Ran out of one ink and the printer will not finish the job? Survivor Ink rewrites the page so it prints with the ink you still have. Tell it which cartridges are empty. Every colour on the page is taken apart into the inks it would have needed, the missing ones are removed, and what is left is rebuilt from the inks the printer still holds. Text stays dark enough to read, and colours that never needed the missing cartridge come through unchanged. Black is the awkward one. Send a printer a plain grey and it reaches for the black cartridge — the empty one. So when black runs out, the dark parts of the page are given a colour the printer can actually mix, like the deep blue of cyan and magenta together. That is what makes the ink land on the paper. • Photos, PDFs and pages scanned with the camera • A live preview, before and after • See how much of each ink a page needs, and how much the new version saves • Thin the ink for a draft, or sharpen faint text on a scan • Print, share or save the finished page No account, no ads, and nothing is uploaded. Every page is recoloured locally.

This app lets you view the data from and control your Venstar thermostat locally. Note: "Locally" refers to the fact that your Venstar thermostat has a local API. This app is interacting with this local API. Meaning, unless you have remote mode enabled and are running the companion app on a computer, then, if your phone isn't connected to the same Wi-Fi network as your thermostat, you won't be able to read from it or control it. Data you can view: * Current temperature * Set temperature * Humidity * Mode (heat, cool, auto) * Fan state * Today’s runtime * Runtime for each day of the past week * The average daily runtime for the past week What you can control: * Increase/decrease the set temperature * Change the mode (heating, cooling, auto) * Change the fan mode (always on or auto) Optional push notifications are available to let you know when the thermostat state changes from idle to active (e.g. heating or cooling) or vice versa. These push notifications require the companion app to be running on a computer as well as an API key. More info here: https://thermostat-controller.studiojq.io/push An optional remote mode is now also available, which lets you view your thermostat data while not on the same Wi-Fi network as the thermostat (i.e. from anywhere). This remote mode requires the companion app to be running on a computer as well as an API key. The remote mode is view only. You cannot control your thermostat remotely.
