Know every gram before you shoulder it.
PackyWacky is the gram-precise backpack weight analyzer, gear list calculator, and offline inventory journal built for hikers who treat base weight like a science, not a guess.
Four systems, one loadout.
Every tool in PackyWacky exists to answer one question honestly: what is actually on your back, and why.
Base Weight & Load Distribution Engine
The math behind every ultralight decision, worked out to the gram.
- Gram & Ounce Precision Calculator — split totals into Base Weight, Worn Weight, and Consumables.
- Category Weight Distribution Chart — see percentage allocation across Shelter, Sleep, Kitchen, Clothing, and Safety.
- Pack Center-of-Gravity Assistant — keep heavy items centered against your back on the trail.
Consumables & Trip Planner
Ration exactly what the trail demands — no more, no less.
- Water & Food Daily Ration Scaler — liters and calories per day, scaled to duration and terrain.
- Fuel Burn & Canister Weight Estimator — remaining gas, calculated from tare weight.
- Pack Load Wear & Tear Log — trail miles logged against boots, tents, pads, and filters.
Gear Inventory & Maintenance Vault
A private archive of every item you own, always ready to pack.
- Multi-Pack Loadout Builder — separate lists for overnighters, alpine treks, and summer UL trips.
- DWR & Waterproofing Scheduler — reminders for seam sealing, DWR spray, and filter swaps.
- High-Contrast Gear Photo Gallery — store specs, tags, and DIY modifications in detail.
Studio Analytics & Offline Access
Your gear history, and none of it leaving your pocket.
- Trail Portfolio Overview — compare pack weight trends across past expeditions.
- 100% Offline Access — calculate, adjust, and review deep in the backcountry, zero signal required.
- Private by Design — your inventory lives on your device, not a server somewhere.
Weigh it before you carry it.
Drag the sliders to sketch a loadout across five gear categories and watch your base weight, unit conversion, and distribution chart update live — the same math running inside the app.
Base Weight Builder
Base weight excludes worn items, food, water, and fuel — just what's in the pack.
About Us
We're a small crew of thru-hikers, gram-counters, and gear tinkerers who got tired of watching spreadsheets fall apart somewhere around mile forty. PackyWacky started as a dog-eared notebook full of scratched-out ounces and grew into the ultralight gear log we always wished existed — built by people who actually weigh their tent stakes.
Our mission is simple: strip the guesswork out of what goes on your back. Every gram you carry is a gram you feel on the ninth mile of an uphill switchback, so we built a tool that treats your loadout with the precision it deserves — no bloat, no clutter, no logging in just to check a base weight.
Inside PackyWacky, your gear finally gets sorted the way it should be — Base Weight separated from Worn Weight and Consumables, category breakdowns across Shelter, Sleep System, Kitchen, Clothing, and Safety, fuel canisters weighed down to the gram, and your entire inventory archived in a private vault that works with zero signal, deep in the backcountry.
Pack smarter, carry lighter, hike farther — that's PackyWacky, in one breath.
Privacy Policy
PackyWacky was designed offline-first, from the ground up. This policy exists mostly to confirm something reassuringly simple: there isn't much to say, because there isn't much happening behind the scenes. Your gear data stays on your device — full stop.
01 Information We Collect
PackyWacky is built to work entirely on your device. We do not collect, capture, or request any personal information, gear data, account credentials, location data, or usage analytics — from you or anyone else who installs the app. There are no sign-ups, no user profiles, and no hidden telemetry running in the background.
02 How We Use Information
Because nothing is collected, nothing is used. We don't analyze your pack lists, we don't study your hiking habits, and we don't sell, rent, trade, or share anything about you or your gear with advertisers, data brokers, or any other third party. Your loadout calculations stay exactly where you left them: on your phone.
03 Data Storage
Every gear entry, weight calculation, trip plan, maintenance reminder, and photo you add to your Gear Photo Gallery is stored locally on your device's own storage. PackyWacky does not operate a cloud server, remote database, or backup service of any kind — there is nothing to breach, because there is nothing stored anywhere but your pocket.
04 Third-Party Services
We do not integrate third-party analytics SDKs, advertising networks, crash-reporting trackers, or social media plugins. PackyWacky doesn't phone home. The app's core gram-counting, distribution charting, and inventory features have no network dependency — they're built to run fully offline in the backcountry, where there's no signal to send data over even if we wanted to.
05 Data Security
Since your gear vault, weight breakdowns, and photos never leave your device, the strongest security measure we can offer is the one already built into your phone — its native storage protections, passcode, and biometric lock. We recommend keeping your device's operating system current to benefit from those safeguards.
06 Children's Privacy
PackyWacky does not knowingly collect information from anyone, children included, because it does not collect information from anyone at all. The app has no chat features, no accounts, and no data-collection mechanisms of any kind, so it aligns naturally with the spirit of COPPA and similar child-privacy regulations worldwide.
07 Your Control
You are always in full control of your data because it never leaves your hands. There's no account to delete and no cloud copy to request removal of. Uninstalling the app permanently removes your gear inventory, photos, and saved calculations from your device — that's the entirety of the "data deletion" process.
08 Changes to This Policy
If PackyWacky's functionality ever changes in a way that affects this policy, we'll update this page and revise the Effective Date above. We encourage checking back occasionally, though given our offline-first design, meaningful changes here should be rare.
09 Contact
Questions about this Privacy Policy can be sent to privacy@packywackyapp.com. We'll get back to you directly, boots-on-the-ground style.
