A developer on a monthly plan. One request at a time, most back in about 2 days.

Skip the quote for every small job. Send requests for your app or website, and they are worked on one at a time: bug fixes, features, Stripe and AI work, store-build updates. Code arrives as pull requests you merge. Pause or cancel anytime.

Billed monthly in advance. Work starts within 1 business day of payment and repo access. Pause or cancel by email before your next billing date.

No call needed. Questions go to contact@app369.com; we reply by email, usually within one business day.

This fits when

  • You have a steady list of small changes and fixes, not one big project
  • Quoting every job takes longer than the job
  • Your app was built by someone who has moved on
  • You want Stripe, Firebase, Supabase or AI work done without hiring

Monthly Dev Subscription

Development on a monthly plan instead of a quote per job: send requests, one is worked on at a time, and most come back in about 2 business days. Mobile, web, Stripe, Firebase, Supabase and AI work on apps you already have. Pause or cancel anytime.

Starter

$1,495/mo
Billed monthly, pause or cancel anytime

One app or website. Bug fixes, small features, UI and copy changes, Stripe, Firebase or Supabase fixes, and dependency and store-build updates. One request at a time.

Studio

$3,995/mo
Billed monthly, pause or cancel anytime

Up to 3 apps or websites. Everything in Starter, plus new features, screens, AI features and integrations. One request at a time.

How it works

  • Send requests by email and say which comes first
  • One request is worked on at a time; most come back in about 2 business days
  • Bigger requests are split into pieces, each aimed at about 2 business days

How it works

  1. Step 1

    Subscribe and send repo access

    Pick Starter or Studio, then reply to the Stripe receipt with repo access and your first request.

  2. Step 2

    Send requests in order

    Add requests by email whenever you like and say which comes first. One is worked on at a time.

  3. Step 3

    Review pull requests

    Most requests come back in about 2 business days as a pull request with a note on what changed and how it was tested. Bigger ones are split into pieces.

Questions before you pay

What is a request?
One change you can describe in a few sentences: fix this bug, add this field, connect this webhook. Bigger work is split into pieces that each aim to come back in about 2 business days. That is typical, not a guarantee.
What is the difference between Starter and Studio?
Studio is not faster: both work on one request at a time. Studio covers up to 3 apps or websites and larger features, new screens, AI features and integrations, split into several pieces over the month. Choose Starter if you have one app and mostly small changes.
How does pausing work?
Email before your next billing date and the subscription is paused; nothing is charged while paused, and you can resume or cancel later.
How much work fits in a month?
There is no cap on queued requests. Work is one request at a time, so how many finish in a month depends on their size. It is one developer, and planned time off is announced in advance.
Do I need calls?
No. Requests and updates are by email. Live calls are available at $100 per 15 minutes.
Is this the same as ongoing maintenance?
No. Ongoing maintenance covers upkeep: security patches, monitoring and emergency fixes. The subscription is for the changes you ask for, one at a time.
Do I need a call before I pay?
No. The scope, price and delivery time are on this page, and everything happens in writing. If you want to talk live, calls cost $100 per 15 minutes, paid upfront.
Who owns what you deliver?
You do. The code, videos and files delivered under this offer belong to you once paid.
