THE CENTER OF SHOTDYNO
Similar rifles.
Results you can compare.
Open Compare Results from Home after signing in. Rifle & Results Comparison brings published Community factory-ammo and handload results into one view.
- 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 measurement columns at a time. Wider screens can show all the comparison columns.
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.
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 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
Build 21. Private testing in progress.
Build 21 is in private testing, with an Android testing package prepared and an iOS development build installed. We’re preparing Google Play beta access first, with iOS TestFlight to follow after organization enrollment.
You can request an Android beta invitation below. Google Play testing and TestFlight downloads are not open through this site, and no release date has been announced. Community and private sync require internet access.
ANDROID BETA · INVITATION REQUESTS
Help test the comparison.
Request a beta invitation.
Help us test Compare Results with real range records. ShotDyno LLC is preparing a small, invited Android beta through Google Play. Leave your Google-account email so we can contact you when testing is ready.
This is an invitation request, not an app account or download. Requests do not guarantee selection or grant Google Play access. iOS TestFlight is planned after organization enrollment; no release date has been announced.

ABOUT THE DEVELOPMENT BUILD
Questions, answered.
Can I request access or download the app now?
You can request an Android beta invitation now. Requests are reviewed; they do not automatically grant access. Public downloads are not open. Selected testers will receive confirmed Google Play instructions when the test is ready.
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 can currently be downloaded through this site. Android invitation requests are open; confirmed access instructions will be sent to selected testers when testing is ready.
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 measurement 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 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. 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.
How can I ask a question or request deletion of previous signup information?
