Day Left

Day Left is a life countdown and digital detox app designed to make time feel real again. Most people do not lose their day in one big decision. They lose it in small moments: a few minutes of scrolling after waking up, a short video during work, another social media check before sleep. Day Left helps you see those moments clearly. Use Day Left to estimate how much time you have left, reflect on your screen time habits, and take back small blocks of your day through simple digital detox sessions. Key features: • Life countdown: see your estimated days, weeks, and years remaining. • Life progress: visualize how much of your life has already passed. • Screen time reflection: understand how phone usage and social media habits affect your day. • Digital detox sessions: take back 15, 20, or 30 minutes without mindless scrolling. • Daily progress: see how much time you still need to reclaim today. • Widgets: keep your life countdown and daily reminder visible without opening the app. • Habit projection: compare your current routine with a better version of your day. Day Left is not built to scare you. It is built to remind you that your time is limited, your attention is valuable, and each day can be used better. If you feel that social media, endless scrolling, or phone addiction is taking too much of your life, Day Left gives you a simple place to start. Reduce screen time. Stop wasting your days. Make every day count.

Verdict
The clearest difference is in-app purchases: Day Left at none against VERT's 1. Day Left also leads on iOS requirement (15.1 vs 17.0). VERT's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
