Why London matters for app testing
London brings its own quirks. Sites there personalise pricing, stock and even page layout by visitor origin, so a request from a foreign datacenter IP describes a market that doesn't really exist. Only in-country addresses reveal what a genuine local user sees — which is exactly why app testing needs local exits here.
Best proxy type for app testing
For app testing, we recommend Mobile Proxies as the default in London, United Kingdom. They give you the trust profile this workload needs, and a sticky session strategy suits how app testing traffic behaves. Datacenter IPs are cheaper but get flagged faster on the strict targets app testing usually involves.

How to set up proxies for app testing in London, United Kingdom
Pick a provider and plan
Start with a network that offers Mobile Proxies covering London. Cheapest Proxies has a free trial, so you can validate coverage before committing a budget to app testing.
Target London in the dashboard
Set the location to London (city or ASN where offered), choose sticky sessions, and copy your gateway endpoint plus credentials.
Wire it into your app testing tool
Point your scraper or automation at the proxy endpoint, add authentication, and set sensible concurrency and retry limits tuned for app testing.
Verify and scale
Run a small batch, confirm exits resolve to London and success rates hold, then scale up gradually while watching cost per successful request.
Mistakes to avoid
- Rotating on every request when app testing actually needs a sticky session to stay logged in.
- Hammering targets with no delay, which gets even good IPs burned fast.
- Skipping the free trial and discovering coverage gaps only after paying.
- Using datacenter IPs on London targets that fingerprint and block them instantly.
