Coday is a cost per use tracker that works out what each thing you own costs per day. Log what you paid, when you bought it, and how often you use it, and it calculates the daily cost and cost per use. It handles subscriptions and consumables too, and lets you know when something renews, runs out, or pays off. A computer you use every day. A box of daily disposable contact lenses. A subscription that renews regularly. There is plenty worth keeping track of after you buy. Every day, every use, accounted for Track one-time purchases, per-use costs, subscriptions, and consumables. See what each item costs per day, per use, or per unit, record how often you use it, and keep track of quantities used. Costs are based on what you actually spent: money from selling an item is deducted, and paused days don't count. A $999 phone used for two years comes to about $1.37 a day. Clothes and shoes work the same way, for cost per wear. Any currency, one total Give each item its own currency. Totals convert to your main currency, with every payment converted at that day's exchange rate. Subscription tracker, no surprise renewals Log each period's price, the billing cycle, and any free trial, and keep tracking when the price changes.
