Ancel Echo Review: A Great Idea That Failed on Real Cars Iamcarhacker

Published: October 13, 2024 · Last updated: June 4, 2026

The Ancel Echo is a smartphone-based diagnostic tool that promised full-system access and bidirectional tests without subscription fees. I tested it on a Toyota Corolla, a Fiat Punto and a Renault Kangoo. On paper it looked like a great deal, but it failed on two of my three test cars, and now that the cheaper Mucar BT200 Max does the same job better, there’s no real reason to buy the Echo. Read on for what went wrong.

What it’s actually good at

On an easy modern car it does everything it claims, and that’s the trap. On the Toyota Corolla 2022 the Echo scanned all modules, ran bidirectional tests, showed live data and generated a report, all cleanly. If you only ever tested it on a Toyota, you’d think it was a great device. It has its own full-system app and also connects to ELM327 apps, so the concept is sound: pro-style functions through your phone with no monthly fee.

The build quality is decent too. The idea behind the Echo, full-system plus bidirectional without subscription, was genuinely valuable when it launched. It’s worth knowing Ancel is a sub-brand of Thinkcar, which is why the Echo app shares Thinkcar’s software DNA, including the same AI fault-code assistant. The problem is everything that happens once you leave easy cars.

Where it falls short

It fell apart on two of three cars, and that’s the whole story. On the Fiat Punto 2004 the scan was painfully slow: a quick scan took around 10 minutes just to find three modules (it should find at least four), then I couldn’t enter those modules without running a second scan, and when I opened live data the app disconnected. I first blamed the battery, but the dash lights came straight back and the car started fine later, so the disconnect was the Echo app, not the car.

The Renault Kangoo was worse: it doesn’t support the entire Renault brand. Not a missing model, the whole brand. Most tools in this class cover 80+ brands. And the real problem was that even basic OBD reading failed in the Ancel app, I had to switch to a regular ELM app just to reach the engine module. A full-system tool that can’t connect to an entire brand, or even read basic OBD on it, is a serious gap.

Scans are slow, coverage is narrow, the app is unstable, and the long feature list is useless on any car it doesn’t properly support.

Who should buy this

Honestly, almost nobody, and here’s the straight version:

Maybe consider it if:

You only work easy modern cars (like late Toyotas) and find it cheaper than the alternatives below

Look elsewhere if:

You work a mix of brands, especially European, the coverage and stability aren’t there
You want reliable full-system through your phone, the cheaper Mucar BT200 Max does it better and also runs ELM apps
You value fast, stable scans, the Echo struggled badly on older cars

How it compares?

Ancel Echo

Mucar BT200 Max

→ Mucar BT200 Max, cheaper and far more capable: full-system diagnostics, bidirectional, and it also connects to ELM apps, so it replaces the Echo completely. This is the tool I'd point you to instead, full stop.

Ancel Echo

XTool A30M

→ XTool A30M, the best-value Bluetooth scanner I've tested, smoother and more reliable across brands. If you want a phone-based tool that just works, this is the one I recommended over the Echo. The comparison shows why.

Ancel Echo

Konwei Kdiag

→ Konwei KDiag, an ultra-budget full-system bidirectional adapter (great on Japanese cars, weak on VAG). Even this cheaper tool is a more honest buy than the Echo for most people. See how it compares.

Still deciding rather than chasing an Echo deal? I line up the budget Bluetooth scanners I’ve tested in my [best Bluetooth OBD2 scanners] roundup. The short version: the Echo is hard to recommend now, and the roundup shows which phone-based tool actually earns the money.

Final word

The Ancel Echo looked great on paper but failed on two of my three test cars: slow scans, missing entire brands, app disconnects and unstable performance. Today the Mucar BT200 Max is cheaper and far more capable, and since it connects to ELM apps too, it replaces the Echo completely. I like Ancel as a brand, their basic code readers are solid, but if you want real full-system diagnostics through your phone, skip the Echo and use the BT200 Max or a proper multi-brand tool.
