We compared Fast ★★☆☆☆ with RealSpeed ★★★★★ and concluded that RealSpeed is a better speed test than Fast.
This is mainly because RealSpeed measures your router speed and your device speed.
The radar chart above is based on the results of our standardized speed test test. The results speak for themselves.
Strengths of Fast
By far Fast's strongest point is its usability. The speed test starts automatically, and has an interface that clearly shows one thing, namely the measured download speed.
In addition, you can easily pause the test. Furthermore, Fast is ad- and cookie-free.
It is therefore not surprising that Fast scores high on the list Usable speed tests and on the list Privacy respecting speed tests.
Strengths of RealSpeed
The strongest point of RealSpeed is without a doubt that this speed test performs two speed tests. One from the router and one from the device in use. Both speed tests are accurate.
This gives you direct insight into whether your ISP delivers the promised speed. This makes it immediately clear what the cause is of any performance problems.
RealSpeed starts up instantly, doesn't show ads, and seems fairly frugal in terms of data usage (although we can only determine this at 50%, as we couldn't determine data usage during the router test).
Our recommendation
Based on what we know about speed tests, if we had to choose between these two speed tests, we would choose RealSpeed over Fast. The deciding factor is the accuracy of RealSpeed in both the router test and the device test.
