CKD Tracker
Chronic Kidney Disease Companion
Log eGFR, creatinine, blood pressure, fluid intake, potassium, phosphorus, and medications in one place. CKD Tracker is built for people living with chronic kidney disease who want a clean, organized record of every lab, every symptom, and every change between nephrology visits.
Supports CKD stages 1 through 5, dialysis prep, transplant follow-up, and renal-diet tracking for sodium, potassium, phosphorus, and protein.
- Lab trend tracking for eGFR, creatinine, BUN, albumin, potassium, and phosphorus
- Renal-diet log with sodium, potassium, phosphorus, and protein targets
- Blood pressure and fluid-balance log to help spot fluid retention early
- Medication schedule with phosphate-binder reminders and renal-dose flags
Free to download. Also available on Google Play. CKD Tracker is a self-tracking tool, not a medical device, and does not diagnose, treat, or prescribe.
Inside the App
Log labs, track blood pressure trends, monitor fluid balance, log every meal against renal-diet targets, and stay on top of medications between nephrology appointments.
Screens for lab entry, eGFR and creatinine trend charts, blood pressure log, renal-diet meal tracking, and medication schedule.
Your Chronic Kidney Disease Care Plan
CKD Tracker ships with a guided care plan for people living with chronic kidney disease so you are not guessing what to log between visits. It covers the four things that move the needle most for kidney health: labs, blood pressure, fluid and electrolytes, and the renal diet.
Log eGFR, creatinine, BUN, albumin, potassium, phosphorus, calcium, hemoglobin, and urine albumin-to-creatinine ratio. CKD Tracker plots each marker over time so you can see whether kidney function is stable or declining, not just whether todays number is high or low.
Tight blood pressure control is one of the strongest levers in slowing CKD progression. Log home readings morning and evening, see weekly averages, and watch for trends your nephrologist will want to discuss before they show up at a clinic visit.
Track daily fluid intake against your clinician-set limit, log daily weight, and watch for fluid retention patterns. CKD Tracker flags sudden weight gains that may signal fluid overload and helps you stay inside potassium and phosphorus targets.
Log meals against renal-diet targets for sodium, potassium, phosphorus, and protein. Schedule phosphate binders with meals, ACE inhibitors or ARBs at the right time, and diuretics so nothing slips. Every entry feeds the report you share with your renal team.
Why Tracking Matters for Chronic Kidney Disease
CKD progresses quietly. Most of the levers that slow it down — blood pressure, diet, fluid balance, medication adherence — only work if you stay on top of them every day, not just on the day of a clinic visit.
Kidney function tends to drift, not crash. eGFR can fall a few points a year without you feeling any different until late-stage disease. By the time symptoms appear — fatigue, swelling, nausea, itching, breathlessness — significant function is already lost. The only way to catch early changes is to keep a structured log of labs, blood pressure, weight, and how you actually feel between appointments. CKD Tracker turns those scattered notes into a clear timeline you and your nephrologist can read in a glance.
Blood pressure is the single biggest modifiable risk factor for CKD progression. Major nephrology guidelines target tight control because every sustained 10 mmHg reduction in systolic pressure is associated with measurably slower decline in kidney function. A clinic reading once every few months cannot tell you whether your average is on target. Two readings a day, logged for a week, can. CKD Tracker is built around that cadence.
Diet is the second biggest lever. Sodium drives blood pressure and fluid retention. Excess dietary potassium and phosphorus become harder for failing kidneys to clear, raising risk of arrhythmias and bone disease. Protein has a tradeoff — too much accelerates filtration stress, too little undermines nutrition. None of this is intuitive. Logging meals against renal-diet targets turns dietary decisions into something you can see and adjust, instead of guess at.
Finally, tracked data protects you when the unexpected happens. A sudden change in lab values, a hospitalization, a new prescription that interacts badly with your renal-dosed medications — every one of these is easier to investigate when you can hand a clinician a structured log of the past 90 days instead of trying to remember it. CKD Tracker is built so that record is always one tap away.
