How Blip Actually Works: A Feature Walkthrough from the Developer
Howdy, I'm Mike. I built Blip with my wife Dr. Silppa, who writes all the clinical content and practice questions. She's the dental brain. I'm the one who obsesses over look and feel.
I wanted to write this post because we get asked a lot about what Blip actually does. And I think the best way to explain it is just to walk through the whole thing - what each feature is, what it looks like when you use it, and why we built it that way.
What is Blip?
Blip is a focused INBDE question bank built for speed and weak-spot targeting. Not a comprehensive study platform with videos, flashcards, and AI chatbots. Just a fast, clean quiz engine designed around how we think people should study for board exams. High-volume question practice with intelligent review.
Everything in the app is built around one idea: your study time should be spent answering questions, not managing your study plan.
What's the Quiz Builder?
The Quiz Builder is the home screen. It's where every session starts, and it's designed so you can go from opening the app to answering your first question in less than 10 seconds.
You pick a mode, how many questions you want, and any filters you care about. That's it.
Three modes. Study mode is relaxed. You can navigate freely and review as you go. Speed Challenge puts you under the clock and scores you on both accuracy and pace. Smart Review builds your session automatically based on your history. More on both of those below.
Filters. You can narrow by subject, difficulty, and tag status. Subjects are dynamic. As Silppa adds questions in new areas, those subjects just show up automatically.
Timer options. Off, per-question countdown, or total quiz timer. Speed Challenge has its own built-in timer.
Feedback modes. Instant (quick color flash after each answer, then you keep moving), end of quiz (everything at the end), or off. Speed Challenge always uses instant feedback because the whole point is momentum.
What is Speed Challenge?
This is my favorite mode, and I think it's genuinely different from what other platforms call "timed mode."
Most INBDE prep tools with a timer option just put a countdown clock on a regular quiz. You still manually advance between questions. Speed isn't scored. It's the same experience with a clock in the corner.
Speed Challenge is built around the idea that speed is a skill you train, not just a thing you measure. The timer counts up, auto-advance keeps you moving, and your performance is scored as a composite of both accuracy and pace. We call it a Speed Score.
The benchmark is real INBDE pacing. The actual exam gives you roughly 90 seconds per question across 500 questions over two days. Speed Challenge is calibrated to that. If you're consistently drilling at or below that pace with high accuracy, you're going to feel way more comfortable on exam day.
You get a Speed Score at the end of every session, and we track your personal bests, both overall and per subject. So you can watch yourself getting faster at pharmacology specifically, or see your overall pace improving week over week.
The point is, the INBDE is a stamina test as much as a knowledge test. Speed Challenge trains you for the pacing, not just the content.
What is Smart Review?
Smart Review solves what Silppa calls "the 20-minute problem". Students finish a session and then spend 20 minutes deciding what to study next. Smart Review eliminates that entirely.
It looks at your entire history - what you've tagged as needs work, what you've gotten wrong, how long it's been since you've seen certain questions, which subjects you're weakest in, and what you haven't seen yet - and it prioritizes accordingly. The questions that need your attention most urgently show up first.
There's a spaced repetition engine under the hood. Get a question right and it gets pushed further out, you won't see it again for a while. Get it wrong and it comes back soon. The system is always adjusting based on how you're actually performing, not on a static schedule.
The result is that every Smart Review session is different, and every session is focused on exactly what you need. No decisions, no planning, just drilling your actual weak spots.
How does the tagging system work?
Every question has a tag: untagged (default), green (confident), or red (needs work). You set these yourself during a quiz or from the results screen.
This is simple on purpose. Silppa's approach during her own INBDE prep was to tag everything she got wrong as red, everything she nailed as green, and leave the rest as-is. Then she'd build sessions from just the reds. That workflow is baked into Blip.
You can filter the Quiz Builder however you need. Your tags also feed directly into Smart Review. A red tag is the strongest signal that a question needs to come back.
Keyboard shortcuts: G for green, R for red, U for grey (undo). You can retag without breaking your flow.
How does difficulty work?
We don't manually label questions as easy, medium, or hard. That would be subjective and it wouldn't scale.
Instead, difficulty is computed from how users actually perform. If a question has a low accuracy rate across everyone who's attempted it, it's hard. High accuracy rate, it's easy. In the middle, it's medium. This updates continuously as more people use the platform, so difficulty is always current and always based on real user data.
You can filter by difficulty in the Quiz Builder. If you want a session of only hard questions in your weakest subject, you can build that.
What does the analytics dashboard show you?
Analytics is designed to answer one question: am I getting better?
You get accuracy over time, a breakdown by subject showing where you're strong and where you're not, tag distribution per subject, and an exam readiness view that combines your accuracy, coverage, and trend direction into a simple status per subject: strong, developing, weak, or not started.
There's also a peer comparison layer. For each subject, you can see how your accuracy stacks up against the Blip average. It's essentially anonymous aggregate data to give you a sense of where you stand relative to other students prepping for the same exam.
What do you get for free?
50 questions to start, then 10 more every day. Study mode only. Full explanations on every question. Tagging works. No credit card required.
The free tier is designed to be genuinely useful, not a crippled demo. 50 questions is enough to get a real feel for the question quality, build some tag history, and start seeing your accuracy patterns. The daily recharge means you can keep using it indefinitely, it's just a tad slower.
By the time you've used your welcome questions, you've got tagged questions, accuracy data by subject, and a history that Smart Review can build from. Upgrading to Pro feels like unlocking more of something you're already using.
What's the design philosophy?
I come from a design background, and there are some decisions I made that might seem small but I think matter a lot when you're doing hundreds of questions in a sitting.
Dark mode is the default. Most students study at night. The light theme is there if you want it, but dark is the primary experience.
Keyboard shortcuts are first-class. 1 through 4 to select an answer, arrow keys to navigate, F to flag, G/R/U for tags. When you're doing 200 questions in a session, the difference between clicking and pressing a key adds up.
Everything is fast. Quiz generation, answer feedback, page transitions - we optimize aggressively. If something feels sluggish, that's a bug, not a tradeoff (please let us know in Discord!). The whole pitch of Blip is that you're training at pace. The app needs to keep up with you.
Gamification is quiet. There are daily streaks, XP, levels, and badges, but they're almost invisible unless you're looking for them. Nothing crazy, no pop-ups, no push notifications. If you like that stuff, it's there. If you don't, it'll never bother you.
No bloat. You configure, you drill, you review. You get better. That's it.
Why did we build this?
Silppa went through the INBDE herself. She used the major platforms. She spent money she didn't need to spend. And when she reflected on what actually helped her pass, it was the practice questions. Specifically, doing a lot of them fast and letting her weak spots guide what she reviewed next.
None of the platforms she used were really built for that. They all had questions, but the experience was slow, the review was manual, and speed was never treated as something you train.
We built Blip to be the tool she wished she had. A focused drill engine that's fast, clean, and smart enough to handle the study planning for you. That's the whole idea. Everything in the app serves it.
If you want to try it, the free tier is right here. You get a bunch of free questions. And please hop in Discord, we love chatting with you all!
