I just shipped PulseDaily — a mobile‑first habit tracker that runs entirely in your browser. No signup, no login. Your data stays on your device (localStorage by default). Live site: PulseDaily habit tracker Why I built it I’ve tried a lot of habit trackers, and I kept running into the same friction: You’re forced to create an account before you can even try it Too many features up front = decision fatigue “Gentle reminders” exist, but the setup is often more work than the habit itself PulseDaily is my attempt at a tiny, fast, low‑commitment alternative: open it, add a habit, and get through Day 1. What PulseDaily does 1) Habit management (add/edit/delete) Create habits quickly, keep names short, and adjust anytime. It’s designed for one‑hand mobile use. 2) 3‑state daily check‑ins + a Momentum bar Each habit has three daily states: 0 — not started 1 — partially done 2 — fully done The Momentum bar counts only fully done habits. The idea is to avoid “gaming the progress bar” and instead keep the signal honest. 3) Reminders: custom interval + custom message You can create up to 20 fixed‑interval reminders: Enable/disable toggle Edit / delete Test now (sends one notification + sound, without changing your schedule) Notifications use the browser Notification API Optional beep sound via WebAudio Note: This intentionally does not try to keep reminding you after the page is closed. It’s meant to be lightweight. 4) Shareable template landing pages (one‑click import) For cold start, I added a few template pages (Study / Fitness / Focus). Instead of sharing a generic homepage link, you can share a specific “starter set” like: Study habit tracker template Users can click Use this template and PulseDaily will write those habits into localStorage and redirect to /. Tech stack (quick overview) Framework: Next.js (App Router) Styling: TailwindCSS Storage: localStorage (local‑first) Notifications: Browser Notification API Sound: WebAudio (short beep) Analytics: Google Analytics (early funnel visibility) Why localStorage? I wanted “try it instantly” to be the default. For many people, a small habit tracker doesn’t need accounts or sync — it needs low friction. If usage proves it’s worth it, optional sync can come later. Cold start: what I did to make links work better Early on, the biggest challenge is not building features — it’s getting people to click and understand the product quickly. So I focused on three basics: 1. OpenGraph/Twitter cards so shares look credible and clickable 2. robots.txt + sitemap so search engines can discover pages faster 3. Template landing pages so a link can match a person’s intent (study vs fitness vs focus) These are small changes, but they can make a big difference when you’re starting from zero. Run locally bash npm install npm run dev Then open What’s next (roadmap) If people find it useful, the next things I’ll prioritize: A simple Share button on template pages (copy link + suggested text) Clearer onboarding so first‑time users can succeed in 10 seconds Better analytics events (e.g. templateapply, enablereminder, exportdata) Optional: import flow to match export/backup Feedback wanted If you try it, I’d love to hear: Is the first‑time experience obvious? Do reminders feel helpful or annoying? Which templates would you want next? (ADHD, writing, meditation, gym, etc.) Link: PulseDaily (habit tracker) Thanks for reading!
