How long does it take to build a mobile app in Istanbul?

It depends on scope. In GG Tech Teknoloji's estimation model the typical timeline band for mobile app development is 6–16 weeks; the Cost Drivers page explains how to read the bands. Ask other companies for their own timelines.

How much does it cost to build a mobile app in Istanbul?

GG Tech Teknoloji's published prices (excluding VAT): MVP $8,000–16,000 (6–10 weeks), standard iOS + Android app $17,000–32,000 (10–16 weeks), enterprise app with integrations $35,000–70,000. Clients in Turkey are quoted and invoiced in TRY. The final budget is set in a written quote after an initial call. Ask the other companies for their own prices.

Is this list a ranking?

No. The companies are in alphabetical order and the order is not a quality rating. The list is published by GG Tech Teknoloji, which is itself on it; that is why we gave no scores, took no payment and set out the criteria in the Methodology section.

What does a Clutch rating show?

Clutch verifies a review by talking to the client who wrote it. With few reviews a single review moves the rating a lot, so look at the number of reviews and the published references alongside the rating.

Mobile App Development Companies in Istanbul (2026)

Eleven companies building mobile apps in Istanbul, in alphabetical order: headquarters, founding year, technologies, published references and Clutch reviews. The list is not a ranking; its publisher, GG Tech Teknoloji, is included and disclosed as such.

In short: below are 11 companies that build mobile apps in Istanbul, in alphabetical order. The list is not a ranking. Each company's details come from its own website or its Clutch profile and were checked in October 2026; sources are at the end.

Conflict of interest: this list is published by GG Tech Teknoloji, and GG Tech Teknoloji is one of the companies on it. That is why we did not score or rank the companies; we described ourselves by the same criteria, at the same length and only with information published on our own website.

Methodology

Criteria: an Istanbul office stated on the company's own website or Clutch profile, mobile app development offered as a service on its own website, a live website, and published work or references that can be checked by name.
For companies with a Clutch profile, the rating and number of verified reviews are copied from Clutch as shown; where no profile was found the cell says "Not found".
Review date: October 2026. Details change over time; check each company's own website for current information.
No company paid to be listed and we paid no one; there is no arrangement with any listed company for this list.
The list is not a ranking: companies are in alphabetical order and the order is not a quality rating. The list is not exhaustive either.

Six questions to ask when choosing a mobile app company

Native, Flutter or React Native? Does the company recommend an approach with its reasoning, or use the same tool for every project?
Does it have a published reference it can name? An anonymous "we built an app for a bank" cannot be checked.
Are the backend, admin panel and integrations built by the same team? Most of a mobile app's work sits behind the screen.
Does it have verified client reviews? Platforms such as Clutch verify a review by talking to the client who wrote it.
Is it open about timeline and cost bands? Before a proposal you should get an answer to "how many weeks, which team".
Are store release and post-launch maintenance in scope?
