Overview

App testing and security checks, in plain words

Mobile app testing services find what is broken before the stores and your customers do. We test that features work, that the app runs on the devices people use, that it stays fast, and that new changes have not broken old features. We also run basic security checks against common mobile risks.

We test apps we built and apps other teams built. You get a ranked list of problems with steps to reproduce each.

One limit up front: the security part is basic. It is not a formal penetration test or a certification, and we do not issue compliance reports.

Who it is for

  • Owners about to launch
  • Teams getting bad reviews for crashes they cannot reproduce
  • Businesses that update often and worry about breaking things
  • Founders wanting a plain security check

What you get

  • A ranked list of bugs, each with steps to reproduce
  • Device and system-version results
  • Performance notes on start-up, speed and battery use
  • A repeatable regression checklist and a short list of basic security findings

Signs you need it

Problems this work fixes

If one of these sounds familiar, you are in the right place.

  1. Bugs reach customers firstIf your first testers are your users, they find the problems and write reviews about them. A planned test pass catches most earlier and cheaper.
  2. It works on our phones, not theirsScreen sizes, makers and system versions behave differently. Testing a deliberate spread of real devices shows where the app breaks.
  3. Every update breaks something oldA new feature can quietly damage a working one. Regression testing re-checks the key paths each release.
  4. Nobody has checked the security basicsApps often store data carelessly or trust the wrong things. A basic review catches common mistakes early.

What is included

What we do, part by part

  • 01

    Functional testing

    We use every feature as a user would. That includes bad input, lost connection and interrupted payments.

  • 02

    Device and version testing

    We test real iOS and Android phones across sizes and system versions. We match your users as closely as we can.

  • 03

    Performance testing

    We check start-up time, responsiveness, memory and battery use. Slow screens get flagged.

  • 04

    Regression checklist

    We write a checklist of your key journeys so each release is re-checked quickly. Some of it can be automated where that pays off.

  • 05

    Basic security checks

    We look for data in plain text, weak sign-in handling, insecure network calls and exposed keys. It is a basic review, not a formal test.

  • 06

    Clear written report

    Findings come ranked, with reproduction steps and suggested fixes. We can walk your developers through it on a call.

How it works

How the work runs

  1. Agree what to test

    We list your key features, platforms and devices. Scope and fixed price go in writing.

  2. Run the test passes

    We test on real devices and run performance checks. We also review for basic security mistakes.

  3. Report and rank

    You get findings in order of importance. We answer questions within 12 hours.

  4. Re-test the fixes

    After your developers fix the issues, we re-test them. We then update the regression checklist.

Straight answer: Our security checks are basic. They are not a formal penetration test, an audit or a certification, and we do not issue compliance reports. If a regulator or customer needs one, use a specialist security firm.

Quick answers

About cost and timing

The things people ask right after they see a price.

It depends on the number of features, platforms and devices, and whether you want a one-off pass or ongoing testing. We scope it on a call and fix the price in writing before we start. Flexible on scope. Firm on price.

It depends on the size of the app and the devices involved, so we give a date after the call rather than a guess. A small app takes much less time than one with payments and many screens. You know the timeline before you agree.

How we contract

Clear terms, before you spend anything

The commercial side in plain words. The full wording is in our terms, and your proposal sets the details.

  1. A written proposal comes firstScope, deliverables, milestones, price and timeline, in writing. Work starts when you accept it.
  2. The price does not moveOnce agreed, the number in the proposal is the number on the invoice. Changes to scope are quoted as a written change request and only built once you approve them.
  3. You pay by milestoneProjects are paid in milestones set in your proposal. No project is billed in full upfront. Invoices are payable within 14 days unless your agreement says otherwise.
  4. You own the workCode, designs and accounts are registered to your company from day one. We keep our own pre-existing tools and methods.
  5. No lock-inEither side can end a project with written notice, and you pay for the work done up to then. Retainers run month to month with 30 days written notice.
  6. 30 days of fixes after launchDefects in what we delivered are fixed for 30 days after launch. New features and third-party changes are quoted separately.

App testing and security checks FAQ

Questions about app testing and security checks

The things people ask before they book. If yours is missing, ask us on a call or on WhatsApp.

Still have a question?

Thirty minutes with us usually answers everything, including whether we are the right fit.

Yes. We test your app from the outside, like a user, and report what we find. If we need to read code for the basic security review, we ask for access under your control. The report says plainly what we could not check.

No. We run basic checks against common mobile risks, such as insecure storage and exposed keys. It is not a formal penetration test or certification, and we do not issue compliance reports. For those, you need a specialist security firm.

We agree a list with you based on who uses your app, covering common phone makers, screen sizes and system versions. We use real phones for the important paths and emulators for the rest. The report states which devices were covered.

Partly. Repeating the same key journeys before every release is where automation pays off. Some things, such as how a screen feels, still need a person. We tell you which checks are worth automating so you do not pay for the wrong ones.

We can, as a separate agreed piece of work with its own fixed price. Many clients prefer their own developers fix issues while we re-test. If we built the app, fixes in the 30 days after launch are already covered.
