SmartAngle: product details

SmartAngle is an OEM product

SmartAngle is designed to be an OEM product - to be used or marketed by other companies under their own brand name or ours.

We do have a quantity of SmartAngles, as shown on this page, available for direct sales.

Please check the sales page for more details.

Smartangle is a Bluetooth digital level that talks to you via your smart phone!

Yes, it really talks - it reads out angles as well as displaying them. This makes it ideal when you are in one place moving something and your level is in another place where it is awkward to see.

Don't forget, to run the SmartAngle app you need Android 5.1 or later or Apple iOS 11 or later.

The SmartAngle Bluetooth module

The SmartAngle module is at the heart of the system and may be used stand-alone or as part of a digital level.

  • A "measure there, read here" Bluetooth level for your smart phone.
  • SmartAngle provides an extra hand when levelling.
  • SmartAngle is small enough (approx. 67mm wide x 41mm tall x 17mm deep) and light enough (less than 30g) to integrate into other projects or products to add digital levelling and angle measurement.
  • Please click here to read the SmartAngle User Guide.

The photo below shows SmartAngle used to set the angle of a bench saw blade. A stop was set at 45 degrees so SmartAngle could provide audible warning as the angle approached.

The photo below was taken by the SmartAngle app on an iPhone while measuring the fall of guttering using a prototype 150mm level. The app overlays the current reading onto the photo for reference.

The photo below shows how SmartAngle converts any magnetic spirit level into a highly accurate digital level. SmartAngle contains two rare earth magnets and will stick to any steel or magnetic surface.

SmartAngle is a leap forward

  • Bubble levels are tried and tested - fast and easy to use.
  • Digital levels provide an LCD display.
  • Apps can turn your phone into a level - as long as the phone edges are level, bases are flat and you are happy using your phone in places where you would take a level.
  • SmartAngle brings together the best of bubbles, digital levels and apps.

SmartAngle provides "measure there, read here" - you measure the level in one place and see the result in another - on your phone or tablet.

You need three hands if you are trying to hold a panel or door while screwing brackets in place while looking at the level - a one man job can rapidly become a two man job.

SmartAngle provides a third hand

  • Place it where you want to measure the level or angle,
  • Put your phone or tablet where you can see it - up to 10m (30 feet) away from SmartAngle.
  • Now you have both hands free to do the job.

Keep your eyes on the job, concentrate on the driver and the screw, don't bother to look at the level - SmartAngle provides audible feedback (tones and voice) to tell you if you are level (or at the correct angle) without having to look at the screen.

Create your own stops - angles you wish to use. If you want 33 degrees just enter it into the stop list. SmartAngle will tell you when you are approaching the required angle, leaving it or spot on it - it does this with a series of tones and beeps.


Technical features

  • Remote angle measurement for Apple iOS or Android phones/tablets.
  • Bluetooth (BLE 4.0) compatible.
  • Size: 52mm x 52mm x 67mm x 17mm.. Weight: 30g.
  • Power source: CR2032 battery - up to 2 year life on standby.
  • Single membrane switch to wake SmartAngle from deep sleep.
  • Power saving functions: user defined auto-timeout period - default 5 minutes. Auto turn off when app loses focus or is ended.
  • Two LEDs used to indicate power on (unconnected), Bluetooth connected and approaching required stop.
  • Unlimited digital stops: set the angles and the SmartAngle app tells you when you are there. An initial set of stops is provided: 0, 22.5, 30, 45, 60, 67.5, 90 - and 75.96 (4:1 ratio for safe ladder angle.)
  • Audible and visual warnings when the correct angle is reached - no need to look at the level - just wait for the "beep".
  • The tones used for warnings are adjustable - ideal for those who are losing their high frequency hearing.
  • Voice message to read out angles This feature may be turned on or off with one tap on the screen.
  • User-defined "voice stability time" - a reading must be stable for this time before the angle is read out. Default: 3 seconds.
  • Angles displayed in degrees, percentages (14.26%), ratios/falls/slopes (1:7), mm/m or in/ft. Tap the screen to change from one to another.
  • Selectable resolution. E.g. for degrees: 1, 1.5, 1.1.
  • Measures the difference between slopes - measure slope 1, measure slope 2, SmartAngle shows the angle between them.
  • Temporary zeroing function for measuring relative angles.
  • Step-by-step calibration instructions and diagrams shown on screen.
  • Two rare earth magnets (internal) hold the long side to metal surfaces.

The SmartAngle app

The Android version is suitable for Android 5.1 onwards.

The Apple version is suitable for iOS 11 onwards.

Please note this message from Apple.

"The following devices are not supported on iOS 11: original iPhone, iPhone 3G/3GS/4/4S/5/5c, original iPod touch, iPod touch 2nd-gen/3rd-gen/4th-gen/5th-gen, original iPad. iPad 2/3/4.18."

