Timelines at a glance
| What you’re building | Solo dev | Agency | With AI |
|---|---|---|---|
| Simple app (few screens, local data) | 2–4 weeks | 4–8 weeks | A weekend |
| MVP (one real feature + backend) | 6–10 weeks | 2–4 months | 1–2 weeks |
| Full product (auth, payments, sync) | 3–6 months | 4–9 months | 3–6 weeks |
These are working ranges, not promises — the variance inside each cell is huge, driven almost entirely by scope discipline and how many times you change your mind.
Where the time actually goes
The feature you’re excited about is usually the fastest part. Here’s the real breakdown of a typical first app:
- Setup & scaffolding (10–20%): project config, navigation, theming, the native toolchain. Pure overhead — and exactly what AI generators erase.
- Core features (25%): the screens and logic that are the point of the app. Genuinely productive time.
- Auth, data & backend (20%): login, storage, sync — the plumbing every app needs and nobody sees.
- Polish & edge cases (25%): the last 20% that takes 80% of the time — loading states, errors, empty states, device quirks.
- Testing & submission (10–15%): real-device testing, store assets, review, and the near-guaranteed resubmit.
What AI compresses — and what it doesn’t
An AI app builder collapses the two most tedious buckets — setup/scaffolding and the first pass of core features — from weeks into minutes. You describe the app and get a working React Native app with navigation, screens, and data already wired, previewable on your phone.
What it does not compress is honest: App Store review still takes 1–3 days, real user testing takes as long as it takes, and deciding whatto build is still on you. So the realistic AI timeline is “working app in a day, shippable app in a week or two” — not “done in an hour.” Anyone claiming the latter is selling a prototype, not a product.
The biggest speed-up is second-order: because iteration is minutes instead of days, you find out what’s wrong with your idea far sooner — which is the part that actually saves months.
The fastest realistic path in 2026
- Cut scope to one core feature. This decision saves more time than any tool.
- Generate a working version with AI and preview it on a real device the same day.
- Show five real users, iterate by prompting — days, not sprints.
- Add auth and payments once the core has proven it’s worth it.
- Budget a week for polish, store assets, and the review cycle.
