No ads. No subscription. No gadget to buy. Set your phone in the rig, see which corner is low and how much to raise — then get on with your day. Most leveling apps bury the answer under a wall of decimals — or a banner ad. FlatPad shows a top-down footprint of your RV, pools shade toward the corner that's low, and saves strong color for one thing: the instant all four corners sit level. NO ADS. NO SUBSCRIPTION. NO HARDWARE. • No banner ads — not even in the free version • No subscription — leveling is infrequent, so you pay once or not at all • No $150 Bluetooth box to mount and pair — your phone already has the sensors • Runs entirely on-device — no account, no sign-in ONE CLEAR THING ON SCREEN • A top-down plan of your trailer — the bubble drifts to the high side, a raise badge points at the low corner • Not a single number to parse • Set the phone down either way; the rig image rotates to match • Turns green the moment you're level ACCURATE CALIBRATION — FREE Every phone rests a hair off-flat because of the camera bump. FlatPad's two-read flip method measures that lean and subtracts it, so your readings are true — not off by a degree. It's the accuracy feature rivals gate behind a paywall. Here it's free. • Two quick reads, spun 180° — takes about 20 seconds • Works on any flat surface; it needn't be level • Haptic confirmation when each read lands BLOCK-HEIGHT MATH See exactly how much to raise each corner, in inches or centimeters. Heights are worked out from your rig's footprint, so calibration ends with a quick optional step to set it — and if you skip it, FlatPad tells you which default it's using instead of quietly guessing. A RIG FOR EACH RV Got more than one? Save a rig for each — its leveling method, its size, and a name you'll recognize — then pick the one you're parked in from the Visual or Audio tab. No re-entering dimensions every time you swap vehicles. • Each rig remembers its own leveling method and footprint • Switch in one tap, right where you're leveling • Name them anything — "Airstream", "the toy hauler", "Dad's fifth wheel" • One rig is free; keeping a library of them is Pro EVERYTHING YOU NEED TO LEVEL IS FREE Visual leveling, flip-method calibration, and block-height math never cost a thing — and never show an ad. FLATPAD PRO — $9.99 ONCE, NOT A SUBSCRIPTION Pro matches gear that costs $150 in hardware. One lifetime unlock, shared across all your devices: • Voice guidance — FlatPad speaks each move ("raise rear left, about an inch and a half") and waits until the rig settles before it talks again. Level from the jack stands without ever looking at the screen. • Apple Watch companion — set the phone in the rig and walk to the jack; your wrist shows the corner to raise and how much, turning green the instant you're level. No extra hardware to buy. • More leveling modes — level-by-side for paired jacks, and a stabilizer-only mode that squares you side-to-side first, then the front jack (independent-corner leveling is free) • A rig for every RV — save each vehicle's leveling method and size, and switch between them as you park (one rig is free) • Manual dark & light theme override Park it. Glance. Level.
