Your app is probably not failing for the reason you think

Ratings are falling. Revenue has slowed down. Crashes keep appearing after releases. Every month the team ships fixes, improvements, and new features — yet the underlying problem remains unresolved.

Customers

  • More support complaints
  • Checkout and SDK  friction
  • Friction in key user flows
  • More negative reviews
  • Lower customer satisfaction

Revenue

  • Conversion rates declining
  • Subscription cancellations
  • Reduced retention
  • LTV under pressure
  • Organic growth slowing down

Engineering

  • Growing technical debt
  • Slower releases
  • More production incidents
  • Rising maintenance effort
  • Teams afraid to touch critical code

Delivery

  • Roadmaps constantly changing
  • Priorities debated every sprint
  • Decisions made without clear data
  • Recovery plans based on assumptions
  • Budget spent without confidence in outcomes

Signs your app needs an audit now

The symptoms are visible. The root cause usually isn't.

1

APP STORE & PLAY STORE RATINGS KEEP DROPPING

App Store or Play Store rating dropped by 0.5+ stars  in 90 days. Reviews flag specific feature failures, not just price complaints.

2

NEW RELEASES AREN'T MOVING THE NUMBERS

Revenue, retention, or conversion rates are no longer improving. New releases aren't producing meaningful results.

3

IOS OR ANDROID CRITICAL FLOW STOPPED WORKING

An iOS or Android update introduced issues with checkout, authentication, subscriptions, notifications, or another critical flow.

4

THE SAME BUGS and crushes KEEP COMING BACK

Issues reappear release after release. Fixes don't stay fixed. Engineering effort is increasingly spent on recurring problems.

5

REVENUE ISN'T FOLLOWING THE EFFORT

Engineering effort keeps increasing, while revenue growth, customer retention, and product performance remain flat.

6

YOU KEEP LOSING USERS

Users abandon onboarding, drop off before completing key actions, fail to return, or stop engaging with the product over time.

From first call to written report

01

Qualification call (30 min)

We review your app, key integrations, and technical complexity to define the right audit scope. You get a fixed price before anything starts. No commitment required.

02

NDA + access granted

After signing an NDA, you provide read-only access to your repository, App Store / Play Store consoles, and crash analytics.

03

Audit

We work independently across all three streams. No daily check-ins required from your side.

04

Written report

You receive a complete report with findings, prioritized recommendations, and effort estimates in ranges. It can be used by your team, another vendor, or incorporated into your planning and budgeting process at any time.

05

Readout call (60 min)

We walk through the findings, answer your questions, explain the rationale behind each recommendation, and discuss priorities and next steps.

06

Your decision

The report is yours to use however you choose. Continue with Gilzor or use it internally. If you engage us within 30 days, 100% of the audit fee is credited toward the Discovery Sprint.

Why Gilzor

This isn't surface-level consulting. We've spent years taking over mobile apps with declining ratings, stalled growth, and growing technical debt. This audit brings that experience into a structured recovery assessment.

What we bring

Experience

7+ years building iOS and Android products

Takeovers

Specialized in taking over inherited and legacy codebases

Industry Exposure

Experience across AI, e-commerce, subscription, and mobile products

Team Capacity

11 senior mobile engineers + 3 QA on the bench

mobile-first

Mobile-first expertise across iOS, Android, React Native, and Flutter

What makes us different

Speed

Fast delivery without compromising quality.

Clarity

Prioritized findings focused on what matters most.

Real-World Delivery

We build mobile products, not just advise on them.

Flexibility

Findings are vendor-neutral - you're not locked into working with us.

Partnership

Long-term thinking, not fixed-scope vendor relationships.

What our clients
frequently ask

How long does the audit take?

3 working days for a Quick Audit (single platform, fewer than 4 integrations). 8–10 working days for a Full Audit (cross-platform, complex integrations, larger codebase). Tier confirmed on the qualification call.

What access do you need?

Read-only access to the source repo, App Store and/or Play Store consoles, and crash analytics. NDA is signed before access is granted. If access isn’t available within the standard timeline, we’ll tell you on the call before any agreement is signed.l.

What happens after the audit?

You decide. If you want Gilzor to execute the fixes, we start with a 2-week Discovery Sprint (fixed price) — named team, sprint-level estimates, agreed monthly cap. Audit fee credited 100% if you sign within 30 days. If you don’t proceed — no pressure, no follow-up.

Can we take the report to a different vendor?

Yes. The report is yours. We don’t lock findings to a Gilzor-only execution path. A high-quality audit used elsewhere is still a good outcome for us.

What does the audit not cover?

No marketing strategy, ASO copywriting, revenue projections, or security penetration testing as a primary deliverable. We diagnose product and code issues and recommend technical fixes. We don’t pretend to be McKinsey.

Is there an NDA?

Yes. Standard NDA is signed before any access is granted and before any confidential information is shared. The audit report is confidential and delivered only to the client.
