We aren't full of crap you don't need, especially a monthly subscription. 

Small studio. Real problems. No fluff.

BigBunny LLC builds focused iOS apps for people who have a specific job to get done and want a tool that respects their time. We are not interested in engagement metrics, notification spam, or growth-hacking. We are interested in software that works.

Every app we have built started from the same place: a real person trying to do something specific — track a swim meet, scan a receipt, organize a collection, manage a rental — and finding that existing tools were either too heavy or too thin.

We fill that gap. Quietly. One app at a time.

OUR PHILOSOPHY

"The best tool is the one you don't have to think about."

We build for depth, not breadth. Every BigBunny app does one thing extremely well, gets out of the way, and keeps your data on your device. We believe software should earn its place on your home screen — and that means shipping features users actually asked for, not features that make a press release sound good.

Our apps are honest about what they cost. A small one-time Pro upgrade. No subscriptions for things that don't need them. No ads. No account required. Just the app, doing the job.

WHAT WE'VE BUILT

Our Apps

01 — UnitKeeper

Property Management

Track units, properties, and tenants in one place. The app that started the studio — a landlord's alternative to spreadsheets and expensive SaaS platforms.

02 — SourceKeeper

Academic Citations

Scan a barcode or photograph a journal page and get a formatted citation in Chicago, MLA, or APA. For students who are tired of doing this by hand.

03 — SplitDeck

Swim Coaching

Multiple stopwatches, one screen. Record splits across every lane simultaneously, then export the results. Built for pool decks, not offices.

04 — FunFX

Soundboard

A fully customizable sound trigger app with curated packs, custom imports, and pro audio editing. For educators, performers, and anyone who loves a good button.

05 — Becky's Receipts

Personal Finance

Scan receipts, track payments, and export your data as a CSV. A clean, no-fuss personal expense tracker for people who know what they need.

06 — Sortifact

Collection Management

Catalog anything — records, trading cards, vintage cameras, books. Custom fields, photos, and categories that adapt to whatever you're collecting.

WHAT CONNECTS THEM

Six apps. One set of principles.

Six apps, six very different domains — but look at any two of them and you'll see the same DNA.

01 — One clear job

No app tries to be a platform. SplitDeck times lanes. Becky's Receipts tracks receipts. The name tells you what it does.

02 — Your data stays yours

Local storage by default. CSV and export built in from day one. No account. No cloud lock-in. If you delete the app, you still have your data.

03 — A free tier that actually works

Every app ships with a usable free tier. Pro unlocks more, not the basics. We'd rather earn your trust before we earn your money.

04 — Built for the person doing the thing

We don't design for the app store screenshot. We design for the landlord at the desk, the coach at the pool, the student at midnight before a deadline.

05 — Honest pricing, one time

Every Pro upgrade across our catalog is a non-consumable one-time purchase. No subscriptions for software that doesn't need a server.

WE WROTE THE BOOK — LITERALLY

Ship It

A Practical Guide to Building and Launching Your First iOS App

We turned our process into a published guide. It covers everything from validation and AI-assisted development to App Store Connect, in-app purchases, and post-launch iteration. If you're building your own thing and want to skip the walls we ran into, it's on Amazon Kindle.
