VibeUnits vs PrepTracker
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.

- Converts mils RMS, peak-peak, 0-peak
- Converts microns RMS, peak-peak, 0-peak
- Converts ips RMS, peak-peak, 0-peak
- Converts mm/s RMS, peak-peak, 0-peak
- Converts G's RMS, peak-peak, 0-peak
- Converts m/s² RMS, peak-peak, 0-peak
- Supports D-V-A conversions for sinusoidal waves

This screenshot shows the text fields empty and — check this — "0 of 10 Screenshots." Your 8 iPhone shots showed as uploaded earlier; either this view is a different device-size well (scroll up to check the iPhone 6.3" section still shows 8), or they didn't persist. Verify before anything else — and after uploading media or filling fields, hit Save (top right) before navigating away; this console loses unsaved work. Here's everything paste-ready for the fields on this page: Promotional Text: Free, private, offline. See how many days your household could last and what to stock next. Widgets, outage mode, and go-bag checklists included. Description: PrepTracker helps your household stay quietly ready for power cuts, storms, and everyday disruptions. It is free, it works fully offline, and your data stays on your phone. No account. No ads. No tracking. SEE YOUR RUNWAY Log the water, food, and supplies you already have. PrepTracker shows how many days your household could last, what runs out first, and the next thing worth adding. Targets scale to your household, including kids and pets. BE READY FOR OUTAGES The power runway estimates how long your batteries and power stations can carry the essentials. When the power goes out, Outage Mode puts food safety timers, a flashlight, and your plan on one calm screen, with a Live Activity countdown on your Lock Screen. GO-BAGS THAT BUILD THEMSELVES Start from ready-made templates for a 72-hour bag, car kit, kids' bag, pet bag, and documents pouch, then check items off as you pack. Your readiness score updates as you go. KEEP THE IMPORTANT THINGS CLOSE Store emergency contacts, medical cards, and evacuation routes. Lock sensitive notes in a vault protected by Face ID. Add widgets to your Home Screen and Lock Screen so your runway is always one glance away. PRIVATE BY DESIGN Everything lives on your device. There is no login, no cloud account, and nothing to sync. If you choose the optional weekly email digest, your device sends only a short summary you can read before it goes. CALM, NOT ALARMING PrepTracker is built for ordinary households, not bunkers. Regional starter packs suggest sensible supplies for where you live, and the app nudges you toward small, steady progress. PrepTracker offers general preparedness guidance only, not professional emergency advice. In an emergency, follow instructions from local authorities. A product of Cubed Holdings LLC.

Verdict
The clearest difference is iOS requirement: VibeUnits at 10.0 against PrepTracker's 15.5. On price, ads, in-app purchases and monetization model there is nothing between them.
