SignalLab
Android · free to measure · Pro EUR 4.79 one time
Every test signal, honest about your speaker.
Generates sine, square and triangle waves, white, pink and brown noise, sweeps and speaker checks. Levels are honest dBFS, loops are seamless, and it plays the exact sweep RoomLab measures with, from a second phone. It only plays: like SkillLab, it has no microphone permission.

Measuring is free and complete, so you always see every value. Pro is a one-time purchase through Google Play, no subscription, and it unlocks the report and the tools, never your own data. You buy it inside the app, on the report screen, and it comes back with the same Google account on a new phone.
