Offline, ad-free creative play and games for kids

• Fully offline PWA, tested in airplane mode
• 64 coloring pages, freehand and tap-to-fill
• Cloud backup; kids never see a login
• No ads, no tracking, no in-app purchases

Problem

Kids' apps are either ad-funded attention traps or subscription walls, and most of them stop working the moment the wifi does. I wanted something my own kids could open on an iPad in airplane mode: no account, no ads, no upsell, no network.

Strategy

A progressive web app that installs to the home screen and runs entirely offline. Nine activities: freehand coloring and tap-to-fill across 64 line-art pictures, a saved-art gallery, themed word hunts, a math game built on drag-to-feed, a platformer, a plane-dodger, a memory match. Every drawing is a keepsake, so a parent can sign in once and the whole family's art and scores sync across devices. The cast is named after my kids' own words for things: Lellow, Bumbo, Confetti Monster, Aircoo, Gordy.

The bet

Built from zero in one evening as an experiment in how fast an idea can reach a real device, then kept because my kids actually use it. The bet is that a calm, offline, ad-free option with a PBS-grade ethos is rare enough that parents will pass it to other parents. Four families are testing it now.

A movie and TV watchlist that picks what you watch tonight

• One AI pick a night, with the reason
• TMDB-backed list for movies and TV
• Pro tier on Stripe, mobile-first PWA
• The first AvidX product, still shipping

Problem

Streaming platforms recommend what's good for their catalog, not your taste. Your real watchlist is scattered across texts, screenshots, and half-remembered conversations, and the nightly "what should we watch" still burns twenty minutes.

Strategy

Own the list first: one place you control, independent of any platform, with full movie and TV metadata from TMDB. Then make the app open on a decision, not a library. Tonight's pick is chosen by Claude from what you've saved, what you've already finished, and the time of day, with a reason attached. Free gets the daily pick. Pro gets to steer it: time, company, energy, not tonight, pick again, alerts when a show you track drops a new season.

The bet

People frustrated with platform recommendations will keep a personal list if the payoff is a faster decision. This is the first AvidX product built to charge money, and the one proving the whole paid pattern end to end: Stripe, gating, legal, support, the lot.

Gridfinity drawer planner for 3D printing

• Drawer dimensions to baseplate plan in one step
• Rotation, undo/redo, random fill
• Print summary plus JSON save and load
• Client-side, no account, works on a phone

Problem

The bottleneck in Gridfinity organization isn't the printing. It's the planning. Measure the drawer, work out how many grid units fit, figure out which baseplates to print within a 5×5 bed, decide which bins go where, then hope you got it right before committing hours of filament.

Strategy

A single client-side tool. Enter drawer dimensions and get the grid and baseplate split instantly. Place bin footprints on a live grid with rotation, undo, and random fill, then export a print summary and a JSON layout you can reload later. No account, no backend. The whole thing runs in the browser because it doesn't need to be more than that.

The bet

Zero-friction tools win in hobbyist communities. No signup means no barrier: someone can share a link and a new user is productive in thirty seconds. The space has since filled with heavier tools that do CAD export and layout optimizers. Planfinity's edge is the fastest path from drawer dimensions to print list.
