The currency converter and installing the site as an app: two small everyday tools

This post is about two small tools — both are used daily and neither needs an account.
1. The currency converter
Where: /currency-converter; on wide screens the "Converter" link next to "Currency" in the header row, on narrow screens in the "More" menu; in the mobile app, the "Currency" section.
How it works: the converter uses the official rates of the Central Bank of Azerbaijan for the day — the date is shown at the top. Type an amount, pick the base currency, and the result is computed instantly. With "Add currency" you compare up to 6 currencies at once; type a number into any row and the calculation runs in reverse — for example from manats to dollars. There are quick-amount buttons, "Copy result" and a currency search (by code or name, over 40 currencies).
Popular pairs have their own pages — USD → AZN, EUR → AZN, RUB → AZN, TRY → AZN and the reverse: a ready conversion table (1, 5, 10, 100… units), the rate history for recent days and the trend. Today's rate table itself is still on the Currency page — the two pages differ by the question: "how many manats is 100 dollars" goes to the converter, "what is today's rate" goes to the table.
2. Installing the site as an app
Where: "Install the app" in the mobile menu and the footer; in a desktop browser, the install icon in the address bar or the site's own prompt card.
How it works: Prayk is now an "installable" site. On Android, choose "Install app" in the Chrome menu (⋮); on iPhone, in Safari choose "Share → Add to Home Screen" — the site appears on the home screen with its own icon and opens without browser bars. Long-press the icon and shortcuts appear: Post a listing, Messages, Favourites, Search. When the network drops, an explanatory page shows instead of a blank screen. This is not a separate download — it is the site itself: it takes no space and updates by itself.
On a phone our main recommendation is still the native app — push notifications and camera integration are complete there. The installed site is the closest alternative for computers and for those who do not want to download an app.
All together
Install Prayk on your computer and keep the "Converter" open — comparing a listing price in dollars takes two clicks. About the other everyday tools (rates, crypto, metro, map): "Prayk's everyday tools".
