We live in a distracted, busy world that masks our true selves and hides our emotional triggers from us. A solution rooted in data science is finally here. force4change reveals the impact of people, activities, places and events on you and your emotions. The app’s data driven approach, life analytics and the machine learning powering it, mean that it can help you out in a pinch, when you need a quick way to get back into a good headspace. Quantifying your emotions and the causal factors behind them also makes it a great tool for longer term self improvement. Central to our app and approach are what we call “mindtags” - basically short captures of your emotions and their underlying causes throughout the day. Adding a mindtag takes less than a minute and logging an entry with multiple mindtags takes 1-3 minutes. Mindtagging allows us to gain a full picture of you that gets richer and more helpful over time. As you enter more mindtags and your reflection collection grows, details and patterns emerge that would otherwise get lost in the buzz of life. And while we’re all about inner peace, pretty pastel colors, and helping you be the best you, we firmly believe regular effort, actionable data and understanding emotional triggers are keys to progress. We go beyond simply tracking and documenting you. We give you access to inspiring content that will help you along the road. ––––––––––––––––––––––––––– Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period.