More about the SmartAngle app

The images below are screen grabs taken from the SmartAngle app running on an iPod.

The SmartAngle app runs under iOS (version 11 or later) and Android (version 5.1 or later).

Large characters make the display easy to see - no matter where you place your phone.

The "buttons" across the bottom (orange text on black background) provide immediate access to most SmartAngle functions.

The menu selector (three bars, top right) gives access to remaining settings.

The screen above shows the reading as a slope in millimetres per metre.

This shows the option selection screen.

The background can be selected from any of the colours here.

This screen allows configuration of voice messages and tone warnings.

The shows part of the calibration procedure.

Calibration takes under a minute and full details are provided in the User Guide.

Horizontal menu:

  • ZERO

    Temporarily zeros the angle display - for example, when measuring the difference between two slopes.

  • 0, 0.1, 0.05

    Selects display resolution: zero, one or two decimal places.

  • HOLD

    Holds the current reading - press again to continue.

    When hold is selected another button, "STORE" will store the current reading in th stops table.

  • STOPS

    Gives access to the stops table. Ideal for measuring an angle in one place and comparing it with a angle measured elsewhere. For example: aligning surfaces at the same angle.

Other options from the three-bar menu

  • CALIBRATION

    Gives access to the step-by-step calibration function.

  • COLOURS

    Selects the background colour for the screen.

  • OPTIONS

    Turns voice messages on or off.

    Sets the start/stop pitch for warning tones. Ideal for those of us who can't hear high frequencies as well as we used to.

  • USER GUIDE

    Goes online to display the User Guide.


SmartAngle retail packaging

SmartAngle is available in an attractive blister pack to fit standard Euro display panels.

The photograph below shows a small batch of SmartAngles ready for field testing.


Extra protection for SmartAngle

We have manufactured a batch of metal boxes to protect SmartAngle in your toolbox or workshop.

The boxes are embossed with the SmartAngle logo (paint would rub off in a toolbox) and SmartAngle is retained in place with a protective surround.


SmartAngle as a digital level

Obviously SmartAngle can be placed on top of any existing level to measure angles over longer distances.

Prototype level

QUS has manufactured a set of prototype aluminium extrusions to show how SmartAngle can become a digital level

A range of lengths would enable SmartAngle to meet any needs - from the shortest workshop level to the longest level for measuring falls.

The image below shows SmartAngle in a prototype 150mm level.

Key features of the prototype:

  • An internal steel strip holds SmartAngle in place magnetically.
  • Pre-drilled and countersunk 3mm holes so SmartAnglemay be fixed semi-permanently in place.
  • Horizontal or vertical operation - or anywhere between.
  • Magnetic strip on one side to hold the level securely against metal surfaces.
  • "V" grove on other side to align the level on the edge of vertical surfaces or pipe work.
  • Notches at both ends for fixing the level to pipework using rubber bands.
  • Triangular hole for hanging on a peg/nail in the workshop.
  • Could be available in different lengths - 150mm (6") or longer.

Smartangle: at the heart of digital levelling

This section shows how SmartAngle could be used at the heart of a family of digital levels.

QUS does not produce or sell such levels.

SmartAngle could fit levels of any length.

SmartAngle would offer:

  • twice the functionality of existing digital levels,
  • lower cost,
  • additional lengths at minimum cost,
  • more bang for your buck!

SmartAngle digital levels would work with the free SmartAngle app on your phone or tablet.

Comparing digital levels

The two digital levels shown below:

  • are 400mm long,
  • are accurate to 0.1 degrees,
  • buzz at 0, 45 and 90 degrees,
  • have solid aluminium frames,
  • display degrees in digital format,
  • operate over 360 degrees,
  • have a HOLD function,
  • display degrees, percentages and in/ft,
  • have memory recall.

However, the bottom one, the SmartAngle digital level:

  • would cost considerably less than the top one,
  • uses your Apple or Android smart phone or tablet as the display and for data entry,
  • has a very large digital readout,
  • provides voice readout of all measurements,

  • has an on-line User Guide and on-line support direct from your phone/tablet.

Integrating SmartAngle

Projects or products may be made "SmartAngle compatible" in three ways: magnetically, with a pocket or using screws.

Full details and drawings are provided on the projects page.


SmartAngle in action

The photograph below shows polygons cut using SmartAngle to set the saw blade angle.

The unglued polygons are laid out on a sheet of steel using magnets to hold the parts roughly in place. Obviously the joints tighten up fully when glued.

A simple jig was made to slide in the "T" slot to the left of the saw blade. A spring clamp holds a wooden block to set the length of each part and a toggle clamp secures a sacrificial piece of MDF which holds the timber in place and helps to prevent break out.

Other uses may be found on the projects page.


SmartAngle for model aircraft

Please see the projects page for details on how SmartAngle may be used to measure:

  • angle of incidence,
  • control surface throws,
  • engine down thrust and side thrust.
