HardBlock: High-Friction Screen Time Enforcement for ADHD & Digital Addiction
Built-in digital wellbeing and screen time tools are too easy to override via frictionless bypass buttons, rendering them useless for users lacking the impulse control or executive function to respect their own boundaries.
Is the problem real?
Built-in digital wellbeing and screen time tools are too easy to override, failing users who lack the self-regulation or executive function to respect boundaries they set for themselves.

I always have to play 5D chess against my future self.
commentYup, I also can't enforce shit on myself because I know I can just turn it off. I always have to play 5D chess against my future self. Don't know if you're looking for suggestions or solutions, so I could also share some of my process. (Mostly things that didn't work lol)

The only solve for me was to just delete the app

Who feels this pain?
TARGET USERS
Individuals struggling with phone addiction and executive dysfunction who need an ironclad way to restrict app usage that they cannot easily override.
Context
Current Workarounds
Where's the gap?
EXISTING SOLUTION GAPS
OPPORTUNITY & VALUE
Users repeatedly note that built-in digital wellbeing tools fail completely because the user maintains authority to instantly disable them when impulse strikes.
Unlike native Apple Screen Time or Google Digital Wellbeing which offer an instant 'Ignore Limit' button, HardBlock eliminates the immediate bypass trigger, shifting the authority away from the user's impulsive moment.
A mobile and desktop app blocker that enforces un-bypassable restrictions through programmatic friction, such as requiring a trusted accountability partner's approval, a mandatory 24-hour delay on limit changes, or completion of complex, focus-intensive tasks to unlock apps.
How does it make money?
MONETIZATION
Model
Users are playing '5D chess' against themselves and resorting to extreme measures like network router modifications. They will pay a premium to protect their productivity and mental health if a tool truly solves their self-regulation gap.
How do you ship it?
MVP PLAN
“Outsmart your impulsive self with screen blocks you actually can't bypass.”
A mobile and desktop app blocker that enforces un-bypassable restrictions through programmatic friction, such as requiring a trusted accountability partner's approval, a mandatory 24-hour delay on limit changes, or completion of complex, focus-intensive tasks to unlock apps.
Core Features
Weekly Roadmap
- •Integrate iOS Screen Time API and Android Accessibility Services
- •Build a basic block schedule system for selected target apps
- •Implement a local 'Time-Locked Edit' feature that enforces a 12-hour delay before a rule can be modified
- •Create an invite-link flow to connect an Accountability Partner via simple web dashboard or app
- •Build a push-notification system requesting approval for limit changes from the partner
- •Implement MDM/Device Administrator constraints to prevent easy app uninstallation during blocks
- •Onboard 50 beta testers from r/nosurf and r/ADHD
- •Fix bugs related to background service termination by the mobile OS
- •Integrate basic Stripe/App Store subscription processing
- •Launch on Product Hunt and subreddits showing active video proof of an un-bypassable block
- •Publish a guide titled 'How to Outsmart Your Future Self' outlining the app's core psychology
- •Monitor initial conversions and retention metrics
Target niche communities dedicated to self-regulation, such as r/ADHD, r/nosurf, r/ someproductivity subreddits, and ADHD productivity creators on X.
RISKS & ASSUMPTIONS
Top Risks
Apple or Google might restrict deep system blocking mechanisms or reject apps that heavily restrict core user control options.
If users can simply delete the app to bypass the block, the entire value proposition collapses, requiring creative MDM or configuration profile workarounds.
Relying on a second person to set up or approve overrides introduces coordination friction that might stall initial onboarding.
Should you build it?
Run an Investment Memo to get a structured Go / No-Go verdict, competitor landscape, unit economics, and a 90-day validation roadmap for this opportunity.
Generate an investment memoWhat this score means
This opportunity scores well above the median for ideas surfaced by MonetScope, with a validation sub-score of 9/10 against 4 independently sourced evidence signals. A "strong" rating in this band typically means the pain signal is consistent and recurring across multiple discussions, but one of the three pillars (severity, willingness to pay, or competitor weakness) is somewhat softer than top-tier opportunities. Founders evaluating this should focus customer discovery on the softest pillar first — confirming the gap before committing engineering time to a build.
Why this matters for SaaS founders
It sits at the intersection of "adhd", "automation", "digital-wellbeing", which makes it relevant to a specific subset of founders rather than a generic horizontal opportunity. SaaS opportunities at this stage tend to win on the strength of their initial wedge — a single workflow that the target user runs every week, where the existing solution is either spreadsheets, a clunky incumbent feature, or a manual process they hate. The build cost is moderate; the distribution cost is everything. The MonetScope pipeline surfaces this category alongside other saas signals, which is why it appears here rather than in a generic "trending ideas" feed.
Scores are derived from real forum discussions across Reddit, Hacker News and X, weighted by evidence volume and signal quality. How scoring works
Frequently asked questions
Is "HardBlock: High-Friction Screen Time Enforcement for ADHD & Digital Addiction" a real validated startup idea or just an AI-generated suggestion?
MonetScope does not generate ideas from a language model's imagination. Every opportunity on this site is anchored to specific source posts and comments from real public discussions — typically on Reddit, Hacker News, or X — where actual users describe the pain in their own words. The AI's role is structuring, scoring, and grouping those signals into a navigable opportunity, not inventing the problem.
How recent is the underlying data for adhd?
MonetScope's spider pipeline runs continuously and surfaces opportunities as new evidence accumulates. The "Updated" date in the header reflects the most recent re-scoring of this specific opportunity. Most saas opportunities visible in the public catalog draw from discussions in the last 30-60 days; older signals are de-prioritized because user pain shifts faster than most founders assume.
What's the difference between "overall score" and "validation score"?
Overall score is a composite across six dimensions — pain, urgency, willingness to pay, market size, defensibility, and execution ease — designed to give a single number for triage. Validation score is narrower: it asks "how cleanly does the same signal repeat across independent sources?" An opportunity can score high on overall but lower on validation when one or two large discussions dominate the evidence; conversely, validation can be high on a smaller-overall idea where the signal is consistent but the addressable market is modest.
