It's an interesting idea, but needs better explanation. I don't have an iOS device to test the app, but it took me a while to work out what it is and does from the website. The site should explain clearly what the benefits of using it are and why I should use it over another service. It's not easy to get right, but makes a huge difference. I would also spend a bit of time working on the design – you have a good start but it needs polishing. You may not want to go full Google, especially if you're focusing on iOS, but the Material design spec has some really good principles for creating card-based components [0]. I think part of my confusion came from the name. At first I thought it was to do with a Raspberry Pi as [something]Pi seems to be the standard for RPi related projects.
