PillMinder vs Spectrum Analyzer+ Audio FFT

Do you take a lot of pills and find it hard to keep track of them all? Or, do you want to know how many pills you have left of a given kind when you go shopping so you can fill up your prescription? Or, are you the forgetful kind that doesn't remember whether you took your pills today? If you said "Yes" to one (or more) of the above, then PillMinder is for you! PillMinder allows you to easily track when you take a pill - simply tap the handy status indicator button next to each pill and it's recorded. The status indicator also shows you when you're due to take any of your pills by changing the button from a red x (indicating that it's too early) to a green check mark. What's more, the application keeps track of when you took a given pill and what your dosage was at that time. So you can always use the "History" button to go back and check what your dosage was over time and when your dosage changed. But that's not all. PillMinder also lets you keep track of how many pills you have and deducts from the inventory based on your dosage when you take a pill. So, the application will always have an updated count of how many pills you have left and you can see this information, as well as how many days you have pills left for, on the main screen. Basically, you can see all of your medication related information on one screen! If you take more than one dose of a given pill for a given day, PillMinder can handle that too. Are your pill dosages not whole numbers? Not a problem! PillMinder will deal with that easily. PillMinder will also remind you when you need to take your pills next. And you can keep photos of your pill bottles and pills for each individual pill. If you are not sure how to use PillMinder, there's also a handy visual guide which is included in the app itself. Simply use the action button on the top right corner of the main screen to access the built-in help. If that isn't helpful enough, feel free to contact us via the built-in Feedback which is also available via the action button. Note: The basic version of the app is fully functional but is ad-supported. So the app will display an ad banner at the bottom of each screen. If you don't want to see the ads, you can upgrade to the Pro version, which removes the ad banners. If you like PillMinder, please take the time to give us a nice review: it really helps.

Spectrum Analyzer+ Audio FFT shows the live frequency spectrum of any sound your iPhone microphone hears, then lets you capture a 5-second average and read the result: the strongest frequency in Hz, the top components and where the energy sits. ▶ See the spectrum live • 32 bands from 20 Hz to 20 kHz, computed with a 2048-point FFT • Four views: Bars with peak hold, Line, Waterfall and Spectrogram • Peak frequency and peak level update as you listen • Min / Max traces in the Bars view, tap a bar for a cursor readout, freeze the display to study it • Adjustable dB range from 30 to 120 dB ▶ Capture 5 seconds, get an answer Tap Capture 5 s under the graph and hold the sound steady. The app power-averages the spectrum over five seconds and shows a result card: • Strongest component in Hz, with the musical note and cents in Voice mode • Up to three top components with their levels • Share of the detected energy in the low, mid and high part of the selected range • Strongest band level and the FFT resolution of the measurement If the sound is too quiet in that range, the card says so instead of inventing a peak. ▶ Compare before and after Save a capture as a reference (up to 10). Make a change — move a speaker, add treatment, adjust a machine — capture again in the same mode and the card shows the average band-level difference in dB. References can also be overlaid on the live spectrum. ▶ Pick the job • Voice: 80–4000 Hz, shows the note of the strongest pitch • Machine: 20–2000 Hz, looks for 50/60 Hz mains hum and its harmonics • Room: 20–500 Hz, the low end where room modes build up ▶ Export and share • Export a CSV of the live spectrum or of a 5-second capture • Share a short text summary of a capture ▶ Extras • Calibration offset from −20 to +20 dB in 0.5 dB steps to line up with a reference meter • Pink noise generator, unlocked for 24 hours by watching a short ad • Interface in 30 languages ▶ Good to know Levels are relative to the microphone's full scale (dBFS). A phone microphone is not a certified sound level meter, so use the numbers to find frequencies and compare changes, not for compliance measurements. Audio is analysed in memory while you listen and is not saved as a recording. For musicians checking a tone, home studio and hi-fi owners chasing a boomy note, and anyone tracking down a hum from a fridge, fan or transformer.
