Body Scan Apps Compared: TandemFit, MeThreeSixty & ZOZOFIT

Exploring body scan apps? Compare TandemFit, MeThreeSixty, and ZOZOFIT for tracking measurements and understanding progress beyond the scale.

Body measurements are one part of your progress. The workouts you complete are another. When you want to look back at several weeks of training, it helps to have both available instead of reviewing a scan on its own.

TandemFit lets you save body measurements and review your workout history in the same app. MeThreeSixty and ZOZOFIT document phone-based scanning and visual comparison tools. Here is how their measurement features compare, and how TandemFit puts body measurements alongside the training you actually do.

Track body measurements alongside your workouts

A scan can give you a measurement to revisit. Your workout history shows what you were doing during that time. TandemFit keeps both in one place, so your progress review can include your training as well as your measurements.

Imagine you have been following a lifting routine for several weeks. You want to check your measurements, but you also want to see which sessions you completed and how consistently you followed the routine. In TandemFit, you can review your body measurements and your logged workouts without maintaining a separate workout app for that part of the review.

That is the practical benefit for someone who already tracks their training: body measurements become another part of the same record. You can look beyond a single scan and revisit the work you have been putting in.

Include food and cardio in your progress review

TandemFit also includes meal and macro logging and outdoor GPS recording for running, walking and cycling. Alongside your measurements, you can review the meals and workouts you recorded over the same period.

That broader record is the difference this comparison highlights. Scan history shows previous measurements; TandemFit also gives you your logged training and nutrition to look back on. Having them together provides context without assuming that one workout or meal caused a body change.

See progress beyond the scale

See body-measurement trends alongside your workouts to understand progress beyond the scale. TandemFit combines photo-based measurement estimates with your training history, giving you more context than a scan alone.

Photo-based measurements are estimates, so small differences between scans may not reflect a meaningful body change.

How MeThreeSixty and ZOZOFIT show scan progress

MeThreeSixty documents phone-based capture, body measurements, and side-by-side scan comparisons. Premium includes full scan history and additional metrics. Those tools organize the changes recorded across scans.

ZOZOFIT documents body measurements, side-by-side comparisons, color visuals, and trend graphs. Its Base plan includes scans, logging, and trend graphs. Both app-only scanning and scanning with ZOZOSUIT are documented options.

Those scan features describe what you can capture and compare. TandemFit also gives you a workout history to refer to during that review. For someone using measurements to follow their training progress, having both records available is a useful part of the choice.

Free scans with measurements included

The free Athlete account includes a monthly body-scan allowance, with available measurement estimates included rather than sold as a separate upgrade. That gives you a way to follow changes over time alongside your workouts without committing to a separate scanning subscription. MeThreeSixty lists full scan history and additional health metrics among its Premium benefits.

More context for your training questions

TandemFit also includes AI trainer chat for questions about your recorded workouts and nutrition. Claude and ChatGPT connections offer another way to discuss shared fitness records in an assistant you already use. These conversations add context from logged activity; they do not establish why a measurement changed. Assistant account and connection requirements apply.

Why TandemFit is our overall pick

TandemFit is our best overall pick for people who want body measurements alongside their training and nutrition. MeThreeSixty and ZOZOFIT offer scan comparison tools, while TandemFit also includes workout logging, meals and macros, and GPS cardio. The recommendation is about that broader fitness toolkit, not a claim that its scans are more accurate.
