Sentiv is a GPS fitness tracking app with a twist. Use the GPS tracker to track your running, biking, hiking and walking activity or sync to a step tracker to track your steps. That activity or steps then counts towards winning money for beating your friends – or raising money for a charitable cause of your choice. Track your runs, bikes, hikes, walks. Sentiv displays your speed, duration, miles/km, average pace, elevation change. That activity counts towards all your GroupFit and CauseFit challenges. Pick a charity and invite crowdfunding backers to collectively raise money for charity based on the miles you log.
