Yes. A drum tuning app will work the same way that a digital tuner does. It records the frequencies of the drums you’re playing and allows you to match the tension around the head. However, drum apps never tend to be as accurate as physical tuners. If you’re using one to get a general idea of how well your drums are tuned, go for it! If you need to tune your drums for a huge recording session, I’d consider using a dedicated drum tuner. I know some popular drum tuning apps, iDrumTune Pro and Drumtune PRO.
