iPhone
Your short-form coach, in one chat. Instagram, TikTok and YouTube Shorts.
Every day Booster does the research you used to do by scrolling: it studies reels that are working right now from accounts you want to post like, breaks one down, and tells you exactly what to film and say. You film it with the script on screen, and Booster writes the caption and posts it to Instagram, TikTok and YouTube Shorts in one tap.
HOW A SESSION GOES
1. Open Booster. Today’s session is already prepared.
2. Watch the reel it picked and read the breakdown: the hook, the beats, the shot list, why it works.
3. Tap “Film with the script.” The lines scroll on screen while you record.
4. Send the take. Booster captions it and publishes everywhere you’ve connected.
5. Ask “How am I growing?” any time and get your real numbers with one recommendation.
TALK TO IT LIKE A PERSON
“Different reel.” “Make it shorter.” “Change the hook.” “Remind me at 6.” “Here’s my plan for the week.” Booster adjusts, remembers, and keeps the session moving. Paste any Instagram link and it tells you what to steal from it.
BUILT FOR PEOPLE WHO POST, NOT PLAN
• One thread a day, already researched
• Reels first: hooks, beats, shot lists, scripts in your voice
• Captions written for you, posted when you say so
• One reel, three platforms: Instagram, TikTok and YouTube Shorts
• Straight talk about which platform is actually growing you
• Accounts you admire become your daily inspiration
• Your growth, explained in plain language
WHAT IT NEVER DOES
Booster never posts, likes, follows, or comments without you. It studies public posts only and never uses your logins to browse.
Your first session is free. Keep going with a subscription: $12.99 a month after a 3-day free trial, or $4.99 a week. Cancel any time in your Apple ID settings.
