Coday keeps track of what you own, with four things in one app: 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. 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. Extra costs like accessories, fuel, or vet bills, and recurring costs like car insurance or vaccinations, are spread into the item's average too. 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. Consumables and stock, before you run out Track stock and what you paid for each restock to get the cost per unit. Coday estimates when you'll run out based on recent use and reminds you to restock. For parts that wear out, like toothbrush heads, filters, or racket strings, it tracks what's left and works out when to replace them, by time or by number of uses. Subscription tracker, no surprise renewals Log each period's price, the billing cycle, and any free trial, and keep tracking when the price changes. Get reminded before a renewal or before a free trial ends, and see what each subscription costs you per day. AI Capture: hand Coday an order screenshot AI reads the name, price, date, and currency, and finds a matching icon, so the item is logged in one go. Sign in for 1 free capture a day, or 20 a day with Premium. 10,000+ beautifully crafted 3D icons From electronics to everyday essentials, find an icon that fits each item, and AI gives every item card a harmonious color. Know when it renews, runs out, or pays off Get notified when an item reaches your target average cost, before a subscription renews, or when it is time to restock everyday essentials. Warranty, shelf life, return windows, and price protection get a heads-up 7 days ahead by default. Regular care like servicing or vaccinations, duration goals like wearing a coat for three years, and custom dates like a contract ending are covered too, and items can retire automatically when they expire or run out. A glance at your Home Screen See each item's daily cost and progress without opening the app, and check your total spending with the stats widget. Premium adds rotating and pinned item widgets. Pick up on any device With Premium, your records stay in sync across your devices. Log it on your phone, pick it up on your tablet. Wishlist and dashboard Put things you want on your wishlist, wait a few days before deciding, and see how much you saved on what you let go. The dashboard on the You tab brings this month's spending, reminders, your wishlist, consumables, and subscriptions together, with a timeline to look back on. Custom fields hold anything else you care about, like the model or where it's kept. Free to use, no account needed Free to download, with unlimited items. Logging, cost per use, reminders, and icons are all free, and you can use Coday without signing in: your data stays on your device by default. Premium adds sync across devices, rotating and pinned widgets, 20 AI Captures a day, no ads, and more views and colors. Everything you own deserves the rest of its story.

Verdict
The clearest difference is in-app purchases: 30000days at none against Coday's 3. Coday's advantage is update cadence (weekly vs monthly) and device support (4 vs 2). On price and ads there is nothing between them.
