DotPass Passwords vs Blackout Math.Power Calculator

DotPass is an app for generating and retrieving passwords. You enter a graphical pattern in a dot grid and a plain text seed word (like "facebook", "reddit", "work" or whatever makes sense to you), and the app then generates a password based on this unique combination you can use for this account. As long as you remember the pattern you've chosen and the seed word for each password, you can get your passwords back any time you need it. But unlike other solutions your passwords are never stored or sent anywhere, so there is no password information on your device or online that can be stolen or lost and you don't need any network access. The idea is that a graphic pattern and plain seed words are much easier to remember than strong passwords. Any change in either pattern or seed word results in a completely different password. So you can decide on one pattern and reuse together with different seed words for different accounts, and get good random-looking different passwords for each account. - All generated passwords contain numbers, uppercase and lowercase letters to fulfill common password criteria. - Select either 9 or 18 character passwords - Once generated you can just tap to copy the password, if you've got Continuity set up you can also paste it in on your mac. - For security app resets and clears any copied passwords from the pasteboard after use. There is also a macOS version of DotPass available in the Mac App Store. So you can easily access the same passwords on your mac as well. To make these passwords secure you must of course keep your pattern and seed words secret, just as you would with your password. If you are worried about someone looking over your shoulder you can use the extra privacy features in the app to hide the pattern, seed or password after entry. For added security the app automatically resets if left in the background more than a minute. For a more in-depth security discussion go to https://www.lostminds.com/dotpass

Blackout Math Power Calculator for Real Blackouts When power is unstable, guessing becomes expensive. Wrong battery choices, unrealistic expectations, and incorrect calculations lead to wasted money and failed setups. Blackout Math is not a generic calculator. It is a practical decision-making tool designed for real power outages — helping you understand how long your power will actually last and which battery truly fits your needs. No ideal numbers. No marketing promises. Only realistic calculations for real conditions. Know how long your power will last Configure your battery type, capacity, and voltage — and Blackout Math will: • calculate usable energy in Wh and kWh • account for safe depth of discharge for each battery chemistry • factor in inverter efficiency and real losses • show realistic operating limits No overestimation. No dangerous assumptions. See the real impact of your devices Add any household appliances — lights, routers, laptops, refrigerators, boilers, heaters. Specify power, quantity, and usage time, and the app will instantly: • calculate real energy consumption • show each device’s impact on total load • determine actual runtime — not theoretical values You’ll know exactly when power runs out. Real charging time — not guesses Blackout Math considers battery chemistry and charging limits to provide: • accurate charging time estimates • warnings about unsafe charging currents • charging power based on voltage × amperage • state-of-charge calculations from any starting level No unrealistic “0 to 100%” promises. Complex energy concepts, explained clearly Blackout Math helps you understand: • why usable energy is always lower than nominal • what depth of discharge really means • how inverter efficiency affects runtime • how to choose batteries for real-world usage No engineering background required. Built for clarity and speed Clean inputs, instant calculations, intuitive sliders, and light & dark themes — designed for fast, stress-free decisions when time matters. Perfect for: • planning during blackouts • choosing portable power stations (EcoFlow, Bluetti, Anker) • estimating backup time for apartments and houses • selecting batteries for solar and backup systems • analyzing and optimizing home energy usage Blackout Math is built for real conditions. It helps you avoid costly mistakes and make confident decisions — even under pressure. Less guessing. More certainty. Better energy decisions.
