Invitation-only Android beta · iOS beta planned
THE CENTER OF SHOTDYNO
Ammo results.
Rifle context.
Open Compare Results from Home after signing in. Explore factory-ammo and handload results that members chose to publish. See ammunition, rifle setup and test conditions together; the collection grows as testers share more records.
- 01 / FIND
Choose the rifle context
Select a saved rifle to match recorded manufacturer, model and cartridge, or choose All Community rifles to explore more results.
- 02 / NARROW
Keep similar tests together
Use the available rifle, cartridge, barrel-length, distance and test-detail filters. Matches depend on what members have recorded and published.
- 03 / COMPARE
Select 2–4 results
Choose the published results you want to inspect, then select Compare selected. Review their measurements and recorded context side by side.
- Group size
- MOA
- Average velocity
- Velocity SD
- Velocity ES
SD is standard deviation; ES is extreme spread. On a phone, choose two result columns at a time. Wider screens can show all selected results side by side.
Comparison tip: Filter to the same test distance, or choose MOA: smallest first when viewing group angles across distances. MOA puts group size on an angular scale; shot count, conditions and measurement method still matter.
YOUR PRIVATE RESULTS
Factory Ammo vs Handload
In Results & History, choose at least two of your completed sessions for a separate private comparison. Review session cards with each session’s smallest recorded group in MOA, chronograph statistics and conditions.
Matching recorded details does not establish equivalent rifles or test conditions. Community results are User-submitted · Not verified. Compare observations in context; they do not establish a universal best choice or certify ammunition safety.
WHAT YOU CAN DO IN THE ANDROID BETA
Your records.
A clearer picture.
A place for the setup
Keep rifle, component, factory-ammo and equipment libraries. Enter details manually or take/import photos of factory-ammo, bullet, brass, powder or primer packaging for offline text reading. Review and correct every suggested field against the original label before saving; a scan is not a verified product identification. 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 .xls exports, LabRadar series CSV, MagnetoSpeed LOG.CSV, or mapped CSV/text. Review sessions, units and individual readings before confirming. For target photos, set a known-length scale, enter distance and mark impact centers to calculate group measurements, MOA and MRAD. Manual target-result entry remains available.
Make the results useful
Compare 2–4 published results in Community by recorded rifle and test context. Keep your own factory-ammo and handload comparisons private in Results & History. Group measurements, chronograph statistics and conditions help explain what was recorded.
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 supported photos between your own devices. Sync needs internet access and does not publish to Community. Automatic checks run while the app’s Home screen is open and 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
Browse Feed or Following, join discussions, like posts and follow replies in the in-app Replies inbox. You can attach one optional target photo to a discussion or performance post. 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; reports enter a moderation review queue.
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.
ANDROID FIRST · IOS TO FOLLOW
Android beta is live. Help shape the public release.
Invited testers can install ShotDyno through Google Play now. We’re testing real-phone behavior and gathering feedback before a public release.
Request access using the Google-account email you use in Google Play. We review requests individually, add selected testers to the tester list and email joining instructions. Submitting a request does not automatically unlock the download.
iOS testing through TestFlight is planned and is not open yet. We’ll announce availability when it’s ready. Community and private sync require internet access.
ANDROID BETA · INVITATION REQUESTS
Help test the comparison.
Request a beta invitation.
Help us test ammo comparisons with real range records. The invited Android beta is live through Google Play. Leave the Google-account email you use in Google Play; we review requests individually and email joining instructions to selected testers.
Beta invitation requests are for adults 18 and older. A request does not create a ShotDyno account or grant Google Play access, and selection is not guaranteed. iOS beta access is not open yet.
Request Android beta access

ABOUT THE INVITED BETA
Questions, answered.
How do I join the Android beta?
- Request an invitation using the email you sign in to Google Play with.
- If selected, you’ll receive an email after we add your account to the tester list.
- Open the emailed link while signed in to that Google account, join the test and install or update ShotDyno through Google Play.
The beta is invitation-only. Requests do not automatically grant access, and public downloads are not open.
Is the app finished?
ShotDyno is in beta. We’re testing real-phone behavior and collecting feedback before a public release. Features and screens may change as we improve the app; no public launch 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.
Is ShotDyno available on Android and iPhone?
The invited Android beta is available through Google Play. iPhone testing through TestFlight is planned and is not open yet. Request Android access with your Google-account email; selected testers receive joining instructions.
Is my Google Play login also a ShotDyno account?
They are separate. Use your invited Google account to join and download the beta. The local range notebook and package-photo text reading work without a ShotDyno account. To use Community, Compare Results or private sync, create a ShotDyno account in the app and complete email verification when prompted.
Why might Google Play show a temporary app name?
During Google’s first app review, the beta invitation page may show a temporary name. The installed app is ShotDyno. Use the joining instructions we email you to access the correct beta.
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/.xls, LabRadar series CSV, MagnetoSpeed LOG.CSV or mapped CSV/text. Environment observations, target-photo scale and 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.
How do I use Compare Results?
Sign in, open Compare Results from Home and choose a saved rifle or All Community rifles. A saved rifle matches recorded manufacturer, model and cartridge; additional filters help narrow the test context. Select 2–4 published results, then choose Compare selected. On a phone, select two result columns to view at a time. Results depend on what Community members have published.
Does a rifle match mean the tests are equivalent?
No. Matching recorded identity and filters helps you find relevant observations, but does not guarantee equivalent firearms or testing. 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. 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. Restoring replaces the destination’s local logbook, retains a recovery copy and disables automatic sync. Private sync and restore do not automatically merge conflicting logbooks.
What is allowed in Community?
Ordinary non-graphic firearm shooting, range observations and ammunition-performance discussions are welcome. Nudity, sexual content and graphic real-world violence or gore are prohibited. Members can use Report or Block; reports enter a human moderation review queue. Reporting does not automatically hide a post or verify its performance or safety.
How do I delete my ShotDyno account?
Use Account & Sync > Delete account in the app or the account-deletion page. Verify your own account to start automatic cloud-account deletion. Local device records and exported copies remain; read the deletion information before continuing.
How can I ask a question or request deletion of previous signup information?
Use the “Have a suggestion?” form below for questions, suggestions or privacy requests. Feedback is separate from invitation requests. To request Android beta access, use the dedicated invitation form.
