A focused habit tracker built around the 66-day habit model
Somnus analyses 25+ signals from Apple Health to find the specific habits that drive your sleep quality. Not generic tips — your actual patterns from your actual data.
Most sleep apps show you a score and some charts. Somnus tells you why one night was great and the next wasn't. Things like: you sleep better when you go to bed between 11 and 11:30, or your sleep quality drops when you skip exercise two days in a row.
You can create your own signals using natural language and on-device AI. Ask "how does coffee affect my sleep?" and it builds the analysis from your health data.
Found a pattern? Run a structured sleep experiment with automatic adherence tracking and before-and-after comparison.
Built solo by an indie dev. All AI runs on-device using Apple's FoundationModels. No cloud, no accounts, your data never leaves your phone.
