Every Summit release since launch, and what changed in each one. Updated whenever a new version reaches the App Store.
1.6.0
New
Share to Instagram Stories in one tap: redesigned, transparent and configurable stickers for an activity or your day's summary, including a version with no visible data (just the title and signature).
Improved
More precise power and load calculations: pauses count as rest, runs with power get their own reference, and your power profile makes better use of every effort. Some load figures may shift slightly.
The plan fits your day better: with only 30 minutes it can give you a compact quality session, and if you're not in shape for an FTP test, it swaps it for an easier session and reschedules the test that same week.
Coach assessments explain each activity with your own numbers.
New recovery trend chart, with zone bands and how many days you've spent in each one.
Faster: the app opens and switches tabs sooner and uses less data, and your Strava activities arrive sooner and with fewer interruptions.
Fixed
Your runs' details are kept until their metrics are complete, and Summit fetches any that are missing in the background.
The daily check-in (sick, injured, stressed…) starts fresh every morning.
The recovery card and your sleep score appear as soon as they're ready, always with last night's data.
Other minor fixes and stability improvements.
1.5.0
New
Compatible with iOS 27.
Sync with Garmin, Whoop or another device through intervals.icu and Summit now uses your full wellness data (HRV, resting HR, sleep, SpO2) to calculate Recovery without needing Apple Health.
More flexible season goals: pick your starting point during onboarding (a target race, building fitness, or maintaining) and change it anytime from Settings.
Redesigned race nutrition: an hour-by-hour plan, more precise carbohydrate, sodium and caffeine targets, per-stage calculations for multi-day events, and available offline on race day.
The Load card in Today now shows how hard you actually trained, compared with your recent history, instead of a confusing percentage; its detail view has been redesigned with a clear, deterministic summary.
The weekly strip and the heatmap now show compliance colours: green for completed, amber for partial, red for skipped.
Redesigned Effort Calculator: it's now easier to play with how hard you could go before blowing up.
New visual identity: refreshed typography and revised colours to meet accessibility contrast.
Fixed
Sleep score recalibrated to be more personal: it's now compared against your own history instead of penalising a night that's normal for you. Most people will see their score rise slightly.
The plan could bump a key session’s intensity (Threshold to VO2max, for example) just from a recovery improvement, even in weeks where it should never happen — and an adjustment could stay “stuck” after the condition that caused it stopped applying.
Your heart rate threshold (LTHR) resolved differently depending on the screen: some showed “--” with no HR zones even though the workout was still scored using it behind the scenes. It’s now consistent across the app, which shows which source it’s using.
The intervals.icu or Karoo connection could show as “disconnected” after signing out or reinstalling, silently stopping your workouts from reaching intervals.icu, Garmin or Zwift.
The “reconnect your integration” notice could appear even when the connection was working fine.
Route maps were missing on some Karoo activities.
One account's recovery data could briefly show up after switching to another account on the same device; it's now reliably cleared on sign-out.
Other minor fixes and stability improvements.
1.4.0
New
New sleep scoring engine, with an expanded detail view: comparison against your historical median, a sleep debt chart, stages and rhythm.
Recovery, Sleep and Load are now three separate cards in Today. The Recovery detail shows where today's value falls within your personal range, and coach insights read your trend over the past month, not just today's value.
New optional notifications, each with its own toggle in Settings: disconnected integration, fitness improvement, race reminder, weekly summary, and an ease-off alert after several days of low recovery.
Fixed
A double count of heart rate and HRV between Sleep and Recovery was distorting both scores.
Elevation, power or HR data was missing on some activities due to a caching issue.
Karoo activities without a power meter could lose the rest of their data (HR, elevation, speed, cadence).
A second recovery measurement in the morning could change your workout for no real reason.
A planned workout could change its duration or intensity on the same day.
Other minor fixes and stability improvements.
1.3.0
New
Completely redesigned onboarding: more visual and faster, with what Summit is for from the very first screen, and the option to enter your FTP if you want to.
A new power-record notification: when you beat your all-time best on any of the 16 durations on your power curve, we let you know.
Free users now see the outline of their plan (the type, duration and phase of each session), as a preview of the full planning.
Fixed
The “Structure” list in the workout detail showed the wrong zone or intensity on single-rep blocks.
The Analysis panel could come up empty when you opened an activity.
Karoo activities without power were saved without their charts.
The monthly calendar could show a workout that didn't exist on days with no availability.
Contradictory messages in Today during a rest day inside a taper.
The CP model curve could run outside the chart on the Power tab.
Other minor fixes and stability improvements.
1.2.0
New
Redesigned activity detail: tabbed navigation (Summary, HR, Power, Analysis), a route map in the header, and a visual comparison of planned versus executed, rep by rep, with your historical power curve as the reference.
Revamped special-event card (races, training camps, holidays): a weather forecast per stage (with heat warnings at ≥30°C and extreme heat at ≥35°C) and your race nutrition plan, with more context in the countdown and in the progress of multi-day events.
A new execution analysis based on the real laps recorded by your device, and more reliable for it: your easy rides and recovery spins now get an analysis too, not just interval sessions.
The Calendar now clearly distinguishes when you completed the workout, when you did part of it, and when you rode freely on a day with a workout scheduled.
A new share-card style with your route traced on it, a cover photo on outdoor rides, and a route thumbnail on the activity cards.
Wider free access: the route, the stats and the elevation in the activity detail are now visible without a subscription; heart rate, power and analysis stay in Pro or Elite.
When you complete the workout for a special event (your target race, for instance), you'll see a single combined card with the real result.
Improved
A smoother, faster Calendar, with no flicker when moving between months and days.
Usability improvements, including a more realistic anaerobic battery (W'bal) reading on long rides, cleaner elevation, power and HR charts, and an optional notice when a new version is available.
Fixed
Creating a special event, or certain plan settings, could wrongly erase the record of a workout you had already completed.
A free ride on a day with a workout scheduled could show an interval breakdown you hadn't actually done.
Today's workout could still show as pending even after you had completed it.
The execution chart (planned vs. completed) and the interval detail didn't appear on some Strava and Karoo activities.
A planned workout could disappear from the Calendar when you logged another, unrelated activity.
Other minor fixes and stability improvements.
1.1.0
New
Automatic sync with Hammerhead Karoo: your activities import themselves once you connect the device, every activity shows where it came from (Strava or Karoo), and your power curve and personal records stay consistent whatever the source.
Workouts exported to your device now include descriptions and instructions in Spanish or Catalan, following your phone's language.
Improved
A clearer Premium free trial: you now see the exact date your free access runs until, before anything is charged.
The weekly availability button has moved to the Calendar, next to add event, so you can edit it from where you can see the weeks it affects.
A clearer, simpler confidence indicator for your estimated FTP (eFTP).
Fixed
Activities that didn't show up in the day's calendar even though their dot did.
A blank activity detail when data from one of the sensors was missing.
Missing elevation profiles on older activities.
Incorrect power zones when exporting workouts to Karoo or intervals.icu.
When you didn't do the key workout, an alternative plan sometimes wasn't generated for the next day.
Other minor fixes and stability improvements.
1.0
New
Summit is on the App Store.
The daily recovery score and your sleep analysis are free from day one — a free tier, not a trial.
