We have all experienced those rides where something mechanical happens that really was preventable. As the authors, even though we take a certain pride in our own efforts in maintaining smooth running MTBs, and a disdain for our riding buddies who never give a passing thought until something goes 'CRUNCH!' in a ride-ending manner, there are still innumerate situations where something that should have been checked, or usually never needs checked after proper installation, has not been. 'Where is that vibration coming from?', 'why is the rear end creaking?', 'What is that terrible knocking?' are so often result of something relatively simple being overlooked or forgotten. Recent favourites have been disc rotor bolts backing out, rear thru axles not done up properly, and headsets improperly tensioned. So, to prevent mechanical disasters happening on your rides, use this app to build better, new, habits and ensure your rides are (mechanically) glorious. The app can connect ot Strava and update mileages/distances as well as last ride dates. This app uses INTERNET and ACCESS_NETWORK_STATE permissions to download template activities from a github repository at https://github.com/janexner/JKBikeTemplateActivities, and to retrieve data from 3rd-party integrations, currently with Intervals.icu only. No internet access beyond that.

Keep Alive will send a custom message via SMS to one or more people if you haven't used your device in a given period of time. Intended to be used as a failsafe for those living alone in case of an accident or other emergency. Once the settings are configured, no further interaction is required. - 100% Device-based, no cloud services or accounts required - Free with no ads or trackers - Open Source (https://github.com/keepalivedev/KeepAlive) - Minimal Battery Usage - Multiple SMS Recipients - Custom Alert Message - Optional: Include Location Information in SMS - Optional: Place a phone call with speakerphone enabled - Optional: Send an HTTP request to a custom URL Requirements Keep Alive requires that your device has an active cellular plan. WiFi calling and messaging will be used if the device supports it. How it Works Keep Alive uses either your device's lock screen or another app(s) to detect activity. If your device hasn't been lock or unlocked for a set period of time, or if you haven't accessed the selected app(s), you will be prompted with an 'Are you there?' notification. If this notification is not acknowledged an Alert will be triggered. Based on the configured Emergency Contact Settings, one or more SMS messages and/or a phone call will be placed to notify others that you may be in need of assistance. WARNING: If your device restarts, Keep Alive will not be able to check for recent activity until the screen is unlocked. On Android 7.0+, Keep Alive can still send an alert before the screen is unlocked but must assume you have been inactive based on its last saved state. On older Android versions, Keep Alive cannot run at all until the screen is unlocked and alerts will not be sent. Main Settings - Monitoring Method - Choose between using the lock screen or another app(s) to detect activity. If using another app(s), you will be prompted to select the app(s) to monitor. - Hours of Inactivity Before Prompt - how many hours since your phone was last locked or unlocked before you are prompted with an 'Are you there?' notification. Defaults to 12 hours - Minutes to Wait - if the prompt is not acknowledged within this time, an Alert will be sent based on the configured emergency contact settings. Defaults to 60 minutes - Rest Period Time Range - a range of time during which inactivity will not be counted. For example, with 'Hours of Inactivity' set at 6 hours and a Rest Period of 22:00 – 6:00, if the device is last used at 18:00, the 'Are you there?' check would not be sent until 8:00. Note that an alert can still be sent during a rest period if the 'Are you there?' check was sent BEFORE the start of a rest period. - Auto-Restart Monitoring After Alert - If enabled, monitoring will be automatically restarted after an Alert is sent. - Alert Webhook - Configure an HTTP request to be sent when an Alert is triggered Emergency Contact Settings - Phone Call Number (Optional) - when an Alert is triggered a phone call will be placed to this number with speakerphone enabled One or more SMS recipients can be configured with: - Phone Number - the phone number to send the Alert SMS to - Alert Message - the message that will be sent when an Alert is triggered - Include Location - if enabled, your location will be included in a second SMS Privacy/Data Collection No data is collected other than the configured settings and nothing is shared with the developers or any 3rd parties.

Libellus Potionis is a privacy-first, free, open-source and ad-free alcohol consumption tracker. It helps you monitor, pace and manage your drinking entirely offline. It needs no invasive permissions — no camera, microphone or location — and works completely without network access. KEY FEATURES * Intelligent logging: predefine your own beverages or pick from internationally common presets. Log drinks instantly or retroactively with precise timestamp corrections. * Concurrent limit tracking: set three simultaneous boundaries — a daily limit (grams of pure alcohol), a rolling 7-day weekly limit (grams), and a maximum number of drinking days per week. Visual progress bars keep you informed in real time. * Blood Alcohol Concentration (BAC) estimate: enter your body weight to get a live approximation based on the established Widmark formula. * Counseling reports: generate a clear, well-organized two-page PDF report designed for consultations and counseling appointments, summarizing your habits statistically. * Data portability: export your full dataset as a standard CSV file for external processing (e.g. in LibreOffice Calc), or create secure JSON backups to move data between devices. * Granular adjustments: customize your "day start" time so late-night drinks count toward the correct evening, and set custom evaluation start dates for clean restarts. A comprehensive User's Guide is available inside the app. PRIVACY & SECURITY Libellus Potionis is built around absolute data sovereignty and strict data minimization. It runs under a minimal permission profile that completely excludes network access, so your personal data never leaves the device. Your data stays in the app's private storage, protected at rest by Android's device storage encryption and the app sandbox. An optional biometric fingerprint lock guards against unauthorized physical access. This offline-first approach eliminates tracking, cloud synchronization and external data leaks. COMPATIBILITY The app runs on Android 11 (API 30) and newer. A fully independent in-app language selector works across all supported versions, regardless of the system-level per-app language picker. OPEN SOURCE Libellus Potionis is free software released under the GNU General Public License v3 (or later). The source code is documented to a textbook standard and is available at the canonical repository: https://codeberg.org/godisch/potillus/
