An app studio building small, exact tools — offline by default, no accounts, no tracking.
Each Boltworks app does one job and does it precisely. It works without a signal, keeps your data on your device, and asks for nothing — no login, no ads, no permissions. For people who need a reliable number, not another subscription.
Tell it what you want to run — it tells you exactly what to buy: battery bank, solar panels, charge controller, inverter and wire. Accurate. Offline. No account. Built for van, RV, cabin and boat off-grid systems, lithium-ready.
The whole app runs on your device. No network calls, no servers waiting on the other end. It works where you actually are.
No account, no analytics, no tracking, no ad SDKs. We don't collect anything, because the app never sends anything anywhere.
Every result shows the formula and assumptions behind it. Transparency is the trust — you can check our math.
A single, one-time unlock. No subscriptions, no upsells, no nagging. Buy it, own it.
