hEARtest vs PlugBrain
Side-by-side comparison of two open source alternatives
hEARtest
This app can evaluate your hearing capabilities. The term dB HL describes your hearing loss in decibels. The table below shows a common way to classify hearing loss (Source: Clark, J. G. (1981). Uses and abuses of hearing loss classification. Asha, 23, 493–500.) Degree of hearing loss: dB HL range Normal: –10 to 15 Slight: 16 to 25 Mild: 26 to 40 Moderate: 41 to 55 Moderately severe: 56 to 70 Severe: 71 to 90 Profound: 91+ First your earphones must be calibrated. You can either perform a full test which requires one or better several persons between the ages of 18 and 35 with normal hearing. Or you can perform a simple calibration at 1000Hz only (assuming good hearing at this frequency). In this case it is assumed that the earphones are linear across the frequency range and calibration values for the other frequencies are then calculated using the ISO226:2003 standard. Whenever you hear a beep simply touch the screen. You can pause / continue with a long click and speed up with a double click. If you have several persons available for calibration simply press "Add Calibration" and an average value of existing calibrations will be calculated. You may also delete the whole calibration. After that you can perform tests and view them in test results. You can then also perform tests at single frequencies. There you can manually select ear, frequency, and sound amplitude by clicking on the buttons. Required permissions: - Microphone - External storage for backup/restore No ads, no trackers.
PlugBrain
PlugBrain is an app that encourages regular breaks from distracting apps by blocking access at scheduled intervals. To regain access, you’ll need to solve a math challenge that adjusts in difficulty: the more frequently you use the apps, the harder the challenges become, but the longer you stay away, the easier they get. **Features** - No ads - No internet required - Blocks distracting apps - Unblock apps by solving math challenges - Difficulty increases with frequent use, decreases with focus **How to use** - Grant all required permissions - Select distracting apps - Choose your focus interval - Stay focused ;)
