The app that tells you if your progress is working
Not another chart to interpret. A plain answer: on track, watch, or change something.
Short answer
ProgressLens is an app that tells you whether your progress is working. After each check-in, tap AI Analyze and it compares your photos and measurements with last time, says what changed, whether you’re losing fat or muscle, and gives one verdict (cut, lean bulk, recomp or maintain) with a weekly rate and how long to your target.
What “is it working?” really means
It’s three questions at once: Am I changing? Is it the right kind of change? Should I keep going or switch? The scale can’t answer any of them on its own. The Progress Report answers all three.
- Where you are. A body-fat range from your photos plus your tape measurements, with how sure it is.
- What changed. What looks different since your last check-in, area by area, next to your measured changes.
- Fat or muscle. A muscle-loss signal: are you losing fat, or losing muscle too? Built for cuts and GLP-1 journeys.
- What to do next. One verdict (cut, lean bulk, recomp or maintain), a weekly rate, and how long to your target.

Is it working
On track
Your waist is shrinking faster than your arms and shoulders: mostly fat loss.
What to do next
Cut
- Lose 0.7–1.1 lb a week
- About 12 weeks to around 12% body fat
- Next check-in in about two weeks, in the same place and light.
Estimates from your photos and measurements, not a medical assessment.
The signals it reads
| Signal | What it tells you |
|---|---|
| Waist vs weight | Losing fat, holding water, or recomping |
| Waist vs arms and shoulders | Fat loss or muscle loss |
| Matched photos, area by area | Where you look leaner or fuller |
| Weekly weight trend | Whether your rate fits your goal |
When to check
Check in weekly or every two weeks, same place and light, and analyze after each check-in. Real change shows over 4 to 12 weeks, so judge the trend across a few reports, not one.
FAQ
Frequently asked questions
Is there an app that tells me if my diet is working?
ProgressLens tells you whether your body is changing the way you want, from your photos and measurements: fat down, muscle kept, and on pace. It doesn’t track food.
How do I know if my workout program is working?
Over 8–12 weeks your arms, chest and shoulders hold or grow while your waist holds or drops, and matched photos look fuller. The Progress Report checks exactly that.
Will it tell me whether to bulk or cut?
Yes. Every Progress Report ends with one verdict, cut, lean bulk, recomp or maintain, based on your estimated body fat, your recent weight trend, your goal and your training experience, with a weekly rate and roughly how many weeks to your target.
Are my photos private?
Yes. They stay inside the app on your phone, not in your gallery or a cloud, and there’s no account. When you tap AI Analyze, only the photos you chose for that report are sent to the AI. They’re not stored and not used to train any AI.
