Hi! We might open source it at some point, although the app itself is just a thin client, and most of the code is on the battery and the backend

The main concern is confidence that the product will remain usable even if the company goes out of business or pivots and abandons this product. Being a thin client is great from that perspective because there's little incentive to keep it proprietary, and it should be easy for a third party to maintain if the company abandons it.
