ONE NOTEBOOK. BOTH SIDES OF THE RECORD.
Factory Ammo vs Handload.
Your measured results, together.
Bring completed factory-ammo and handload sessions into one comparison, with recorded group measurements, chronograph statistics and environment data in view.
HANDLOAD
Keep the batch in context
Your batch record connects rifle and component details to the observations saved during its session.
Compare recorded observations, with the context behind each result. Measurements describe individual tests; they do not establish a universal best choice or certify ammunition safety.
INSIDE THE PRIVATE TEST BUILD · 1.0.0+21
Your records.
A clearer picture.
A place for the setup
Keep rifle, component, factory-ammo and equipment libraries. Enter package details manually or take/import package photos for offline text reading. Review every suggested field against the original label before saving. Prepare a handload batch or factory-ammo test, then carry the setup into an Active Session.
More than a group size
Enter measured chronograph velocities or import supported Garmin ShotView CSV/text and Excel .xls exports. Review sessions, units and individual readings before confirming. Record conditions and use manually marked target photos for group measurements, MOA and MRAD. Manual target-result entry remains available.
Factory meets handload
Keep a private Factory Ammo catalog with product identity and lot notes. Start factory-ammo tests with a saved rifle, then compare completed factory and handload sessions side by side in Results & History using your own measured observations.
Ready when the signal isn’t
Rifles, catalogs, batches, range observations, targets and history stay usable offline. Save drafts and resume Active Sessions. Portable export and restore let you keep recovery copies; exports contain private unencrypted logbook data, so choose private storage and review carefully before restoring.
Sync between your devices
Sign in and confirm logbook ownership to sync private records and target images between your own devices. Sync needs internet access and does not publish to Community. Automatic checks pause during editing or conflicts; review conflicting copies rather than assuming an automatic merge. Anyone using an unlocked device can open its local logbook.
Share with context
Explore Community posts and share measured observations with signed-in members. Choose the content, review it and select Publish; private logbook records remain separate from published copies. Publishing requires a verified email and unrestricted account. Members can report content and block authors; human moderation handles reported content.

Community performance data is User-submitted · Not verified and not manufacturer verified. Results vary by firearm, ammunition lot, components, dimensions, conditions, shooter and test method. Reports and moderation do not verify performance, certify safety or recommend ammunition. ShotDyno records observations; Community results, charge weights and app examples are not loading instructions. Independently follow current published reloading manuals and component/firearm manufacturers’ instructions.

ABOUT THE DEVELOPMENT BUILD
Questions, answered.
Can I sign up or download the app now?
No. Public beta applications and downloads are closed. We will update this site once Google Play testing is ready and active, with confirmed access details.
Is the app finished?
No. This site describes the ShotDyno 1.0.0+21 private test build. Android testing and preparation for Google Play beta access continue. Features and screens may change, and no release date has been announced.
Is this only for handload records?
No. Factory Ammo has its own catalog and testing records. Completed factory-ammo and handload sessions can appear together in measured comparisons in Results & History.
Which platforms are being developed?
Build 21 has an Android testing package and an iOS development build for private testing. Google Play beta access is being prepared first, followed by iOS through TestFlight. Neither store beta is currently available through this site. Confirmed access details will be added when testing opens.
Does it work at the range without a signal?
The core range notebook is local-first: rifle and component records, batches, Active Sessions, targets and history work offline. Account services, private sync and Community require internet access.
Are my records automatically shared?
No. Optional private sync does not publish to Community. You choose what to share, review it and select Publish before it becomes visible to signed-in members. Members can report content and block authors. Your local logbook is accessible to anyone using your unlocked device.
Are measurements captured automatically?
Chronograph readings can be entered manually or imported from supported Garmin ShotView CSV/text and .xls files. Environment observations and target-photo impact marks are entered manually. Review imported and photo-derived values against the original source. Direct wireless/FIT connections, .xlsx import, automatic weather lookup and automatic impact detection are not current features.
What does Match My Rifle show?
Community-submitted factory-ammo performance from similar rifle configurations. Data is user-submitted, not manufacturer verified. Results vary by firearm, ammunition lot, components, dimensions, conditions, shooter and test method. Reports and moderation do not certify performance or safety.
How do backup and recovery work?
Portable export and restore are available in the beta candidate. Exports contain private unencrypted logbook data; keep them in private storage. Review the source and destination before restoring, retain wanted recovery copies and avoid overwriting newer work. Private sync and restore do not automatically merge conflicting logbooks.
How can I ask a question or request deletion of previous signup information?
