Every consumable at a glance
What’s running low comes first. Restock in one tap.
Tissues, vitamins, contact lenses… Log them by the piece and Coday estimates when each runs out from how you’ve been using it, then reminds you to restock. Every restock price is kept, so the unit cost works itself out.

Lined up by next charge, with a heads-up before each renewal
Streaming, cloud storage, your phone plan… Log each plan’s price, billing cycle and free trial, and keep going when the price goes up. Coday works out what you pay each month and each day and reminds you before renewals and before trials end.

FAQ
Is there an app that works out what my things cost per day?
Coday. Log the price and the date, and it works out the daily cost. Things you use now and then get a cost per use, subscriptions are worked out per billing cycle, and consumables per unit.
How is the daily cost worked out?
(Price + additional costs − what you sold it for) ÷ days owned, not counting days it was paused. For subscriptions, it's the price per cycle × cycles per year ÷ 365.
How do I work out cost per wear for clothes?
Log it as per use in Coday and tap Use once on its page each time you wear it. Cost per wear is (price − what you sold it for) ÷ times worn, so it drops every time you wear it. You can also set a goal and get a reminder when it gets down to a price you pick.
Can it keep track of subscriptions?
Yes. It logs each charge, the billing cycle and any trial, and reminds you before a renewal and before a trial ends.
I have too many subscriptions. How do I keep track of them?
Log each subscription's price, billing cycle and any trial. Coday lines them up by next charge and shows what you pay each month and each day, then reminds you before each renewal and before a trial ends, so you can cancel the ones you don't want in time.
Can it keep track of consumables?
Yes. It tracks your stock and what you paid for each restock, works out the cost per unit, estimates when you'll run out based on how fast you've been using it, and reminds you to restock before you do.
Can it remind me to replace a toothbrush head or a filter?
Yes. For parts like brush heads, filters and racket strings, log how much is left. Coday works out when it's due by time or by number of uses, and reminds you as it gets close.
Can it remind me about warranties and expiry dates?
Yes. It can track warranty, shelf life, return windows and price protection, and reminds you before each one ends.
How is it different from a budgeting app?
A budgeting app logs every bit of income and spending to show where your money went. Coday only logs the things you buy, and works out what each one costs per day and per use, when to restock consumables and when subscriptions renew. It doesn't track income or everyday spending like meals and rides.
Is it free?
It's free to download. Logging items, daily costs, reminders and icons are all free. Premium adds sync across devices, advanced widgets, 200 AI Captures every 10 days, no ads, and more views and colors.
Which devices does it run on?
iPhone, iPad, Android and HarmonyOS. With Premium, it syncs across all three.
Where is my data stored?
On your device by default, and you can use it without signing in. With Premium, sign in and it syncs to the cloud.

Everything you own deserves the rest of its story
Coday is a cost tracker app for the things you own, with four things side by side: cost per day, cost per use, consumables, and subscriptions. See what each thing costs you every day and every use, keep stock of consumables and know when they'll run out, and log every subscription charge with a reminder before it renews. You'll also hear when a warranty or shelf life is about to end, or when something pays off.
Free to download. Premium is monthly, yearly or a one-time purchase.
