Zeno is a behavioral wellness app that combines real-time screen monitoring, intentional friction design, and on-device privacy protection - with zero data ever leaving your phone.
A look at the key screens — all running locally on your device, no account needed.
Android 8.0+ · Free · No account required
Twenty-five purposeful modules that work together to change your relationship with your phone - without requiring willpower alone.
A 0–100 behavioral score calculated from four signals: total screen time, scroll depth, session fragmentation, and peak-hour usage. Watch it improve week over week.
Before opening Instagram, TikTok, YouTube, or any app you choose - Zeno shows a brief pause screen. Not a hard block. A moment long enough for your conscious mind to decide.
One tap activates Study Mode: social media blocked, study timer running, zero distractions. Built for board exams, entrance tests, and any session that demands deep concentration.
90-minute deep work blocks for office and remote professionals. Enable it before meetings, code reviews, or presentations - Zeno keeps distractions out of the way.
Put the phone away during dinner, bedtime, or any moment that matters. Weekly Report Cards give parents a clear picture of usage trends in plain numbers, no jargon.
Your 7-day usage chart, time saved, clean days, and top insight - all in one screen. Plain language, no jargon. The coach reviews weekly patterns and tells you exactly where to focus.
Ten milestone achievements track real progress: first clean day, 3-day streak, 7-day streak, score under 30, 100 friction moments, and more. Every badge is earned through measurable change.
After 18 minutes of uninterrupted scrolling, Zeno surfaces a gentle break prompt. The app does not punish you - it reminds you. You always have the choice to continue.
A local VPN blocks 50,000+ tracking domains at the DNS layer. A Privacy Noise Engine sends randomized background queries to dilute ad network profiles. Zero telemetry.
Personalized daily briefings built from your real usage data. Charts, peak-risk hour identification, and coaching insights - computed entirely on your device. No cloud, no account.
Set a hard daily cap on any app - 30 minutes on Instagram, 20 on TikTok. When the limit is reached, the app is blocked for the rest of the day. No bypass. No negotiation. You set the rule when you're thinking clearly.
Schedule a nightly cut-off - say 10:30 PM - and Zeno automatically blocks social media, news, and any app you choose. Protect your sleep window without relying on willpower at the end of a long day.
When you open a guarded app, Zeno activates grayscale on the screen. Color is the single most powerful dopamine trigger in app design. Removing it makes the feed noticeably less compelling - backed by behavioral science.
7-day, 14-day, and 30-day guided programs with daily goals that decrease week over week. Each day has a single measurable target - a specific score ceiling, a clean-day requirement, or a friction count. Progress tracked locally, no sign-up needed.
Place your live addiction score directly on your home screen. Every time you pick up your phone, you see your number - not a notification badge. Awareness alone changes behavior. The score updates throughout the day without opening the app.
After every friction delay, Zeno asks: "Why did you open this?" Tap Bored, Anxious, Procrastinating, or Planned. Over time, your trigger patterns reveal the emotional root of your scroll habit - giving you something to actually change.
Allow Instagram only between 7–8 PM. Allow Reddit only on weekends. Set a precise time window per app - outside that window, the app is blocked automatically. No willpower required at the moment of temptation.
Enroll any app - Instagram, TikTok, Reddit - and Zeno intercepts its notifications silently. Once an hour, it delivers a single grouped summary instead of a stream of interruptions. Your focus stays unbroken; you stay informed.
A color-coded heatmap of the past 90 days shows exactly when your usage was under control (green), borderline (amber), or excessive (red). Your current streak and longest streak surface at the top - clear proof that your habit is changing.
Create named recurring blocks - "Morning Focus 6–8 AM weekdays," "No-phone dinner 7–8 PM every day." Each zone locks guarded apps on schedule. Active zones glow green in the dashboard - no manual activation ever needed.
Generate a shareable stats card showing your addiction score, weekly screen time, daily average, and friction count - styled as a polished graphic, saved directly to your gallery. Share your progress with accountability partners or just keep it as a milestone record.
When you hit 75% of your daily limit for any app, Zeno sends a heads-up notification: "18 of your 30-minute Instagram limit used." You get a warning with time to course-correct - before the hard block kicks in, not after.
For apps with a 60-second or longer delay, Zeno guides you through 4 deep breath cycles before showing the countdown. Research shows slow breathing activates the prefrontal cortex - the part of the brain that makes deliberate decisions rather than impulsive ones.
Enable a persistent notification that shows your current addiction score in the status bar all day. Green when you're in control, amber when drifting, red when you've overshot. A constant ambient reminder - without opening the app at all.
Whether you are studying for boards, leading a meeting, raising a family, or teaching a class - Zeno has a mode designed for your context.
One tap activates Study Mode. Social media blocked, timer running, streak tracked. Built for JEE, NEET, board exams, and any session requiring sustained concentration.
90-minute Deep Work blocks keep social interruptions out during the hours that matter most - writing, coding, strategy, or any task requiring sustained cognitive effort.
Family Time mode puts the phone away during dinner, bedtime, or any moment that matters. Weekly Report Cards show usage trends in plain numbers - easy to share and discuss with children.
Activate a Focus Block for school hours and block all non-educational apps instantly. Use Zeno yourself to demonstrate responsible technology use - students respond to what they see modeled.
No accounts, no cloud sync, no analytics SDKs. Zeno is the rare wellness app that actually practices what it preaches.
Zero personal data collected. We don't collect, store, or transmit behavioral data. All usage stats, scores, and settings stay in a local encrypted database on your device.
100% on-device processing. The behavior coach, VPN blocker, and noise engine run entirely on your phone. No server, no sync, no cloud dependency.
No account required. No email, no sign-up, no login. Opens and works immediately.
Open permissions. Every sensitive permission is explained in plain English before you grant it. Nothing hidden.
Local VPN only. The DNS blocker creates a local TUN interface - traffic never leaves your device. No external VPN server involved.
Auto-deleted after 90 days. Usage records are pruned automatically. No indefinite data retention.
No configuration required. Enable the features you want and Zeno runs silently in the background.
The onboarding explains exactly what each permission does. Usage Access shows your real screen time. Accessibility adds friction delays. You control everything - enable only what you want.
Choose which apps trigger a delay before opening. Set a 5–30 second pause, or activate scroll-break detection after 18 minutes of continuous scrolling. You can always override.
Pick Study Mode for exam prep, Deep Work Mode for professional focus, or Family Time Mode for screen-free moments. Each mode configures itself in one tap.
Every week your Report Card shows your 7-day usage chart, clean days, time saved, and a top insight written in plain English. Build streaks, earn achievements, and watch your addiction score fall.
We use only the permissions we absolutely need. Here is what each one does and why we need it.
Reads per-app screen time to calculate your addiction score and usage charts. Processed entirely on-device, never transmitted.
Detects when a guarded app opens so the friction overlay appears, and detects scroll events for the scroll-break feature. No text, passwords, or sensitive content is ever read.
Creates a local TUN interface for the DNS tracking blocker. Zero data is routed through any external server - it is a 100% on-device proxy.
Shows the friction delay countdown on top of your chosen apps. Required for the overlay to be visible.
Lets the Privacy Shield scan installed apps. Results stay on your device and are never transmitted.
Restores your configured privacy shields after a device restart without requiring manual re-activation.
Free to download. No account. No data sold. Just control.
