Aviary records that track
the money, not just the birds.
Birds, chicks, pairs, sales, part-payments and dues in one place, in taka, on your phone. For lovebird and budgerigar breeders in Bangladesh.
Free up to 15 birds. Paid plans from ৳199 a month: upgrade on WhatsApp, pay by bKash.
KinBird Aviary's own records live in it: about 100 breeding birds, 180 chicks and 130 sales.
Opens on the money,
then the birds
These are real KinBird Pro screens, filled with a made-up sample aviary. Buyer names are just towns and every taka is invented.
Money first: what is still with your buyers, oldest first, with a WhatsApp reminder and Collect on every row.
Four places an aviary
quietly loses money
Not carelessness. It is what happens when the books live in a notebook and a hundred WhatsApp threads. If money changes hands in your aviary, this is for you.
Dues nobody chases
A buyer pays half and promises the rest. Three months later nobody remembers the number. KinBird keeps every part-payment, ranks who owes you by amount and age, and writes the WhatsApp reminder for you.
Five buyers owing ৳20,000 each is ৳1,00,000 that is not in your bKash.
Chicks sold too cheap
Prices set from memory drift down, because memory is kind to the buyer. KinBird shows each unsold bird's asking price next to a floor worked out from what its mutation has really sold for in your aviary, and lifts the low ones to that floor in two taps.
One chick ৳10,000 under its floor, ten times a season, is ৳1,00,000.
Pairs that should never meet
A brother and sister look like strangers in a cage. KinBird works out the inbreeding coefficient (COI) from the parents you recorded and warns you before you pair related birds.
A wasted clutch costs a season of feed and a cage for months.
Buyers who want proof
A serious buyer asks who the parents were. Print a pedigree certificate, or send a link to the bird's own page with its photos, parents and price.
No proof, and the buyer takes the risk off your price.
The taka figures above are examples, not anyone's real books.
Pay once. Keep the Breeder plan for life.
The first 50 breeders pay ৳5,000 once for the Breeder plan (up to 250 birds), and never pay for it again. When the fiftieth seat is taken, this offer closes.
Breeder billed yearly is ৳4,990 a year, so the seat pays for itself in about a year. Every year after that is free.
The bar counts seats that are paid for. It never shows a number we made up.
Priced in taka,
not dollars
BirdTracks' top plan costs $499 a year, about ৳60,000. KinBird's top plan is ৳9,990 a year. Every plan has every feature: you pay only for more birds.

Your first bird in
about five minutes
Nothing to install. No card. No sales call.
Create your account
Email and a password, and you are in.
Add your birds
The app opens on "Add your first bird". Already keep a list in Excel or Google Sheets? Paste your breeders in.
Run your season
Pair with a COI check, record each sale and part-payment, hand buyers a certificate.
It already runs
a real aviary
KinBird Aviary in Dhaka moved two years of records from Notion into KinBird Pro. Every feature here was needed there first.
Rounded counts only. His buyers' names and his money stay private, the same as yours will.
No quotes here yet, and none invented
New software often fills this space with praise nobody said. This stays empty until real breeders have run a season on it, and then carries their names only if they agree.
Check the maths yourself
The COI calculator and the breeding timeline are free with no account. Try them on pairings you already know the answer to.
Talk to the person who built it
Ayaan answers on WhatsApp himself. Ask anything before you put a single bird in.
What you can hand
a buyer
Made from the records you already keep. Nothing extra to type.
Pedigree certificate
Ring, sex, hatch date, mutations, both parents and a three-generation tree. Print it, or save it as a PDF and send it on WhatsApp.
QR cage labels
An A4 sheet of stickers, one per cage. Scan a cage with your phone to see its birds and its pair.
A page for one bird
Switch sharing on and send the link: photos, parents and offspring. No buyer names, no notes, no money from your books.
Receipt and reminder
Send a buyer what they paid and what is still due as a WhatsApp message, written for you.
What a certificate looks like
Sample bird. The QR appears once you switch sharing on for that bird.
What the alternatives
actually give you
The BirdTracks column is taken from their public website in October 2026. A cross there means it is not on their feature list. If they add it, tell us and this table changes.

Two years of records
deserve straight answers
Before you move your aviary into any app, ask what happens to your data. Here are ours.
Yours alone
Your birds, buyers and money are locked to your account in the database itself, not just hidden on screen. A bird's page is public only if you switch sharing on for it.
Deleted is not gone
Removed birds, sales, payments and customers go to Trash. Restore brings them back exactly as they were, until you empty it yourself.
Take it out any time
Export your birds, chicks, sales, payments, customers, pairs and cages to CSV whenever you want. No form, no waiting.
Encrypted
Encrypted on the way to your phone and where it is stored, on managed servers in Tokyo. Never sold, never shared.
What breeders ask
before they trust it
Do I need to install anything?
No. KinBird Pro runs in your phone's browser, Chrome or any other. Open the site, sign in, and you are working. Nothing to download or update.
What does it cost?
Free up to 15 birds. Hobby is ৳199 a month for up to 50 birds, Breeder ৳499 for up to 250, Pro ৳999 with no limit. Pay yearly and two months are free. Every plan has every feature. Founding 50 is ৳5,000 once for the Breeder plan for life.
How do I upgrade and pay?
Message Ayaan on WhatsApp with the plan you want and the email you signed up with, pay by bKash, and he sets your plan by hand. There is no online checkout yet, and nothing renews by itself.
What happens after 15 birds on the free plan?
Nothing yet: bird limits are not enforced. When they are, you will be told first, and nothing you have entered is ever deleted or locked.
Can another breeder see my birds or my customers?
No. Every record is locked to your account in the database, not just hidden on screen. A bird's page is public only when you switch sharing on for that bird, and even then it never shows your buyers or your money.
Which birds does it handle?
Lovebirds and budgerigars. Records, photos, pedigrees, the COI check, sales and dues work for both. The genetics predictor covers 19 lovebird mutations; for budgerigars, use the free calculator at budgerigargenetics.com.
Can I move my existing records in?
Breeders, yes: paste them from Excel or Google Sheets with a header row (ring, bird_name, gender, birthday, mutations and so on). Chicks, sales and customers are added one by one for now. Founding 50 members get help on a WhatsApp call.
Will it work on my old phone with slow internet?
That is the phone it is built for. Pages are made on the server, photos are sized for your screen, and there are no heavy chart libraries. It does need a connection: there is no offline mode yet.
What if I stop paying?
Your records stay, and you can export everything to CSV at any time. We do not hold records hostage.
Is it in Bangla?
Not yet. The app is in English today. Bangla comes after the English app is finished, done properly rather than half-translated.
Who is behind it?
Ayaan Ahmed Shohan, who breeds lovebirds at KinBird Aviary in Dhaka. He built it for his own aviary first and answers WhatsApp himself.
Still unsure? Ask Ayaan on WhatsApp.
Stop keeping your aviary
in a notebook.
Your first 15 birds are free. The Founding 50 offer closes when the fiftieth breeder takes a seat.
