75 Hotter Today screen: 2 tasks left, luteal phase, your circle

Every day

Six tasks. One day at a time.

The classic 75: two workouts, one of them outside, a clean diet, a gallon of water, ten pages and one photo. Tick them off as you go. When all six are done, the day is closed.

  • Drink 1 gallon of water
  • Eat clean, feel radiant
  • 45-minute workout
  • Second movement outdoors
  • Read 10 pages
  • Daily photo
Your cycle: luteal, day 22 of 28, with all four phases

Cycle-synced

Same rules. Smarter effort.

Tell the app when your last period started. Every day it reads your phase and adjusts the advice, never the tasks. Hard intervals when you’re strong, steadier days when you’re not.

  1. PeriodDays 1–5Go by feel, then train strong.
  2. FollicularDays 6–12Build. Energy is on your side.
  3. OvulationDays 13–15Strong. Warm up a little longer.
  4. LutealDays 16–28Steady days. Go lighter, eat enough.
  • Your cycle never leaves your phone.
  • The moon is there for fun. Tips only come from your cycle.
  • Wellness guidance, not medical advice.
