How to use

What machibuse does

Add the works you are interested in, and machibuse watches their prices on DLsite and FANZA side by side. You can see at a glance which store is cheaper, when a sale ends, and whether it is the lowest price ever. No login needed.

Adding works

• Type a title in "Find works", or paste an RJ number or the URL of a DLsite or FANZA work page. Press "Watch" on a result to add it.
• You can also add works directly from "Big discounts that started today".
• When you buy a work, tick "Bought". It leaves the buy-now and change counts and is kept in "Purchases".
• Works that machibuse does not track cannot be added for now.
• Titles are shown in your language when a translation exists. Circle names and sale names are shown as the stores list them.

The panels

• Watch list: prices at both stores side by side. The cheaper one is in bold. "DL" and "FZ" open the store page. Click a row to show that work in "Price history".
• Buy now: works that are at their lowest ever at either store, have a discount of 30% or more ending within 3 days, or have a big price gap between the stores.
• Since last time: how many works dropped in price, hit their lowest ever, are ending soon or ended since the previous data update.
• Which is cheaper: the total if you buy every watched work at the cheaper store, and the difference from the list price.
• Sales now: sales running at both stores and how many days are left.
• Sale coming soon?: an estimate of the next sale based on the intervals of past sales. It is only an estimate and can be wrong.
• Price history: pick a work in the header to see its prices at both stores. You can place as many as you like, and each one remembers its work.
• Purchases: how many works you bought this month, how much you paid, and how much you saved compared with the list price.

Make the screen your own

• Press "Customize" or long-press a panel header to enter arrange mode.
• Grab a panel by its header and move it where you want. Panels in the way move down, and gaps above are filled.
• "W" and "H" change the size of a panel (in cells). "Color" changes its color.
• "Remove" takes a panel off the screen; drag it back from the "Panel shelf" on the right. You can also drop a panel onto the shelf.
• With a keyboard, select the handle with Tab, grab it with Space, move it with the arrow keys and drop it with Space. Esc puts it back.
• "Reset layout" restores the original arrangement.

Saving and moving to another device

• Your works and layout are stored only in your browser. They are not sent to the server.
• The same data is also in the URL after "#". After customizing, update your bookmark (Ctrl+D). Even if you clear your browser data, opening the bookmark brings everything back.
• Copy the code in "Save & transfer", paste it on another device and press "Restore from this code" to get the same screen. You can also export and import JSON.
• "Delete all" removes the works and layout from this browser.

Language

• Use the pull-down at the top right to switch between 日本語, English, 简体中文, 繁體中文 and 한국어. This browser remembers your choice.
