Why Muscular Workout Log could be just the workout app you are looking for: - Over 100 exercises included + create your own exercises - Choose from pre-configured workout programs & routines - and create your own routines - Charts: Visually analyse your workout activity and follow your progress for specific exercises - Widgets: Keep an eye on your workout metrics with a small, medium and large widget - Our app is gym-proof: do the exercises in any order you want. Replace, reorder on the go. - Tired of inflexible workout apps that force you to set the weight unit to either LB or KG for all exercises? With Muscular you can toggle the weight unit during workout for each exercise separately. - Metrics bar: Easily compare last time's metrics or your personal records with current weights, reps, duration etc. - More precise workout volume calculation for bodyweight exercises: Each bodyweight exercise has a bodyweight percentage (e.g. you push about 64% of your bodyweight each standard pushup) - Bodyweight exercises with assisted mode enabled allow switching from weighted to assisted for each set individually! E.g. start off with weighted pull-ups, then do sets without weights and finish with assisted pull-ups. - Auto-adjusting rest timer: change the rest timer duration on the go for each exercise individually. Or set a fixed rest time. - Double set mode: Always keeps the set number even and the rest time only fires every second set! Great for single-side exercises like one-arm rows, cable shoulder raises etc. or for drop sets. - Health Kit integration: Completed workouts are written to the Apple Fitness app if you grant us access. Details below* - Siri shortcuts: easily add your routines to Siri shortcuts and e.g. say "Start Back and Biceps" to start your custom routine workout. Try out the app without paying a single cent. When you are ready for more, pay once for life-time access! No subscription! * For health kit integration to work properly, we need to read the following data: body mass, active energy, heart rate (if available through Apple Watch). And we will write the following data to the Apple Fitness app: workouts, body mass and active energy. Active energy and (if available) heart rate help us to calculate burnt calories. Body mass is required to calculate resistance for bodyweight exercises more accurately. We do not read or write any other health related data. We do not share your health or workout data with third parties.

The call

The clearest difference is ads: Kreas at none against Muscular's shown. Kreas also leads on update cadence (every 2 weeks vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.
