Why I went from a range notebook to a private digital log

I used a paper notebook in my range bag for years. Date, firearm, ammunition, distance, weather, the load that worked, the load that didn’t. Pen and a small notebook. Nothing electronic, nothing connected to anything.

It was a deliberate choice. I didn’t trust apps with my firearms list. The notebook was the workaround — analog, on me, off the network.

Then one day I tried to find a session from the previous spring. I thought it was a Wednesday. I thought I’d shot the precision rifle, with the load I was working up, at 600 yards. The answer was in the notebook somewhere. I just couldn’t find it.

I flipped through pages for forty-five minutes and gave up. The data was there. I just couldn’t get to it.

That was the moment.

What the notebook was good at

I want to be honest about this part. The notebook is not a bad system. It does some things well:

• In the moment. The notebook is fast at the bench. Time to next entry: ten seconds.
• Unfiltered. Whatever you write goes in. No required fields, no schema, no app prompting you for the wind-direction column.
• No batteries. It works in the cold, in the rain, when your phone is at the truck, when you’re away from cell signal.
• No surveillance. Nobody else can see it. It is exactly as private as where you keep it.

For the moment-of-capture part of the job, the notebook is a fine tool. I still keep one in the bag for that reason. The problem is the rest of the job.

What it couldn’t do

The list is short, but every item is a thing I actually wanted from a tracking system and didn’t have:

• Tell me my round counts. I had years of session entries. I could not tell you within a thousand rounds how many had gone through any specific firearm — and I’m being generous. The “answer” was an estimate. For service intervals, that’s not enough. (I wrote a longer take on this in How to track rounds fired (without a spreadsheet or app you don’t trust).)
• Surface a last-shot date. Same problem. I’d flip pages looking for the last entry that mentioned a particular firearm, find what I thought was the last one, then second-guess myself.
• Find a session from six months ago. The thing that started this whole project. The notebook is sequential and ungrepable. You either remember roughly when, or you don’t.
• Survive being lost. Forgotten in a range bag. Left in the rain. Walked away by anyone with hands.

The notebook is good at remembering. It is bad at telling you what it remembers. After a few years, the data becomes write-only. Every entry is real, and almost none of it is retrievable.

Why I didn’t trust apps

I had looked at the apps. There were several. The reasons I passed on every one of them:

• Venture-backed. A company with outside investors has a job — return capital — and that job is rarely served by leaving a small subscription business alone forever. Some version of “make the data more valuable” is on the eventual roadmap. Not because anyone is malicious. Because that’s what the incentive structure asks for.
• Ad-supported. Free apps have to make money somewhere. With firearms data, somewhere is going to involve more parties than I want involved.
• “AI-powered” everything. I do not want an LLM somewhere training on my session notes. I don’t want a vendor sending my entries to a third-party AI service for “smart suggestions.” None of this requires malice; it requires a normal product roadmap and a normal AI vendor relationship.
• Acquisition risk. Even if the founders today are perfectly aligned with shooters, the next owners may not be. Data outlives the original company’s intent.
• Breach risk. Any large centralized database of firearms inventories is a target. Not theoretically — actually. The shortest list of databases that contain my list is the safest list.

None of these are conspiracy theories. They are normal incentive structures, normal product evolution, normal corporate finance. They are the reasons most existing apps were not going to be the right home for my data — even ones with current privacy policies I liked.

So I stayed on the notebook. For a long time.

What I built instead

After the lost-session episode, I tried the spreadsheet route for a while. That had its own problems — multi-barrel formulas were brittle, my “private” file was syncing to iCloud without my full attention, and entering a session on a phone was miserable. (I wrote that one up too: Shooting log spreadsheet templates: what works, what breaks.)

I’m a software developer. I had the tools to build the thing I actually wanted. So I did.

Shooting Log Pro is the result. Its shape comes directly from the list above:

• The job the notebook couldn’t do — round counts that update themselves, per-firearm and per-barrel; last-shot dates surfaced automatically; searchable session history; out-of-service tracking; per-firearm session reports.
• The privacy posture I didn’t see anywhere else — no third-party analytics on user data, no error tracking with user data, no AI services, no ad networks, no data warehouse, hard delete on account close, full CSV export anytime, US-hosted.
• The structural choices that keep it that way — indie. Bootstrapped. No outside investors. No exit plan. One person runs it. That’s me. I’m on the About page with a name, a photo, and an email address.
• A written continuity commitment — if I ever shut down or am acquired, you get 60 days of notice, full export the entire time, hard delete at shutdown if you don’t export, and your data is never sold as part of any deal. The longer version is in What I do — and don’t do — with your firearms data.

It is the system I’d been wanting for a long time, built so the version of me who didn’t trust apps for good reasons would actually be willing to use it.

Who this is for

If you keep a range notebook and that’s working for you — keep it. The notebook is a real tool. Use Shooting Log Pro for the part the notebook is bad at: telling you what’s in it. Many of the shooters I imagine using this product will keep both.

If you keep a spreadsheet and you’re tired of the maintenance, or you’ve realized your “private” spreadsheet is replicated to a third-party server you didn’t fully consent to — this is the alternative.

If you’ve been telling yourself you should start tracking and you haven’t — start with one session. Two minutes. The trial doesn’t ask for a credit card. You’ll have something on day one that you didn’t have before: a round count that updates itself, a session you can find again, and a record you actually own.

This isn’t for everyone. It is not for FFLs, gun stores, ranges managing rentals, or anyone whose use case is commercial inventory. It is for individual shooters who want to know what they’ve fired, when, and through what — without giving the answer to anyone else.

If that’s you, the 14-day trial is the next step. Start anywhere — log a single session — and see if it’s better than what you have. The notebook (and the spreadsheet) will still be right where you left them.
