Sendhour vs Spreadcast: which TikTok tool fits app marketing?

I build Sendhour, so weigh this with that in mind. Spreadcast is the closest tool to Sendhour that is built only for apps, and I've tried to say plainly where it's the better pick. Spreadcast's facts come from its own pages. Prices checked November 12, 2026.

What each tool does

Spreadcast calls itself social media automation for App Store apps. You paste your App Store link once and it builds a brand kit from your icon, colors and screenshots. It checks the listing every day, so a new version or a ratings milestone becomes a post in your brand, with your real app screens in an iPhone frame. It never uses stock photos. You can also ask for one of twelve kinds of post, such as a testimonial, a comparison or a how-to, or upload your own pictures and video and let it write the captions.

Sendhour starts from posts that already worked for someone else. Its viral library finds public TikToks and YouTube Shorts doing far more views than their account usually gets. The studio makes your version of one, copying the structure and the hook but never the footage. Then it schedules the post to TikTok, YouTube, Instagram, Threads, Bluesky, X and LinkedIn through each network's official API, across as many accounts as your plan allows.

So the two answer different questions. Spreadcast answers "what do I post about my app this week?" Sendhour answers "which format is working in my niche right now, and how do I make my own?"

Finding what to post

Spreadcast's ideas come from your app: what changed in the listing, a milestone, or a post type you pick. You'll never run out of true things to say, and every post looks like your brand. It works best on people who already know your app or your category.

Sendhour's ideas come from the feed. The library ranks posts by how far they beat their own account's usual views, so a post with 40,000 views on an account that normally gets 2,000 ranks above one with 200,000 on an account that always gets that much. That points at formats that work for small accounts, which is what a new app account is. You can also watch up to 5 rival TikTok accounts or YouTube channels on Starter (80 on Scale) and see each one's posts that beat its usual views, with a button to make your version.

One founder on r/appdev put the difference well after a single TikTok crossed a million views: "You don't need a viral app. You need a viral video about your app." A release announcement rarely reaches people who have never heard of you. A format that is already travelling in your niche can, with the app shown as the answer near the end.

Making the post

Spreadcast designs every post from your brand kit: your colors, fonts and app screens. Paid plans include photos made for your posts (40 a month on Pro, 150 on Studio), and its carousel maker makes 3 to 8 slides. Slides are 4:5, so one design works on TikTok, Instagram, LinkedIn and Facebook. You can upload your own video, and it writes a caption for each network.

Sendhour's studio makes slideshows of 3 to 10 slides from real photos, AI images and your own photos, and short videos cut from real clips with a voiceover and AI video. It copies the original's text style or uses yours, and you can change one slide's words or photo without redoing the rest. Real photos matter for lifestyle, fitness, food and travel apps, where the posts that work show real moments, not screens.

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. That puts your real app on the payoff slide, after the hook has done its job. Spreadcast puts your screens at the center of most posts.

I run about 15 TikTok accounts for my own apps from Sendhour, mostly photo slideshows plus some videos. My best posts have reached around 50,000 views.

Posting, autopilot and networks

Both post TikTok slideshows as photo posts through TikTok's official API. Spreadcast's go out without music, and you add a sound in TikTok. Sendhour can post directly or send the post to your TikTok drafts so you can add a sound first.

Spreadcast lists 11 networks it posts to, including Facebook, Mastodon, Telegram and Discord. Sendhour posts to 7: TikTok, YouTube, Instagram, Threads, Bluesky, X and LinkedIn. If you need Facebook, Spreadcast has it and Sendhour doesn't.

Spreadcast's autopilot has two modes. Approve First waits for one tap on each post. Full Autopilot lets posts go out on their own at 9 am your time, from the first day. Sendhour's autopilot prepares 1 to 3 drafts each morning from what's working in your niche; when your store listing shows a new release, the first one is about that release. At first nothing goes out until you open a draft, render it and schedule it. Once an account's last 10 drafts went out without edits, Sendhour offers to post them for that account. Then each post is scheduled at least 2 hours ahead, with an email that has a one-use cancel link.

Accounts, apps and teams

Spreadcast counts apps and accounts. Pro is 1 app and 10 social accounts; Studio is 5 apps, 50 accounts and 3 seats, and each app keeps its own brand, accounts and calendar.

Sendhour counts accounts only: 5 on Starter, 15 on Growth, 50 on Agency and 100 on Scale. Each workspace has one brand profile, so a second app with its own brand gets its own workspace and plan, and one person can switch between workspaces. Teammates are unlimited on every plan, each with a role: Owner, Can post, or Drafts only, for a junior or a client who should suggest posts without publishing them.

