KuraKuraA ledger for gear and subscriptions

Cameras, lenses and subscriptions, in one ledger

What are the things you own costing you this month?

Gear you paid for once becomes a cost per day — the price divided by the days you've owned it. Subscriptions become a cost per month, with yearly plans spread evenly. Two things you used to count separately, on the same scale, as one number.

App Store Coming soon How it works

On the App Store it is listed as “Kura 蔵”.

An iPhone app. The overview and monthly summary are free; a one-time purchase lifts the limits and turns on charge and expiry reminders.

Kura

The number

What you paid once and what you pay monthly, as one number

Gear, per day¥1,590/ day × 30 days
Subscriptions, per month¥17,043/ month
Holding cost this month¥64,743

Sample figures. Per day = price ÷ days owned; yearly plans are divided by 12.

Gear

What each piece costs you per day, since the day you bought it

The price divided by the days you have owned it. The longer you keep something, the lower it goes — not as an excuse for an expensive lens, but as a way to see what keeping it is worth.

01

Cost per day

Price ÷ days owned. Sort the list by cost per day or by purchase date.

02

Warranty expiry

Keep the manufacturer and extended warranties separately. You're reminded 30 days before each ends.

03

Your gear on the same mount

Open a body to see the lenses you own for its mount. Open a lens to see the bodies it fits.

04

Shutter count and maintenance

Log the shutter count with the date you read it. Keep sensor cleanings and repairs, with their cost.

05

Photos and receipts

Keep photos of the gear and its receipts together. Serial numbers show only the last four digits until you tap.

06

When you let it go

Enter what you sold it for and Kura shows what owning it really cost. Sold or lost items leave this month's holding cost.

Subscriptions

Know before you're charged

Streaming, AI, servers, domains, membership fees. Monthly, yearly, foreign-currency and usage-based charges, in one list.

01

Before each charge

Choose per service: same day, or 1, 3 or 7 days before. On the 1st of each month, a summary of the previous month arrives.

02

When a free trial ends

You're reminded 2 days and 1 day before the first paid charge, so fewer trials turn into payments you didn't notice.

03

Card expiry

Note which card pays for which service, and when a card is about to expire, Kura lists the services you'll need to update. Only the last four digits are kept.

04

Foreign currency and usage-based billing

Charges in other currencies are converted with reference exchange rates. Enter the amount from your card statement and that charge uses the actual figure.

05

Months with a yearly charge

“Charged this month” and “monthly average” are shown separately. When a yearly plan makes this month higher, one line says which one.

06

Maybe unused

Services you mark as rarely used appear on the overview, with what they add up to over a year.

Apple Watch

Just the reminders, on your wrist

There is no Apple Watch app. Notifications from your iPhone are passed to your wrist while the iPhone is locked — the monthly summary, charge reminders and trial endings alike.

While you are using your iPhone, notifications appear on the iPhone instead of the watch (this is how iOS works). Delivery is also handled by iOS, so a notification may not always arrive.

Privacy

Your records stay on your device

No account

No sign-up and no sign-in. Gear and subscriptions are stored on your device.

Only exchange rates go over the network

The only thing that leaves your device is a currency code, when rates are fetched. Names and amounts are never sent.

Only the photos you pick

Kura doesn't ask for access to your whole photo library. The photos you choose are resized and stored on the device.

Pricing

Looking is free. One payment lifts the limits and turns on reminders.

Without buying

The overview, currency conversion, and the monthly summary and trial-ending reminders work without buying. Over the limit, everything you've added stays visible and editable.

FAQ

Questions

Do I enter subscription prices myself?
Yes. The service templates (Netflix, ChatGPT and so on) carry only a name and a category, not a price. Prices vary by country and change over time; an outdated default would quietly make the totals wrong for anyone who saved without checking.
Which currencies can I use?
The 17 currencies for which the European Central Bank publishes reference rates, including JPY, USD, EUR, CNY, HKD and KRW. The New Taiwan dollar isn't among them, so it can't be selected for now.
Will converted amounts match my card statement?
Not always. Reference rates differ from your card issuer's rate and fees. Enter the actual amount from your statement and that charge is totalled with it.
Are notifications guaranteed to arrive?
Kura schedules local iOS notifications, but delivery is handled by iOS, so it can't promise every one will arrive.
Is it a subscription?
No, it's a one-time purchase. There's nothing to cancel.
Where is my data? Can I sync between devices?
On your device. Nothing is sent to a server. There is currently no sync between devices, and deleting the app deletes its records. Before changing phones, export a backup from Settings.
How do I get a refund?
Purchases are handled by Apple. Please request one at reportaproblem.apple.com.
