Feasibility assessment
Which native features a PWA can and cannot replace.
Mobile App to PWA
Reach users without store friction or fees.

Why It Matters
Why Mobile App to PWA Needs a Specialist Approach
If an app is mostly content, forms or catalogues, a PWA can cut store fees and update delays. We assess whether a PWA meets your needs, then migrate features and keep an app-store path open where it still helps.

Bottlenecks and Fixes
Where Mobile App to PWA Projects Get Stuck, and How We Design Around It
Store dependency
The bottleneck. Policy changes and fees threaten the business.
How we design it. A web-based channel you control.
Target result: 0 data loss target
High acquisition friction
The bottleneck. Users abandon downloads.
How we design it. Try-before-install via link or QR code.
Target result: Minutes typical cut-over downtime
Maintenance cost
The bottleneck. Several store builds need constant updates.
How we design it. One web codebase deployed continuously.

Travel
Bottleneck: Travellers need offline itineraries.
Our design: Offline-ready trip and ticket views.
Events
Bottleneck: One-time use apps waste downloads.
Our design: QR-launched PWA with live updates.
Services
Bottleneck: Customers book occasionally.
Our design: Lightweight booking PWA.
Migration Risk Control
Migration Risks and How We Remove Them
Migrations fail in predictable ways. We plan for each one before the first record moves.
Data loss or corruption
The risk. Records are altered or dropped during transfer.
Our safeguard. Checksums, record counts and sampled comparisons at every trial load.
Extended downtime
The risk. Users locked out during the switch.
Our safeguard. Continuous replication and a rehearsed, time-boxed cut-over.
Feature regressions
The risk. Behaviour differs from the old app.
Our safeguard. Automated regression suite and side-by-side user acceptance tests.
Lost reviews and users
The risk. Store changes reset ratings or break updates.
Our safeguard. Same bundle IDs, transfer-safe processes and staged rollouts.
Security gaps
The risk. New environment is configured loosely.
Our safeguard. Hardened landing zone, secrets management and access reviews.
Cost overruns
The risk. Cloud or licence costs exceed forecasts.
Our safeguard. Right-sizing, budgets and alerts from the first week.
