Cycle Sync
Read full descriptionHide full description
Your body is not the same every week. Your food should not be either. Cycle Sync reads what you eat and what you take, then tells you how it lines up with the phase you are in today. No calorie guilt, no diagnosis, no lectures. Just what actually supports you this week. SCAN ANYTHING Point your camera at a plate, a packet, or a supplement label. Cycle Sync reads it back in seconds with protein, carbs, fat, and calories, and tells you which phase it suits best. BUILT AROUND YOUR PHASE Menstrual, follicular, ovulatory, luteal. Each one asks for something different. Your picks, your recipes, and your reminders all shift with you instead of staying frozen on day one. VITAMINS THAT MAKE SENSE Log what you already take and see it against the published Daily Value. Set reminders that arrive on the days that phase actually calls for. Cycle Sync never invents a dose. It reads your label, nothing more. SAVE RECIPES FROM ANYWHERE Found something on Pinterest? Import it. Cycle Sync follows the pin to the source, pulls the ingredients, and files it under the phase it fits. SEE YOUR OWN PATTERNS Log a symptom in one tap. Over a few cycles the app shows you which days it clusters around and which foods keep showing up beside it. SYNC WITH SOMEONE Share your phase with a partner so they know what is going on without you having to explain it again. FREE TO USE Log meals by hand and get daily picks for free, forever. Premium adds AI scans, unlimited Pinterest imports, unlimited supplement tracking, partner sync, and more picks every day. PREMIUM $9.99 per month or $59.99 per year, with a one week free trial.

Cilune is a lash atlas for people who get eyelash extensions and can never quite say which set suited them best. It holds the sets you have actually worn and lays them out so the choice becomes obvious. Capture each set right after your appointment, while the lashes are still crisp, or import a selfie you already have. Give each one two quick dials — density and length — and watch it settle onto a two-axis mat. Weeks of blurry memory turn into one readable field: you can see at a glance where you keep landing, which set was the outlier, and which cluster actually suits your eyes. Capture or import each lash set into your own collection Set density and length and place each set on the atlas Dissolve one take into another, aligned by the eyes, to read the drift Pin one set as the keeper you carry to the chair next time The keeper atlas is the heart of Cilune. Pin the set you want again and settle it as a keeper anchor — a small card with its density, length, and your note — so next time you sit down you can point to exactly the look you want instead of describing it from memory.
