Plan Flow Meter vs Bubble Level

Original Purpose: As a developer, I once felt that most planning apps on the App Store were hard to use. They didn’t truly visualize goals and progress, nor did they effectively motivate users. After conducting surveys and research into what people really need, I created this app. The core idea is to make every check-in for your plan feel direct and rewarding, while also giving you great encouragement. I hope you find it both handy and enjoyable to use. Some Quick Tips: First, TOP plan is the most important one. You can set your most urgent plan as a TOP plan. To help you focus better, you can only have one TOP plan at a time. The app also offers a variety of widgets that you can freely combine and place on your home screen for quick access. Some of these widgets even include buttons for direct actions, so you can operate them without opening the app. Everything is designed with your needs in mind, and I believe you’ll make great use of it.

Turn your iPhone into a precision spirit level. Set it flat on any surface and the bubble tells you instantly whether that shelf, picture frame, table, or floor is truly level — no plastic tool required. Most phone levels stop at a single bubble. BubbleLevel is built for real projects: a 2D bullseye and single-axis vial, a pass/fail surface checker with an adjustable tolerance, a full angle finder that reads in degrees or percent grade, and a saved log so you can prove every reading later. Calibrate out a bent case or an uneven counter once, and every measurement stays true. WHAT YOU GET - A live bubble level with a 2D bullseye and single-axis vial for shelves, frames, and floors - Surface check that gives a clear PASS or FAIL against a tolerance you set - Angle finder and protractor reading degrees, percent grade, and roof pitch (rise-in-12) - Slope reference for drainage, gutters, ADA ramps, stair stringers, and roof pitches - Saved readings with timestamps so you can compare before-and-after or send proof - One-tap calibration that corrects a bent case or an uneven table for good PERFECT FOR - DIY homeowners hanging shelves, art, and mirrors dead straight - Carpenters and contractors checking level, plumb, and grade on site - Renovators leveling floors, counters, and appliances - Anyone who wants a true reading without carrying a bulky spirit level WHY NOT JUST USE A PLASTIC LEVEL A hardware-store level only tells you level or not — it cannot measure the exact angle, log the result, or fit in your pocket. BubbleLevel gives you the precise degree, a pass/fail verdict, and a saved history, all on the phone you already carry. PRIVACY Everything runs on your device. No account, no cloud, no tracking — your measurements never leave your phone, and the app works fully offline. FULL ACCESS The live bubble level is free to use. BubbleLevel Premium unlocks the surface checker, the angle finder, and your saved-reading history. Choose the plan that fits: Weekly, Yearly, or a one-time Lifetime purchase. Subscriptions auto-renew until cancelled; manage or cancel anytime in your App Store account settings. Level your next project the right way — download BubbleLevel and get a straight, true reading in seconds.
