Simple and reliable timers to use with your XF or XF style workouts. 4Time contains a standard timer, countdown timer, interval timer, lap timer, and even a fully programmable tabata timer. ◦ 4Time is the only timer in the App Store that allows you to use your second iOS device as a remote control! (in-app purchase required; both devices must be running same version of iOS). ◦ All timers allow you to tap the screen to add reps (except the lap timer, which allows you to add laps), helping you or a friend to keep count while you're working out. ◦ After you complete your workout, you're automatically shown your results (if available) displaying your completed reps for each round. This makes it easy to track your workout round by round and record this data to your personal log/journal easily. ◦ Tabata Timer: Allows you to set work, rest between intervals, rest between tabatas, number of rounds, and number of tabatas -- as well as a custom name for each tabata. Everything you need! ◦ 4Time also give you access to your device's music library so you can listen to that power song to push you the extra mile! ◦ Like to be original? 4Time offers several different timer sounds for you to choose one (requires in app purchase). **************************************************** If you encounter any problems with 4Time please email us directly (supportdreamworkshop@me.com) as opposed to leaving a negative review.

B3 Runtime is an interactive, location-based quiz app where the users have to explore their surroundings while at the same time answer tricky questions. As the player moves throughout the checkpoints of a course, questions are prompted that the player then has to answer. By combining the best of two worlds: physical activities with intellectual stimulation, this app provides the users with an exciting experience! Continued use of GPS running in the background can dramatically decrease battery life.
