“HomeRoutines Vintage” is what was the iPad-only version of HomeRoutines, before we saw the light and made the app universal.
We have left this version in the App Store as a courtesy to people who bought HomeRoutines for iPad in the past, so we can continue to send them updates. It is identical in every way to HomeRoutines.
We gave it a sucky-looking grey icon in the App store to try and shoo away new customers, not that there is anything wrong with the app.
The icon will be its usual cheerful colours on your device.
