Apps and Websites Every Pediatrician and Pediatric Resident Should Bookmark

A practical, opinionated list of pediatric websites and apps I actually find useful, including a few limitations I wish someone had told me earlier.

Pediatrics is full of moments where you need the right answer quickly.

A neonate weighs 2.8 kg and you need to check the dose. A child has croup and you want to confirm the severity score. A parent asks about development. A PG exam topic suddenly appears during rounds. You know you have read it somewhere, but you do not have twenty minutes to search five different books.

This is where good tools help.

Not because apps replace textbooks. They do not. Nelson is still Nelson. Guidelines are still guidelines. Senior advice still matters. But the right website or app can save time, reduce mistakes, and help you think more clearly when the ward is busy.

Here are the pediatric resources I would actually keep bookmarked.

Quick list first

• UpToDate — best quick clinical reference if you have access.
• HealthyChildren.org — best for learning how to explain things to parents.
• AAP Pediatrics and Red Book Online — useful for updated pediatric guidance and infectious disease references.
• WHO IMCI — essential for community pediatrics and South Asian practice.
• WHO Child Growth Standards — growth charts and nutrition assessment.
• PedsCases — best free case-based pediatric learning.
• MDCalc — fast clinical calculators.
• PediaHelper — pediatric calculators, drug dosing tools, and PubMed-backed Ask Evidence.
• Epocrates — drug reference and interaction checking.
• Medscape app — decent free backup reference.
• PocketMed AI — offline on-device clinical AI assistant.

1. UpToDate

UpToDate is still the first thing many clinicians open when they want a quick, structured answer.

Where it helps:

• Common pediatric conditions
• Initial approach to symptoms
• Pediatric drug dosing summaries
• Management algorithms
• Updates in treatment recommendations

What I like: It is fast and usually gives you a practical answer without making you read a full chapter. For a resident, that matters.

What I do not like: It is expensive if you do not have institutional access. It can also make you lazy if you use it as your only source. It gives answers, but it does not replace building concepts from textbooks and guidelines.

Best use: Quick clinical orientation before reading deeper.

2. HealthyChildren.org

HealthyChildren.org is written for parents by the American Academy of Pediatrics.

That may sound less useful for doctors, but it is actually one of the reasons I like it. Pediatricians spend a lot of time explaining things. Fever. Vaccines. Feeding. Development. Screen time. Sleep. Constipation. Safety. Parents do not need textbook paragraphs. They need clear language.

Where it helps:

• Anticipatory guidance
• Developmental milestones
• Vaccine counseling
• Common parent questions
• OPD communication

What I like: It teaches you how to explain medicine in normal language.

What I do not like: It is not meant for detailed clinical management. Use it for communication, not as your final treatment reference.

Best use: Preparing simple, parent-friendly explanations.

3. AAP Pediatrics and Red Book Online

The AAP Pediatrics journal and Red Book Online are worth knowing even if you do not open them every day.

Pediatrics is useful for updated clinical articles, policy statements, and research. Red Book is especially important for pediatric infectious diseases.

Where they help:

• Infectious disease questions
• Vaccine-related details
• Updated AAP policy statements
• Exam references
• When you need a more authoritative source than a quick summary

What I like: Red Book is one of those references you may not need daily, but when you need it, you really need it.

What I do not like: Some content needs subscription access. Also, AAP guidance is US-focused, so you still need to adapt to local guidelines and availability.

Best use: Pediatric infectious disease and updated guidance.

4. WHO IMCI

WHO IMCI is not glamorous, but it is important.

For Nepal and much of South Asia, IMCI remains very relevant. It is practical, structured, and designed for real-world settings where resources may be limited.

Where it helps:

• Fever
• Cough and difficulty breathing
• Diarrhea and dehydration
• Malnutrition
• Danger signs
• Community pediatrics
• Exam preparation

What I like: It forces you to think in a structured way. Assess, classify, treat, counsel, follow up.

What I do not like: It can feel too algorithmic if you are trying to understand deeper pathophysiology. It is a framework, not the whole of pediatrics.

Best use: Community pediatrics, outpatient triage, and exam revision.

5. WHO Child Growth Standards

WHO Child Growth Standards are essential if you are assessing growth and nutrition.

You should be comfortable with weight-for-age, length/height-for-age, weight-for-length or weight-for-height, BMI-for-age, Z-scores, and severe acute malnutrition classification.

What I like: Growth charts make nutrition assessment visual and objective.

What I do not like: People often use them mechanically without looking at the child. The chart is important, but so is edema, appetite, illness, feeding history, and the full clinical picture.

Best use: Nutrition assessment and growth monitoring.

6. PedsCases

PedsCases is one of the best free pediatric learning websites I know.

It is case-based, clean, and very resident-friendly. Many topics include podcasts and notes, which makes it useful during commutes or low-energy revision.

