Death Day Sim calculates your simulated death date based on real statistical data and gives you a live countdown clock ticking down to that moment — down to the exact year, month, day, hour, minute, and second. Answer a few questions about your age, lifestyle, and health, and the app generates a personalized death date using actuarial life expectancy data and risk factor adjustments for things like smoking, alcohol use, exercise, diet, sleep, stress, and existing medical conditions. Once your date is set, the clock runs continuously in the background, always reminding you how much time you have left. Features include a live countdown clock updated every second, a fully local profile with no account or sign-up required, lifestyle and health-based calculations, and the ability to reset and recalculate at any time. All data is stored locally on your device and is never shared or uploaded. For entertainment purposes only. This app does not provide medical advice and the simulated death date is not a prediction of any real event.

Verdict
The clearest difference is in-app purchases: Death Day Sim at none against Life Countdown's 1. Death Day Sim also leads on update cadence (daily vs every 4 weeks) and device support (3 vs 1). On price and ads there is nothing between them.
