Blok SessionsJoin the waitlist

Block out the season.

Blok Sessions is a training app for boulderers who plan their own training. Build each session from real training blocks, lay them into a multi-week plan, and tick them off as you go.

                      Drag a block from the tray onto any day, or select it and pick a day.

                      Seven periods. Use the ones this season needs.

                      A plan is a run of training periods, each with its own job. Every block in the catalog is tagged with the periods it suits, so a Power week doesn't fill up with endurance laps.

                      1. BaseBuild repeatable volume, movement quality and aerobic capacity.
                      2. StrengthIncrease pulling and finger strength with controlled load.
                      3. PowerDevelop explosive power, momentum and coordination.
                      4. Power EnduranceSustain power output across repeated hard efforts.
                      5. EnduranceExtend time on the wall with efficient movement.
                      6. PerformancePeak for outcomes with mental focus and route reading.
                      7. DeloadReduce load, restore tissue and mobility, stay moving.

                      The catalog: 206 blocks

                      Warm-ups, finger and pulling strength, power, endurance, technique drills and cool-downs. Each block has a prescription, a time, an intensity and the periods it suits. Missing one? Write your own.

                      Hands off the phone.

                      Guided sessions run the whole session for you: a timer per block, with work and rest rounds counted out loud on the screen. Hang, rest, repeat, and leave the phone on the mat.

                      Free to plan. Pro if you want the long game.

                      Questions

                      When does it launch?

                      There's no date yet. Join the waitlist and you'll get one email on the day it's on the App Store.

                      Who is it for?

                      Boulderers who already train on purpose. It assumes you know what a hangboard, a limit session and a deload are. Every block explains its prescription, but it won't tell you whether you're ready to hangboard.

                      Does it coach me?

                      No. There's no AI coach and no video analysis. You decide the plan. Pro's generator drafts a block from your goal, schedule and time budget, and you edit it from there.

                      Do I need an account?

                      No. Guest mode keeps everything on your phone. An account only adds a backup, so your log survives a new phone.

                      Android, or the web?

                      Launch is iPhone only. This website is set to grow into a web version for planning on a bigger screen.

                      How do I cancel Pro?

                      Subscriptions are managed by Apple, in your Apple ID settings. The one-time purchase never renews, so there's nothing to cancel.

                      Get it the day it's out.

                      One email when it's on the App Store, then your address is deleted. How we handle it.
