Short answer: one Google Account can manage several YouTube channels, and the YouTube app on iPhone switches between them. To post Shorts to many channels on a schedule, you can either use the YouTube Data API — which is quota-limited and, for unverified projects, uploads as private — or drive the real YouTube app on real iPhones, which is what Farmero does.
Several channels on one iPhone
- A single Google Account can manage multiple channels through Brand Accounts (YouTube Help).
- The YouTube app on iPhone can hold several Google Accounts and switch between them and their channels.
- Keep each channel to one niche. Mixing unrelated channels on one Google Account is an organisational choice, not a technical limit.
API or the app?
| YouTube Data API | The real app on an iPhone | |
|---|---|---|
| Daily volume | Google's default: 100 videos.insert calls per day per project (Google) |
No API quota |
| Unverified projects | Uploads are restricted to private until the project passes an audit | Not applicable |
| Setup | A Google Cloud project, OAuth per channel | Sign in on the phone |
| What the platform sees | An API upload | The app on a phone |
| Confirmation | API response | Depends on the tool |
For a handful of channels and a verified project, the API is fine. For many channels, the real app avoids the audit and quota work.
Scheduling Shorts from real iPhones with Farmero
- Sign the channels in on the phone's YouTube app.
- Add them as accounts in Farmero.
- Queue the clip, pick the channels and times.
- Farmero delivers the clip over the cable, opens YouTube, checks it is on the right channel, composes and publishes — then checks the channel for the new Short before it marks the post posted. A post it could not see go live is recorded as uncertain and never retried automatically.
Among iPhone-based posting tools we have checked, YouTube is the platform most often missing: as of 17 September 2026, tame lists Instagram and TikTok, and Clout Uploader is TikTok only.
Reusing clips across channels
The same clip on TikTok, Instagram and YouTube is ordinary cross-posting. The same clip on several YouTube channels is where caution belongs: YouTube's Partner Program excludes channels built on reused content from monetisation. Farmero warns you when a clip is about to go to the same platform twice. More: posting the same video to multiple accounts.

FAQ
How long can a YouTube Short be?
Up to three minutes, in a square or vertical format.
Can I schedule Shorts in the YouTube app itself?
YouTube Studio supports scheduling for uploads, but it does not rotate a clip across many channels for you. That is the job of the tool driving the phone.
How many channels can one iPhone post to with Farmero?
Farmero plans are sized at eight accounts per iPhone, and a YouTube channel counts as an account.
Does Farmero use the YouTube API?
No. It uses the YouTube app on your own iPhone.
