For every engine the calculator covers, the main jet, clip position and air screw now come from the density of the air: temperature, pressure and humidity together. Put your engine through the calculator again and check the numbers against the ones in your notebook. Set the venturi on your setup. On a Rotax Pre-EVO, a setup's Jetting section holds the venturi, 8.5 or 12.5, with the needle and the floats, and the jetting calculator works from them. Next up on Home. Once Start here is done, Home suggests one thing to do next: the jetting for a race day in the next three days, a race day to plan, your tyre sets, or on Pro your first session. And bug fixes. ### 1.6.1 — 2026-10-12 Laps on every tyre set. Tyre sets count laps beside their heat cycles: tap + beside Laps on a set's card, or on the kart's mounted tyres for front and rear at once — and − takes laps back off. The tyres under every session. A telemetry import asks “Which tyres were on the kart?”, with their laps and heat cycles before the session, and can add the session's laps and a heat cycle to them. “Setup and tyres” on a session changes either afterwards. (Pro) Lap times by tyre age. On a set's card, see every timed lap against how far the set had run: how many laps it needs to come up to pace, its best lap and when, and the pace it loses per 10 laps. (Pro) Sessions by day. Switch the Telemetry list to “By day”, and narrow it to one track, or one day, from Filters. (Pro) What you changed between sessions. Compare two laps from different sessions, and “Setup changes” at the end shows what you changed on the kart in between: pressures, gearing, jetting. It covers sessions imported from now on. (Pro) And bug fixes. ### 1.6.0 — 2026-10-05 Import straight from a MyChron. Join your MyChron 5's Wi-Fi, tap Import session and choose “From a MyChron”: the logger's own sessions are listed by day with their best lap. Tick the ones you want, or “Select day” for a day's timed runs, and they import together — the kart and engine time asked once, each track saved once. No computer in between. (Pro) And bug fixes. ### 1.5.1 — 2026-10-02 See how you drove each corner. Tap a corner under “Where the time is” and it opens on its own page, its stretch drawn on the map, to show how each lap drove it: the hardest braking, where it came off the brake and where it got back on the power. The reasons name what cost the time — coasting before braking, staying on the brake longer, a slowest point that came late — each with something to try. With RPM on a kart without a gearbox, it also shows rear lock-up and wheelspin. (Pro) Every corner across the session: switch “Where the time is” to Every lap for what an ordinary lap gives away in each corner against your best there, how much that varies, and which lap did it best. The lap table marks warm-up and off-pace laps, and a likely tow. (Pro) Revs and gearing from your file: the revs at each corner's slowest point, where the engine pulls hardest on your own straights, and how close the straights come to the limit. On a kart without a gearbox, it estimates whether a tooth more or fewer on the rear would be quicker — something to test next session. (Pro) And bug fixes. ### 1.5.0 — 2026-09-30 See where each lap lost time. Open a session and, under the map, “Where the time is” names the corners that lap lost time in, costliest first — how much, and whether it went through the slowest point, slowing for the corner or on the straight after. Tap one and the map and the chart zoom onto it, mark where each lap started slowing and its slowest speed, and say what to try. In Compare laps, two laps get a bar for every corner, measured at the same places on the track. (Pro) Back up the whole garage: every kart, the spares on your shelf, tyre sets, gear, events, shopping, routines and telemetry go into one file. Restore it on your next phone — restoring doesn't need Pro. Compare two setups side by side on a kart's Presets tab, and see only the settings that differ. (Pro) With Imperial chosen in Settings, tyre pressures read in psi, speeds in mph and rollout, chain and geometry in inches — on the setup sheet, in the tools and in telemetry. Tap a tyre pressure or a sprocket and type the figure straight off your gauge. And bug fixes. ## Apps similar to KartGarage | App | Rating | Price | Category | | --- | --- | --- | --- | | [SetKART](https://appshunter.io/ios/app/setkart/id1496517352) | — | $7.99 | Sports | | [Ride Along with Friends](https://appshunter.io/ios/app/ride-along-with-friends/id6475593194) | — | Free | Sports | | [SetupKart Pro](https://appshunter.io/ios/app/setupkart-pro/id6761076873) | — | Free | Sports | | [Turbo Stopwatch](https://appshunter.io/ios/app/turbo-stopwatch/id6760888543) | — | Free | Sports | | [Roost MX - Maintenance/Setups](https://appshunter.io/ios/app/roost-mx-maintenancesetups/id6772153999) | — | Free | Sports | | [Jetting for DellOrto VHSB PRO](https://appshunter.io/ios/app/jetting-for-dellorto-vhsb-pro/id6477762438) | — | $9.99 | Sports | ## More apps by Dzmitry Kazhamiakin - [NapKit: Baby Sleep Tracker](https://appshunter.io/ios/app/napkit-baby-sleep-tracker/id6758158260) - [FeedKit: Baby Feeding Log](https://appshunter.io/ios/app/feedkit-baby-feeding-log/id6804222003) All apps by Dzmitry Kazhamiakin: https://appshunter.io/developer/1871223528 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
