This is the standalone bookmarks manager android app variant of floccus. You can also install floccus on your Desktop browsers to sync bookmarks with them. This App, due to technical reasons, cannot access bookmarks in your mobile browser apps directly, which is why you can only view them in the app or import and export them as a html file.

hEARtest
APK
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.

hwloc lstopo
APK
The Portable Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information as well as the locality of I/O devices such as network interfaces, InfiniBand HCAs or GPUs. hwloc primarily aims at helping applications with gathering information about increasingly complex parallel computing platforms so as to exploit them accordingly and efficiently. For instance, two tasks that tightly cooperate should probably be placed onto cores sharing a cache. However, two independent memory-intensive tasks should better be spread out onto different sockets so as to maximize their memory throughput.

jtx Board journals|notes|tasks
APK
Elevate the power of the iCalendar standard to the next level, use the potential of the combination of journals (VJournal), notes (VJournal) and tasks (VTodo) out of one app and use DAVx5 to synchronize your entries with a CalDAV-server of your choice! iCal standard compliant Using the iCal standard ensures compatibility and interoparability with other apps and services independent of a dedicated provider or infrastructure. Journals and Notes are compliant to the definition of the VJOURNAL component, Tasks are compliant to the VTODO component. Future features will also include import and export functionalities to and from .ics files :-) Combine journals, notes & tasks Instead of using separate apps for journals, notes & tasks you can use them out of one hand, combine and link them to each other, e.g. create meeting minutes and link your tasks to them. Sync with DAVx5 Synchronize your entries with any compatible CalDAV server by using DAVx5. By using DAVx5 you are free to choose your preferred provider for CalDAV, you can even use your local server to store and synchronize your data. Note: DAVx5 is an independent app and must be acquired separately. Open Source Your data can contain private and sensitive data by their nature. We believe that individuals and companies should be able to be in full control of their own data. This means the freedom to choose where and how the data are stored, and freedom in choice of software. That is why we chose DAVx5 as a Sync Adapter to synchronise your data between your phone and any compatible CalDAV-server. The source code for jtx Board is publically available - find out more on https://jtx.techbee.at ! What does VJournal and VTodo mean? VJournal and VTodo are calendar components defined in the international standard RFC-5545, the Internet Calendaring and Scheduling Core Object Specification (iCalendar), see https://datatracker.ietf.org/doc/html/rfc5545 . This standard also defines the VEvent component, which is the standard definition for calendar event entries. jtx Board is using the VJournal component according to this iCalendar standard for journal entries and tasks. VJournals can have a defined start date, but they cannot have a duration or an end date. VJournals with a defined start date are considered journals entries in jtx Board, VJournals without start date are interpreted as notes. The VTodo component as defined in the iCalendar standard defines the technical specification of tasks, which can have a scheduled start, due and completed date as well as a progress and a completed status (amongst others). The VEvent definition is widely used, the VTodo component also found some implementations in Apps, but the VJournal component remained in the dark almost not being implemented at all by other apps and services. With jtx Board we would like to revive the usage of this standard and empower it with the possibilities to link and combine VTodos with VJournals - and in the future also VEvents! :-) Find out more on https://jtx.techbee.at
