Lifetime doomscroll estimate
Enter your daily screen time and age to see an estimate of how many waking years your phone may take over the rest of your life.
Habit Doom
Habit Doom is an iPhone app and companion doomscroll calculator that estimates how many years of waking life daily screen time may cost. It also lets users compare their current usage with a lower target and links that estimate to habit-based app blocking.
Overview
Habit Doom is an anti-doomscroll iPhone app, and this page adds a companion calculator that turns daily screen time into an estimate of how many years of waking life your phone may take. The calculator asks for your current screen time and age, then shows the result alongside examples of what that time could otherwise become.
The broader product is built around habit-based app access: you choose distracting apps, complete daily habits, and earn screen time back. The pricing page describes a free iOS download with Pro upgrades for heavier habit tracking and more advanced blocking features.
What it does
What-if reduction view
Move a target-screen-time slider to compare your current usage with a reduced daily target and see what you could reclaim.
Activity translation
Shows a written breakdown of what the time represents, including example activities at lifetime, yearly, and monthly scales.
Result sharing
Provides a copy/share flow with text, image, and X sharing options so the result can be saved or sent to someone else.
Source-backed math notes
Includes a methodology section that distinguishes between cited research and reasoned estimates, with assumptions explained on the page.
Linked habit-locking workflow
Connects the calculator to Habit Doom’s habit-based app locking workflow, where habits are completed to earn app access.
Common ways to use it
Check personal screen-time cost
A person can enter their own screen time and age to get a concrete estimate before deciding whether they want to change their habits.
Test a lower usage goal
Someone trying to reduce usage can move the target slider and compare the reclaimable time at a lower daily screen-time goal.
Share a wake-up call
A user can share the result with a friend or family member as a simple way to explain why they want to cut back.
Preview the app approach
A reader considering the app can use the calculator as an entry point into Habit Doom’s habit-based locking workflow.
Reflect on current habits
An existing user can use the calculator’s numbers and methodology page as context for reviewing whether their current routine still feels acceptable.
Pros and Cons
Pros
- Transforms abstract screen time into a concrete lifetime estimate that is easy to understand.
- Provides a reduced-target view so users can compare current habits with a lower daily screen-time goal.
- Explains its methodology and separates cited research from reasoned estimates.
- Includes sharing and saving options for the result.
- Connects directly to a habit-based system for reducing app use, rather than stopping at measurement.
Cons
- The calculator depends on simplified assumptions, including a rounded life-expectancy baseline and estimates for many activity costs.
- The detailed habit-locking workflow is in the app, not on the calculator page itself, so readers need to move from the calculator to the product.
- Some advanced app features are only available in Pro, according to the pricing page.
FAQ
What does the doomscroll calculator do?
The calculator is a web page that asks for your daily screen time and age, then estimates how many years of waking life your phone may take if the pattern stays the same. It also lets you lower the target screen time to see what you could reclaim.
Is this connected to the Habit Doom app?
Yes. The source shows an iOS app that locks distracting apps until you complete your daily habits. The calculator page itself is separate, but it points to the same Habit Doom product.
How is the estimate calculated?
The page explains that the calculator is based on cited research where possible, plus reasoned estimates where evidence is thinner. It uses a simple assumption that your current screen time continues unchanged.
Is Habit Doom free?
The source mentions the app is free to download on iOS and also shows free and paid options on the pricing page, including monthly, yearly, and lifetime Pro plans.
Does it drain battery or require special setup?
The FAQ text on the pricing page says Habit Doom uses Apple's native Screen Time API and does not run background processes, which it says means no battery impact. The calculator page does not add more technical detail.