What You Can Expect
Based on how structured self-tracking tends to work across chronic conditions, consistent use of CKD Tracker over 30, 60, and 90 days typically surfaces patterns like these.
Clearer Lab Trends
Instead of comparing two lab dates from memory, you see eGFR, creatinine, potassium, phosphorus, and albumin plotted over months. By the third lab draw, you can tell stable from drifting at a glance, and you walk into nephrology appointments with a real conversation starter.
Tighter Blood Pressure Control
Twice-daily logging reveals whether your true average is on target, not just your clinic reading. Most users see a tighter, more consistent pattern within the first month as small triggers (missed doses, salt-heavy meals, poor sleep) become visible and easy to adjust.
Earlier Fluid-Retention Detection
Sudden weight gain over two to three days is one of the earliest signs of fluid overload in CKD. Daily weight logging makes those small jumps visible immediately, so you can adjust salt and fluid before symptoms force a clinic visit or an ER trip.
Better Renal-Diet Adherence
Logging meals against sodium, potassium, phosphorus, and protein targets converts an abstract diet into a daily score you can actually see. Most users find that within two weeks they recognize the meals that quietly drive potassium and phosphorus too high and naturally swap them for renal-friendly options.
Higher Medication Adherence
Phosphate binders with meals, ACE inhibitors or ARBs at the right time, diuretics and erythropoietin-stimulating agents on schedule. Reminders plus a visible adherence percentage often raise day-to-day consistency from a guess to a reliable habit within the first month.
Portable Records for Your Nephrologist
Export a clean PDF for your nephrologist, dietitian, or primary care doctor. Instead of recalling the last 90 days from memory, you hand them a structured timeline of labs, blood pressure, weight, symptoms, and medication adherence.
Individual results vary. CKD Tracker supports self-tracking and is not a substitute for a nephrologist, dietitian, or other licensed healthcare professional. Always follow the care plan set by your clinical team.
Understanding Chronic Kidney Disease
CKD is a progressive loss of kidney function measured in five stages. Different stages call for different tracking focus, and CKD Tracker adapts to whichever stage you are in.
Stage 1 and Stage 2 CKD. Kidney function is still relatively preserved (eGFR above 60), but there is evidence of damage — usually albumin in the urine, an abnormal imaging finding, or a genetic kidney condition. The tracking focus at this stage is prevention: blood pressure, blood sugar if diabetic, weight, and the urine albumin-to-creatinine ratio. CKD Tracker treats these years as the most valuable window to keep eGFR stable for as long as possible.
Stage 3 CKD. eGFR between 30 and 59, often split into 3a (45 to 59) and 3b (30 to 44). This is where most people are first told they have chronic kidney disease and where lifestyle, diet, and blood pressure management make the biggest measurable difference. CKD Tracker logs sodium, potassium, and phosphorus alongside the standard labs so that small diet adjustments become visible in lab trends within weeks, not years.
Stage 4 CKD. eGFR between 15 and 29. Tracking gets denser: potassium and phosphorus matter more, fluid balance starts to matter, anemia and bone-mineral disease often appear, and conversations about dialysis or transplant typically begin. CKD Tracker supports that complexity by letting you log hemoglobin, calcium, parathyroid hormone, and bicarbonate alongside the core labs.
Stage 5 CKD and dialysis. eGFR below 15. Either dialysis (hemodialysis or peritoneal) or a transplant is on the horizon. CKD Tracker supports dialysis-specific logging: pre- and post-dialysis weight, ultrafiltration volume, blood pressure around treatment, vascular access checks, and PD exchange logs. Daily fluid restriction tracking becomes central, and every meal, every drink, and every weight matters.
Transplant follow-up. After a kidney transplant, the focus shifts to immunosuppressant adherence, lab surveillance, and infection awareness. CKD Tracker handles tacrolimus or cyclosporine levels, donor-specific antibody (DSA) results, and creatinine trend post-transplant alongside the standard labs you have already been logging.
