1RM Calculator vs HABIT

Estimate your one rep max (1RM) from any set. Enter the weight and reps you lifted, add RPE if you track it, and get your estimated max in seconds. FEATURES - 1RM calculator with optional RPE: reps left in the tank are counted, so 10 reps at RPE 7 is treated like a 13-rep max - Transparent formulas: your estimate is the average of Epley, Brzycki (up to 12 reps), Wathan, and Mayhew - Estimated rep maxes from 2 to 12 reps, each shown as a percentage of your 1RM, for planning working sets - Save results to your history by exercise, including your own custom exercises - Edit or backdate saved records - Export your history as CSV - kg or lbs, light or dark theme - 9 languages - No account needed: your records stay on your device PRO - 1RM progress chart for each exercise - Rep max table with your best recorded set for each rep count - No ads Pro is available as a monthly or yearly subscription, or as a one-time lifetime purchase. Subscriptions renew automatically until canceled in your store account settings. Your 1RM is an estimate, not a tested max. Estimates are most reliable at lower reps.

HABIT helps you interrupt unwanted habits with private, on-device planning, daily check-ins, and a growing forest that reflects your consistency. HOW IT WORKS Create an if-then plan for the habit you want to break. Name the trigger, choose a replacement action, and keep the plan ready when an urge shows up. THREE TREES FREE Your first 3 habits are free. Each habit gets its own tree, streak, check-in history, and progress. Swipe between trees and build a forest you can name. PRIVATE CHECK-INS Log each day with simple prompts for urge, mood, stress, slips, and notes. Your routine records stay on your device unless you explicitly choose context or attachments for Online Coach processing. TREE GROWTH AND STREAKS Your tree grows as your streak grows. Stage-up moments use animation and haptics so progress feels visible without turning the app into noise. SMART LOCAL REMINDERS HABIT avoids notification spam. By default it schedules a consolidated daily check-in reminder and, when needed, a streak-risk reminder before the day ends. HABIT COACH Use the local Coach for on-device guidance. When online Coach is enabled and you choose to use it, your message and only the context you select are processed through HABIT's authenticated service by Anthropic. HABIT Coach uses AI and is not a person, medical care, therapy, or crisis support. You can disable online processing in Settings and keep using the local Coach. HABIT PRO HABIT Pro expands your forest to 20 habit trees and adds advanced progress insights, forest personalization, and access to the online HABIT Coach subject to server-enforced monthly limits. Monthly and annual plans are available. Eligible new annual subscribers may receive a seven-day trial when the App Store confirms eligibility before purchase. PRIVACY FIRST After the age-and-region check, HABIT requires a verified account before opening the main app or processing a Pro purchase or restore. Your encrypted local repository is preserved while you create or verify the account; production sync remains disabled until its end-to-end encrypted recovery path is reviewed and verified. No ads. No ad-tech tracking. Purchases are verified through the app stores and RevenueCat. HABIT is a self-guided tracking and reflection tool. It is not a medical device, therapy, treatment program, or crisis service. It does not provide medical advice or diagnoses.
