iOS and Android, Properly
Navigation, gestures and components that match the platform a person is actually holding. An iOS app that behaves like an Android one feels wrong in a way users cannot name but do not forgive.
Mobile App Development Agency
An app is not finished when it runs on a simulator. It is finished when it is in the stores — which means review guidelines, privacy declarations, screenshots at the right sizes, and a developer account in your client's name rather than anyone else's. Panze builds iOS and Android apps from the design and takes them through all of it, under your brand, and hands over everything needed to ship the next version without us.
Our Process
How Panze Builds and Ships an App
Four steps, and the last one is the step agencies underestimate. Store review has rejected finished apps for reasons nobody read about until the rejection arrived.
Services
Mobile App Development Services
Panze builds native iOS apps from the design through to a signed release build. Review guidelines, privacy declarations and the submission itself are part of the job, not something handed back to you at the end.

iOS App Development
Panze builds native iOS apps from the design through to a signed release build. Review guidelines, privacy declarations and the submission itself are part of the job, not something handed back to you at the end.
Android App Development
Panze builds Android apps and ships them to Google Play, tested across the screen sizes and OS versions your client's users actually have rather than the one device the app was written on.
Cross-Platform Development
Panze builds from one codebase when that is the right answer for the budget, and says so when it is not. Some apps lose more to the compromise than they save in development.
Design to Production
Panze turns a design file into a working app, including the states a design usually leaves out: empty lists, failed requests, names twice as long as the mockup, no connection. Those decide whether an app feels finished.
API and Integration Work
Panze connects the app to whatever it has to talk to — your client's backend, payments, maps, analytics, push notifications — and makes it behave when the network does not.
App Store and Play Submission
Panze prepares the listings, screenshots, privacy declarations and signing, submits the build and deals with the rejections. The accounts stay in your client's name, so nothing depends on us afterwards.
What We Build
The Parts of an App That Decide Whether It Ships
Building the screens is the predictable half. These are the parts that make the difference between an app that demos and an app that lives on someone's phone.
APIs and Data
Talking to whatever the app runs on, including the awkward part: what the screen shows while it waits, what it shows when the request fails, and what it does with data it already had.
Offline and Poor Connections
Most apps are used on a train at some point. Deciding what works without a signal, what queues, and what syncs when it comes back is a design decision as much as a technical one, and it is made before the build rather than after a complaint.
Push, Permissions and Privacy
Notifications that are worth the interruption, permission prompts asked at the moment they make sense, and the privacy declarations both stores now require. Asking for location on first launch is how an app gets deleted on first launch.
Store Submission and Review
Listings, screenshots at every required size, age ratings, data disclosures and the review itself. We have read the guidelines so your client does not have to discover them through a rejection.
Releases and Updates
Signing, versioning, staged rollouts and crash reporting, set up so the second release is routine. An app nobody can update is an app that gets worse every month the OS moves on.
Benefits
Why Agencies Bring App Builds to Panze
Four things that matter when you have sold an app and do not build apps.
1. We Take It Through Review
Submission is part of the work, not something handed back to you as a zip file and a good luck. If the reviewer comes back with a question, we answer it.
2. Design and Build Together
Panze designed mobile products for ten years before building them, so the screens and the code come from the same team and nothing is lost explaining a design to a developer who was not there.
3. Your Client's Accounts, Not Ours
The app ships from your client's App Store and Play accounts. An app published under a contractor's account is an app the client does not fully own, and that becomes obvious at the worst moment.
4. Invisible to Your Client
We work in your tools and under your brand. White label builds stay off our portfolio permanently, in writing, before we start.
Industry Expertise
Industries We Build Mobile Apps For
Panze builds mobile apps for agencies serving fintech, healthtech, SaaS and consumer clients. Each brings its own store requirements, data rules and release expectations, and we plan for them before the build rather than at submission.
Fintech Mobile App Development
We build fintech apps with the security, auditability and store declarations financial products are held to, so app review does not become the thing that delays your launch.
Healthcare Mobile App Development
We build healthtech apps around the data rules that apply to them, with permissions and consent handled in the product rather than in a policy page nobody reads.
SaaS Mobile App Development
We build the mobile half of a SaaS platform: the same accounts, the same permissions, and the part of the product that genuinely makes sense on a phone.
E-Commerce Mobile App Development
We build commerce apps with native checkout, stored payment methods and the offline behaviour that keeps a basket intact when the signal drops.
EdTech Mobile App Development
We build learning apps with downloads, progress that survives a lost connection, and a content pipeline your client's team updates without calling us.
Social Mobile App Development
We build social apps with the feed, notification and moderation plumbing that decides whether the thing holds up once more than a few hundred people use it.
Enterprise Mobile App Development
We build internal apps with single sign-on, device policies and distribution outside the public stores where that is what the client needs.
Startup Mobile App Development
We build a first release small enough to ship and solid enough to put in front of real users, with the developer accounts and the code in the founder's name from day one.
Frequently Asked Questions
Questions About App Development
Platforms, store accounts, review, and what happens after launch.
It depends on what the app has to do. An app that is mostly screens over an API and needs to exist on both platforms is usually better served by one cross-platform codebase; an app leaning on the camera, background location or heavy animation is usually better native. We tell you which we would choose and why before the quote rather than after.
Yes, that is most of this work. Send the Figma file and we build it. Where a design is missing the states an app needs — loading, empty, offline, error, permission denied — we list those before starting, because they are otherwise found in week three.
Your client's, and we will ask for it early because getting an Apple Developer account approved can take longer than people expect. We are added to it to submit, and removed at handover. We do not publish client apps under an account of ours.
We handle it. Rejections are part of shipping rather than a sign something went wrong, and most are a privacy declaration, a missing demo login or a guideline about how something is worded. Responding and resubmitting is included — it is not extra work billed to you.
Your client. Source, signing details and store accounts transfer at handover, with documentation covering what another developer needs to ship the next version. No licence, no retainer required to keep it on the store.
Partner projects start at $1,000, though an app is rarely the smallest job. A focused single-platform release is usually weeks; both platforms with a backend, push and store submission runs two to three months. Store review itself adds days at the end that nobody controls.
