5 best apps for tracking bone health during perimenopause
No app can scan your bones. What the right apps can do is help you stay consistent with the two things that actually move the needle during perimenopause: progressive strength training and enough protein, calcium, and vitamin D to support it.
Quick answer
There is no single "bone density tracker" app, because bone density is a medical measurement, not a phone sensor reading. Instead, the best approach is pairing a strength app that tracks progressive load with a nutrition app that tracks the nutrients bone remodeling depends on.
Fortify is the strongest pick for tracking progressive strength training built for perimenopause. Proto is the strongest pick for fast, protein-first tracking without turning nutrition into a second job. StrengthLog and Hevy are solid general lifting logs if you already know your program. Cronometer is best if you want deeper micronutrient detail, including calcium and vitamin D.

Why bone health tracking is really two problems
Bone health during perimenopause is shaped by two things you can actually influence day to day: mechanical loading from strength training, and the raw materials bone needs to remodel itself, mainly protein, calcium, and vitamin D. Estrogen decline during perimenopause speeds up bone loss, which makes consistency in both areas matter more than it did in your 20s and 30s.
No consumer app measures bone density directly. That requires a DEXA scan. What a good app can do is make it easy to see whether you are actually progressing your strength training load over months, and whether your protein intake is consistently where it needs to be, with a separate detailed tracker to confirm calcium and vitamin D if you want that level of detail. Tracking those things consistently is the practical version of "tracking bone health" that is available outside a clinic.
The 5 best apps for tracking bone health during perimenopause
1. Fortify — best for tracking progressive strength training
Fortify is built specifically for women in midlife, with structured strength plans that progress load over time rather than handing you a random workout each session. For bone health, this matters because the loading needs to increase gradually to keep providing a stimulus, and Fortify makes that progression visible instead of something you have to calculate yourself.
Best for: Women who want their strength training load
tracked and progressed automatically, with joint-friendly options built
in.
Price: Free trial, then subscription.
2. Proto — best for fast protein tracking
Bone remodeling depends partly on consistent protein intake, alongside calcium and vitamin D from food or supplements. Proto's protein-first logging makes it fast to keep an eye on whether you are actually hitting your protein target day to day, without the friction of a full calorie-tracking workflow. Proto tracks protein, calories, and fiber, not micronutrients, so pair it with Cronometer or a supplement routine if you want calcium and vitamin D tracked in detail.
Best for: Fast, low-friction protein tracking alongside
a strength app, without heavy daily logging.
Price: Free trial, then subscription.
3. StrengthLog — best free option for tracking load over time
StrengthLog logs sets, reps, and weight in detail and is genuinely usable on the free tier. For bone health purposes, the value is in the history: you can look back over months and confirm your working weights are actually trending up, which is the real signal that your training is providing a bone-loading stimulus.
Best for: Women who already know their program and want
detailed free logging to confirm progressive overload.
Price: Free core app, paid premium for extra programs.
4. Hevy — best for simple consistency tracking
Hevy's strength is in how easy it makes logging a workout and seeing a clean progress graph afterward. For bone health, consistency over months matters more than any single session, and Hevy's visual history makes it easy to spot when a routine has quietly lapsed.
Best for: Women who want a low-friction way to confirm
they are training consistently over time.
Price: Free core app, paid Pro tier for extras.
5. Cronometer — best for detailed calcium and vitamin D tracking
Cronometer's full micronutrient breakdown covers calcium and vitamin D specifically, alongside protein and calories. It is more detailed and slower to log than Proto, which suits people who want to verify their micronutrient intake precisely rather than track a single headline number.
Best for: Women who want to confirm calcium and vitamin D
intake in detail, not just protein.
Price: Free tier, paid Gold subscription.
How to pair a strength app with a nutrition app
The simplest setup is one app for training and one for nutrition. Use Fortify (or StrengthLog or Hevy) to confirm your strength training load is progressing two to four times a week, and use Proto to keep protein in view daily. If calcium and vitamin D tracking matters most to you, use Cronometer instead, since it covers those in detail and Proto doesn't. Trying to do everything in a single all-in-one app usually means one side gets neglected.

Takeaway
No app tracks bone density directly, but the right apps can track what actually protects it during perimenopause: progressive strength training and enough protein, calcium, and vitamin D. Fortify covers the strength side, and Proto makes protein tracking fast. Add Cronometer if you want calcium and vitamin D tracked in detail too.
Please note: Fortify and Proto do not provide medical advice. Always consult a qualified healthcare professional about bone health, including whether a DEXA scan is appropriate for you.
Frequently asked questions
Can a phone app actually track bone density?
No. Bone density itself can only be measured with a DEXA scan ordered by a doctor. What apps can track are the habits that support bone health: progressive strength training, weight-bearing exercise, and calcium, protein, and vitamin D intake.
What should I track for bone health during perimenopause?
The two biggest levers are consistent progressive strength training and adequate protein, calcium, and vitamin D. A strength app that tracks load over time, plus a protein tracker like Proto and a detailed nutrient tracker like Cronometer for calcium and vitamin D, covers both.
Do I need two separate apps for bone health?
Most people do, since strength apps and nutrition apps solve different problems. Fortify for progressive strength training and Proto for fast protein tracking is a practical pairing. Add Cronometer alongside if you also want calcium and vitamin D tracked in detail, since Proto tracks protein, calories, and fiber but not micronutrients.
How much strength training is needed for bone health?
Two to four sessions per week focused on progressive loading is a well-supported range. Bone responds to mechanical stress that increases over time, which is why tracking your working weights matters more than just tracking that you worked out.
