adb shell input tap is not automation — four reasons it fails on the second phone
A coordinate records where something used to be, not what it is. Four ways that difference bites once you own more than one handset, and what to do instead.
Your automation will break on a Tuesday. Design for it.
A routine drives an interface somebody else can change without telling you, so the design goal is not preventing breakage — it is shortening the gap between the break and the moment you find out.
How to automate an iPhone
What it actually takes to drive a real iPhone from a Mac — WebDriverAgent, Xcode signing, and the wall you hit the moment you try to do it for someone else.
The seven-day wall: why your iPhone automation stops working every week
A free Apple ID signs WebDriverAgent for exactly seven days. What breaks on day eight, why it looks like a dead cable, and how to tell the two apart in ten seconds.
n8n can't reach your phone. Here's the handoff.
Why no HTTP node will ever tap a screen, what people pay a middleman to avoid noticing, and the exact webhook contract that hands the last mile to a handset you own.
One phone per client: the boring alternative to faking a device
Six clients, six accounts, and the answer the internet gives you — followed by the reason NOISEY declines it, itemised honestly including what it costs.
scrcpy with twenty phones: what breaks between one and many
One phone is a solved problem. Twenty is a different program — the handshake races, the socket ordering, the coordinate space and the failure that looks like a healthy tile.
What each social posting API will actually let you do in 2026
Instagram, LinkedIn and TikTok gate publishing on three different things — account type, legal entity and audit — and which one stops you depends on whose account you are posting to.
Why your scheduling tool can’t post to TikTok the way you expect
TikTok’s Content Posting API will accept your video, return 200 to every call, and publish it where nobody can see it. The audit gate, whose quota you are spending, and the honest cost of the other route.
From a folder to a posted video, without touching an API
The whole loop, drawn honestly: how a file gets into a folder, what decides when it posts, what the phone actually does, and every guard between there and posting the same video twice.
