follow.fast runs social media for apps. Paste an App Store link and it pulls in the name, icon, description and screenshots. Every day it drafts slideshow posts from the app's real screens and the push notifications the app really sends, rendered on a phone in the scene, and publishes them to TikTok, Instagram, Facebook, Threads and Bluesky. Approve the queue with one click, or switch on autopilot.

I built it because I ship apps and never had time to post about them. It has posted daily for four of my own apps since October 2026, across twelve slideshow formats: persona stories, notification stories, listicles, myth vs fact and more. Formats that beat the median get picked more often and the rest get retired. Any slide can be edited before it goes out, and the 4:5 feed and 9:16 TikTok versions update together. Currently in private beta.

Puddlekin is a baby tracker built for the people taking turns. Feeds, naps, diapers, pumping, tummy time and notes go in with a few taps, timers keep running when the app is closed, and anything can be backdated. Today shows what's running and when the last feed, sleep and diaper happened, so nobody has to remember at 3 am.

All logging is free and stays on the phone, no account needed. Puddlekin Premium adds shared care: invite a partner, grandparent or nanny, approve every request, and see who did each feed. It also adds cloud restore, a 6, 12 or 24 hour Handover summary, and 7 and 30 day trends. It records care and never prescribes it: no ideal ranges, no "overdue", no predictions.

Gutrude is a poop tracker and trigger food log with a character: your gut, in a cardigan. Cranky, and she keeps the file. Log a poop in three taps, tap in meals and drinks, and when something sits badly, blame the food you suspect in one tap. Gutrude keeps score on your suspects and tells you honestly whether the numbers back you up.

Gutrude Plus also watches the foods you never blamed and shows a pattern only when your logs line up, with the real numbers. It's a tracker, not a doctor: no diagnosis, no advice, just a clean record to take to your doctor or dietitian. Everything is stored on the iPhone with SwiftData. No account, no camera, no ads, and no health data leaves the device.

Smia (Norwegian for "the forge") is managed, private Git hosting and CI for European companies. Each company gets its own Forgejo instance on its own VM, hosted by European providers with the EU or Norway as the location, encrypted at rest, and priced per company rather than per seat. It started with a question I kept hearing in security questionnaires: where does our source code live, and who operates the platform? An EU region on a US platform answers the first half only.

The parts I build sit around an unmodified Forgejo: a Rust runner that boots a fresh Firecracker microVM for every CI job and destroys it afterwards, a Go control plane that provisions, backs up, restore-tests and offboards instances, and per-company backup keys so a customer's history opens with their key, not ours. Smia runs on Smia: its own source code and CI live on the forge it sells. Currently in the making and invite-only.

PadelIQ turns the phone-against-the-glass footage padel players already record into coaching. Film one rally, and within a minute you get a positioning heatmap for every player, stats like time at net and how often the middle was left open, and a verdict with the top three things to fix — each one citing numbers from your own clip, never generic advice.

The entire computer vision pipeline — player detection with YOLOv8 on Core ML, court homography, tracking and statistics — runs on the iPhone. Footage never leaves the device; only the measured numbers are sent to an LLM to word the verdict like a coach would. Detected weaknesses map to a library of 38 drills, and a progress view tracks how the numbers move over time.

Plask is one private profit-and-loss view for every app and site you run. Revenue comes in from Stripe, RevenueCat, App Store Connect and Google Play, traffic from GA4, and ad spend from Apple Search Ads, Meta and Google Ads. Fixed costs come out, and you see revenue, costs and profit per product and for the whole portfolio.

Every Monday, up to three Focus cards point at the products that need you, each with the numbers behind it: revenue falling while traffic holds, a product that earns well but gets no attention, ads that cost more than they bring in. Markers on releases and campaigns answer "did it work?", and an MCP server lets Claude Code or Cursor read the P&L and log ad spend.

APIDrift automatically watches third-party API changelogs for breaking changes and alerts you before your integrations break. It scrapes changelogs daily, uses AI to classify changes by type and severity, and generates step-by-step migration guides.

Get multi-channel alerts via email digests, Slack notifications, and webhooks. Track API health scores across your dependencies, export deprecation deadlines to your calendar, and stay ahead of breaking changes from Stripe, GitHub, Twilio, AWS, and 25+ other APIs.
