dialysisPal. Open. Enter. Leave. I built this app because I got tired of waiting for my own data. I've been on peritoneal dialysis since 2016. Like most PD patients, I started tracking my treatment with pen and paper. Then a spreadsheet copied from my nephrologist's template. Then Airtable. It worked fine, except that opening it, entering my numbers, and waiting for the sync took one or two minutes every single time. That doesn't sound like much. But when you do it twice a day, every day, those minutes add up. Eventually I thought: I can build something faster. So I did. I've been using dialysisPal myself for almost a year now. It does exactly what I need, and nothing else. What dialysisPal tracks: Set up your profile once (your dialysate type and cycler configuration), then log your daily treatment in seconds: • Morning: ultrafiltration amount from your overnight treatment, dwell time, weight, blood pressure, pulse • During the day (optional): interim drainage if you do a midday drain • Evening: the rest of the day's drainage, plus your evening weight, blood pressure, and pulse That's all of it. No features you won't use, no menus to navigate. Open the app, tap in your numbers, you're done. Why tracking matters: Day to day, you feel fine. Your blood pressure looks normal this morning. Your weight hasn't changed much since yesterday. Everything seems okay. The tricky thing about peritoneal dialysis is that the problems that matter creep up slowly. Fluid builds up gram by gram. Blood pressure rises point by point. Any single reading tells you almost nothing. The trend tells you everything. dialysisPal makes that trend visible. Charts show you what's actually happening over time, not just what today felt like. What else it does: • Trend charts — ultrafiltration, weight, blood pressure, and drainage patterns over time • Export — generate PDF or CSV reports for your nephrologist appointments • HealthKit integration — your weight and blood pressure sync with Apple Health • iCloud sync — your data stays backed up privately across your iOS devices Sanity checks — catches obvious entry mistakes (like typing 700 kg instead of 70 kg) • Offline — works without internet • Accessible — full VoiceOver support, Dynamic Type, WCAG AA compliance A few honest things: This is version 1. I use it myself every night, and it does what it needs to. The app is a one-time purchase. No subscription, no ads, no analytics, no account needed. Your data stays on your phone. I'm not a medical device company. Not a startup with a growth team. I'm someone who does PD every night and wanted a tracker that didn't waste my time. Now I'm sharing it with you. Built by a patient. For patients. Questions? support@dialysepal.de

DD420 is a private wellness companion for veterans managing PTSD who also use cannabis for symptom relief. No judgment. No politics. Just tools. Your data never leaves your device. No accounts. No ads. No one is watching. DAILY CHECK-IN Track your PTSD symptoms using the same four clusters the VA uses — Intrusion, Avoidance, Mood & Thinking, and Alertness — in a guided, one-step-at-a-time flow built to feel less overwhelming. Rate each area honestly, log your mood and sleep, and note what triggered you. Takes less than two minutes, and your progress saves automatically if you get interrupted. Over time, your check-ins build a picture of how you're actually doing — not how you think you're doing. CANNABIS SESSION LOG Log each session with strain, method, THC and CBD content, timing, and — most importantly — why you used it and whether it helped. Select from 12 veteran-specific conditions including PTSD symptoms, chronic pain, sleep and insomnia, nightmares, anxiety, hyperarousal, and more. Each condition has its own curated list of effects to track. You'll start to see which strains, methods, and dosages actually move the needle for your specific symptoms. INSIGHTS Charts built from your own data. See your symptom severity trend over time, which PTSD clusters affect you most, how sleep quality relates to your symptom scores, how cannabis use correlates with next-day symptoms, and which conditions you use most. The more you log, the clearer the patterns become. COPING TOOLS Evidence-based tools organized by what you need right now. Breathing exercises, grounding techniques, progressive muscle relaxation, sleep visualization, and urge surfing — available any time, no subscription required. TOLERANCE BREAK TRACKER Set a break goal, track your progress day by day, and get coping prompts for cravings. Includes plain-language education on what tolerance is and what to expect during a break. 100% FREE Every feature in DD420 is free. Always. No subscriptions, no locked features, no paywalls. If you want to support development, an optional one-time tip ("Buy Me a Bag") is available in Settings — never required. BUILT FOR VETERANS Veterans Crisis Line: 988, press 1 — call or text directly from the app, one tap, any time. Chat: veteranscrisisline.net DD420 is not affiliated with the VA or DoD.

Verdict
The clearest difference is price: DD at Free against dialysisPal's $5.09. DD also leads on ratings volume (15 vs 1) and iOS requirement (17.6 vs 26.0). dialysisPal's advantage is in-app purchases (none vs 3). On rating, update cadence, ads and device support there is nothing between them.
