Hemma is a website. There is no app store download, no install permissions to wrangle, no extra storage cost. But you can still pin it to your home screen and let it send you notifications, exactly like a native app would. The setup takes about thirty seconds per phone.
A Hemma icon appears on your home screen. Tap it and Hemma opens full-screen, without Safari's address bar in the way. From here on, it behaves like an app: switch to it from the app switcher, drag it into a folder, treat it like any other.
The icon lands on your home screen. Tap it and Hemma opens like any other app.
Other Android browsers (Firefox, Samsung Internet) have similar menu options, usually labelled "Install" or "Add to Home Screen". Chrome is the most reliable.
Once Hemma is installed (or even if it isn't), you can let it send you notifications. This is what closes the loop: a contractor emails an invoice, Hemma processes it, and a few seconds later your phone buzzes with what changed.
When Hemma has something worth telling you about, it shows a small "Turn on notifications" card on your home screen. Tap Enable. Your browser asks for permission. Tap Allow (the wording differs per browser — anything that lets the request through is the right one).
That's the whole setup. From now on, Hemma can reach you without you having to open it. The notification tells you what happened and tapping it takes you straight to the right place inside Hemma — the document, the budget line, whatever needs your attention.
Browsers are strict about this on purpose. Once you've denied notification permission, Hemma can't ask again — you have to flip it back on yourself.
After flipping the permission, the "Turn on notifications" card reappears the next time you open Hemma. Tap Enable again to finish the setup.
Hemma is built around showing up where you already are. Email, calendar, and now your home screen. The point isn't to make you check Hemma more often — it's the opposite. With notifications on, Hemma only pulls you in when there's actually a decision to make. The rest of the time, your phone stays quiet.
