I build Sendhour, so read this with that in mind. This list is for apps, whether you run one or slideshows for many client apps. Facts come from each vendor's own pages. Prices checked November 11, 2026 (Viraloop and Reels Farm on November 8).
What an app slideshow needs
App slideshows that work tend to share a shape. One study of app slideshows on Indie Hackers found the same few formats across unrelated niches: tips and mistakes, problem and fix, roundups, and "which would you choose".
- A hook slide. The first slide decides whether anyone swipes. Copy the pattern of a hook that worked, not its words.
- Pictures that fit the niche. Real photos for most consumer niches; app screens only where they answer the hook.
- The app as the payoff. It shows up after the hook as the answer, not as an ad on slide one.
So ask each tool where it gets the format, where it gets the pictures, and whether it posts to TikTok as a photo post on every account you run.

Sendhour
Sendhour starts from a post that already worked. Its viral library lists public TikTok posts and YouTube Shorts doing far more views than their account usually gets, grouped by niche. You can also watch rival accounts, or paste a TikTok link. The studio copies the post's structure and hook, never its footage, and makes a slideshow of 3 to 10 slides from real photos (1 credit for the whole slideshow), AI images (1 credit a slide) and your own photos (free). It can copy the original's text style or use yours, and you can change one slide's words or photo without redoing the rest. Then it posts to TikTok, YouTube, Instagram, Threads, Bluesky, X and LinkedIn through each network's official API. On TikTok, slideshows go out as photo carousels, or to your TikTok drafts if you want to add a sound first.
Give Sendhour your App Store or Google Play link and it saves your app's screenshots; every slideshow can then show one in a phone frame on its last slide, free. With autopilot on, it also drafts a post when the listing shows a new release.
An AI agent can do all of this through the API, MCP server and CLI, including reading a slideshow and editing one slide. I run about 15 TikTok accounts for my own apps from it, mostly photo slideshows plus some videos. My best posts have reached around 50,000 views.
Price Starter is $29 a month ($23 billed yearly) for 5 accounts and 200 AI credits. Growth is $49 for 15 accounts. See pricing.
Good to know No free plan or trial. It doesn't turn ratings milestones into posts. It doesn't post to Facebook.
Fits Solo developers and teams who want slideshows modelled on what's working now, on many accounts and networks.
Spreadcast
Spreadcast is built only for App Store apps. You paste your App Store link and it builds a brand kit from your icon, colors and screenshots, then makes posts with your real app screens in an iPhone frame or frameless. It never uses stock photos, and you can upload up to 10 of your own. It checks your listing daily, so a new version or a ratings milestone becomes a post, and it can post on its own at 9 am or wait for your approval. TikTok slideshows go out as photo posts. It has an MCP server you connect with a sign-in.
Price Free for 3 posts to download, with a small mark and no publishing. Pro is $29 a month ($290 a year) for 1 app, 10 social accounts and 40 photos a month. Studio is $79 for 5 apps, 50 accounts and 3 seats. Pro and Studio have a 7-day full refund.
Good to know Google Play apps aren't supported yet. There's no library of viral posts; ideas come from your listing. Its slides are 4:5, one set for every network.
Fits iOS developers who want steady posts about their own app with almost no work.
Viraloop
Viraloop turns your website into short videos and slideshows and posts them on its own. It has a trending library tagged by niche with a remix button, 20 formats, one of them called Green Screen Mobile App, and it takes your own uploads. It posts to TikTok, Instagram Reels, YouTube Shorts and Facebook, can send TikTok posts to drafts, and has analytics.
Price Free for 10 posts a month, no card. Starter is $19 a month for 5 accounts and 100 credits; Growth $49 for 20 accounts.
Good to know I couldn't confirm on its site that slideshows go to TikTok as native photo posts.
Fits Founders who want to try the whole loop for free before paying for anything.
Reels Farm
Reels Farm (reelsfarm.com) makes slideshows, UGC-style images and short videos, with a library of over 3,000 prompts. Paste a public TikTok slideshow link and it rebuilds it. It posts to TikTok and YouTube, adds Instagram and Facebook on the $47 plan, and every plan has an MCP server, SDK and CLI.
Price Starter is $19 a month for 200 credits and 2 TikTok or YouTube accounts. Creator is $47 for 10 accounts. The 5-day trial doesn't include publishing.
Good to know No viral library; you bring the link. It isn't ReelFarm (reel.farm), a different slideshow tool.
Fits Founders on a small budget who already know which slideshows they want to copy.
Relay
Relay (relaystudio.ai) makes TikTok content for brands. Paste your website or App Store link and it makes a month of slideshows and videos in your brand's voice, based on formats getting views in your niche. You swipe to approve or pass, and each approved post lands in your TikTok inbox as a draft on its day, where you tap Post. On its top plan, a network of creators can post your drafts from their own accounts.
