Focused iPhone apps for real-world problems

Notes, planners, timesheets and trackers built around one job each, so there is nothing to set up before you start.

Small-team tools for running the day-to-day: point of sale, reservations, evaluations and sign-in sheets, all working on the phone already in your pocket.

Study timers, flashcards, drills and application trackers for students and anyone learning something difficult on their own schedule.

Expense logs, subscription trackers, budget planners and receipt files that keep your own numbers on your own device.

Logs for habits you are trying to build or break: cold plunges, caffeine, calories and what you eat out.

The small, specific tools you reach for once and then keep: calculators, clocks, scales and password stores.

Home, family and personal record-keeping: inventories, maintenance, prayer times, goals and journals.

Small apps for the moments between things: buzzers, clocks and wallpapers that make a screen more interesting.

Convert, compress and document. File-format work and evidence photos that stay on the device.

Short, sharp games about numbers, timing and judgement — the kind you finish in a few minutes.

Make something presentable without opening a desktop app: badges, thumbnails and daily drawing practice.

Where you have been and where you are going: hikes, countries visited and the aurora forecast.

Readings for people who need the raw numbers: aviation reports and aurora activity, not a friendly summary.

Utilities for people who work with files, servers and text, packed into an interface that works with one thumb.

Keep track of what you buy, what you drink and what is about to go off at the back of the fridge.

Simple records for medication, professional hours and health receipts. These apps organise information; they do not give medical advice.

Timing and record-keeping for the field, the trail and the stable.
