The time you spend asleep builds World Heritage sites.
Nemtopia is a sleep-sync app that turns your daily sleep into the construction of a diorama.
Depending on how long you sleep, your heritage site will gradually approach completion. Enjoy the changing scenery every time you wake up in the morning as you build your own unique collection.
■ Construction progresses as you sleep
Construction progresses based on your sleep duration, and your World Heritage site will be assembled piece by piece. You can enjoy the changes at each stage as it nears completion.
■ Key features
- Syncs with Apple Health to automatically reflect your sleep data
- Manual tracking using the "Sleep/Wake" button
- Home screen widget to display your current heritage site and construction progress
- Save completed heritage sites to your collection
- Enjoy the excitement of choosing which heritage site to build next to expand your collection
