Service · App check
A second look at your app.
For live apps, prototypes and applications that are stuck. We look at the product from the user's perspective and at the technology behind it – and tell you honestly where you stand.
- For apps, web apps and prototypes
- A description is enough – a link is optional
- Never send login credentials
Typical reasons
When an app check makes sense.
Users drop out
Registrations, bookings or purchases are not completed – and nobody knows exactly why.
Users drop out
- Find drop-off points in the flow
- Review sign-up, checkout & onboarding
- Uncover unclear copy & buttons
- Concrete improvements instead of guesses
Development is stuck
Every change takes long, errors keep coming back, the original team is no longer available.
Development is stuck
- Causes of recurring bugs
- Assess structure & dependencies
- What is legacy, what is solid?
- A plan to ship faster again
Before the next stage
You're planning a relaunch, new features or more users and want a solid basis first.
Before the next stage
- Can the base carry more users?
- What must happen before the relaunch?
- Spot risks early
- Order for the next expansion
Taking over a project
You've taken over an app and want to know what you're actually dealing with.
Taking over a project
- What is really inside the app?
- Strengths, weaknesses & open issues
- Where is documentation missing?
- A clear basis for decisions
What we look at
Four perspectives on your app.
Product clarity
Is it clear what the app does and for whom? Do start page, onboarding and store entry convey that?
Product clarity
- Home page & first impression
- Onboarding & entry
- Store listing, copy & screenshots
- Is the value clear within 5 seconds?
Usability & accessibility
Where do users stumble? Are central flows short, comprehensible and usable for everyone?
Usability & accessibility
- Core flows step by step
- Forms, error messages, navigation
- Contrast, font sizes, keyboard
- Check against WCAG 2.2 AA
Technical baseline
As far as visible from the outside or from the material provided: performance, stability, structure and security indicators.
Technical baseline
- Loading times & Core Web Vitals
- Stability & error patterns
- Visible security indicators
- Structure, where material is available
Further development
Which steps would bring the most – and in what order?
Further development
- Quick wins first
- Medium-term rework
- Effort vs. value per measure
- Recommended order
Process
How the app check works.
Request
You describe your app and your concern. A link to the app or store entry helps but is optional.
Please never send login credentials via the form.
Personal review
We look at the app ourselves. Links are stored only as a reference and opened manually – not fetched automatically.
If we need test access, we agree on a secure way.
Follow-up questions
If needed we ask about goals, users and known problems.
Only if needed.
Feedback
You receive an individual assessment with findings and prioritised recommendations.
What you do with it is entirely up to you.
Result
What you get.
Findings
What works well and where the biggest stumbling blocks are.
Findings
- What works well – and should stay
- The biggest stumbling blocks
- Backed by concrete places in the app
Prioritisation
Which measures bring the most value for the effort.
Prioritisation
- Measures sorted by impact
- Rough effort estimate
- What now, what later?
Recommended next steps
From quick improvements to a sensible further development plan.
Recommended next steps
- Quick improvements
- A sensible expansion plan
- Optional: implementation with us
What the app check is
- A professional assessment of product, usability and technical baseline
- Honest feedback with concrete recommendations
- A basis for decisions about further development
What the app check is not
- An assessment of market value, purchase price or saleability
- A binding company valuation
- A full security audit or penetration test
- A legal review, e.g. of data protection or store guidelines
