From the founder

Why I made this.

Hey there,

Since 2016 (when I got saved) I've been studying the Bible. Many highlights saved in my Bible app of choice. Some notes in said Bible app. Some in Apple Notes. And some somewhere on a piece of paper I don't have anymore. It was all scattered.

I've tried many Bible study apps. None helped me remember and feed my curiosity.

So I made one. Harvous knows scripture, looks up words I'm curious about, and stays out of the way when I want to write.

It's named after Proverbs 25:2 — "It is the glory of God to conceal a matter; to search out a matter is the glory of kings." Studying the Bible is searching. Harvous is the place where the search settles into something you can come back to.

Right now it's available on web with Mac, iPad, and iPhone apps coming later. You can add scripture in 11 English translations, see automatic built-in dictionary suggestions, and highlight what stands out to you.

FAQ

Potentially Asked Questions

What exactly is Harvous?

Harvous is a space to save, organize, and find your Bible study notes. Think of it as a home for all those notes from reading the Bible, listening to sermons, and attending study groups—organized automatically so you can actually make sense then, now, and later.

Is Harvous a Bible app?

Harvous is a notes app designed to complement your Bible reading experience. Use it alongside your favorite Bible reader app or physical Bible. When you type a scripture reference, that scripture text is automatically generated as a note for you. We currently support BSB, ESV, KJV, NKJV, NIV, NLT, NET, NASB 1995, CSB, AMP, and MSG.

What devices is Harvous compatible with?

Harvous works on any device with a modern web browser. For a better mobile experience on your tablet or phone you can “Add to Home Screen” and it becomes more like an app.

How much does it cost?

Harvous is free for personal Bible study — unlimited notes, scripture pills, highlights, threads, and the rest of the core app. See pricing for what’s included today and optional paid add-ons: Review, Shared Spaces, and Challenges.

What's a thread?

A thread is a collection of related notes. Instead of organizing by date or book, threads let you group thoughts by topic or theme or however you want. This is your breadcrumb of study.

Who can see my notes?

Just you, unless you want to share it with others. If you decide to share there will be a unique sharable link that is created.

Do I need to be a Christian to use Harvous?

Nah. Harvous works for anyone exploring the Bible — whether you’re curious, new to faith, or been studying for years. Your questions and thoughts are welcome, wherever you are.

Can I use Harvous for church or small groups?

At this time there are no group features but paid group features will be coming later.

Does Harvous use AI?

This is a hot topic. We have strong stances on where and how AI should be used in Bible study. Right now there are no AI features for the core note taking experience. However, we do have exciting plans for paid features in the future. Think Duolingo for Bible study ;)

Can I export my notes?

Absolutely! Just go to Settings > My Data and you’ll see export options.

Does Harvous work offline?

Yes.

Who is Derek Castelli?

Hey, I’m Derek! I’m a Christian, husband, and dad to 2 dogs and 2 cats. By day I make websites full-time. In my freetime I work on Harvous (which I made primarily for me) and God-willing I will work on this full-time one day to then work on it for many years to come.

My journey with God started in 2016. It took a friend of mine asking me if I go to church and then a pastor and the church to open my eyes, ears, and heart. After 3 visits I got saved and since then my life has been one wild ride. 5 years later I’d get a calling from God centered around Proverbs 25:2 to build a tool with my creativity that only I knew how to make.

How do I contact support?

One last thing

Harvous only helps if you actually use it — so consider this your nudge.

I'm not trying to build the biggest Bible app out there. Just one I'd actually want to open every morning, that remembers what I've studied so I'm not starting from scratch each time.

If it helps even one of your study sessions stick a little longer, it'll have done its job.

Try it free, and if you ever want to talk shop or scripture, email me at derek@harvous.com.
