Proflame Connect Plus vs ZenLevel

This is the official app to control all fireplaces with embedded Proflame control

ZenLevel turns your iPhone into a precision inclinometer with the calm, deliberate feel of a real machinist's instrument. Built for builders, DIYers, photographers, woodworkers, and anyone who needs something perfectly level, perfectly plumb, or at exactly the right slope. FOUR MEASUREMENT MODES SURFACE — Lay your iPhone flat on a countertop, shelf, or picture frame. The two-axis bubble instrument shows the exact inclination, with digits that roll smoothly between values like a laboratory dial. When you find true level, the interface shifts to a calm, luminous green. PLUMB — Press the back of your iPhone against a vertical surface to check whether it is truly vertical. A tall bubble tube rises and falls with the wall's deviation, and a "check position" warning tells you when the phone is too flat for an accurate reading. CALIBRATE — Every sensor drifts. Place your phone on a surface you trust, wait for the stability meter, and tap ZERO OUT. Offsets persist across launches, and Reset calibration restores factory defaults at any time. HISTORY — Save any measurement to a log grouped by day. Tap an entry to see its details, edit its note, or delete it. HOLD THE READING Measuring under a shelf or behind a cabinet? Tap HOLD to freeze the reading, then take your iPhone out and read it — or save it — at your leisure. Tap RELEASE to go live again. SLOPE UNITS Show every reading in degrees, percent grade, millimetres per metre, or inches per foot. Rise-over-run units make drains, ramps, patios, decks, and gutters easy: a quarter inch per foot is simply 0.25 in/ft. Saved measurements follow your chosen unit and keep the original angle alongside. LANDSCAPE PRECISION MODE Rotate your iPhone to landscape and SURFACE becomes a long horizontal bubble vial for checking frames, shelf edges, and countertops along their length. A tipping indicator helps you keep the phone upright to avoid projection errors.
