Common ground
What do Develak apps have in common?
Different audiences, same standards. These principles apply to every app in the catalogue.
Up to 44 languages
Our apps are localized with Xcode String Catalogs, so people read them in their own language, from Arabic to Vietnamese, with right-to-left layouts where needed.
Native Swift & SwiftUI
Written in Swift on Apple’s own frameworks. No cross-platform layer, no web view dressed up as an app.
Private by design
No account, no ads, no third-party trackers. Your data stays on your device and in your own iCloud.
iPhone, iPad and Mac
Every iPhone app also runs on iPad, and our 2 developer tools are native Mac apps.
Free to download
Try any app for free. Optional Pro features are billed by Apple and can be cancelled at any time.
FAQ
Questions about our apps
How many apps has Develak published?
Develak has published 34 apps on the App Store since 2025: 9 health and fitness apps, sports logs, hobby journals, productivity tools and 2 Mac apps for developers. All of them are listed on this page.
Are Develak apps free?
Yes, every Develak app is free to download. Most offer optional in-app purchases or subscriptions for Pro features. Payments are handled by Apple, and you can cancel a subscription at any time in your Apple Account settings.
Do I need an account to use a Develak app?
No. None of our apps asks you to sign up or log in. Your data is stored on your device and, if you turn on sync, in your own private iCloud account, which Develak cannot access.
Which devices do Develak apps support?
Our iPhone apps also run on iPad and need a recent version of iOS (iOS 17 or later for most of them). Xlocalize and Appviary are native Mac apps. Each app page lists its exact requirements.
How do I get help with one of your apps?
Every app has its own support page with answers to common questions and a contact form. You can also write to contact@develak.com: we read every message and reply personally.
Can Develak build an app like these for my business?
Yes. The studio behind these 34 apps designs and builds custom iPhone, iPad and Mac apps for clients worldwide, in English and French, from the first prototype to the App Store launch, localization and maintenance.
