02apps is a tiny iOS studio building tools people actually open twice. Native SwiftUI, private by default, offline-first — and fast enough that logging a set, a feed or an expense takes a second, not a minute.
Each one solves a single problem for a specific person — and refuses to grow into something bloated. Built, designed and shipped in-house.
The baby tracker built for twins — and singletons too. Log feeds, sleep and diapers for each baby separately, then see them side by side. On-device AI learns each baby's rhythm and predicts the next nap before it happens.
The workout tracker you talk to. Rack the bar, say “bench press, four sets of eight at 225” — logged. It understands real gym slang, catches every PR automatically, and ranks you up from Fresh Meat to Bro God as the plates add on.
Everything a freelancer or small business actually needs, in one fast app. Professional PDF invoices and estimates in seconds, billable hours, IRS-ready mileage, expenses and clients — with reports that show what you really earned.
Logging a transaction is so fast you'll actually do it. Capture every coffee, subscription and splurge before you forget, then see exactly where the money went by category, period or your own tags — in any currency.
If a feature can't earn its place on the first screen, it doesn't ship. Every flow is measured in taps, and we keep cutting until it can't get shorter.
On-device first, offline-first. Your data stays where it belongs, and nothing leaves the phone because it was convenient for us.
Native SwiftUI, no web wrappers, no loading spinners between you and your data. Instant launch, instant logging, instant answers.
We take on a small number of outside projects a year — iOS only, and only when we'd use the thing ourselves. Tell us what you have in mind.