Price Starter is $49 a month ($25 the first month) for 40 posts made and 20 sent. Growth is $99 for 120 made and 60 sent, with up to 3 people. Scale is $249. The trial is 1 day with a card on file.
Good to know TikTok only, and nothing posts without you tapping Post in TikTok. Its site doesn't say where the pictures come from, and it lists no API.
Fits A brand or app with no content team that wants a month of drafts made for it and will approve each one.
SupaSlides
SupaSlides makes animated carousels. Paste your website and it picks up your colors, fonts and voice, then writes and designs the slides. You add your own images once and it places them on the right slides. It exports PNG, animated MP4 and PDF for LinkedIn, and every plan includes an MCP server.
Price Free for 3 carousels a month with a watermark. Pro is $19 a month for 3 brands and 20 carousels; Studio $39 for 10 brands and 80 carousels.
Good to know It auto-posts to Instagram, Facebook Pages and X today. TikTok posting is coming; its own blog says that for now you upload the slides yourself. I found no library of viral posts.
Fits Founders whose carousels are mostly for Instagram and LinkedIn, and who want them on-brand and animated.
Where each competitor is the better choice
- Spreadcast if your app is on the App Store and you want steady posts about the app itself with no work, including ratings milestones turned into posts and a choice to let them go out on their own. It gives 10 accounts for $29 against Sendhour's 5, and it has a free plan.
- Viraloop if you want to start for free, or need Facebook.
- Reels Farm if you already have the slideshows you want to copy and $19 is the budget.
- Relay if nobody on your team will make posts and you'd rather approve a month of drafts. Its creator network is something none of the others offer.
- SupaSlides if you want animated carousels or LinkedIn PDFs in your brand's fonts and colors.
Slideshows for several accounts or client apps
One account is a test. Five per app, or ten client apps, is a production line, and here the tools differ most.
- Accounts per dollar. At $29, Spreadcast gives 10 accounts for one app and Sendhour gives 5. At $49, Sendhour gives 15; Viraloop gives 20. Relay lists no account limit; it caps posts sent.
- Apps and brands. Spreadcast Studio covers 5 apps and 50 accounts for $79; SupaSlides Studio 10 brands for $39. Sendhour's Agency plan has 50 accounts for $99; each client workspace has its own plan, and one person can switch between them.
- People. Spreadcast Studio has 3 seats and Relay Growth up to 3 people. Sendhour includes unlimited teammates on every plan, each with a role (Owner, Can post or Drafts only), so a junior or a client can propose slideshows without publishing them.
How to make your first app slideshow in 15 minutes
- Find a breakout. Search your niche on TikTok and open a few profiles. Pick a slideshow with several times the views that account usually gets.
- Write down its shape. For example: "Slide 1 is a complaint people relate to, slides 2 to 5 are tips, slide 6 shows the app as the last tip."
- Write your slides. Same number of slides, same hook pattern, your topic.
- Pick the pictures. Real photos that match the mood of the original, and one or two app screens after the hook.
- Post it as a photo post and send it to drafts if you want to add a trending sound in the TikTok app.
- Make two more with different hooks before you judge the format.
A mistake to avoid: judging a format on views alone. One person on r/AppStoreOptimization read 74 posts about TikTok slideshows for apps and found almost none had a real download number. Note the day's installs next to each post so you know which slideshows sell the app, not just which get swiped.
Questions
Is there a free AI slideshow maker for apps?
Yes, with limits. Viraloop's free plan makes 10 posts a month and posts them. Spreadcast's free plan makes 3 posts from your App Store listing for you to download, with a small mark and no publishing. SupaSlides' free plan makes 3 carousels a month with a watermark. Sendhour has no free plan or trial.
Should an app slideshow use real photos or AI images?
Use whatever looks like the posts already working in your niche. For lifestyle, fitness, food and travel apps that usually means real photos of real moments. AI images are fine for objects and scenes that are hard to photograph. Your own app screens belong after the hook, where they answer it. Sendhour can put one of your store screenshots in a phone frame on the last slide.
Do these tools post slideshows to TikTok as photo posts?
Sendhour, Spreadcast and Relay say they post slideshows to TikTok as photo posts. Relay always sends them to your TikTok inbox as drafts; Sendhour can post directly or send to drafts. SupaSlides' own blog says TikTok publishing is still in beta and you upload the slides yourself. I couldn't confirm the format for Viraloop or Reels Farm on their sites.
How many slides should an app slideshow have?
Copy the slide count of the post you're remaking; it's part of what made it work. Sendhour makes 3 to 10 slides, and SupaSlides caps a deck at 10.
