Best for: Nordic and healthcare companies that want a small senior team for a MedTech, data or custom platform project.

Verdict. Choose Polar Night Software for Nordic or healthcare work with a small senior team. Ask for financials newer than 2024 first, because that year closed with a loss.

Who is not in the top 5, and why

What they charge

On Clutch, the companies in this table most often declare 50 to 99 USD an hour. The rate is what the agency bills; the developer on your project is paid less than half of it.

For comparison, my own rate is 36 to 54 USD an hour (45 USD base, pricing). The cost estimator shows what a project like yours costs with and without coding agents.

25-49 USD/h 1
50-99 USD/h 4

150-199 USD/h 0
Rates declared on Clutch, 5 companies with an office in the city.

Check any agency yourself in 10 minutes

  1. Ask for apps they shipped and still maintain, with the App Store link. Native iOS costs more than cross-platform, so it pays off for apps that lean on the device.
  2. Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
  3. Read the last financial statement in the Financial Documents Repository (free, by KRS number): revenue, profit or loss, and whether it was filed on time.
  4. Check the VAT white list: active, and the name matches the contract.
  5. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
  6. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
  7. Ask who exactly will work on your project, and check those people on LinkedIn.

Questions

What are the best iOS and Swift software houses in Łódź in 2027?

By the score on this page: 1. FiveDotTwelve (80), 2. goodylabs (58), 3. TDCM (57), 4. Inovatica (53), 5. Polar Night Software (44). The score adds up transparency in the court register, client reviews on Clutch, profit and stability in the latest filing, specialization and current hiring. The full table shows every company in the data set.

How much do iOS and Swift agencies in Łódź charge?

Most companies in this table declare 50 to 99 USD an hour on Clutch. My own rate as a senior engineer working with AI agents is 36 to 54 USD an hour.

How do you know a company does iOS and Swift?

From at least one of three sources: the service, industry and framework shares on the Clutch profile, the skills in open roles on JustJoin.it, or the Wrocław company catalog. Companies with two or three sources score higher on specialization. The software house finder shows the same tags for every company.

Did any company pay to be on this list?

No. There are no paid placements and no affiliate links. The only business interest is mine: I sell senior engineering as the alternative to an agency.

Can I get my company added or corrected?

Yes. Write to ciunkos@gmail.com with the KRS number and the correction.

How this ranking was made

  • 1,424 companies in the data set
  • 1,101 with KRS records
  • 1,003 with a financial statement
  • 7,436 Clutch listing records
  • 849 employee review profiles on GoWork

Sources: Clutch profiles and listings, KRS records, available financial statements from rejestr.io and the Financial Documents Repository, GoWork reviews, JustJoin.it and No Fluff Jobs listings, and the Wrocław company catalog. Coverage varies by company; dates and links accompany the available records. The 0 to 100 score combines six axes: transparency, client reputation, stability, specialization, activity and hiring in the last 90 days. Paid Clutch placements do not increase the score.

Disclosures

  • Until November 2026 I work at Sanddev (Wrocław) as the founding engineer of its Sandtime product. Sanddev appears in the full table with the same score as everyone else and no editorial favor.
  • No agency pays for a position, there are no affiliate links. If any of that changes, the disclosure changes first.
  • My business interest is on every page: I sell senior engineering with AI agents as the alternative to hiring an agency.
  • Written with AI (Claude) from the data set. Every number in the editorial text is checked automatically against the company record or the research notes, source links and dates accompany the available company records.
