometimes one version will have a new feature first.
The Forward Chess app is designed for Android and iOS devices, not for desktops. That being said, we have heard that some people use Android emulators such as AMIDuOS, Andy, or Bluestacks to run Android apps on their desktops. This may be an option, but it is not something we have tested or recommend. If you do decide to download an Android emulator, be careful to avoid viruses.
No. We couldn’t allow Forward Chess to work on jailbroken iOS devices without violating our contractual obligations.
