## What is Koi Coin?

Koi Coin turns this month's spending money into a tank of koi. Every fish in the tank is money you still have, so a glance tells you how much is safe to spend today.

Log a purchase and fish of the same value turn into coins and swim away. No complicated ledgers. Just take care of today.

With simple gestures:
• Swipe up to add an expense
• Swipe right to look back at every day's little tank
• Swipe left to bag big expenses like rent or trips ahead of time
• Swipe down for coin stacks and spending insights

Koi Coin Plus unlocks full history, more future plans, and complete insights. Monthly and annual plans renew automatically. Lifetime is a one-time purchase. Prices may vary by App Store region.

Privacy by default: no account, no ads or third-party analytics. Your records stay on your device.

## Version history (last 5 releases)

### 1.6.1 — 2026-10-25

· Fixed a crash that could happen right after buying Plus.
· Stability improvements.

### 1.6 — 2026-10-21

· New spending stats: see each day of the week, month or last 3 months against your daily allowance. Tap a day to see what you spent.
· New records page: browse by week, month, 3 months or everything, jump to a day, filter by category and search.
· Add entry now sits in Today's card, easier to reach; scroll up and it becomes a small + that's always there.
· The cat hides behind the cards and peeks out as the page moves.
· Swiping between pages is smoother, the fish keep swimming while you swipe, and side swipes no longer trigger taps.
· Tap a thing on the table and the cat walks over and takes on its mood, each with its own walk; double-tap to bring it back.
· New settings: keep the cat grounded when you shake or tilt, and choose how many decimals today's number shows.

### 1.5.2 — 2026-10-12

· A tag now hangs on the bowl: tap it to have the fish show what's left this month or today's share.
· Swiping from Today to the tank history is smoother.
· The tank's sound no longer follows the silent switch; use the sound toggle in the app.
· The water only rumbles when you shake the phone or touch the water.
· Fixed layout on small screens, with long currency symbols and with large text.

### 1.5.1 — 2026-10-12

A smoother tank: fixed a small hitch that interrupted the fish once a second.

### 1.5 — 2026-10-11

Log a purchase and the cat acts it out.
• Everything you log today drops in from the top of the screen and becomes a little thing on the table: a rice bowl, a shopping bag, a toy car, a cushion, a ball of yarn, a box. Tilt or shake your phone and they slide around; tap one and the cat comes over to play
• The cat walks over, acts out what you just logged, and stays in that mood until your next entry: patting a full belly, cruising in its toy car, curled up in a box…
• Choose which day your month starts in Settings, and see the current cycle's dates right there
• Tap today's amount left to see how it's worked out
• Display fixes
