So you want a tracker for feng shui work
Feng shui analysis involves a lot of moving parts—orientations, flying stars, personal kua numbers, room layouts, date selection. Keeping track of all of that by hand is where most people fall apart. I started doing this manually in 2014 and burned through three notebooks before switching to a digital tracker system. That's when I realized the real problem isn't the calculation itself, it's the record-keeping. The most straightforward approach I've found is combining a basic spreadsheet with a feng shui compass app and a simple project log. I use Google Sheets for the tracking side because it syncs across devices and I can pull up a reading from my phone while standing in a client's doorway. The tracker itself just needs columns for: property address, date of reading, facing direction (in degrees), sector breakdown, individual star placements per palace, occupant details, recommendations given, and follow-up notes. That's it. Nothing fancy. I built a template that auto-fills the nine palace grid once you enter the facing degree. You plug in 273.5 degrees and the spreadsheet spits out the current period star chart. It took me about an hour to set up and saves me roughly twenty minutes per reading now. The initial investment isn't small but it compounds fast if you're doing more than a couple readings a month.
One edge case that almost broke my system: working with properties that have rotated floor plans or non-rectangular shapes. I had a client in Portland with a triangular lot where the compass reading at the front door didn't align with the main living space. The facing direction from the street was roughly 40 degrees off from what made sense for the actual interior layout. I ended up taking two separate readings—one at the entry and one from the center of the primary living area—and weighted them based on which zone received the most daily occupancy. The client's feedback over six months suggested the second reading was the more accurate predictor of what was happening in the space. I now always note both readings in the tracker when a property has irregular geometry. There are dedicated apps that claim to handle this automatically. Most of them are fine for basic flying star charts but they struggle with composite directions and certain school variations. I tested five different options last year and ended up going back to my spreadsheet because the margin of error on the apps was noticeable when I cross-referenced against manual calculations. One app consistently misread 350 to 360 degree crossings, which sounds minor until you're analyzing a property right on that cusp. A few things nobody tells you about feng shui tracking:
First, the period matters more than you'd expect. We're currently in Period 9 (2024-2043) and any tracker or app you use needs to be set to calculate with the correct period. I've seen readings go completely wrong because someone ran a Period 8 chart on a 2025 property. It's an easy mistake and a costly one if you're giving advice based on it. Second, temperature and magnetic interference will mess up your compass readings more than you think. I had a reading in a downtown Chicago condo where the elevator shaft next to the unit was throwing off the compass by about eight degrees. The tracker showed one thing and the actual energy flow suggested something different. I learned to take three readings at different points in the entryway and average them rather than trusting a single snapshot. If you're just starting out and don't want to build a spreadsheet from scratch, there are free templates floating around on feng shui forums. Download one, customize it, and test it against at least five properties before you trust it on a paying client. My template has been through probably two hundred readings over seven years and I still tweak it occasionally when I run into a new edge case.

The bottom line is that the tool doesn't matter as much as the discipline of recording everything. I can look back at a reading from three years ago and see exactly what I recommended, what the stars were doing, and whether the advice held up. That retrospective view is worth more than any app feature. I'd rather have a clunky tracker that I actually use consistently than a polished one that sits untouched because it's too complicated to set up. If you want a starting point, search for "feng shui flying star tracker spreadsheet" and you'll find several options. Pick one that matches your preferred school of feng shui and modify it until it fits your workflow. The best system is the one you'll actually maintain.
