You can try SPOTTR for Android devices here. (iOS version will be ready later this fall) The app is completely free! I planned to add monetization but removed it after initial feedback. I realized that I should give to the community a working product first, and build it up based on what you request. Please help me improve the app by answering these questions: - What do you think about the app in its current state? - How do you usually track your score? Do you use some other ballistic app? - Is there any specific feature you’d want to see next?
