HormoneOS
HormoneOS is a personal tracking planner for symptoms that move with the cycle: mood, energy, sleep, skin, appetite and pain, each logged against the phase of the month it landed in. It is not a fertility tool and it predicts nothing.
Direct, no marketplace fee. A matching mini-planner is offered at checkout.

What it is for is seeing whether the bad week is the same week every month.
WHAT YOU GET
- Symptom Log - Each symptom rated 0-10 and tagged with the phase you were in. The phase tag is what turns a bad day into a pattern.
- Daily Rhythms - Sleep, movement, caffeine, alcohol and where you are in the cycle. These are the inputs you read the symptom log against.
- Plate - What you ate and which week you ate it in. Not a diet. The tags are here so an easy week and a hard week can be compared on more than feeling.
- Medications - Hormonal contraception, cycle medication, pain relief, supplements. Tick them off daily, and log what you notice after anything changes.
- Works fully offline. Nothing leaves your device. JSON export and import.
