The Analyzer is a combination of a sound pressure level (SPL) meter and a full range multiple bands frequency analyzer. It is mainly designed for audio professionals who need to evaluate different working environments (e.g. studios, live stages)... that’s why it’s perfect for anyone who’s in need of acoustical analysis!! It is easy to use and comes with amazing features only known from professional acoustic tools. Use the Analyzer for measuring stages, testing speakers, setting up your hi-fi system, evaluating sound mixing environments, analyzing your instrument... or for measuring the noise your neighbor makes with his new stereo! The Analyzer is pre-calibrated for all iDevices, but it includes a calibration function as well. It comes with a highly intuitive user interface with zoom gesture control, individual color settings, reticle zoom and many more exciting features. The Analyzer can store, load and export measurement data and supports iCloud storage. Combine the Analyzer with external microphones such as the MicW i436 or Microtech M372 for better measurement performance! Or use it with external USB audio hardware like the RME Fireface UCX or the Alesis IO dock, change the measurement scale to dB (FS) and use it as a studio Realtime Analyzer!

BFM or Big F*ing Meters is a macOS, Windows, and soon to be iOS compatible Metering plug-in designed exactly how the name sounds... really f*ing big. With the main goal of readability we wanted to bring a meter that you can see from across the studio and keep your records clip-free. BFM currently offers 6 Modes with RMS, LUFs, Peak, and Peak Hold values, to give you a variety of views to keep your signal under control. The Text, Bars, Waves, VU Meters, Spectrum, & Time let you decide how you want to keep track of your signal with multiple fonts/formats to view them in. Text gives you a quick look at just the values easy to see from across the room. This view offers the most values with RMS, Peak, Peak Hold, and LUFs (Short Term & Momentary with Maximum values and LUFS range) values available. Controllable sensitivity & peak hold time for all pages. Reset Peak Hold with a click off the value. Bar offers a more traditional meter for seeing the range of values showing RMS, Peak, Peak Hold, and LUFS. Correlation & Balance meters included to set your stereo image and phase response. Peak Hold resets on value click. Sensitivity changes on bar click. LUFS readings select on click. Included reference points for -24 (EBU), -16 (Apple Music), & -7 as a suggested maximum for most genres. Wave view gives you a look at your waveform after your channel effects with the ability to quickly mark in dB where you want to see your signals peak. To freeze click the waveform. To reset Peak Hold click the value. VU Meter Designed for a quick look at your overall levels. Featuring controllable Attack, Release, Minimum, and Maximum value control. Left/Right, Mid/Side, PPM, and LUFS options available. Click VU to enter dark mode. Spectrum is a simplified frequency spectrum view with 3 quality modes. Great for getting an overall look at where your frequencies are when mixing or editing. Tap to freeze and inspect. There is also the PEAK value displayed on this page. To reset Peak Hold click the value.

Verdict
The clearest difference is review sentiment: BFM at 100% against Analyzer's 47%. BFM also leads on price ($4.99 vs $14.99) and rating (4.6 vs 2.9). Analyzer's advantage is update cadence (every 6 weeks vs every 5 months). On ratings volume, ads, device support and iOS requirement there is nothing between them.
