echolot

Measure, don't guess.

Free Android diagnostics for the layer where networks actually break. Echolot takes the failure you can feel and pins it to a fact you can show — no root required. Built for people who know what a neighbor table is.

What it measures

Signal bars lie. Timings don't.

Most wifi apps show you signal strength and call it a diagnosis. The failures that ruin home and office networks live deeper: a second DHCP server nobody admits to, IPv6 router advertisements gone wrong, an MTU black hole that only eats large packets, multicast dying quietly at the AP, a resolver answering differently than it should.

dhcp.rogue_detectWho is answering DISCOVER — and is it more than one box?
ipv6.ra_auditRouter advertisements: lifetimes, flags, prefixes that shouldn't be there
mtu.blackholePath MTU probing — find the packet size where the network goes silent
local.mdns_discoverDoes multicast actually survive your AP? What's announcing itself?
dns.canaryCompare answers against reference records — catch rewriting resolvers
trace.errqueueTraceroute without root, straight from the kernel error queue

Every run separates what was observed from what it means, and exports as JSON — so the evidence survives the argument.

Privilege tiers

No root required. More access if you have it.

Everything above runs as a plain app. Pair once over wireless ADB with Shizuku and Echolot additionally reads neighbor tables, RA-installed routes, and DHCP client logs — still no root. Every result records which tier produced it.

app — no setup, the bulk of it shizuku — wireless ADB pairing, in v1 root — future module

Pre-release. The capability prober is running on real hardware; the production app is under construction. These links go live with the first release — until then they loop back here. No mailing list, no tracker: check back, or watch the repository.

releases will ship with sha256sums + a signing key you can pin
