Turn a photo or an idea into a post that sounds like you. Zup helps you write captions, edit photos, preview your post and share when you're ready. • Start with a Moment or a Thought. Choose photos, take a picture or tell Zup what's on your mind. • Find your tone. Generate an AI caption, try a different tone and set your preferences for length, emojis and hashtags. • Make photos your own. Crop, add text, try filters or use optional AI photo editing, with controls to undo changes and restore the original. • Preview before sharing. Check your photos and edit your caption in a familiar platform layout before you post. • Share across your socials. Prepare posts for Instagram, TikTok, X, LinkedIn and Facebook. Publish to supported connected accounts or use iPhone's share sheet. • Plan now, post later. Schedule LinkedIn and X posts using suggested times or your own date and time. Manage or cancel scheduled posts in Your voice. You choose what to publish and where it goes. Scheduled posts can publish at the time you confirm, even when the app is closed. Suggested posting times do not predict reach or engagement. AI generation asks permission before sending content to Zup's server and the configured AI service. Unscheduled drafts stay on your device. Scheduled captions and photos are stored encrypted on Zup's server until cancellation or a final publishing result. Hosted AI and connected social features require an internet connection. Direct publishing depends on account eligibility and service permissions. Instagram requires a supported professional account; Facebook publishing is for Pages. Text-only drafts support X, LinkedIn and Facebook. Apple on-device captioning availability depends on your iPhone, language and settings. ## Key features - Multi-photo selection - Platform-aware caption drafts - On-device captioning - Customizable voice profile - Direct publishing to X and LinkedIn - Native iOS share sheet ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Zup Support — Small Thanks | $1.99 | one-time | | Zup Support — Warm Thanks | $4.99 | one-time | | Zup Support — Big Thanks | $9.99 | one-time | ## Is Zup safe?

The social platform bar now uses native Liquid Glass to soften the photos and text behind it, keeping your controls easier to see in light and dark mode. ### 1.26 — 2026-10-19 Meet Fenn, your new companion while Zup writes captions and edits photos. Enjoy a clearer Home screen with photos that fill their cards, warm matte-gold details, and refined caption and platform controls. We also improved the launch experience and made small fixes throughout the app. ### 1.25 — 2026-10-18 A smoother Zup, from launch to posting. Switch between light and dark appearance in Your voice. Native navigation keeps the header controls steady as pages slide, and Post opens the right sharing choices. We also refined Instagram handoff, stopped imported photos from being saved as duplicates, and added press-and-hold controls to mark a platform as posted—or unmark it. Sharing now includes a caption preview. We also refined platform controls, LinkedIn caption expansion, Back buttons and account-disconnection confirmations. Connect and Disconnect now share the same native glass styling. Caption controls stay clear and visible while Zup is writing or polishing. ### 1.24 — 2026-10-14 A cleaner first look with new onboarding photos, a simple Tone picker, and clearer favorite-platform buttons. We refined the empty Home screen and photo-edit loading experience, and improved reminders that open your saved draft on the suggested platform. ### 1.23 — 2026-10-11 A cleaner start: try one simple tone picker and choose your favorite platform for Compose. This update improves social photo layouts, glass caption controls, and Your voice navigation. Photos taken in Zup save to Photos, and connected account names are remembered on your device. Writing a text post keeps your Gist saved, LinkedIn text drafts stay fully expanded, and post notifications open the matching draft. Proofreading offers improvements only when changes are suggested. ## Apps similar to Zup | App | Rating | Price | Category | | --- | --- | --- | --- | | [Opinion.](https://appshunter.io/ios/app/opinion/id6752958138) | 5.0 (11) | Free | Social Networking | | [fiammo: write with friends](https://appshunter.io/ios/app/fiammo-write-with-friends/id6791766677) | 5.0 (5) | Free | Social Networking | | [Xuman](https://appshunter.io/ios/app/xuman/id6751751941) | 4.2 (10) | Free | Social Networking | | [SocialLoop](https://appshunter.io/ios/app/socialloop/id6742368050) | 4.9 (27) | Free | Social Networking | | [Huddle Social](https://appshunter.io/ios/app/huddle-social/id6449878483) | 4.3 (15) | Free | Social Networking | | [Campus Dating: Find Love](https://appshunter.io/ios/app/campus-dating-find-love/id6745430703) | 2.1 (16) | Free | Social Networking | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
