Wristy show the temperature at your wrist as widget on your homescreen! NOTICE: This data is only gathered if you wear an Apple Watch Series 8 or Ultra while sleeping. If you don't have such data yet the widgets will show you a random preview of their functionality. The app allows you to authorize the data from HealthKit and shows it as a small, medium or large widget on your homescreen. It is kept plain and simple by design and includes only the most necessary things. In the near future I plan to add other data but the temperature at your wrist from HealthKit into the app to make even more widgets possible – but first things first. The app as well as the widgets fully support darkmode and are available in english and german.

Verdict
The clearest difference is price: NAIA at Free against Wristy's $0.99. NAIA also leads on update cadence (every 4 days vs every 8 months) and iOS requirement (13.0 vs 16.0). On ads, in-app purchases and device support there is nothing between them.
