How to Use the Digital Detox Effect Predictor
Few people ever check exactly how many hours a day they spend on their phone. When they finally look at the screen-time stats, the number is usually higher than expected. This calculator takes your average daily phone use, how many days you plan to detox, and how much you want to cut back, then estimates how much time you'll actually get back.
We multiply your daily use by your reduction goal to get your average daily time gained, then multiply that by the number of detox days to get the total. For example, someone using their phone 4 hours a day who cuts back 50% for two weeks would gain about 14 hours over that period — roughly enough to finish a couple of 200-page books, which the calculator also estimates for you.
Rather than attempting a full 100% detox right away, starting around 30-50% and building up from there tends to stick better as a habit. Assigning the recovered time to specific activities — reading, exercise, a walk — makes it far more likely you'll follow through instead of quietly sliding back into old habits.
