Your phone is the timing gate. FPV Lap Timer uses your phone's camera to count laps automatically - no transponders, no timing gates, no extra hardware. Mount your phone at the start/finish, line the gate up with the on-screen center line, hit Start, and every time your quad crosses the line a lap is recorded. That's it. Built for FPV, tinywhoops, and drone racing practice, whether you're grinding a backyard gate or dialing in a full track.

About

Acro Flipbook

Features
Read full description

Acro Flipbook is a progression tracker for FPV freestyle. Seventy tricks in one dependency tree, so you always know what you can learn right now and what it unlocks next. THE TRICK TREE Every trick sits at its own depth, wired to what it needs. Tap one and the path lights up: all prerequisites, everything it opens, the rest dimmed. Three states only: locked, ready to learn, learned. "What to learn next" centres the simplest trick you can actually fly today. CATALOG Search by name or description, filter by status and by phase. Descriptions stay in pilot slang, not tutorial voice. TRICK CARDS Difficulty, prerequisites, what the trick unlocks, your own notes, and video references you can edit, delete, replace with your own, or reset to the originals in one tap. TRAINING PLAN Built for you: two or three new tricks you are actually ready for, easiest first, bookmarks in front, plus a solid run on whatever the journal says is still shaky. Or build it by hand from the trick card. Learned tricks drop out on their own. SESSION LOG When, where (sim or flight), what you trained and how it went: No luck / Progress / Solid, with a note per trick and one for the whole session. History shows up on the trick card, and after a solid run the app offers to mark the trick learned. 33 AWARDS Six groups: progress through the tree, closed phases, trick difficulty, the journal, consistency, and keeping your data in order. Locked awards show the condition and a progress bar, so you can see what they are for. Every award has its own artwork. OFFLINE, NO ACCOUNT The whole catalogue ships inside the app: 70 tricks, 129 prerequisite links, 41 video references. The internet is only needed to open a video. Progress, notes, journal, plan and awards stay on your device. No sign-up, no backend, no ads. Export and import everything through the clipboard.
