How to Check Istanbul Studio References
A reference is a person who will tell you what it was like to ship. A logo wall is advertising. When you hire in Istanbul you still need the same conversation you would have in any city, plus timezone and entity checks. The hiring checklist is a sibling: what to check when hiring. This page is how to run the reference itself. Croncode LLC is in Albuquerque. Engineering is in Istanbul. We are not croncodetech.com.
Check Istanbul studio references by speaking to a person who shipped, confirming who owned the Apple account, and looking at a live listing. A slide of logos is not a reference.
Who should you ask to speak with?
The product owner who sat in the demos, not a salesperson who joined after launch. Ask for a name and a year. Ask whether that person still has the App Store listing. Account ownership: who owns the account. If they cannot show a listing, ask for a TestFlight story you can verify another way. Live consumer proof we can show is ours: YourStyle, Numira, Spylie, Luviport.
Our names are public: Goktug Unver, Yusufhan Sokur, Ozgur Ismet Ozkan. Do not invent a biography for Ozgur. A short public profile is enough.
Which questions survive a polite call?
- Who submitted the binary, and whose Apple org was it?
- What slipped after version one, and who stayed?
- How did they handle a crash on the first job? Crash questions.
- Did the sprint demo show a build or a deck? Sprint demo.
- Was the support inbox alive? Support email.
Vendor models: studio vs freelancer vs agency. iOS selection: choose an iOS studio.
When is a reference useless?
| Signal | Treat as weak | Treat as useful |
|---|---|---|
| No overlap hour mentioned | Yes | They name a clock |
| “They were cheap” | Yes | They name ownership |
| Cannot say who wrote Turkish | Yes if you need TR | They name a reviewer |
| NDA blocks every fact | Often | They can still describe process |
Localization: onboarding localization. Commercial shape: fixed price vs retainer. Security: security questions.
How do you verify without being rude?
Open the App Store listing they cited. Read recent reviews as a team habit you will also use on your own app: reviews. Check that the legal name on the invoice matches the entity they want you to sign. Identity hygiene: Croncode vs croncodetech. Shipping story: how we ship.
If they only offer a marketing site, that can still be real work. It is not store proof. When a site is enough.
What mistakes waste the reference week?
- Asking for a best-app ranking: nobody honest should give you one.
- Accepting a WhatsApp voice note as the only paper trail: you need a contract later.
- Skipping the not-now conversation: feature creep will repeat. Feature creep.
- Confusing a freelancer bench with a studio: write the model.
Quote packet: what to send. Hire: hire. Custom: custom software. Contact: contact. Journal: /en/journel/. Home: /en/.
What can Croncode offer as proof without fake case studies?
Public store pages, this Journal, and named people. We will not invent client logos. We will not write Ozgur a novel. What we build: what Croncode builds. What we refuse: will not build. Team index: meet the team.
If you want process proof, sit a sprint demo and watch for a binary: sprint demo. A reference call that only praises communication is incomplete. Ask what slipped. Ask who stayed after launch. Ask whether the not-now list was real. Polite studios can still leave you with a personal Apple ID. That is the question that pays.
Frequently asked questions
Do I need three references?
One honest shipper beats three polite blurbs. Ask for depth, not a count.
What if the studio is young?
Then their own store apps and a clear entity matter more. Youth is not a sin. A logo wall of work they did not do is.
Can I ask about rates on the reference call?
Ask about surprises in change orders. Exact rates belong in your quote, not in someone else’s NDA.
Should I fly to Istanbul to check them?
A visit can help a large program. It does not replace account ownership or a live listing.
How do I start with Croncode after references?
Send the job to contact or the homepage with the packet in the quote article.
