Positivity Lite is your personal journal for the good things in life. We tend to notice the negative more than the positive. Positivity Lite helps you rebalance that – by consciously capturing what enriches your day. WHAT TO EXPECT CAPTURE MOMENTS Photograph or describe moments that matter to you. Mark them as significant or as insights – and look back on them whenever you need a boost. TIP OF THE DAY A fresh daily impulse to get you thinking and taking action. YOUR STATISTICS See at a glance how many positive moments you've collected this week, this month, and this year. YOUR DATA STAYS WITH YOU Positivity Lite stores everything locally on your device. Nothing is sent to the cloud, no account required. Sharing is optional – and always on your terms. Positivity Lite is intentionally simple – no subscription, no distractions. Just you and your moments.
