As answered by people managing DevFinanceTools and ADHD Notes.
ADHD Notes's answer:
Most task apps store what you type and then wait silently for you to remember to check them. ADHD Notes is built to reach back out. You capture a task or follow-up in one tap, attach the context future-you will need (the customer, the people, meetings, notes, and history), and set it to resurface on the right day. The app brings the thread back to you instead of relying on memory. It is also flat by design, with no folders or projects to build and abandon, so it keeps working on the busy days when other systems fall apart.
ADHD Notes's answer:
Next.js, React, and TypeScript on the front end, with Tailwind for styling. Supabase (Postgres and Auth) for the database and authentication. Hosted on Netlify with serverless functions for the backend. The iOS app is built with Capacitor. AI features run through a hosted large language model tier.
ADHD Notes's answer:
Most tools make you organize before you are allowed to use them, which is the exact friction that makes people with ADHD give up. ADHD Notes flips that: capture first, add context only if and when you want it, and let the app do the remembering. Compared to heavier tools like Asana, Linear, or ClickUp, it gives you rich per-task context without the team-collaboration weight. Compared to simple to-do apps, it adds the thing they miss: resurfacing, so follow-ups come back to you at the right time. It is the rare app that holds up on the bad days, which is the only kind that sticks.
ADHD Notes's answer:
People who juggle many active threads and cannot rely on memory to hold them. That includes adults with ADHD or ADHD-adjacent cognitive styles, and customer-facing professionals in support, customer success, account management, and sales, where a dropped follow-up is a relationship cost rather than just a missed task. Also founders, PMs, and anyone running many parallel conversations with customers, teammates, and vendors.
ADHD Notes's answer:
ADHD Notes grew out of a repeated frustration: the task is rarely the hard part, but remembering the loose thread weeks later is. Existing tools either demanded too much setup or just sat there waiting to be checked. ADHD Notes was built to externalize memory instead: capture fast, keep full context, and have the app surface what needs you next. It started as a personal tool refined over many iterations, and became a single-user productivity app for people who want to stop holding everything in their head.