For an agency, the split is this. With 3 to 5 apps that each need their own brand, or 16 to 50 accounts, and no more than 3 people, Spreadcast Studio at $79 is simpler and cheaper. With more people, more than 50 accounts, or clients on Google Play, Sendhour fits better.

Agent access

Both connect to Claude and ChatGPT as an MCP server with a sign-in. Spreadcast's agent can make drafts on the free plan and also publish on paid plans. I found no REST API or command line tool on its pages.

Sendhour has an API, an MCP server and a CLI covering posting, drafts, the viral library, watched rivals, analytics and credits. You pick read only, drafts only or full posting when an agent connects, and Sendhour checks it on every call.

Pricing compared

Both start at $29 a month. Billed yearly, Spreadcast Pro is $290 and Sendhour Starter is $279.

• Up to 5 accounts: the same monthly; billed yearly, Sendhour is $11 less.
• 6 to 10 accounts for one app: Spreadcast is cheaper, $29 against Sendhour's $49.
• 11 to 15 accounts: Sendhour is cheaper, $49 against Spreadcast Studio's $79.
• 16 to 50 accounts: Spreadcast Studio is $79 for up to 5 apps and 3 seats; Sendhour Agency is $99 with unlimited teammates.
• More than 50 accounts: Spreadcast lists no bigger plan. Sendhour Scale is $199 for 100.

Spreadcast also sells two one-off options: a Post Pack of 10 posts for $19 that never expires, and a 30-Day Pass with everything in Pro for $39. Pro and Studio have a full refund within 7 days. Sendhour plans include AI credits (200, 500, 1,200, 3,000 a month by plan), and extra credits from $15 for 100 never expire.

Where Spreadcast is better, and who should pick it

• A free plan. No card and no time limit, plus pay-once options for a launch month.
• Posts about your app with no effort. New versions and ratings milestones turn into branded posts on their own. Sendhour drafts a post for a new release but not for milestones.
• Posting on its own from day one. Full Autopilot doesn't make you earn it first.
• More accounts for one app at $29. 10 against Sendhour's 5.
• Several apps under one plan. Studio keeps 5 apps apart, each with its own brand.
• More networks. 11, including Facebook.

An iOS developer with one app who wants it to keep showing up on their channels without thinking about it should pick Spreadcast. So should a small studio with up to 5 App Store apps that wants each one's updates posted on brand.

How to choose

1. Check your store. Google Play only, or both stores: Sendhour. App Store only: either.
2. Decide what the posts are about. News about your app: Spreadcast. Formats that are reaching new people in your niche, with the app as the payoff: Sendhour.
3. Count accounts for the next three months. 6 to 10 for one app favors Spreadcast; 11 to 15, or more than 50, favors Sendhour.
4. Count people. More than 3 on the team: Sendhour.
5. Decide who drives. If an agent or a script will run the posting, check for an API and permission levels.

A mistake to avoid: judging either tool by views alone. A post can travel and sell nothing. Note the day's installs next to each post for a few weeks, so you know which posts bring downloads, then let autopilot do more of those.

Questions

Does Spreadcast work for Android apps?

Not yet. Spreadcast reads only Apple App Store listings, and its FAQ says Google Play is next. Sendhour reads an App Store or a Google Play link.

Is there a free way to try either?

Spreadcast has a free plan with no card and no time limit: one app, drafts for new versions and ratings milestones, and 3 posts to download with a small mark. It doesn't publish on the free plan. Sendhour has no free plan or trial, but its viral TikTok finder is free with no sign-in: paste an App Store link and it shows posts beating their account's usual views in your app's category.

Do both post TikTok slideshows as photo posts?

Yes. Spreadcast's own page says its slideshows go to TikTok as photo posts without music, and you add a sound in TikTok. Sendhour posts photo carousels directly, or sends them to your TikTok drafts so you can add a sound before it goes live.

Can an AI agent run either one?

Both have an MCP server that Claude and ChatGPT connect to with a sign-in. Spreadcast's lets an agent make drafts on the free plan and publish on paid plans. Sendhour also has a REST API and a CLI, and you pick one of 3 permission levels when an agent connects: read only, drafts only or full posting.

Which is cheaper for 15 TikTok accounts?

Sendhour. Its Growth plan covers 15 accounts for $49 a month. Spreadcast Pro stops at 10 accounts, so 15 needs Studio at $79. For 6 to 10 accounts for one app, Spreadcast is cheaper: $29 against $49.
