I build small iPhone apps on my own. Each one is a single idea carried through: one job, done on the phone you already have in your hand.

On the job

Field tools for trades. Measure, prove and hand the client a document before you leave the site.

GasTest LogTime the code-required gas pressure hold, prove it with gauge photos, hand over a cited PASS/FAIL certificate.

DrainReportTurn a sewer camera run into a report the homeowner actually understands.

FloorQuoteScan a room with LiDAR, price floors, walls and ceilings, hand over a quote on site.

BoulderLiftScan a rock and know whether your machine can lift it.

Everyday

Small single-purpose tools that open, do the one thing and close.

TrueLevelA pocket spirit level that also reads pitch and roll in degrees.

AltLogOne-tap elevation log from the barometer in your iPhone. No GPS.

WhisperNoteWhisper a note and it becomes text — a normal voice is ignored.

QuietSeaAmbient noise generated on the phone in real time, not played from files.

BreathePulseA breathing pacer you follow by touch, with your eyes closed.

Focus PostureA focus timer that notices, through your AirPods, when your head drifts forward.

Foldeon in developmentA diatonic button accordion where the phone is the bellows: tilt any iPhone with iOS 18 or later, or fold iPhone Duo.

PocketBeatA metronome you feel through the Taptic Engine instead of hearing.

PitchGardenA chromatic tuner that blooms as you come in tune, plus a daily ear trainer.

GiftwiseBirthday reminders, gift ideas and wishlists for the people you give to.

SolarDialSunrise, sunset and the golden hour for where you stand, on one dial.

TallyTouchA tally counter you can run without looking at the screen.

Gatelight in developmentCheck whether your car may enter a French low-emission zone (ZFE) now or at the time you choose.

Money

Trackers and calculators for saving. You enter the numbers; nothing connects to a bank.

Pennyjar in developmentOne app for the money you set aside: a jar for every savings goal, the 52-week and 100-envelope challenges, and your emergency fund in months.

Taxes

Tax estimates from the documents you already have, with the rule and its source shown. Informational, not tax advice.

Taxenda in developmentYour month's ISR and IVA under Mexico's RESICO regime, worked out from your own CFDI XML invoices, with the deadline and the 3.5 million limit.

Games

Short daily puzzles and tests, built around one rule each.

GlintA daily light-up logic puzzle you can feel.

LooplingPuzzles where your teammate is a recording of you.

ReflexTapWait for green, tap fast, read your reaction in milliseconds.

NorthsenseA 90-second daily workout for your sense of direction.

PickfallDrop a pickaxe into the shaft, time perfect strikes, and grow a village from the ore. Free, with optional ads and one purchase that removes them.

OrikomiOrigami puzzles where the fold line stays still: slide the paper onto it and fold — with a knob on any iPhone or iPad, or with the hinge of iPhone Duo.
