How to Use Blastr

Overview

The flow is simple, every time:

1. Connect your socials — link your YouTube channel, Instagram + Facebook page, and TikTok account to a workspace. You only do this once per workspace.
2. Drop in your video or photo — drag it onto the home screen (or tap to browse). You can queue several at once.
3. Review the thumbnail — pick a frame for YouTube, or check your photo's crop.
4. Set up your blast — write captions, toggle platforms on or off, and tune per-platform options.
5. Blast it — post right now, or schedule it for later. BLASTR shows live progress for every platform.

Connect Your Socials

Head to the CONNECTIONS tab (or hit Connect Socials from the home screen). Each platform connects with its own official login — BLASTR never sees your passwords.

Your First Blast

1. Drop your file. Drag a video (MP4/MOV) or photo (JPG/PNG/WebP) onto the drop zone on the home screen. BLASTR starts uploading and optimizing in the background while you keep working.
2. Thumbnail. Scrub through your video and pick the frame you want as the YouTube thumbnail. (Instagram, TikTok, and Facebook choose their own previews.)
3. Settings. Write your caption, toggle which platforms this post goes to, and open each platform's options card to fine-tune (collaborators, location, privacy, and more).
4. Schedule. Choose BLAST IT to post immediately, or pick a date and time. You can even set a different time per platform.
5. Walk away. The moment you hit BLAST IT you're back on the home screen, and the post publishes in the background — a progress card above your Library shows each platform lighting up with a live %, then a green ✓ as it finishes. Finished posts land in your Library with direct links.

Captions

Write one caption and it goes everywhere — or tap a platform tab above the caption box to give any platform its own custom caption (different hashtags for TikTok vs. YouTube, for example).

• The main caption is used for any platform without a custom one.
• YouTube uses the first line as the title.
• Not ready to post? Save to Drafts keeps everything — captions, settings, the video itself — so you can finish later from the Library.

Caption Handles

Your drummer is @drummerdude on Instagram but @drummerdude_official on TikTok — so which one goes in the caption? With Caption Handles, both: define a person once and BLASTR swaps in the right handle for each platform automatically.

1. On the Settings page, hit the @ HANDLES button (next to Save as Defaults).
2. Add a person — give them a name and fill in their handle for each platform they're on. Save.
3. In any caption, type their name in brackets: @[Alex]. When the blast goes out, each platform gets that person's correct handle.

• Works in captions and in the YouTube title/description too.
• If someone has no handle for a platform, their plain name is used there instead.
• Names aren't case-sensitive — @[alex] works fine.
• Handles are saved per workspace, so each band has its own roster. Up to 30 people per workspace.

Platform Settings

On the Settings page, each platform you've toggled on shows its own options card.

Video Length Limits

Each platform has its own rule for how long a video can be. BLASTR checks your clip before you blast and shows a yellow ⚠️ warning right on the review, settings, and blast screens if it's too long for a platform you've selected — so nothing fails as a surprise. The platforms that can take it always still go out.

Photo Blasts

Photos work just like videos — drop a JPG, PNG, or WebP and blast it to Instagram, Facebook, and TikTok. (YouTube doesn't support photo posts, so it's automatically switched off.)

Aspect ratios & the crop tool

Platforms want photos in 1:1 (square), 4:5 (portrait), or 9:16 (story/full-screen). On the review step, BLASTR checks your photo:

• ✅ A green chip means your ratio is good to go.
• ⚠️ An amber warning means platforms may crop it unpredictably — hit CROP to fix it.

The crop tool lets you pick a ratio preset, then drag to position and pinch/scroll to zoom. Rule-of-thirds guides help you line up the shot, and BLASTR never stretches your photo beyond its real resolution.

Scheduling

On the Blast Options page, pick a date and time and BLASTR holds the post until then — no need to keep the app open. Scheduled posts appear in your Library's Scheduled tab and move to Published automatically when they go live.

Per-platform timing

Want the YouTube Short at noon but the TikTok at 6 pm? Turn on the Per-platform toggle in the time picker, then click each platform's tab to give it its own time. Any platform without a custom time uses the main one.

