About this app

Who remembers to buy toilet paper? Who pays for the groceries up front? Who owes what to whom after the weekend away with friends? Cotcot answers these questions without the arguments, with the numbers to back it up.

Couples, families and roommates share household chores, expenses, the shopping list and the calendar in one place. And everyone can finally see how the mental load is shared.

⚖️ THE BALANCE INDICATOR: THE MENTAL LOAD, FINALLY VISIBLE
The mental load is everything you plan ahead without anyone noticing. Cotcot measures it from what the household actually does in the app, on three axes:
• Organization: who thinks of the tasks and adds to the shopping list
• Execution: who does the chores and the shopping, weighted by the effort of each task
• Money: who pays up front for shared expenses
You get a clear verdict (balanced, fairly balanced, imbalanced), concrete tips to rebalance, and the period of your choice: this month, this year or since the beginning. A calm way to talk about who does what, without blame.

💸 SPLIT EXPENSES IN PROPORTION TO INCOME
A 50/50 split isn't always fair when incomes are different. With Cotcot, each household picks how to split its expenses:
• Equal shares
• Proportional to income: with incomes of 2,500, 2,200 and 1,800, the groceries are split 41%, 36% and 23%
• Custom percentage
Rent, bills, groceries, nights out: Cotcot works out everyone's share on every expense and keeps each member's balance up to date. You know who owes what to whom, and paying each other back is simple.

🐔 COTIZ: SPLIT BILLS WITH FRIENDS, FREE AND NO ACCOUNT NEEDED
A weekend away, a vacation, a dinner out, a group gift? Create a Cotiz in seconds, with no sign-up and no subscription. Share the link: your friends open the Cotiz in the app, pick their name and add their expenses, without creating an account. Cotcot works out the total, the average per person and the reimbursements needed so everyone is square. Equal shares, proportional to income or a free split: you choose.

🧹 HOUSEHOLD CHORES AND TASK PLANNING
Create a to-do list, assign chores (dishes, trash, cleaning), set a due date and tick it off when it's done. Every completed task counts in the balance indicator, for a fairer split of chores day to day.

🛒 SHARED SHOPPING LIST
One shopping list for the whole household. Whoever stops by the store has the right list, and nobody buys the same thing twice.

📅 SHARED CALENDAR AND FAMILY PLANNER
Dinners, appointments, birthdays, weekends away: everyone answers "I'll be there", "Maybe" or "Not attending", so everybody's in the loop.
