Version 1.0 Quick Fraction Calculator
Fraction math built for the shop floor — add, subtract, multiply, and divide in sixteenths without reaching for a pencil. Windows PC and Android from one Wood Solutions license.
Shop fractions
Sixteenths, thirty-seconds, and mixed numbers the way cabinetmakers think.
Two platforms
One $20 license key for Windows and Android.
Door Rail Calculator
Included on Windows — rail lengths from opening size and stile width.
What it does
A standalone utility for woodworkers who measure in fractions — not a general-purpose calculator with a fraction mode bolted on.
Mixed numbers
Work in feet, inches, and fractions the way you mark a stick in the shop.
Door Rail Calculator
Windows bonus tool — rail cut lengths from opening width and stile width. Not on Android.
Phone or PC
Same license on your shop computer and your phone — one purchase, two places to use it.

Beginner-proof
First time installing an app from a website?
Quick Fraction Calculator is not on Google Play — you download it directly from woodsolutions.com, the same way many independent shop apps are sold. These steps assume you have never sideloaded an app before.
- On your phone or tablet, open this page in Chrome (bookmark it — do not use random APK sites from a web search).
- Tap Download for Android when the APK is on this page — wait until the download finishes (Wi‑Fi helps on slower connections). Windows is available now.
- Open your downloads: pull down the notification and tap the file, or in Chrome tap ⋮ (menu) → Downloads →
QuickFractionCalculator-Android-1.0.apk. - If Android asks to Allow install from this source, turn it on for Chrome or Files — this is a one-time permission for apps not from the Play Store.
- If Google Play Protect warns you, tap More details → Install anyway (only when you downloaded from this page).
- Tap Install, then Open. On the purple screen tap Continue to app to start your 14-day trial — no purchase needed yet.
Updates: When a new version is released, download again from this page and install over the old app — your trial and license stay on the device. Same license as PC: one Creem purchase covers Windows and Android (within your activation limit). Stuck? Email sales@woodsolutions.com.
Purchase & licensing
$20 one-time — one license for Windows and Android up to your activation limit. 14-day free trial first; no purchase needed to start.
Downloads stay on this website — never from Creem.io. Creem.io handles payment as our Merchant of Record and emails your license key after checkout.
FAQ
- When can I download? Windows: now — use the download button above. Android: APK coming to this page. Questions: sales@woodsolutions.com.
- Which Windows? Windows 10 or 11, 64-bit. Not Mac.
- Which Android? Android 8+. Install only from this website — not Google Play.
- How much? $20 one-time — no subscription. Windows and Android share the same key.
- One purchase, two devices? Yes — one license key for PC and phone (see activation limit in your receipt).
- Where do I download? Always from this page — not from Creem.io and not from APK mirror sites.
- Why “Install unknown apps”? Android blocks non–Play Store installs by default. Allowing your browser or Files app once is normal for website downloads.
- Play Protect says the app is harmful? Common for apps outside Google Play. If you downloaded from woodsolutions.com/calculator, tap More details → Install anyway. See the beginner guide.
- SmartScreen (Windows)? More info → Run anyway if you trust this site.
- New phone or PC? Re-download here and enter the same license key.
