Every laser project starts with the same question: what settings do I use? Laser Library answers it. Log a test once — the machine, the material, the power, speed, and passes, plus a photo of how it turned out — and you never have to guess at those numbers again. BUILT AROUND YOUR WORKSHOP • Machines — track every laser you own: type, wattage, lens, work area, and the software you drive it with. • Materials — save the stock you actually buy, down to species, coating, thickness, and supplier. • Tests — record power, speed, passes, frequency, line interval, focus offset, air assist and more, then rate how the result came out. SEE WHAT ACTUALLY WORKED Photograph the finished cut or engrave and attach it to the entry. Six months later, the picture tells you more than the numbers do. FIND IT AGAIN IN SECONDS Search and filter your whole library by machine, material, operation, or result. Put two tests side by side to see exactly which setting made the difference. SHARE WITH OTHER MAKERS Publish a dialed-in setting to the community, or browse what other makers have already proven on the same material. Save anything useful straight into your own library. ON IPHONE AND IPAD Sign in and your library syncs across iPhone and iPad. Signing in is optional — the app works offline and keeps everything on your device until you decide otherwise. PURCHASES One purchase unlocks Laser Library Pro: unlimited machines, more photos per test, and no ads. Prefer to keep it simple? Remove Ads on its own for less. Neither is a subscription. Works with diode, CO2, fiber, MOPA, and UV lasers.

Verdict

The call
