v3.3.7
2026-11-07
Settings is now a full page with a Back button instead of a pop-up. Offline Mode is now a simple on/off switch. Fixed spacing so nothing hides behind the iPhone notch or home bar. When a new version is out, the app now loads fresh files instead of old saved ones.
v3.3.6
2026-11-03
Offline Mode now saves more. When you turn it on in Settings, GripGuide also saves the track list, your own logs and the Racer Data logs on your phone, so the Track Log and Racer Data work with no signal. Weak signal handling is also more reliable: slow requests give up sooner and use the saved copy. Fixed a glitch where scrolling inside Settings or other pop-ups could refresh or shift the page behind them.
v3.3.5
2026-11-02
Small wording cleanups (shorter Track Surface label, clearer hints) and more behind-the-scenes work so the live app and the test version share the same page.
v3.3.4
2026-11-02
Track Log works with no signal. Log a session at the track even when you have no service: your entry (photos included) is saved on your phone and sent automatically once you have signal again. The track picker and your own logs are also available offline. Editing and deleting entries still needs a connection.
v3.3.3
2026-11-01
Offline Mode now really works. Turn it on in Settings before you head somewhere with poor signal and GripGuide saves every tire photo, brand logo and the full tire and compound data to your phone, then uses those saved copies instead of waiting on the network. Even with Offline Mode off, the app now falls back to saved data when the signal is weak, and photos you have viewed stay saved through app updates.
v3.3.2
2026-11-01
Behind the scenes, the app's code now loads from a shared file too, so fixes land everywhere at once. Plus small wording cleanups in a few messages.
v3.3.1
2026-11-01
Phone layout tidy up: the top buttons sit on one row sized to their text, the filter area is a little tighter, and the Driver Skill buttons fit cleanly on one line. Behind the scenes, the app's styles now load from a shared file so fixes reach every version of the app at once.
v3.3.0
2026-10-22
New Entry redesigned as a guided step by step form so logging a session is quicker and easier on a phone. Every tire and track picker is now a full screen searchable list instead of the old dropdowns. Round type is now a simple pick list (Practice, Seeding, Qualifier, Main) and extra rounds collapse as you add them so the form stays short. Plus a round of layout and readability cleanups throughout.
v3.2.0
2026-10-19
Track Log: you can now log a different tire setup for each round of a race day. Turn on Per-Round mode in the New Entry form to add a block for every heat, qualifier, or main, each with its own tire, compound, front and rear stagger, star rating, and notes. Your race log then shows the full progression round by round. Single-tire logging still works exactly as before.
v3.1.0
2026-10-15
Track Log: new full-width track picker with built-in search, replaces the old dropdown so finding your track is faster, especially on mobile. Pop-up windows now size to your screen correctly and no longer jump or cut off while scrolling. Added the AKA Reverb and Pro-Line Vandal tires, plus the DIALED-RC V13 and V14. Compound chart cleaned up: brands are alphabetical and every brand reads softest to hardest.
v3.0.3
2026-08-10
Racer Data: see what other racers are running on your track conditions (requires free account). Tire Bag sync across devices with an account. Driver Skill picker on race log entries. Surface condition picker replaces free-text on logs and tire submissions. Photo gallery browsing + auto-resize. Anti-spam honeypot on all forms. Admin panel fully migrated to tires.json.
v3.0.2
2026-07-27
Track log entries grouped by Date or Track with collapsible sections. Star ratings more visible in dark mode. Track log surface condition picker (17 standardized values). Photo browsing from gallery. Auto-resize before upload.
v3.0.1
2026-07-27
