Every legend keeps a log. Herculog (formerly MyLiftLog) is a weight lifting journal built on one principle: your training data belongs to you. No account. No subscription. No ads. No cloud. Open the app and lift — everything stays on your iPhone or iPad. LOG SETS IN SECONDS Name, sets, reps, weight — done. Auto-fill loads your last session's numbers for every exercise, so logging today's work takes a tap, not a form. Add RPE, warm-up flags, and notes when you want them; skip them when you don't. RUN GUIDED WORKOUT PLANS Build training plans or add ready-made programs from the Discover library — full-body, upper/lower, push pull legs, and more, with sets and reps already filled in. Then run each session set by set, checking off every set as you go. Leave the gym mid-workout and pick up right where you stopped. WATCH STRENGTH CLIMB Herculog computes estimated 1RM, total volume, and efficiency automatically from every set you log. Strength charts show your sets, daily max weight, and 1RM trend for every exercise, and personal records are tracked across 3-month, 6-month, 1-year, and lifetime windows — with a proper PR celebration when you earn one. SEE THE WHOLE MONTH Daily and monthly summaries put your consistency on the record: training days, total volume, sets, reps, streaks, and the awards you have earned. Spot patterns, keep the streak alive, stay honest. YOUR DATA IS YOURS — ACTUALLY • No account or sign-in, ever • No ads, no tracking, no analytics — the App Store privacy label reads "Data Not Collected" • Everything is stored on your device, nothing on our servers (there are no servers) • Export your complete history or your plans as CSV anytime — an open format any spreadsheet can read • Import plans the same way: build one at herculog.com/plan-builder, or have a coach send you one FORMERLY MYLIFTLOG Herculog is the new name for MyLiftLog — the same app from the same studio, updated in place. Your entire training history carries over with the update, because it never left your device in the first place. Free training guides — progressive overload, RPE, program templates, and a 1RM calculator — at herculog.com/guides. The iron is waiting. Start your log.

Verdict
The clearest difference is update cadence: Herculog at every 2 weeks against PHAT's every 14 months. PHAT's advantage is ratings volume (43 vs 8) and iOS requirement (11.3 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
