How much does a social or community app cost?

We work at a flat rate of $39 per hour, and a first release scoped like the mobile MVP on our pricing page typically lands between $4,800 and $8,500 across four to six weeks. Products with live feeds, group messaging, and real moderation tooling sit above that figure, and we quote them in phases once we know your expected user numbers.

Do we need iOS and Android on day one?

For most communities, one shared codebase in Flutter or React Native covers both stores without paying twice for the same screens. We go native only where the product leans on platform hardware or graphics performance, and we say so during scoping rather than after.

Who handles moderation, us or you?

You set the rules and we build the tools that enforce them: report queues, blocking and muting, moderator roles separate from admin, a decision log, and a takedown path you can point to if a store or regulator asks. Where a community has no staffed moderation plan, we build the queue anyway and flag the gap.

What drives our monthly server bill as the app grows?

Three things: how many feed reads and writes happen, how much photo and video you store, and how long you keep it. Text messages stay cheap. Media retention, backups, and download bandwidth are the lines that grow, so we set retention rules before launch instead of after the first invoice.

Can you take over a community app someone else started?

Yes. We audit the data model, feed queries, permissions, and moderation gaps first, then keep the parts that hold up and replace the parts that block growth. Accounts and user data stay yours, which keeps the migration path under your control.

Social & Community App Development

Social and community app development for iOS and Android: profiles, feeds, group messaging, notifications, moderation, and privacy settings.

Eggifest: Dreams Without Borders→Voteme App→SmartAIChats→

A community app looks simple in a pitch deck: profiles, a feed, a chat screen, notifications. The hard part arrives months later, when strangers post to each other faster than anyone can read. Who receives a report of abuse, and who acts on it? What does the monthly bill look like at ten thousand users instead of fifty?

We build networking and community products for iOS and Android, and we treat moderation, feed design, and data retention as decisions from the first sprint.

What a community app contains

Most products in this category share the same surface area even when the audience differs: accounts, a follow graph, a feed built from posts and photos, direct and group messaging with read state, notifications, search, reporting and blocking, a moderator interface, and privacy settings that include export and deletion.

Which you build first matters more than how many you list. Voteme took a narrow route: photo uploads, voting, credits, chat, and abuse controls, enough to give people a reason to return.

Who this is for

We build for organisations whose members need to find each other and keep returning: professional and alumni networks, member associations, parent and school groups, hobby clubs, creator communities, and charities whose participants should interact. Eggifest, the Dreams Without Borders platform, shows that pattern, with registrations at volume, an admin view for organisers, and content from many countries.

For bookings, catalogue sales, or a portal with documents and dues, see community and nonprofit portal development.

Where the project starts

A plain idea. You have a document and no code. We pick the smallest loop that can hold a community: one content type, one feed, one conversation path, plus report and block. That fits a first release of four to six weeks.

An existing codebase. The app runs, has users, and has grown awkward. We audit the data model, feed queries, notification delivery, permissions, and moderation gaps, then continue on the stack where it holds up and replace what blocks growth.

An AI or vibe-coded prototype. Screens and flows usually exist and often survive. What needs rebuilding is server side authorisation, the data model, ownership of accounts and content, moderation tooling, and the caching that keeps reads affordable, which we cover under vibe coded app rescue.

What we deliver

Accounts with Apple, Google, and email sign-in. A social graph and a feed that opens quickly on a phone connection. Direct and group messaging, with push notifications that do not wake the device for every event. Photo and video upload with compression. A moderator console with report queues, suspension, blocking, and a log of decisions. Privacy settings, export, and deletion that match your published policy. An admin backend, plus submissions to both stores.

How an engagement runs

Discovery takes about a week and produces a scoped first release, a data model, and a named person on your side who owns moderation policy. The build runs in short cycles with a testable build at the end of each. We soft launch to an invited group, because load behaviour and report volume are guesswork until real people use the app. Retention, message volume, and report volume then decide what phase two contains.

Moderation decides whether the community survives

A feed without moderation fills with spam, scams, and harassment, and the members you wanted leave before the trend is obvious.

Report categories that match what actually happens, response targets you can staff, symmetric blocking, rate limits on new accounts, and the ability to switch off comments or direct messages for one member or for everyone. Moderators need a role separate from admin, so a volunteer can act on content without reaching payouts or user records. Every action leaves a note of what was reported, what was decided, and by whom. Some markets also expect a documented notice and takedown path for illegal content, which makes the log evidence as well as a fairness record.

How feeds scale

The cost of a feed comes down to one choice per content type.

One option writes a copy of each post into every follower's feed at publish time. Reads stay fast, because the feed is already assembled. The price sits on the write side: a post from an account with five thousand followers creates five thousand rows, and popular accounts become the expensive ones.

The other option stores the post once and assembles a feed when someone opens the app, reading from the accounts they follow. Writes stay cheap and storage stays flat. Each open costs more work, and it gets slow for members who follow hundreds of active accounts, so it needs pagination, caching, and ranking.

Most products use both: publish time fan out for ordinary accounts, open time assembly for the few with huge followings, chosen per content type, since a photo post and a short text update do not cost the same to distribute.

What message storage costs

A direct message between two people is stored once per conversation, so text itself is cheap. Copies, bytes, and time drive the rest, and a group message stored once with read state per member multiplies work rather than storage. Copying it per member makes read receipts easy to query and turns a busy group into the largest table in your database. We keep one copy plus per member state.

Attachments dominate. Photos and video weigh far more than text, and each file is stored, backed up, replicated, and downloaded again on every view. Download bandwidth often costs more than storage itself.

Retention decides whether those numbers grow forever. Dormant conversations, media in groups nobody reads, and abandoned accounts keep costing money. Decide early what ages out, what is archived, and what is deleted when a member closes an account. Presence, typing indicators, and delivery attempts are transient signals, and storing them as history buys nothing.

What it costs

We quote at the flat rate of $39 per hour, or as a fixed scope once requirements are clear. A first community release usually lands in the order of the typical mobile MVP on the pricing page: $4,800 to $8,500 across four to six weeks for roughly twenty to twenty five screens with a cloud backend, authentication, and store submissions. The same published pricing lists monthly capacity plans from $2,699 for continuous delivery.

Scope drivers make more sense in weeks than in invented totals. One feed with one content type adds little. Group messaging, presence, and per member read state add several weeks and a permanent running cost. A moderator console with appeals and an audit log is a phase of its own, and search, video transcoding, maps, and AI moderation services carry recurring fees outside development.

Proof

Voteme is a cross-platform social app in Xamarin with photo uploads, community voting, credits, real time chat, and user blocking and reporting. It shows the engagement loop and the safety controls shipping in one release.

Eggifest is the Dreams Without Borders platform, a WordPress site for a children's charity active in 27 countries, with more than 10,000 Dream Capsules distributed. It covers the operations side of a community: intake at volume, an admin view for organisers, and multilingual content run by a small team.

SmartAIChats is a conversational platform on React, Next.js, Node.js, and OpenAI, handling live visitor chat, lead capture, and support triage. It shows the messaging layer we bring to in app chat: conversation state, escalation to a human, and an AI layer given one defined job.
