Ticket Heat — Phoenix traffic tickets, crashes and DUIs heatmap with worst-blocks leaderboard

ticket heat checking

Acento — Argentine Spanish accent trainer screenshot

acento checking

Argentine (porteño) Spanish trainer: pronunciation drills plus real lunfardo and the slang Argentines actually post — guita, fútbol, joda, memes, puteadas. Native ♀/♂ es-AR voices, record-and-score, spaced-repetition mastery per category.

grease checking

Pavel's Grease the Groove method, turned into a plan. Enter your max reps for a move and get the sub-max, train-often routine — set size, daily/weekly volume, a clean weekly grid and your next retest date, all calculated. No gym, no soreness.

Handstand — wall-first handstand progression trainer screenshot

handstand checking

A wall-first handstand progression, Kononov-style, turned into a tracker. A 7-stage ladder from wrist prep to a freestanding hold — each stage a measurable hold-time goal. Log your best hold and it hands you today's sub-max practice, then graduates you when you hit the benchmark. No 100-video course you never finish.

The List — NYC pied-a-terre surcharge roll explorer screenshot

thelist checking

New York City published 31,541 properties that may owe its new pied-à-terre surcharge, as a 100 MB pair of zip files. This is that roll, searchable: find an address, see which rate band it lands in, what the surcharge works out to next to the tax already paid, and the routes out — the exemption applies if anyone actually lives there, and the deadlines are in August.

First Bites — baby-led weaning first-foods and top-9 allergen tracker screenshot

firstbites checking

A whole-foods baby-led-weaning tracker. A food board of everything baby has tried with exposure counts and "eat the rainbow" coverage, plus rolling top-9 allergen windows — the acute watch window when you first introduce one, and a maintenance nudge so tolerance sticks. One baby, on your phone, no account.

Baby Signs — baby sign language teacher with animated ASL illustrations screenshot

babysigns checking

Teach your baby to talk with their hands. 110 real ASL signs, each drawn as two pictures — where your hand starts and where it ends — because a sign is a movement, not a pose. Only three to practice at a time, since a wall of thirty teaches nothing. Log what you show and what they sign back, and the app works out which ones have actually landed.
