When Coach can turn a photo into a workout
INCREMNT is a strength-training app that helps athletes understand their training and decide what to do next. This week’s central change was giving Coach a safer boundary between discussing a workout and carrying out an explicit request to create, revise, save, or start one.

Make the first workout ready to use
INCREMNT is an iOS strength-training app that turns a goal, schedule, and available equipment into a workout plan. This week I tightened the handoff from that plan to a first workout that fits real life, starts honestly when no load history exists, and can travel across the phone and a Garmin companion without losing ownership.

Show the work before asking for trust
INCREMNT is an iOS strength-training app that turns what you log into a clearer next workout. This week, onboarding moved from describing that promise to proving it: the path now uses a person’s goal and training need to show credible research, real product behavior, and a plan that can survive an interrupted setup.

When training feedback survives the handoff
INCREMNT is an iOS strength-training app that helps athletes follow a plan and decide what to lift next. This week’s central work made training feedback durable across two important handoffs: a completed week can become a saved report that Coach can reopen, and effort recorded on Apple Watch is persisted before the phone clears the workout state.

From Ask Coach answers to reviewable training decisions
INCREMNT is a strength-training app that turns your training history into a plan you can actually follow.

Coach should remember what it can prove
INCREMNT is an iOS strength-training app that tells you what to lift next; this week its Coach became more useful between questions by carrying conversations forward, showing answers as they arrive, and keeping progress advice tied to evidence the app can actually verify.

The first workout should prove the plan
INCREMNT is an iOS strength-training app that turns your goals, experience, equipment, and schedule into a workout plan you can follow. This week I made the first workout part of that proof: onboarding now leads into a real, personalised logger with real history, recommendations, and a safe boundary around the sample data.

Proof you can follow
INCREMNT is an iOS strength-training app that builds a programme, guides each workout, and adapts what comes next; this week I worked on a simple product standard: important promises should come with a proof trail an athlete can inspect.

When intent survives the swap
INCREMNT is an iOS strength-training app that helps athletes follow a plan and decide what to lift next; this week’s work made that intent hold together when exercises are swapped, sets are interpreted, and a workout moves between phone and Watch.

When the gym changes, the plan can change with it
