Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
See when, how much, and from which account every bill is debited. Mark an account funded and get a heads-up if more bills land. No ads, data stays on your device.
Rent, card bills, insurance, subscriptions — do you know which account each one comes out of, and when?
Hikiotoshi shows every upcoming debit by date, amount, and account, so you can set money aside before payday — not after a bounced payment.
No ads. No account. Your data stays on your device.
■ See what each account needs this month
• Add card bills and direct debits, plus recurring payments like rent
• Each account shows how much still needs to be there
• A calendar shows the debit total for every day
■ Mark it funded — and hear about anything new
• Tap an account to mark it “Funded” once the money is in
• If a new bill lands after that, it shows “+$65.00 after funding” and sends a notification
• Optional reminders a few days before each debit
■ Yen and dollars, together
• Accounts and payments can be in dollars (USD) or yen (JPY)
• Mixed totals are converted with an exchange rate you set (Pro updates it automatically)
■ Price went up? Your history stays
• Change a recurring payment “from the next payment” and past months keep the old amount
• Pausing a payment keeps its past debits on record
■ A little guide
• A friendly character tells you what to do next — or turn it off in Settings
• Dark Mode, Face ID app lock, and backup & restore for moving to a new iPhone
■ Made for iPhone Duo, ready for AI
• Open iPhone Duo and the calendar shows this month and next side by side. Tap a day to see its debits on the other page
• Copy your bills in a format you can paste into an AI chat (current subscriptions and this month’s payments). Card and account names can be hidden
■ Pro (one-time purchase)
• Duplicate past payments to save typing
• Monthly check: this month’s total, change from last month, and accounts not funded yet
• 12-month outlook with a chart
• CSV export
• Copy for AI, all ranges: past history, custom dates, upcoming months, and memos
• Automatic exchange rate updates
■ Themes (one-time purchase, sold separately)
• Five extra looks: Graphite, Sakura, Ledger, Terminal, Mono
Exchange rates are estimates and may differ from your card issuer’s rate and fees.
