9 best apps for TikTok and Reels creators on iPhone Duo
Nine apps for making short-form video on iPhone Duo: editors, captions, hooks, thumbnails and recording, picked for TikTok, Reels and Shorts.
Short-form video is all about speed: a hook in the first second, tight cuts and captions people can read with the sound off. A foldable phone helps because you can film with the rear cameras while watching yourself on the outer display. Here are nine apps that make TikTok, Reels and YouTube Shorts faster to produce.
1. CapCut: best for trend templates
CapCut is still the go-to editor for TikTok: templates, effects, auto captions and beat sync. It is free, with a Pro subscription for some features.
2. PromptSlate Studio: best for nailing the hook in one take
Our app. Most short-form videos fail in the first three seconds. PromptSlate Studio puts a tight script, hook first, beside the camera, so you deliver it straight to the lens instead of glancing at notes. On the Duo you can use the rear cameras and read from the outer display. Use Creator Assist to cut a script down to 30 seconds on device. It is in final development for iOS 27.1 and will be a $9.99 one-time purchase.

3. Instagram Edits: best for Reels
Edits is free with no watermark, records up to 10 minutes and publishes straight to Reels. If Instagram is your main platform, start here.
4. Captions: best for animated subtitles
Captions auto-transcribes and styles subtitles, and can also correct eye contact. Its main features need a subscription.
5. TikTok Studio: best for analytics and drafts
TikTok's free Studio app collects analytics, comments and drafts for creator accounts in one place.
6. Canva: best for covers and text overlays
Canva has short-form cover templates and quick graphics. It is free, with a Pro subscription.
7. VN Video Editor: best for a free alternative
VN is a capable free editor with no watermark, useful if you want to avoid CapCut.
8. Blackmagic Camera: best for a cleaner image
Lock exposure and white balance so your clips match from cut to cut. It is free.
9. Adobe Premiere: best for longer cuts reused as clips
Edit the long version in Premiere, then export vertical clips from it. It is free.
The bottom line
Record the hook with PromptSlate Studio, cut it in CapCut or Edits, and add captions. That workflow produces a polished short in minutes.
