u/Prudent_Setting_1866

I got tired of workout apps with social feeds, AI coaches, and rigid templates. Just wanted something fast, that worked like a paper log but didn't suck on a phone. So I built one.

It's called My Workout Logs: https://myworkoutlogs.lamdera.app

It's a PWA — open it in iPhone Safari, hit Share → Add to Home Screen, and it runs like a regular app. No App Store, no signup. You can tap "Preview sample data" to look around first.

A few things that make it different:

No presets. It starts as a blank page so the log fits your training, not someone else's program.
Handles more than barbell stuff — weighted pull-ups/dips, bodyweight, assisted, static holds, supersets, cardio, complex movements.
Your data is yours. Full CSV export, JSON backup, and recovery codes to move between devices. No email or account required.

It's in alpha. A stable version is coming soon, and it will always be free — no subs, no paywalls, no ads.

If you try it, I'd love to hear what feels missing or annoying. That feedback is what drives what gets built next.

For barbell lifts, most apps use formulas like Epley, Brzycki, Lander, O’Conner, etc. But for weighted pull-ups/dips, the estimates vary a lot depending on the formula and how much bodyweight you count as moving load.

Example:

Bodyweight: 91 kg
Bodyweight coefficient: 0.95
Moving bodyweight: 86 kg
Added weight: +40 kg
Reps: 6

Using total moving load with Epley:

total moving load = (91 * 0.95) + 40 = 126 kg
estimated total 1RM = 126 * (1 + 6/30) = 151 kg
estimated added 1RM = 151 - 86 = +65 kg

But in practice, my actual 1RM was closer to +55-57 kg.

The Kensui weighted pull-up/dip calculator seems to use a more conservative rep-percentage table, where 6 reps is about 89% of 1RM:

estimated total 1RM = total moving load * (100 / 89)
estimated added 1RM = ((86 + 40) * (100 / 89)) - 86
estimated added 1RM ≈ +56 kg

That gives a much closer estimate.

So I’m curious:

What formula do you use to estimate weighted pull-up/dip 1RMs?
Do you use Epley, Brzycki, RPE tables, percentage tables, or something else?
Do you count full bodyweight, partial bodyweight, or just added weight?
Do you find different formulas work better for pull-ups vs dips?
What rep range do you trust most for estimating 1RM?

I’m especially interested in what experienced streetlifters actually use for programming, not just what generic gym calculators say.

Made a minimalist iPhone workout log because every other app felt bloated

What formula do you use to estimate weighted pull-up/dip 1RMs?
