StayGray automatically switches your iPhone to grayscale, so apps feel less magnetic and you scroll less. Your screen stays black and white by default, and you decide when color is allowed. WHY GRAYSCALE Colorful interfaces are built to grab your attention. Take the color away and the little “reward hit” gets weaker, which makes it easier to stop the endless checking without blocking any apps. CONTROL WHEN COLOR IS ALLOWED • Schedules: set work hours, evenings, or bedtime for monochrome • App exceptions: keep Maps, Camera, Photos, or any app in color • Locations: turn color on automatically at home, at work, or at the gym • Color breaks: switch to full color for a bit, then go back to gray automatically TRACK YOUR PROGRESS See how your habits change over time and estimate how much screen time you save by staying in black and white. PRIVACY FIRST No accounts. No ads. No tracking. StayGray does not collect, store, or transmit personal data.

When the Same Thought Keeps Circling Not a crisis. Not a problem that needs solving. Just the same thought, going around once more, still hovering there. THEGREY exists for this state. When a thought keeps circling with no way out — and you don't need a way out yet. Not meditation. Not therapy. Not a mood tracker. No questions about how you feel. No suggestions. No record. 【 Why do you need THEGREY? 】Not a feature list. The reality you're living right now: • The same thought won't stop before sleep: your body is exhausted but your brain refuses to land, the thought grinding in the dark on repeat. • Walking into a place brings something back: the space itself is the trigger, old memories spiraling again without warning. • A date or anniversary arrives and the thought returns: time's inertia brings regret back automatically, no reason needed. • Shallow breathing, physical tension, thought follows: physiological anxiety feeds mental drain, the thought accelerating with your heartbeat. 【 Three entry points, three sources of circling 】 • THIS DAY | Time-triggered: circular thoughts triggered by time or date. Time seems to stand still. • THE SPACE | Space-triggered: circular thoughts triggered by location or setting. This space won't let the feeling go. • THE BREATH | Rhythm-triggered: circular thoughts triggered by rhythm or stress. The circling that happens between breaths. 【 Seven content invariants, strictly observed 】No second person · No action directive · No future tense · No causal framing · No self-comfort · No shareability design · No implied next step. No journal. No history. No progress report. Enter. Stay. Leave. Built on THE GAP Framework. Compliant with GAP-NLP-1.0.

Verdict
The clearest difference is update cadence: TheGrey.app at every 3 days against StayGray's fortnightly. TheGrey.app also leads on iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