Where it helps:

• Clinical reasoning
• Common pediatric presentations
• Communication scenarios
• Emergency topics
• Exam-style thinking

What I like: It feels like learning from a case discussion, not reading a dry list.

What I do not like: It is Canadian, so some management pathways and health-system details may not directly match Nepal. Still, the reasoning is very useful.

Best use: Building clinical reasoning when you do not want to open a heavy textbook.

7. MDCalc

MDCalc is one of the fastest ways to use clinical calculators without searching through notes.

Pediatric tools worth knowing include Pediatric Glasgow Coma Scale, Westley Croup Score, PECARN head injury rule, dehydration scores, and other emergency or risk-stratification tools.

What I like: It is quick, clean, and works well on mobile.

What I do not like: Calculators can create false confidence. If you do not understand when a score applies, the number can mislead you.

Best use: Confirming scores you already understand.

8. PediaHelper

PediaHelper is one of my own projects, so obviously I am biased. But I built it because I felt this gap myself.

Most medical tools are either too broad, too adult-focused, too slow, or not designed for the kind of quick pediatric questions residents ask during duty.

PediaHelper is meant to be a pediatric toolkit in one place.

Current useful parts:

• Pediatric drug dosage library
• Clinical calculators
• Neonatal and pediatric dosing tools
• Quick reference pages
• Ask Evidence, designed to answer pediatric clinical questions using PubMed-backed evidence

What I like: It is built specifically with pediatric residents in mind. Not “medicine in general,” but the kind of questions that come up in pediatrics.

What I do not like: It is still evolving. I would not want anyone to blindly prescribe from any tool, including mine. Drug doses still need verification with local protocol, pharmacy, and clinical context.

Best use: Quick pediatric calculation, dose review, and evidence orientation before reading deeper.

9. Epocrates

Epocrates is a useful drug reference and interaction checker.

Where it helps:

• Drug interactions
• Contraindications
• Basic dosing review
• Safety warnings
• Quick lookup during duty

What I like: It is fast and the interface is less painful than many drug apps.

What I do not like: For pediatric dosing, especially neonates and high-risk drugs, I still prefer cross-checking with a pediatric-specific reference or local pharmacy protocol.

Best use: Drug interaction checks and quick medication review.

10. Medscape

Medscape is not perfect, but it remains a useful free backup app.

Where it helps:

• Drug monographs
• Disease summaries
• Interaction checker
• Medical news
• Quick reference when you do not have access to paid tools

What I like: It is free and broad.

What I do not like: It is broad in a way that can feel shallow. I use it as a backup, not as my main pediatric reference.

Best use: Free secondary reference.

11. PocketMed AI

PocketMed AI is another tool I built.

The idea is simple: an offline, on-device clinical AI assistant for situations where internet access is unreliable or where you do not want every question going to a cloud server.

Why I built it:

• Hospital internet is not always reliable
• Many useful AI tools need constant connectivity
• Clinical questions can be sensitive
• Doctors in low-resource settings still need fast support

What I like: It works offline and keeps queries on the device. That is the whole point.

What I do not like: Small offline models have limits. They can help with thinking, but they are not a final authority. You still need references and judgment.

Best use: Quick offline clinical thinking, differential generation, and revision support when internet access is poor.

How I would actually use these during residency

• Need a quick clinical overview? UpToDate.
• Need to explain something to parents? HealthyChildren.org.
• Need infectious disease detail? Red Book, if available.
• Need community pediatrics or exam basics? WHO IMCI.
• Need growth and nutrition assessment? WHO growth standards.
• Need case-based revision? PedsCases.
• Need a clinical score? MDCalc.
• Need pediatric-specific tools quickly? PediaHelper.
• Need drug interaction checking? Epocrates or Medscape.
• Need offline AI help? PocketMed AI.

For exam preparation

For MD, DM, fellowship, MECEE-PG, or similar exams, these tools can support your preparation, but they should not replace proper reading.

• PedsCases is good for clinical reasoning.
• WHO IMCI is good for community pediatrics and public health-style questions.
• MDCalc helps you remember practical scoring systems.
• UpToDate helps clarify updated management.
• PediaHelper Ask Evidence can help orient you around a clinical question before reading papers.

Use apps to reinforce knowledge, not to avoid learning it.

Final thoughts

The best tool is the one you actually use correctly.

A beautiful app is useless if it is slow during rounds. A long guideline is useless if you cannot find the relevant section when you need it. A calculator is dangerous if you do not know when it applies.

For me, a good pediatric tool should be fast, clear, easy to search, honest about uncertainty, useful at the bedside, and grounded in evidence or standard references.

That is the standard I try to use when choosing resources, and it is also the standard I am trying to build toward with PediaHelper and PocketMed AI.

If you know a pediatric app or website that is genuinely useful, especially for South Asian practice, send it my way. I will keep updating this list.
