AviLedger is record-keeping software for bird breeders. Keep your whole aviary — every bird, pair, clutch and chick — in one place, on your phone in the birdroom and on your desktop when you sit down to plan. Works offline. Your records are on the device, so the app opens and keeps working with no signal. Anything you add is saved and syncs automatically when you're back in range. YOUR FLOCK • Full bird profiles: species, ring/band number, sex, mutation, parentage, status, value and photos • Rows and cages that match how your aviary is actually laid out • Import your existing flock from a spreadsheet — no retyping years of history BREEDING • Pair your cocks and hens and track every round • Visual egg board: laid, candling, fertile, infertile, hatched • Candling and hatch dates scheduled automatically from each species' incubation period • Turn a hatched egg into a chick record in one tap GENETICS • Mutation and split inheritance, autosomal and sex-linked • Pairing predictions — see the expected outcomes before you commit to a pairing • Pedigrees and inbreeding coefficients (COI) CHICK GROWTH • Weigh-ins plotted against the species weaning curve • Early warning when a chick falls behind COMPLIANCE & PAPERWORK • CITES and permit records with expiry reminders • Ring/band series tracking • Printable bird passports for sales and transfers FINANCE • Sales and expenses ledger with per-owner totals EVERY DEVICE One subscription covers iPhone, iPad and Mac, with your records synced across all of them.

Move eggs under another pair when a hen breaks hers, and the chick stays credited to the pair that laid it. Bulk edits. Select several birds to set an owner, move them to a cage or row, or ring a whole batch in one pass. A much larger mutation catalogue, and a genetics calculator that now handles dominant and co-dominant mutations, allelic series like the blue locus, and warns you before a pairing that carries a fatal double factor. Fixes a problem that stopped clutches saving and stopped the breeding board loading. ### 1.1.9 — 2026-09-04 Bug fixes and stability improvements. ### 1.1.8 — 2026-08-31 Permits, without the evening of paperwork. The forms a South African keeper actually has to file are now printed from the records you already keep. • The register an inspection asks for. Every bird with its ring, cage, where it came from and when it left, plus movements and escapes, printed per species or for the whole aviary. • The annual return, worked out for you. Opening total, bred, bought, sold, died, closing total and how many cages, per species per year. It tells you what it cannot account for instead of quietly balancing. • The specimen schedule a CITES or TOPS application wants. One table with ring, scientific name, appendix, sex, hatch, source code, F generation, both parents and the permit it came in on. • Permits now name the birds they cover, read from either end. • Your keeper and premises details are kept once and printed on every form. Stats. A new Stats page in the menu: your flock, breeding, money and losses, each figure with its change on last year, and every year side by side. Season summary. How the breeding season went, pair by pair, and whether it beat the last one. Fertility counts only eggs that were candled, so eggs still in the nest are not held against a pair. Set the month your season starts and a season that runs into the new year stops reading as two bad ones. Also in this release: • The web app works offline now, like the phone and desktop apps always have • Scanning a ring reads the number off the photo for you, and you check it • Reminders arrive even when the app is closed • Choose whether the side menu shows on your phone, in Settings • Signing in with Apple no longer asks for a name you have already given • A new aviary now opens on how to get your birds in, instead of asking you to pair birds you have not added yet ### 1.1.4 — 2026-08-25 Works offline. Your aviary now opens instantly with no signal, and anything you record — weigh-ins, clutches, birds, health notes — is saved and syncs by itself once you're back in range. Also in this release: • Faster startup • The paywall now shows the free trial only when the store will actually grant one • Fixed weigh-ins and task ticks that could be lost if a save failed • Smaller download, smoother flock list ### 1.1.3 — 2026-08-21 Works offline. Your aviary now opens instantly with no signal, and anything you record - weigh-ins, clutches, birds, health notes - is saved and syncs by itself once you're back in range. Also in this release: • Faster startup • The paywall now shows the free trial only when the store will actually grant one • Fixed weigh-ins and task ticks that could be lost if a save failed • Smaller download, smoother flock list ## More apps by Elcolynx - [Loadem](https://appshunter.io/ios/app/loadem/id6758661743) - [Wobble Care](https://appshunter.io/ios/app/wobble-care/id6767207763) All apps by Elcolynx: https://appshunter.io/developer/1874248573 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
