About

GrainLog

Features
Read full description

GrainLog is a woodworker's shop journal: every project with its photos and hours, a cut list that does the board feet math for you, the finish recipe that actually worked, and the lumber rack by species. Start a project and log shop time as you go, twenty minutes or a whole Saturday. Enter the parts in inches and GrainLog totals exact board feet, then tells you what to actually buy: thickness snapped to real yard sizes (4/4, 5/4, 8/4) with your waste allowance built in. Walk into the lumber yard with a number, not a guess. Finishes stop being guesswork too. Keep the schedules that worked, rate them, and flag the ones you would never repeat. Six proven starter recipes are included, from foolproof wipe-on poly to food safe board butter. Link a recipe to a build and it prints right in the build notes. WHAT YOU GET - Project log: photos, status from planning to done, and hours per session - Cut list builder: exact board feet per part, buy totals with waste, parts checked off at the saw - Finish recipes: prep, steps, coats, dry times, ratings, and would-use-again verdicts - Lumber stash: your rack by species with board feet, cost, and drying state - Wood species guide: hardness, working notes, and finishing tips for 12 shop staples - Tool wish list: priorities, honest prices, and what is left to buy - Stats: shop time by week, board feet by species, where the hours went - Build notes PDF and cut list CSV export for the shop binder - Syncs across iPhone, iPad, and Mac with iCloud FREE AND LIFETIME Free includes 3 full projects with cut lists, sessions, and photos, plus the recipe book, the species guide, the lumber rack, and the tool list. Lifetime is a single purchase that unlocks unlimited projects and cut lists plus the PDF and CSV exports, forever. No subscription. PRIVATE BY DESIGN No account of ours, no analytics, no tracking. Your workshop lives on your device and in your private iCloud, which we cannot read. Settings has a Delete All My Data control that erases everything from your device and your iCloud. PRICING GrainLog Pro is a one time Lifetime purchase of $14.99 USD. Payment is charged to your Apple Account at confirmation of purchase.

Verdict

The call

The clearest difference is in-app purchases: FlashInvaders at none against GrainLog's 1. FlashInvaders also leads on iOS requirement (12.0 vs 26.0). On price, ads and device support there is nothing between them.
