Sundial by Tan Girl

Feel your best by tracking your best. Sundial brings cycle-aware peptide protocols, daily logging, and clean supply tracking into one app.

Sundial is the peptide tracker built for women.

Your hormones move in cycles. Your peptides should too. Most peptide apps treat your body like a flat schedule. Sundial treats it like a rhythm.

WHAT'S INSIDE

Today. One calm screen showing exactly what to take, when, and where you are in your cycle.

Stack. Every peptide in your routine. Active doses, paused protocols, supply running low.

Cycle. Phase-aware insights that learn how your body responds across the month.

Library. Vetted peptides with women-specific notes, common protocols, and contraindications.

Journal. Log mood, energy, sleep, and side effects. Build your own data.

WHY IT EXISTS

Most peptide research was done on men. Most peptide apps were too. Sundial closes that gap.
