About this appAI proposal
Quiet Latch turns a printed QR code into a focus switch. Stick one on your desk, scan it to start a session, scan it again to end it. Each scan can open an iOS Shortcut you control, such as turning on a Focus mode that silences chosen apps and notifications.
It is made for students, knowledge workers and anyone who wants fewer phone distractions without handing app-usage data to a closed service. A plain page lists what is stored, and you can export or delete your session log at any time.
It does not block apps by itself, because a web app on iOS cannot do that. It sets up and triggers the controls iOS already provides, and adds the physical step that makes you pause before you open something else.

- Why this name
- A latch is a simple, visible lock you operate by hand. Quiet points to the calm you want from your phone.

Physical QR switches
Print codes for desk, bedroom or bag. Scanning starts or ends a session, so unlocking takes a deliberate step, not a tap.

What it could be worthEstimate

Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users share a printable code sheet and setup link with friends, classmates or teammates. Anyone who opens it sees the Quiet Latch name and can copy the routine.
- Do they become customers?
- Recipients can sign up and become users, but whether they pay is untested. Test how many link opens turn into set-up routines and then into Plus.
- First customers
- University students on iPhone who already use Screen Time or a blocking app and want a free, transparent alternative.
- Where to reach them
- Student subreddits and Discord: Share the setup guide and a free printable code sheet in study and productivity communities.
- Short video demos: Post 30-second clips of scanning a desk code and starting a focus session.
- Open-source communities: Post on GitHub and Hacker News, explaining the Shortcut-based approach and the data page.
- First milestone
- 200 completed setups and 15 paid Plus users among students within 60 days.

RisksAI inference
- PlatformA PWA on iOS cannot block or read other apps. The product depends on the user building Shortcuts and Focus modes, which may feel like too much setup.
- PlatformWeb NFC is not supported on iOS Safari, so tags are out. Only QR works, which is less tactile than the NFC approach in the evidence.
- CommercialThe evidence is a public claim of cost and trust barriers. Users may prefer apps that block directly, and a free open-source rival exists.
- TechnicalShortcut URL schemes and Focus automations can change with iOS updates and break the setup guides.
- CommercialA scan is easy to skip, so the habit effect is unproven. It needs testing with real users.
