I just keep switching calendars, I can't stay consistent with anything.
commentI just keep switching calendars, I can't stay consistent with anything. Here is what I've been using: 1. Finch, it's very cute and it feels rewarding when you complete tasks. You can also invite your friends and do tasks together, if that helps 2. Small, cute yearly calendars. If it's visually appealing to me, I can use it for longer. I tend to use these for a few weeks / months 3. Small white board, it's from Monday to Sunday 4. The google calendar for important events and appointments 5. Notebook to write what I'm currently doing and feeling, this helps me when I'm procrastinating too much because I'm not planning my day, I'm just writing what I'm doing right now and I often want to do something more productive 6. Notion, I made my own cute page with to-do's, daily activities depending on mood and energy etc. 7. I wrote down all the tasks I would like to complete in a week and very importantly, write how long they take (you can time yourself), this helps with the time blindness. Then I wrote my daily tasks on a small cute card, I devided the day into morning, afternoon, and evening. I wrote down my must do tasks, which I made sure to keep realistic, don't write too much. Then I also wrote additional tasks, if I feel like it. The idea is that you have to complete all must do tasks, you are allowed to skip one task every second day, and you must do one additional task. After doing this successfully for 4 days, I would reward myself with a piece of cake, small object or whatever you find joy in. Maybe this helps you somehow or maybe you get an idea ^ ^
Who feels this pain?
TARGET USERS
Adults with ADHD trying to manage personal life and schedules who experience chronic inconsistency and system fatigue.
Context
Current Workarounds
Where's the gap?
EXISTING SOLUTION GAPS
OPPORTUNITY & VALUE
Repeated complaints regarding the inability to maintain consistency with any single calendar or planning system over time.
Purpose-built to eliminate the guilt and friction of system-switching by automatically accommodating missed days and inconsistent planning habits.
A cross-compatible, low-friction digital planner featuring automated visual aids, color coding, weekly-monthly views, and frictionless recurring events tailored to accommodate attention shifts without penalizing inconsistency.
How does it make money?
MONETIZATION
Model
Users already spend significant amounts buying multiple physical planners and apps; a modest subscription that actually sticks offers clear high ROI in reduced stress and lost time.
How do you ship it?

RISKS & ASSUMPTIONS
Top Risks
Users with ADHD often abandon new digital habits quickly if initial onboarding requires too much configuration.
Users specifically requested a free digital app, making conversion to paid tiers challenging.
Adding requested features like color coding and multiple views risks cluttering the interface and overwhelming users.

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 3 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 "accessibility", "adhd", "browser-extension", 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 "ADHDCal: Low-Friction Adaptive Planner for ADHD Users" 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 accessibility?
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.