Underlying causes. Diabetic kidney disease, hypertensive nephrosclerosis, IgA nephropathy, polycystic kidney disease, and lupus nephritis are common roots. CKD Tracker does not try to diagnose — it lets you tag your underlying condition so you can log the related markers (HbA1c for diabetic CKD, urine protein for glomerular diseases, cyst-related pain for PKD) without bolting on a second app.
What to Track for Chronic Kidney Disease
These are the fields that turn a kidney-disease log from a notebook of vibes into a record your nephrologist can actually use. Track whichever apply to your stage and care plan.
eGFR and creatinine (with each lab draw)
BUN, albumin, and urine ACR
Potassium, phosphorus, calcium, bicarbonate
Blood pressure (morning and evening)
Daily weight (same time, same scale)
Fluid intake against daily limit
Sodium, potassium, phosphorus, protein per meal
Medications (binders, ACE/ARB, diuretics, ESA)
Hemoglobin, ferritin, transferrin saturation
PTH and vitamin D for bone-mineral health
Symptoms (fatigue, swelling, itching, nausea)
Dialysis sessions or PD exchanges (if applicable)
Tracking Tips for People Living with CKD
Practical advice from people managing chronic kidney disease. None of this is medical advice; it is structural advice for your log.
Take Blood Pressure at the Same Time
Pick a morning slot before coffee or medication and an evening slot before dinner. CKD Tracker averages your readings weekly so an outlier from a stressful afternoon does not skew the trend you actually need to act on.
Weigh Yourself Daily
Same scale, same time, after using the bathroom and before breakfast. A two-pound jump in a single day is the kind of fluid-retention signal CKD Tracker is built to catch before swelling, breathlessness, or a midnight ER visit.
Log Meals, Not Just Symptoms
Sodium, potassium, and phosphorus are invisible until labs come back. Logging meals in the moment closes that gap. Within two weeks most users can predict roughly which meals will move which lab values.
Anchor Phosphate Binders to Meals
Binders only work taken with food. Schedule them inside the meal reminder, not as separate alarms. CKD Tracker pairs binder doses with meal logs so you can see at a glance whether you actually took them when it counted.
Front-Load Your Fluid Allowance
If you have a fluid restriction, the most common failure is running out before evening medications. Spread the allowance across the day with a small reserve for nighttime pills. CKD Tracker shows remaining fluid budget in real time.
Photograph Your Lab Reports
After every blood draw, snap the report and attach it inside CKD Tracker. The raw values get plotted on the trend, and the original PDF stays available if you switch nephrologists or need to escalate to a specialist.
Flag NSAIDs and Contrast
Ibuprofen, naproxen, and iodinated contrast imaging can each acutely worsen kidney function. Log them any time they are unavoidable so a sudden eGFR dip is not a mystery. Always confirm with your nephrologist before any contrast study.
Bring the Export to Every Visit
A 90-day PDF beats a memory test. Hand it to your nephrologist at every appointment and your visits stop being “how have you been” and start being “here is the trend we should discuss.” That is the conversation that changes outcomes.
How It Works
Four steps from install to a record your nephrologist can actually use.
Set Your CKD Stage and Targets
Pick your CKD stage (1 through 5, dialysis, or transplant) and enter the lab targets, blood pressure goal, fluid limit, and renal-diet ranges your nephrologist set for you. CKD Tracker preloads typical ranges if you do not have them yet so you have a starting point.
Log Daily Basics
Morning and evening blood pressure, daily weight, fluid intake, and meals. Each entry takes under 15 seconds. CKD Tracker timestamps everything and updates your dashboard so today’s status — on target or off — is always visible.
Enter Labs and Symptoms
After every blood draw, type the key values (eGFR, creatinine, potassium, phosphorus, hemoglobin) and attach the lab PDF. Log symptoms like fatigue, swelling, itching, or nausea as they appear so the timeline tells the whole story, not just numbers.
Review and Share
Before every appointment, open the summary view: blood pressure averages, weight trend, fluid balance, lab trajectory, renal-diet adherence, and medication adherence. Export a clean PDF for your nephrologist or keep it private.
