Free productivity tools that run entirely in your browser. No accounts. No servers. No tracking. Your data stays on your device.
Each tool is a single file. Open it, use it, close it. That's it.
Browse ToolsSubscription tracker
Track every subscription and recurring payment in one place. See monthly and annual totals, get renewal countdown alerts, and export your data. Find hidden costs you forgot about.
Medication tracker
Track daily medications, mark doses as taken, and monitor adherence streaks. Includes inventory tracking with low-stock warnings and PDF adherence reports you can share with your doctor.
Daily habit tracker
Build better habits with streak tracking, completion heatmaps, and flexible scheduling. Supports daily, weekday, weekend, and custom day-of-week frequencies. See patterns at a glance.
Persistent reminders
A reminder app that actually nags you. Set a task and a deadline, pick an intensity level, and get persistent browser notifications until you're done. Auto-escalation mode increases urgency over time.
Expense splitter
Split expenses with friends, roommates, or travel groups. Create groups, add expenses with equal, custom, or percentage splits, and see the minimum payments to settle up. No Splitwise subscription needed.
Co-parenting coordination
Custody calendar, shared expense tracking, and activity log for co-parents. Four schedule patterns (alternating weeks, 2-2-3, 3-4-4-3, every other weekend) with per-day overrides. Running balance shows who owes whom.
Plant care tracker
Track watering schedules for all your plants. Set custom frequencies, log waterings with one tap, and see which plants are overdue at a glance. Sort by urgency, name, or location. No subscription traps like Planta.
Most productivity apps want your email, your credit card, and a monthly subscription. They need servers, databases, and analytics pipelines. They track what you do, when you do it, and how often you come back.
These tools don't do any of that. Each one is a single HTML file that runs in your browser. Your data lives in localStorage on your device. Nothing is sent anywhere. There are no accounts to create, no passwords to remember, no subscriptions to cancel.
That's boring. On purpose.
"Boring" means the tool does what it says and nothing else. No growth hacks, no engagement loops, no dark patterns. Just a thing that solves a problem and gets out of your way.
Each tool is one HTML file. No build step, no node_modules, no deploy pipeline. Right-click, save, open in a browser.
Everything stays in localStorage. No cloud sync, no analytics, no third-party tracking. Close the tab, your data is still there when you come back.
Desktop, tablet, phone. Any modern browser. Some tools support PWA install so you can add them to your home screen and use them offline.
Your data will be gone. Each tool has a JSON export/backup feature. Use it periodically if your data matters to you.
Yes. Open the tool in your phone's browser. HabitFlow, MediTrack Simple, SplitSimple, CoParent Simple, and PurePlant support "Add to Home Screen" for an app-like experience. All tools are responsive.
These tools are free. If premium features appear in the future (cloud sync, notifications, PDF reports), the core tools will stay free.
Absolutely. Each tool is a static file. Drop it on any web server, CDN, or just open it from your filesystem. No server-side requirements.
Export your data as JSON from one device, import it on the other. Manual, but deliberate. No cloud sync means no cloud risk.
