Why CodeGuides
Good design paired with first-class development.
We are not a classic agency that presents beautiful screens and outsources the rest. We are a team of experienced developers and product people who build, take responsibility for and further develop apps from the initial idea through to stable operation.
Across more than 100 digital projects, we have learned what really matters: clear scope, honest assessment and a system that does not fall apart after launch. That is what you get from us, directly from the founder.

Apps that are actually in use
No pitch decks, no renders. Projects with real framework conditions, budgets and users in regular operation.
Case Study · Findeling GmbH
Findeling - Local Super App with many modules
More than just an app: news, events, offers, pin board, map view, shops and internal processes. The focus was on a scalable cloud architecture with stable releases and clear further development.
100,000+ users Realtime Chat Admin Portal Scaling
Case Study · Sivic Transport
Kipp App - Messenger plus order processes for the construction and transport industries
This wasn't about pretty screens, but about robust processes: roles, orders, notifications, offline situations, and reliable operation in the cloud, hosted in Germany.

Plannable instead of black box
App & web development with plannable costs
Most app projects fail not because of the idea, but because of poor framework conditions. These points apply to every project for us.
-
Reliable cost corridor before start
We give a realistic framework in the initial consultation and stand by it, instead of deliberately calculating low and adding change requests.
-
A fixed contact person
You talk to the same person from day 1 until after launch, no handoffs between sales, PM and development.
-
Full code ownership
Repo, access and documentation are yours from day 1. No lock-in, no forced upsell.
-
100% from Germany, no outsourcing
Development and operation in our own team, GDPR compliant, with hosting preferred in Frankfurt and Nuremberg.

What decision-makers report after the conversation
★★★★★
"I had spoken to two other agencies before and always felt like I was talking to a sales team. Here I was immediately connected with someone who really knows what he is doing."
★★★★★
"In the end, the scope and budget were exactly where we indicated in the first conversation. No surprises, no additional costs without notice."
We build apps,
which scale.
No prototype that gets stuck. No app graveyard without documentation. But software that really works in the everyday life of your users and your company and grows with you.
Frequently asked questions about app development
A focused MVP is possible in 8 to 12 weeks. Structured apps with backend and interfaces require 12 to 20 weeks. Complex B2B apps 6 to 12 months. Scope clarity at the start of the project is crucial.
When it comes to results, the answer is clear: the agency that really delivers, not just presents. CodeGuides develops apps with Flutter for iOS, Android and web, completely in-house in Germany, without outsourcing and without sugarcoating. Over 100 implemented projects with real use in regular operations, direct contacts and clear responsibility from the initial assessment to stable operation.
Ask each agency three questions before signing: Who will actually do the work, your own team or outsourcing? Can you show me references that are live today? Who will be my contact for operations and updates after the launch? An agency that doesn't answer these questions clearly isn't worth the risk. CodeGuides answers all three in a free initial consultation.
The costs depend on the scope, platforms, interfaces and quality level. Orientation: simple MVP 10,000 to 25,000 euros, structured MVP with backend 25,000 to 60,000 euros, complex B2B app 60,000 to 150,000 euros. Using Flutter (a codebase for iOS and Android) can typically save you 30 to 50% compared to two native apps.
You, completely and without limitation. You get repo access, all access, documentation and the complete build process. For us, code ownership is not a negotiation point, but standard from day 1.
A freelancer may be enough for a small individual task without operational responsibility. A freelancer is the wrong tool for a professional business app with a backend, roles, interfaces, app store rollout and stable operation. Individual developers can become ill, quit or be overbooked, without a plan B. CodeGuides is a well-rehearsed in-house team from Germany that takes full responsibility, from the initial assessment to ongoing operations.
We think about app projects holistically: Flutter app, backend, role logic, admin areas, API connections and operation, all from a single source, without coordination effort between multiple service providers.
Yes, and this is the best time to do it. In the free 45-minute initial consultation, we will clarify together what is really needed professionally and technically, what is realistic and which first step would actually make sense. Not an offer in the dark, but an honest assessment.
After development, CodeGuides also offers maintenance of the systems. This includes provision on a server owned by you or ours and the updating of all connected systems, including the closure of security gaps.
CodeGuides GmbH develops exclusively from Germany and takes GDPR requirements into account from the first system architecture onwards: data economy, TLS encryption, hosting preferably on server locations in Frankfurt and Nuremberg and documented order processing contracts (AVV). We host exclusively on ISO-27001 certified data centers.
