AI app builder pricing is hard to compare because each tool charges for something different. Bolt meters tokens. Bubble meters workload. FlutterFlow charges per seat. Adalo charges a flat fee. Here are the numbers side by side, and what each price gets you if the goal is an app on the App Store.
The short answer
All four have a free plan. The first paid plans are Bolt Pro at $25 a month (or $18 billed yearly), FlutterFlow Basic at $39 (or $29.25 billed annually), Bubble Mobile Starter at $49 (or $42 billed annually) and Adalo Builder at $65. Each reaches iPhone through a cross-platform framework: Expo, React Native, Flutter or Adalo’s own native builds. Add Apple’s 99 USD a year. According to their docs, submitting the app and handling App Review are your job in each case.
AI app builder pricing at a glance
Monthly-billing prices from each vendor’s pricing page. Where a vendor offers a discount for longer billing, it is in the last column.
| Tool | Free plan | First paid plan | Higher plans | Longer billing |
|---|---|---|---|---|
| Bolt | $0, 1M tokens a month, 300K a day | Pro, $25 a month, from 10M tokens | Teams, $30 per member a month; Enterprise, custom | Yearly saves up to 28%: Pro $18 a month ($216 a year), Teams $27 per member a month ($324 a year) |
| Bubble (Mobile) | $0, 500 AI credits, 50K workload units | Starter, $49 a month | Growth, $199; Team, $529; Enterprise, custom | Annual: $42, $169 and $449 a month |
| FlutterFlow | $0, 2 projects | Basic, $39 a month | Growth, $80 first seat + $55 second; Business, $150 first seat + $85 for seats 2 to 5 | Annual, 25% off: Basic $29.25 a month; Growth $60 first seat + $41.25 second; Business $112.50 first seat + $63.75 for seats 2 to 5 |
| Adalo | $0, 5 AI prompts a month | Builder, $65 a month ($30 first month) | Business, $200 a month | Quarterly saves 10%, yearly 20%: Builder $624 a year, Business $1,920 a year |
| AirBuild | $0 to try (currently by waitlist) | Basic, $10 a month with your own API key (currently by waitlist) | Plus, $20 a month with AI included (currently by waitlist); Ultra, $200 a month (currently by waitlist); Enterprise, $2,000 | See pricing |
Bubble sells three kinds of plan. On monthly billing, Starter is $39 for Web, $49 for Mobile and $69 for Web & Mobile; Growth is $134, $199 and $249; Team is $399, $529 and $649. Annual billing saves up to 20%: Starter is $32, $42 and $59 a month; Growth is $119, $169 and $209; Team is $349, $449 and $549.
What each tool actually charges for
Bolt: tokens. Each plan comes with a monthly token allowance. Free adds a daily limit of 300K tokens. Pro removes the daily limit, lets unused tokens roll over, and adds custom domains and removes Bolt branding. Teams adds central billing and admin controls.
Bubble: AI credits and workload units. AI credits pay for the AI agent and generation features; Bubble says they refresh on the first of the month and don’t roll over. Workload units measure the server work your app does: database operations, workflows, page loads. Web and mobile apps in one project share the same workload. Past your allowance, you buy a workload tier or pay overages, and Bubble emails you at 75% and 100%.
FlutterFlow: seats and AI requests. Basic is one editor with 50 AI requests a month. Growth and Business add editors, priced per seat, and more AI requests: 200 and 500 a month. Code download, APK download and one-click store deployment start on Basic.
Adalo: a flat fee. Adalo says it charges a flat monthly fee with no per-action metering or per-seat pricing. Builder includes 2 published apps and 5 editors; Business includes 5 published apps, 10 editors and unlimited instant updates. Extra AI credits are optional.
What it costs to reach the App Store
A low monthly price is only half the picture. The other half is what you have to do yourself between “it runs” and “it’s on the App Store”.
| Tool | iPhone app is built with | Lowest plan for the App Store | What you still do |
|---|---|---|---|
| Bolt | Expo | Bolt’s Expo guide doesn’t list a plan requirement | Download the code, install the EAS CLI, build and submit from your computer, handle review |
| Bubble | React Native | A paid mobile plan; Starter includes 5 build submissions a month | The listing, submission and review in App Store Connect |
| FlutterFlow | Flutter | Basic, for one-click store deployment | Create the App Store Connect record and API key, then add metadata and submit for review |
| Adalo | Adalo’s native builds (IPA) | Builder, $65 a month | The listing, submission and review |
| AirBuild | SwiftUI | Basic, $10 a month (currently by waitlist) | Approve the app; AirBuild prepares the listing, submits, replies to App Review and resubmits |
Every route needs an Apple Developer Program membership: 99 USD per membership year, or the local price. Bubble’s FAQ is explicit that a paid plan is needed to test with TestFlight and to publish. FlutterFlow’s deployment guide ends with you selecting Add for Review in App Store Connect. Bolt’s Expo guide lists a computer with Node.js and Git among the prerequisites.
If you plan to do these steps yourself, our App Store Connect guide covers the build, TestFlight and submission, and the App Store Review Guidelines explained covers what reviewers check.
A worked example: one iPhone app for a year
Say you build one app and keep it live for twelve months, on the lowest plan each vendor lists for store publishing, billed the cheapest way. This is the plan cost only; usage overages, backends and add-ons are extra.
| Tool and plan | Plan for a year | Plus Apple |
|---|---|---|
| Bolt Pro, yearly | $216; builds run on Expo’s EAS service, which Expo prices separately | 99 USD |
| FlutterFlow Basic, annual | $351 | 99 USD |
| Bubble Mobile Starter, annual | $504 | 99 USD |
| Adalo Builder, yearly | $624 | 99 USD |
Bolt is the cheapest plan here, then FlutterFlow, Bubble and Adalo. For Bolt, check Expo’s own pricing before you rely on its build service.
Where these builders stop for native iOS
All four tools are honest about what they make. Bubble’s native apps run on React Native. Bolt uses Expo. FlutterFlow builds with Flutter. Adalo builds its own native binaries from one design across web, iOS and Android. That is the point of each: one project, several platforms.
None of them writes SwiftUI, Apple’s own framework for iPhone apps. And according to their docs, none takes App Review off your hands: the listing, the privacy answers, the replies to reviewers and the resubmissions are yours.
Where AirBuild fits
AirBuild is an AI team for native iOS apps. Product, design and engineering agents build the app in SwiftUI. It reaches your iPhone through TestFlight, and you ask for changes in plain language. On Basic, Plus and Ultra, AirBuild prepares the App Store listing, metadata, screenshots and review notes, submits, tracks the review, replies to App Review feedback, fixes and resubmits.
- Free: $0. Try AirBuild for free.
- Basic: $10 a month. Bring your own API key; your provider bills the usage. Includes the product, design and engineering agents, standard Cloud Builds and Previews, and the full App Review workflow.
- Plus: $20 a month, with AI and cloud builds included, top AI models, and everything in Basic.
- Ultra: $200 a month, with 10× the AI usage of Plus and 10× the Cloud Builds and Previews.
- Enterprise: $2,000, with custom AI usage and cloud builds and a self-hosted backend.
Free, Basic, Plus and Ultra are currently by waitlist.
AirBuild doesn’t build Android apps. If you need both platforms from one project, the tools above are the better fit. If you already have a web app in Bolt, you can bring it to AirBuild and keep the web version where it is; the same goes for Lovable.
