We build Trackr, so you would expect this comparison to end with "download the app." It mostly does, but not entirely, because spreadsheets are genuinely good at things no fitness app will ever match. If you have been tracking your weight or your lifts in Google Sheets for two years and it works, some of what follows will confirm you were right.
The real question is narrower than "which tool is better." It is: which tool survives daily use, at the gym or half-asleep on the scale, on a day when motivation is gone? That is where the two options separate.
The short answer
A spreadsheet wins on flexibility and control. Trackr wins on friction, and friction is what decides whether you are still tracking in month three. If you love building systems and actually maintain them, keep the sheet. If your last three spreadsheets died quietly by week four, the app is the better bet.
Here are the honest details.
What a spreadsheet genuinely does better
Total flexibility
A spreadsheet tracks anything. Weight next to sleep hours next to your grocery budget, in whatever layout you invent. No app matches that, Trackr included. Trackr is built for fitness, meaning your bodyweight and photos plus your performance on specific lifts. If your tracking system spans your whole life, a sheet is the right container for the rest of it.
Custom analysis
Formulas are a superpower. Want a 7-day rolling average with a custom smoothing window, or a chart comparing your cut this year against last year? A spreadsheet does it exactly your way. Apps give you the views their designers chose. For most people those views are enough, but "most people" is not everyone.
A file you own forever
A spreadsheet is a file. You can back it up anywhere and open it in twenty years. That kind of portability is a real argument, and pretending otherwise would be dishonest. It is worth saying that Trackr keeps your data private and on your device rather than mining it, with cloud backup as a premium option, but a plain file you control is still the simplest form of ownership there is.
Where spreadsheets fall apart for daily tracking
Friction at the moment of entry
The whole game of daily tracking is the ten seconds after you step off the scale or finish a set. A spreadsheet on your phone means finding the file, waiting for it to load, pinching to zoom into the right cell, and fat-fingering the wrong row. Every one of those steps is a chance to say "I'll do it later." Later is where tracking habits go to die.
Photos do not fit in cells
Progress photos are the most convincing record of a body transformation, and spreadsheets have no good place for them. So photos end up in your camera roll while numbers live in the sheet, and six months later you are scrolling through hundreds of pictures trying to remember what you weighed in each one. Trackr closes that gap automatically: every progress photo is tagged with your current weight, so the before-and-after pairs build themselves.
No feedback loop
A sheet records. It does not respond. There is no streak telling you that you have logged twelve weeks straight, and nothing flags a personal record when your bench press finally moves. You can build some of that with formulas, and a few people do. Most never will, and the motivational loop is a bigger part of long-term consistency than it sounds.
What Trackr actually does
To keep the comparison concrete, here is what is in the app, without embellishment:
- Weight tracking over time, with your bodyweight history in one timeline.
- Progress photos tagged with your weight automatically, for real before-and-after comparisons.
- Exercise tracking with personal records, across lifts like bench press, squat, deadlift, and overhead press.
- Workout history and streaks, so consistency is visible at a glance.
- An overall score that rolls your consistency and progress, together with your achievements, into one number you can watch move.
It runs on iOS and Android, and your data stays private on your device. Cloud backup is there for premium users.
Notice what is missing from that list: macros, for example, or custom life metrics. Trackr does not try to be everything. If your tracking needs are mostly your weight and photos plus how your lifts are moving, that focus is a feature. If they are broader, see the verdict below.
The verdict, by person
Keep the spreadsheet if you track many unrelated things in one system, or you have an entrenched sheet with years of history that is still getting daily entries. Do not fix what works.
Use Trackr if your entries happen on your phone at the gym or on the scale, or your past attempts at tracking died from friction rather than lack of interest.
Use both if you want the app for daily capture and a spreadsheet for occasional deep analysis. Plenty of careful trackers run exactly this split: the phone does the logging, the sheet does the quarterly review.
FAQ
Can I use Trackr and a spreadsheet together?
Yes, and it is a sensible setup. Let the app handle the daily grind where friction matters most, then keep a sheet for any custom analysis or non-fitness metrics you care about. The mistake is making the spreadsheet the daily entry point when your entries happen away from a desk.
Is my data safe in an app compared to my own file?
That is a fair concern. Trackr stores your data privately on your device by default, and cloud backup is available as a premium feature rather than a silent default. A spreadsheet file you back up yourself is still the most direct form of control, so if that matters more to you than convenience, the sheet is a legitimate choice.
Is a spreadsheet enough for tracking weight loss?
Honestly, yes, if you use it. A weekly-averaged weight column and a chart cover the analytical side of a cut completely. The reason people fail with spreadsheet weight tracking is rarely the tool's math. It is the daily entry friction, and that is the one thing you should judge any tracking setup on before anything else.
If the friction argument sounds like your last three abandoned sheets, try Trackr on the App Store or Google Play and give it the same 30 days you gave the spreadsheet. Keep whichever one you are still using at the end.
