Short answer: you don't download Lenzic from an app store. Open Lenzic in your browser and install it in one tap: in Chrome on Windows or Mac click the install icon in the address bar, on Android choose Install app from the three-dot menu, and on iPhone tap Share → Add to Home Screen in Safari. It takes less than a minute per device.

Most optical shops and eye clinics run on a mix of devices: a desktop at reception, a laptop in the exam room, a tablet or phone for the owner. Traditional software forces you to install, license and update each one separately. Lenzic works differently. It is a modern web app that installs like a native app, so every device runs the same version with the same data. This guide walks you through each platform, shares practical setup tips from real shops, and ends with a checklist you can follow on day one.
Why Lenzic doesn't need an app store
Lenzic is built as a progressive web app. In plain words, it lives online, but your browser can "pin" it to your computer or phone so it opens in its own window with its own icon, just like any other app. That brings three practical benefits for an optical business:
- No waiting for approvals or downloads. You can set up a new staff device in the middle of a busy afternoon.
- Always up to date. Every time Lenzic opens, it loads the latest version. Nobody in your team works on an old build.
- One account everywhere. A customer registered at reception is instantly visible to the optometrist and the seller.
Step-by-step: install Lenzic on every device
Step 1: Windows and Mac (Chrome)
- Open Google Chrome and go to your Lenzic address.
- Sign in with your Lenzic account.
- Look at the right side of the address bar. Click the small install icon (a monitor with a down arrow).
- Confirm with Install. Lenzic now opens as a standalone desktop app.
- Optional: right-click the Lenzic icon in the taskbar (Windows) or Dock (Mac) and pin it so reception can open it with one click.
Step 2: Android (Chrome)
- Open Lenzic in Chrome and sign in.
- Tap the three-dot menu in the top-right corner.
- Tap Install app and confirm.
- The Lenzic icon appears on your home screen and in your app drawer.
Step 3: iPhone and iPad (Safari)
- Open Lenzic in Safari (this step matters: on iPhone, installing works from Safari).
- Tap the Share button at the bottom of the screen.
- Scroll down and choose Add to Home Screen, then tap Add.
- Open Lenzic from the new icon. It runs full-screen, without the browser bars.

Practical tips for optical shops and eye clinics
Give each role its own device
Install Lenzic on the reception desktop, the exam-room laptop and the sales counter. Each person signs in and works in their own panel. Reception registers the customer, the optometrist records the eye exam, and the seller issues the invoice, all on the same customer file, with no paper passed between rooms.
Put the owner's dashboard on your phone
Owners often install Lenzic on their phone first. From the home-screen icon you can check sales, cash and profit and loss at the end of the day without opening a laptop.
Use Chrome on shared computers
On Windows and Mac, Chrome gives the cleanest install. If the shop computer uses another browser by default, install Chrome once, then install Lenzic from it.
Name and pin the icon
On busy days, staff shouldn't search for the app. Pin the Lenzic icon to the taskbar, Dock or the first home screen page.
Plan for label printing
If you'll print product labels from inventory, install Lenzic on the computer connected to your label printer. Lenzic prints labels directly from inventory with no extra software.
Day-one setup checklist
| ✔ | Task |
|---|---|
| ☐ | Install Lenzic on the reception computer and pin the icon |
| ☐ | Install on the optometrist's laptop or exam-room PC |
| ☐ | Install on the sales counter / label-printer computer |
| ☐ | Install on the owner's phone (iPhone via Safari, Android via Chrome) |
| ☐ | Each staff member signs in with their own access |
| ☐ | Register one test customer and confirm everyone sees it |
Troubleshooting
- No install icon in Chrome? Make sure you're signed in and the page has fully loaded, then refresh. You can also open the three-dot menu and look for Install Lenzic.
- "Add to Home Screen" missing on iPhone? You're probably in a different browser. Open the same address in Safari.
- Opened in a browser tab instead of a window? Launch Lenzic from the installed icon, not from a bookmark.
What to watch next
Once Lenzic is installed, see a full working day in Lenzic, from customer and prescription to invoice and reports, then meet Lenzi, the AI assistant that adds frames from a box photo, barcode or link.
Common mistakes when setting up multiple devices
Most setup problems we see in optical shops are not technical; they are habits. The first is sharing one login across the whole team. It feels faster on day one, but you lose the ability to see who registered which customer or who issued which invoice. Give every person their own access from the start.
The second is running Lenzic in a regular browser tab next to dozens of other tabs. A tab gets closed by accident, refreshed in the middle of an invoice, or buried behind other windows. The installed app opens in its own window and stays out of the way of everything else on the computer.
The third is forgetting the owner's phone. Owners who only check numbers when they are physically in the shop tend to look at reports weekly or monthly. Owners with Lenzic on their home screen look daily, and daily is where small problems such as a cash difference or a frame that never sells get caught early.
Installed app vs. traditional desktop software
| Topic | Traditional desktop software | Lenzic installed app |
|---|---|---|
| Installation | Installer file per computer | One click from the browser |
| Updates | Manual, often skipped | Automatic, always latest |
| Phones and tablets | Often not supported | iPhone and Android supported |
| Data between devices | Network setup or copying files | Same account, same data everywhere |
| New staff device | Hours, sometimes a technician | Under a minute |
For a small optical shop, the biggest win is simple: there is nothing to maintain. You don't need a technician to add a computer, and you never wonder which version someone is running. For an eye clinic with several rooms, the win is that reception, the exam room and the sales counter all look at the same customer file in real time.
