Google will run your private app. Your buyers still cannot install it.

On 13 October 2026, Sam Bright at Google Play described a change that is easy to overread. Using Google AI Studio, a person can build a custom Android app and run it on their own phone through Google Play. They need a normal Google account, not a developer account. The app stays private, off the public catalog. The rollout starts in select markets, including the United States, for people 18 and over.

A private app on one phone is not an app a customer can search for and install.

Google says sharing with a close circle of friends and family comes in the coming months. If the owner later wants the public to have it, they move to a professional developer account. The app then goes through the same Trust and Safety reviews and the same quality standards as every other professional app. Google still decides whether that public listing is accepted. If the job also names the App Store, Apple still decides. A written plan can include the submission. It cannot include a promise that either store will say yes.

The same post adds discovery tools that sit beside this. Ask Play can compare apps and surface differences, including what users say about them. Play in Gemini will bring Play's apps, games, and developer pages into Gemini chats, and Google says that will start rolling out to Gemini users soon. Game Finder, built around what Google calls Gamer DNA, is for games. It rolls out in English to users in the United States first. Those tools change how a person picks among apps that already exist. They do not write your screens, your prices, or the rule a warehouse uses when a box arrives short.

Split the job before anyone celebrates a demo.

A private prototype is a way to see an idea on a device. It helps when you are still deciding what the app must do. It is a poor place to stop if a cashier, a driver, or a buyer in another city must use it on a Tuesday. They cannot find a private app in the public store. A screenshot in a chat group is not distribution.

A company app starts as a document. The written plan names what the app does, and the price, before we start. It can name iPhone, Android, or both. It can name a camera, a location check, or a notification. It does not include a fingerprint reader unless that job asks for one. After handover, we fix faults in the agreed work for at least 3 months. New features are not part of that cover. Care after the store listing, if there is a listing, is whatever the plan wrote down.

Some company jobs should not start on Play at all.

If the work is a checklist, a stock count, or a sign-off that already lives in a spreadsheet, an AppSheet app can sit on the sheets you already use, on a phone or a tablet. Anton Maulana leads that work. He holds Google's advanced AppSheet certificate on Coursera. The plan still names what the app does, and the price, before we start. Data can stay in Google Sheets, Excel, Cloud SQL, or PostgreSQL, as that job requires. Offline capture is in the plan only when the plan says so.

If the work is a desk with a receipt printer, a barcode scanner, or a scale, that is a desktop app. The plan names the equipment. We do not buy the hardware. Kasir Kita, the ready-made cashier, is a product you can try in the browser. A desktop app built around your own rules is a different job, with its own plan.

If the buyer only needs to read what you sell, and your team needs to change the words, that is a company website. The plan names the pages, the price, and who owns the code before we start. Someone can open it on a phone and on a computer. We do not promise a load time for every country.

Ask Play will not choose among those paths. A comparison of public apps is not a specification of yours. A private build that impressed one manager is not a scope.

Do this before you spend a month polishing a toy. Open the private app and write one sentence: what it does. Then write a second sentence: who else must use it next month. If the second sentence is only you, leave it private. Google built that path on purpose. If the second sentence names a customer, a branch, or a shift, the next step is a written plan.

Tell us what you need. We reply by the next business day, Monday to Friday. You see the plan and the price, and you agree them, before we start.
