FLOW STATE ISN'T LUCK. IT'S ONE TAP AWAY. Athletes enter the zone in seconds. So can you. Most focus apps give you 47 settings to choose from. That's the problem. Your ADHD brain can't decide - so you never start. Flow State has ONE button. That's it. Tap once -> 90 minutes of unstoppable focus → Done. No choices. No paralysis. Just peak performance. ----------------- WHY FLOW STATE WORKS -> ONE TAP to enter deep work (no decisions, no drop-off) -> 90-MINUTE sessions (science-backed, Huberman protocol) -> ZERO SETTINGS (built for ADHD brains that overthink) -> SOUNDSCAPES + BODY DOUBLING AUDIO (brown noise + ambient work sounds) -> 2 SESSIONS PER DAY MAX (scarcity = you protect what's rare) ----------------- YOU'RE NOT LAZY. YOU'RE JUST USING THE WRONG TOOLS. Traditional productivity apps are built for neurotypical brains. Endless options. Complex systems. Decision fatigue before you even start. Flow State is different. It's built for high-performers with ADHD who need to ELIMINATE friction, not add more. One tap. The timer starts. Your phone locks. The soundscape plays. You work. That's it. ----------------- WHAT USERS SAY "I've tried 10+ focus apps. This is the only one I actually USE." "Finally - an app that doesn't make me choose between 47 timer options." "90 minutes feels impossible until you do it once. Then you're hooked." ----------------- THE SCIENCE - 90 minutes = your brain's natural ultradian rhythm (neuroscience-backed) - Flow state requires 15-20 min to enter (that's why Pomodoro's 25 min doesn't work) - ADHD brains excel in flow - they just need the right environment Flow State creates that environment in one tap. ----------------- WHAT YOU GET - One-tap flow sessions (25, 50, or 90 minutes) - Soundscapes engineered for focus (brown noise, body doubling audio) - Session tracking ("17 elite sessions protected") - Zero distractions (phone dims, notifications silenced) - Micro-celebrations every 15 min (your ADHD brain needs wins) ----------------- WHO THIS IS FOR -> ADHD brains tired of apps with 47 settings -> Founders, creatives, students who procrastinate -> Anyone who's ever spent 3 hours "about to start" -> People who know they're capable of greatness—if they could just FOCUS ----------------- STOP RESEARCHING PRODUCTIVITY METHODS. START DOING THE WORK. Download Flow State. Tap once. Lock in for 90 minutes. That's how champions are built. ----------------- Disclaimers: This app is not intended to provide any medical guidance or advice.

zem is the to-do app for the days you can't. the hardest part of any task is starting. so every task in zem gets a 2-minute button — tap it and just begin. finishing is optional. that's the whole pitch. what's in the box: - a quiet today list, no streaks shouting at you - "split this task" — paste in the wall ("file taxes") and zem breaks it into the first three small steps you can actually start - a mascot that grows as you complete tasks (and forgives missed days) - a morning energy check-in that matches the day's tasks to where you're at - soft notifications, capped at three a day - iOS widget so today's next step is on your home screen - end-of-day swipe — see what you got done in 30 seconds things zem deliberately does NOT do: - shame you for missing a day - ship streak counters that reset on one bad week - ask for your contacts, calendar, or location - sell your data — we don't even collect task content privacy: - we never see what you write. tasks stay encrypted on your device and on our backend; we can't read them. - the only third party that ever touches a task title is openrouter (which forwards it to the underlying model), and only when you tap "split" (with caching so the same title never goes twice). - anonymous usage events are off by default in the EU. you choose. free 7-day trial, then a small monthly or yearly subscription. cancel any time from the App Store. — Subscription details (Zem Pro auto-renewing subscription): - Zem Pro Monthly — billed monthly at the price shown in-app, auto-renews each month until cancelled. - Zem Pro Yearly — billed yearly at the price shown in-app, auto-renews each year until cancelled. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions in your App Store account settings after purchase.

Verdict
The clearest difference is in-app purchases: FlowState at none against Zem's 2. Zem's advantage is iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