Good to know

• YouTube & Facebook schedule natively on their own servers.
• Instagram & TikTok have no built-in scheduling, so BLASTR's servers hold your video and publish it at the exact time you chose — no need to be online.

Changed your mind?

Open the post's 3-dot menu in your Library's Scheduled tab to reschedule it. One catch: because YouTube and Facebook hold their copies on their own servers, rescheduling in BLASTR moves the Instagram and TikTok times — for YouTube or Facebook, change the time in YouTube Studio or your Facebook Page.

Preferred Schedule

Always post at the same times — say 9 am, noon, and 6 pm? Save those once and let BLASTR slot your queue in automatically.

1. On the Blast Options page, open 🕐 PREFERRED SCHEDULE and add your go-to posting times. Save.
2. Queue up your videos as usual — no need to set times on each one.
3. Hit ⚡ AUTO-FILL and every unscheduled video in your queue gets assigned, in order, to your next open time slots.

• Auto-fill skips slots that are already taken — by posts you've scheduled before or by other videos in the queue — and rolls into the following days as needed.
• Past times today are skipped automatically; the first open future slot goes first.
• Saved times are per workspace, so each act can keep its own posting rhythm.
• You can still adjust any video's time by hand after auto-filling.

Library & Drafts

Everything you've blasted lives in the Library on the home screen, in three tabs:

Use the 3-dot menu on any card to edit, retry a failed platform, reschedule, or delete.

Add a platform to a post you already blasted

Forgot to include TikTok? No need to re-post everything (and double-post the rest). Open the post from your Library, toggle the missing platform on, set its options, and hit Save Changes — BLASTR blasts only the new platform and leaves the already-published ones untouched. The post stays as one card with all its links.

Cloud backup — retry from anywhere

After a successful blast, BLASTR keeps a backup of your video in the cloud — how long depends on your plan: Cadet 3 days, Voyager 5 days, Interstellar 7 days. Look for the green "Backed up · N days left to retry" chip on the card. While it's there, you can retry a failed platform or add a new one from any device, even if the original file was on another computer. Once the backup expires, you'd need to re-upload the file to post it somewhere new.

Notifications

Since blasts run in the background — and scheduled posts can go live hours after you've closed the app — BLASTR can ping you the moment a blast publishes, so you never have to keep checking.

1. Open Profile → Account Settings and find the Notifications block.
2. Hit Turn On and allow notifications when your browser asks.
3. Send yourself a test to confirm it's working.

You'll get one notification per blast when it's done — ✅ published, ⚠️ partially published (some platforms worked, some didn't), or ❌ failed — covering immediate blasts and scheduled ones that publish later.

Save as Defaults

Dialing in the same settings for every post gets old. Once a video's settings are exactly how you like them — platform toggles, YouTube visibility, Instagram share options, TikTok privacy, all of it — hit SAVE AS DEFAULTS on the Settings page.

• Every new upload in that workspace starts pre-filled with your defaults.
• Defaults are per-workspace, so each band or brand can have its own.
• Captions and locations are deliberately not saved — those change with every post.

Workspaces & Teams

Workspaces

A workspace is a complete, separate identity: its own connected socials, its own library, drafts, and defaults. Manage one artist on Free or Starter, or up to 10 workspaces on Pro — perfect for managers running multiple acts.

• Switch workspaces from the bar under the top nav — everything on screen switches with it.
• Manage them from Profile → Manage Workspaces: rename, switch, create, or delete.

Teams Pro

Invite people into a single workspace so a bandmate, editor, or manager can post for that act — and only that act.

1. Open Profile → Manage Workspaces and click the workspace to expand it.
2. Under Team, enter their email and hit INVITE MEMBER. They get an email link to join.
3. Set their access: Read Only (view) or Make Edits (upload and blast).

Members see only the workspace they were invited to, and their blasts there don't count against their own plan's limits.

Plans & Billing

Upgrade, downgrade, or manage your card any time from Profile → Billing. Payments are handled securely by Stripe.
