Most apps that promise calm sell you a subscription, a streak and a daily push notification at 7:42 in the morning. Overstimulated does none of that. It opens. You use it. You close it. Nothing is counted.

Context

The wellness category on the App Store generated over $4 billion in consumer spend in 2024, with Calm and Headspace alone accounting for the majority. Both products are built on the streak-and-subscription model — daily push notifications, locked premium content, leaderboards in some flavours, retention metrics dressed up as personal growth. The user is the product; the metric is the goal.

Meanwhile the population they serve is changing. Adults with ADHD, autism, anxiety, PTSD and chronic-pain conditions have been increasingly visible since 2020, and the language of sensory overload, executive function and intrusive thoughts has moved from clinical literature into mainstream vocabulary. Apple itself reflected the shift — iOS Focus modes, Reduce Motion, Sensitive Content Warnings, Background Sounds, Personal Voice. The operating system added restraint primitives faster than the apps running on top of it.

What did not arrive was an app-level expression of the same posture. Almost every product in the category still optimises for daily-active-use, in-app session length, push-notification open rate. The premise — that calm can be optimised — defeats itself the moment a metric appears.

There is a market for a tool that decompresses rather than performs. iOS does it well at the system level. Almost nobody does it at the app level.

The problem

The attention economy has a wellness wing now, and most of it is louder than the noise it is meant to quiet. Trackers, streaks, leaderboards, accounts, terms of service, opt-outs, “personalisation”. A user opens a meditation app to slow down and is greeted with a notification telling them they have not meditated in three days. The mechanism is the same as the slot machine; the framing is the difference.

The people most served by a sensory-decompression tool are also the people most allergic to the design language of mainstream wellness. Adults with ADHD do not respond well to streaks they will inevitably break. Adults with autism do not benefit from gamified breathing exercises. People in the middle of a sensory crash do not want to make an account before they can use the app. The product they need has to do its job on first open, without onboarding, without permissions, without a single screen of marketing.

The privacy story matters too. Wellness data is some of the most sensitive on the device. Most wellness apps ship third-party SDKs that exfiltrate behavioural data to advertising networks the user never agreed to. A tool that promises calm and then ships your nervous-system data to an ad server is, in the end, the opposite of the thing it sells.

The shape needed is a product that does its job and then disappears.

What we built

Five tactile modes, each shaped around a different way a brain might need to slow down.

Release — swipe clutter off the screen. Visual tiles, drag them anywhere, let them fall off the edge. A physical metaphor for the mental act of putting something down.

Focus — sort racing thoughts into order. Three columns, drag-and-drop, no time pressure. The interface lets the user externalise an overloaded working memory onto the screen and rearrange it until the next step is visible.

Breathe — follow expanding rings. A single haptic-paced visual that breathes with the user. No counter, no streak, no “you have completed 4 of your 7 minutes”. The session ends when the user closes it.

Shed — let intrusive thoughts rise and dissolve. The user types or draws a thought; it rises slowly up the screen and fades. A surface specifically for the thoughts the user does not want to keep.

Express — draw freely in a space that does not judge. A monochrome canvas with one finger. No save, no share, no gallery. The drawing exists for as long as the session lasts.

No tracking. No accounts. No gamification. No notifications. No ads. No in-app purchases. No analytics SDKs. Everything runs on the device. Nothing leaves the phone. The privacy policy is approximately one screen long because there is almost nothing to disclose.

The interface is intentionally monochrome — colour is noise, and the whole point is less noise. Typography is restrained. Motion is reduced by default. The icon on the home screen is a single shape, the kind of thing the user can find quickly when they are overwhelmed without having to read the label.

Architecture

The architecture is the inverse of a standard consumer app.

No backend. There is no server. Overstimulated is a native iOS app that runs entirely on the device. No user accounts, no session sync, no remote configuration, no feature flags called from a network.

No analytics. Zero third-party SDKs. No Firebase, no Mixpanel, no Sentry. The app does not know how often it is opened, how long sessions last, or which mode is most used. That information is the user’s to keep.

No persistent storage of session content. Anything drawn in Express, anything written in Shed, anything sorted in Focus is destroyed when the session ends. The app maintains user preferences (haptic intensity, reduce motion) in standard iOS user defaults; nothing else.

Native SwiftUI. The interface is built in SwiftUI to take advantage of native gesture handling, haptic feedback through the Core Haptics framework, and accessibility primitives at the OS level. Reduce Motion, VoiceOver, Dynamic Type and Differentiate Without Color are all respected by default rather than as a settings-menu afterthought.

Compliance posture. Submitted to the App Store with the privacy nutrition label declaring “Data Not Collected” across every category. The app currently makes no network requests, which keeps the threat surface for a sensory-decompression tool effectively zero.

The deliberate trade-off is that there is no growth telemetry. The studio does not know how many people use the app or how often. That is the price of the privacy posture, and the price is fine. The work is in the design, not in the funnel.

How it works (the short version)

• iOS-first, native SwiftUI, monochrome by design
• Five interaction modes; no progression layer between them
• Zero analytics, zero accounts, zero server round trips
• Reduce Motion, VoiceOver, Dynamic Type respected at the OS level
• Free to download; no in-app purchases; no advertising
• Available on the App Store under id6759012134

The product is quiet by design. There are no usage statistics to share because there is no telemetry. Reviews on the App Store skew toward the population the product was built for — short, specific, written by people who recognise themselves in the modes. The marketing surface is the App Store listing and the App Store listing alone.

What’s next

• Additional modes (Q3–Q4 2026). Two further sensory-decompression surfaces in design — one for grounding, one for sleep onset. Same restraint constraints as the existing five.
• Apple Watch companion (Q4 2026). A wrist-level surface for Breathe and a quick-launch shortcut to Shed — both designed to honour the no-notification, no-streak philosophy on a more intimate device.
• Localisation (H1 2027). Translation of the small amount of in-app text into the next five languages, prioritising the regions where the App Store reviews indicate the audience already is.

The roadmap is “more of the same restraint” rather than more features. The product gets better by getting quieter, not by getting bigger.

Tech stack

• Platform — native iOS, SwiftUI
• Haptics — Core Haptics
• Accessibility — Reduce Motion, VoiceOver, Dynamic Type, Differentiate Without Color
• Storage — local-only via iOS user defaults; no persistent session content
• Network — none in the current build
• Analytics — none; “Data Not Collected” declared on the App Store privacy nutrition label
• Distribution — App Store

Status

Live on the App Store. Quiet by definition. The roadmap is “more of the same restraint” rather than more features.

Why this matters for Bento Labs

Overstimulated is the nervous-system compartment of the bento — and the studio’s clearest statement of what restraint looks like as a product principle. Every other Bento Labs product is structurally about evidence, transparency, and verifiable trust (Holt, Holt Agent, Agora). Overstimulated is the opposite: a surface where the user is not measured. Holding both shapes in the same portfolio is the bento philosophy — different compartments, one studio, no contradiction between “trust through evidence” in housing and “trust through silence” in mental health. The thread that joins them is honesty.
