Hey Product Hunt 👋
I'm the maker of Energy Check-In — happy to answer any questions here.
The idea came from a frustrating realization: I had numerous productivity apps telling me what to do and when to do it, but none of them told me anything about when I actually work well. So I spent some time reading through Reddit productivity communities before writing a line of code — trying to understand what people were genuinely struggling with, not what I assumed they needed.
The pattern that kept surfacing: people know their schedule. They don't know their energy. And the gap between the two is where most productivity systems quietly fall apart.
Energy Check-In is my attempt at closing that gap. A 5-second check-in every 90 minutes builds a personal heatmap showing your peak hours, your energy by activity type, and how your mood tracks alongside your energy. It's not another task manager or focus timer — it's just data about yourself that you didn't have before.
The product is free — unlimited check-ins, 7-day heatmap, no credit card. Pro adds full history, weekly reports, and pattern insights.
Would love to hear what patterns you discover in your own data. And if anything feels off or missing, tell me here — I'm building this in public and every piece of feedback shapes what gets built next.

One thing that would really make this shine is adding a quick calendar integration so I can see how my energy patterns line up with actual meetings and deep work blocks. Right now I can track when I peak, but having it overlay on my calendar would help me actually protect those hours and reshedule draining tasks into low energy windows.

@tolga245243 Thanks! I really like this idea. Calendar integration is actually high on my list because it would connect subjective energy with what was happening during the day, making the insights much more actionable.
I can also imagine it going a step further—not just showing meetings, but identifying which types of events tend to boost or drain your energy. Definitely something I'd love to explore in a future version.
Report
Love the focus on tracking actual energy rather than just time. One thing that would make this way more useful for me: a quick weekly recap that suggests one small tweak to my schedule based on my top and bottom energy windows. Right now I can see the data but turning it into a concrete action takes extra thinking.

@aysunzhanyeue Thanks! I like that idea a lot. The good news is that this is very close to what the Insights Report is meant to do. Once you've collected enough check-ins, it starts looking for patterns in your data and suggests practical improvements based on your energy trends. I definitely think there's room to make those recommendations even more concrete with a weekly "try this next week" summary.

the peak-hours visualization looks really thoughtful, especially how it ties patterns back to your own logged data instead of leaning on generic circadian tropes. nice restraint in the design.

@bulemqtmo Thank you! That was actually one of the core ideas behind the app. There are plenty of generic productivity recommendations out there, but I wanted to build something based on your data rather than assumptions.
I'm glad the design came across that way. My goal was to keep it simple and let the patterns emerge naturally as more check-ins are collected.
Report
Logged my energy for a week and it nailed that my focus crashes right after lunch every single day, something I never tracked before. Wish it had a desktop version though.

The onboarding asking how you actually feel rather than just dumping a chart on you is a really thoughtful touch. Makes the whole experience feel like it’s about you from the first tap.

@oykuener77260 Thank you! I'm really glad that stood out to you because that was intentional. I wanted the app to feel personal from the very beginning, not like another dashboard asking you to fill in data before giving anything back.
