Churnie: Card Churn Tracker

v1.3 · Cashback iOS & Android · Finance

The bonus game, won.

Australian banks pay big sign-up bonuses, and take them back from anyone who slips. Churnie is the discipline layer. Add a card in 30 seconds and it paces the minimum spend in dollars per day, reminds you at 14, 7, 3 and 1 days, holds the cancel-by date with a cancel-day checklist, and since 1.3 tracks cashback right next to the points. The Radar leads with the deals worth chasing now and checks every AU bank's exclusion window against your history, shared windows and 18-month rules included. A timeline shows every fee cliff months ahead, and a lifetime ledger proves the hobby pays. Free, private, no bank logins, no card numbers.

One job, done stupidly well.

Squish: Video Compressor

Featured v1.2 · iOS & Android · Photo & Video

See the size before you squish.

See exactly how small a video will get before you compress it: pick Small, Balanced, High or Max, or name a target size, and the estimate updates live. Then squish. Batch as many as you like, keep the date and location on the result, delete the originals to reclaim the space, and watch the savings add up in History. No watermark, no size cap, no daily limit, no ads, and nothing is uploaded: it all happens on your phone. Squish Pro adds max quality and MP4, MOV and GIF conversion.

The Wharf WOD Timer

v1.1 · Fresh chalk iOS & Android · Apple Watch · Health & Fitness

Three. Two. One. GO.

The gym timer that yells GO like it means it. AMRAP, For Time, EMOM and Tabata, with digits you can read from the other end of the garage and a coach's voice calling the moments that matter: the countdown, halfway, last round and the final 5-4-3-2-1. Three voices to pick from, or shuffle them and let fate coach you. Cues punch straight through the silent switch, the screen stays awake for the whole workout, and if you lock your phone mid-WOD the rounds don't drift a second. It runs on the wrist too, with the Apple Watch app. Free, no account, no ads. Chalk up.

The Trackers · 2

They remember things so you don't.

Loglet: Symptom Tracker

v1.4 iOS & Android · Health & Fitness

Remembers, so she doesn't have to.

The doctor asks how you've been, and a month of bad nights evaporates into "fine". Loglet remembers so you don't have to: one-tap cramp logging that works half-asleep at 4am, guided sitting-then-standing blood pressure that flags the drop when you stand, as many readings and notes a day as you like (with a time on anything you enter later), and medicine ticks that handle split doses and Mon/Wed/Fri schedules. Come appointment day, one tap turns weeks of symptoms, doses, readings and notes into a clean PDF that answers the real question: is the dose right? Built for the developer's mum and her heart, which is why it's all big text, big buttons, three plain tabs and no jargon. Free, no account, no ads, and your data never leaves your phone.

Menopause & Hot Flash Diary

v2 · Diary + Petals iOS & Android · Health & Fitness

Dear diary, a tap is all it takes.

Version 2 turned a symptom tracker into a diary. The page greets you by name; you tap what you had (hot flash, night sweats, sleep, mood, eleven in all), say whether it was a bud, a bloom or a full flower, and it is written down with the time. The calendar fills with petals, so a rough week shows from across the room. Patterns tells you what is changing and when. And when the appointment comes, one tap turns any stretch of days into a one-page report in plain clinical language, ready to hand to your GP. After dark it dims to the small hours. No account, no cloud: your diary stays in your pocket. The diary itself is free forever; Premium adds the longer look back and the PDF.

How we build

We can't sell what we never collect.

Minimal data, no tracking, nothing sold. Our own apps go further still: no accounts, and nothing leaves your phone.

Shipped, not slideware.

Real apps in the store, real web apps in production. We design, build, and ship the whole thing, then keep it sharp after launch.

Small on purpose.

Tight scope, sharp execution. Every screen earns its place, so the app stays fast and stays out of your way.
