SafeCycle Pro vs DumbLevel

SAFE CYCLE - THE PERIOD TRACKER THAT CAN'T SEE YOUR DATA SafeCycle is built from the ground up with one principle: your data never leaves your phone. Track your menstrual cycle with complete privacy and security. ZERO NETWORK ACCESS SafeCycle has no internet permissions. Your data physically cannot be sent anywhere - not to us, not to advertisers, not to anyone. This isn't a privacy promise. It's a technical guarantee. AES-256-GCM ENCRYPTION Your most sensitive data is encrypted with the same standard used by banks and governments. Even if someone gains physical access to your device, your health data stays protected. FACE ID / TOUCH ID Unlock SafeCycle with biometric authentication. Quick access for you, impenetrable barrier for everyone else. DUAL PIN SYSTEM Set a real PIN for your actual data and a stealth PIN that opens a fake calculator. When someone demands to see your phone, enter the stealth PIN - they'll see a working calculator, not your health tracker. STEALTH MODE CALCULATOR The calculator disguise isn't just cosmetic - it's a fully functional calculator. No one will ever know it's hiding your period tracker. SMART CYCLE PREDICTIONS Track your period and get intelligent predictions based on your unique cycle patterns. The more you log, the smarter it gets. DAILY SYMPTOM LOGGING Track mood, pain, energy, sleep, digestion, skin, and flow - all encrypted locally on your device.

It's just a level. DumbLevel is a bubble level for hanging shelves and pictures straight, plus a "What are we doing?" screen that does the layout math and hands you the marks. It's free. That's the whole deal. WHAT YOU ARE NOT GETTING • No subscription. Ever. • No account. No sign-in. • No ads. • No timer. It does not stop working after twenty seconds and ask for money. • No analytics. Nothing leaves your phone. THE LEVEL • Picks the mode by itself. Set the phone on its long edge for a level line, stand it upright for plumb, lay it flat for a two-axis bubble. • Reads to a tenth of a degree, in numbers big enough to read from a ladder. • Green, amber, red. Within two tenths of a degree is green. • Says which end is high, in words: RIGHT END HIGH. TOP LEANS LEFT. LEVEL. • Hold freezes the reading so you can lift the phone off the shelf and read it. • Sonar pings that speed up as you get close, and a coin chime when you hit level, so you can watch the shelf instead of the phone. Pings and chime, chime only, or muted. • Calibration that cancels the phone's own sensor bias. Capture, turn the phone end-for-end on the same spot, capture again. The true tilt cancels out and what is left is the phone's error, which is then subtracted from every reading. It is the same two-capture reversal that precision digital levels use, and it fixes the "my case has a bump on the back" problem. • The readout turns itself so up on screen is up in the room, whichever way you hold the phone. • Compared with the level built into the phone: tenths of a degree instead of whole degrees, plus hold, calibration and the hanging planner. WHAT ARE WE DOING? Pick the job: • One picture (or a mirror, a clock, a sign) • A row of frames • A grid of frames (a gallery wall) • Shelves, one or a stack of them • Hooks • Curtain rod Then a few plain questions, with the usual rule already filled in: pictures centered at 57 inches, eye level; 6 to 10 inches above a couch or a dresser; 2 to 3 inches between frames; a curtain rod 4 to 6 inches above the window and 4 to 6 inches past it on each side; coat hooks at 60 inches. Change any number you like. It does the math and hands you the marks: every one in inches from the end of the wall or the edge of the window, so you can read them straight off a tape. A to-scale drawing shows what you are about to hang. A walkthrough shows one mark at a time in giant numbers so you can make the marks with the phone in one hand and a pencil in the other. Print the sheet or share it as a PDF, tape it to the wall, then tap Level it and the level checks each one. Every job you measure is filed under Past projects, under the six tiles. Open the hallway you did last spring, see the same numbers, and hang the next frame to match. FINE PRINT DumbLevel reads to a tenth of a degree. Like every phone level it is only as good as the sensor inside the phone, so calibrate it before you trust it, and check anything that matters with a real level. It is a phone. iPhone only. Portrait only. Works with the screen off? No. It's a level, not a miracle.
