"Wait, who paid for lunch last week?" — this app makes that question disappear.
Tatekae Memo is the simplest IOU notebook for two people. It records just one thing: who covered a shared cost, and how much. No groups, no sign-up, no learning curve. Every feature is free.
■ Log in 3 seconds
Pick a direction with one big button, type the amount, done. Common purposes like "Lunch" or "Groceries" are one tap away. No fumbling at the register.
■ The balance is always clear
Every entry updates the running balance automatically, showing who owes whom in large, easy-to-read type. No more mental math or splitting in your head.
■ Settle up in your chat
Tap "Settle up" to generate an itemized settlement text, then share it straight into LINE, Messages, or any app. When it's paid, reset the balance to zero — your history stays intact.
■ Monthly subtotals
History rolls up by month into lent, borrowed, and net totals — handy for couples and roommates sharing expenses.
■ Your data stays on your device
No account, no network. Records are never sent to any external server.
Great for:
・Couples where one person often fronts shared living costs
・Friends and coworkers who cover each other at lunch or drinks
・Roommates tracking shared household spending
The app is free and shows a banner ad at the bottom of the screen. If you'd prefer a cleaner view, an optional one-time "Remove Ads" purchase is available.
