Notebook, spreadsheet or app: which spotter logbook suits you?

At the fence a pencil is enough, at home the spreadsheet is waiting, on your smartphone an app – and at some point you wonder where your sightings actually belong. Notebook, spreadsheet or app is not a matter of faith but a trade-off between speed, robustness, analyzability and data security. This comparison shows you where each medium shines, where it fails and how to combine the strengths without fragmenting your collection.

The short answer

For logging at the fence, the notebook is the most robust tool, for analysis at the desk the spreadsheet is the most flexible, and for combining both – logging on the go, photo, location and collection in one – the app is the most convenient. If you only spot occasionally and analyze little, paper will serve you for a long time. If you want to know how many aircraft of a fleet you have already seen, you will sooner or later need a digital logbook.

More important than the medium, though, is the structure behind it. Which fields a sighting needs and why the registration is the key is explained in the basics article Documenting sightings: from notebook to digital logbook. Here the question is what you are best off keeping that structure in.

The notebook: robust, fast, but mute

The classic spotter notebook has a permanent place in the jacket pocket of many spotters, and for good reason. When three aircraft touch down on the runway in quick succession, you write down three registrations faster than you unlock a smartphone. No display glares in the sun, no battery drains in the cold, and nothing distracts you from the approach.

Strengths

• Speed in the moment: A registration like D-AINA is noted in two seconds. You can freely invent abbreviations and your own shorthand.
• Robustness: With a pencil, you can write even in drizzle and frost, where ballpoint pens like to fail and touchscreens become difficult with gloves.
• Independence: No network, no account, no update. A notebook works in every country and also at a spot without mobile reception.
• Sentimental value: A filled notebook with weather stains has a charm no file can match.

Weaknesses

• Not searchable: The most important spotter question – “Have I already seen this aircraft?” – you can only answer with long flipping once you pass a few hundred entries.
• No analysis: How many Airbus A320neos have you seen this year? On paper that means counting tally marks.
• Risk of loss: A notebook forgotten on the train, a wet backpack – and years of sightings are gone if there is no copy.
• No linking: Photos, camera timestamps and flight data stay separate from your notes.

The spreadsheet: maximally flexible, but only as good as your discipline

Excel, Google Sheets or LibreOffice Calc are the first step into the digital logbook for many. Every row is a sighting, every column a field – you do not need more database than that to begin with. Space is not a problem: Microsoft specifies 1,048,576 rows for an Excel worksheet, and Google Sheets allows up to 20 million cells per file. Even someone who stands at the fence every day will hardly fill that in a spotter’s lifetime.

Strengths

• Filtering and counting: With a filter, pivot table or a simple count formula, you immediately see how many registrations of an airline or a type you have collected. How to build annual statistics from that is shown in the article Analyzing your own spotting statistics.
• Full control: You decide on columns, spellings and colors yourself. An extra field for the serial number or the hex code is set up in seconds.
• Open formats: A spreadsheet can be exported as CSV at any time and brought into any other program. That makes it the best archive format.
• Free: Google Sheets and LibreOffice cost nothing, and Excel is installed on many computers anyway.

Weaknesses

• Free-text chaos: “A320N,” “A20N,” “Airbus A320neo” – three spellings, and your statistics count three different types. Without fixed dropdown lists, every spreadsheet falls apart over time.
• Tedious on the go: Maintaining a spreadsheet on a smartphone display while a Boeing 737-800 taxis past is no fun.
• Photos stay external: You can link pictures at best via file names or links.
• Double upkeep: If you work offline in Excel and on the go in a cloud copy, you risk two versions of the same file.

You will find a ready-made column structure with dropdown lists and validation formulas in the tutorial Setting up a spotting logbook in Excel or Google Sheets.

The app: convenient and connected, but tied to a provider

Spotter apps target exactly the weak points of paper and spreadsheets. Instead of free text, you choose type and airline from a list, the smartphone sets date and time automatically, and the photo is attached directly to the sighting. On top of that come functions that go beyond a pure logbook: wish lists, alerts for registrations you are looking for, or exchange with other spotters. The comparison Logbook apps for spotters gives an overview of different solutions.

Strengths

• Logging in one go: Photo, registration, type, airline, airport and spot end up in one entry – no gathering them up later.
• Consistent data: Dropdown lists prevent spelling variants. That makes counts and gap lists reliable.
• More than an archive: A wish list shows you what is still missing, and alerts tell you when an aircraft you are looking for is approaching.
• In sync on all devices: What you log at the fence is there on the computer in the evening.

Weaknesses

• Battery and network: With an empty battery or without reception at a remote spot, you depend on offline functions.
• Provider lock-in: If an app shuts down or lacks an export, your data is stuck.
• Less freedom: Not every app offers exotic extra fields that you can simply add in a spreadsheet.
• Distraction: Notifications and feeds are handy – but can distract you from the approach at the wrong moment.

The direct comparison

Criterion	Notebook	Spreadsheet (Excel, Sheets)	Spotter app
Speed at the fence	very high	low to medium	high
Robustness in weather	high (pencil)	depends on the device	depends on battery and device
Search “seen already?”	tedious	fast via filter	instant
Statistics and analysis	by hand only	very flexible	built in, but predefined
Consistent spelling	self-discipline	only with dropdown lists	through fixed lists
Linking photos	not possible	via file names/links	directly on the entry
Cost	low	mostly free	depends on the provider
Long-term archive	paper ages, no copy	open formats (CSV)	only with export
Exchange with others	not possible	share the file	community features

The table shows a typical pattern: the notebook scores at everything that happens in the moment, the spreadsheet at everything that happens later with the data, and the app sits in between and brings the social part.

Which logbook suits you?

The combination: how many experienced spotters work

In practice, many do not decide on a single medium at all. A division of labor in which each tool does what it does best has proven itself.

The second step benefits greatly from good photo data. If your pictures are already labeled with registrations, matching becomes routine – how that works is shown in the article Labeling photos properly. You can solve unreadable registrations in a picture with the tutorial Identifying an unreadable registration.

Switching: from paper or spreadsheet to a new medium

At some point the notebook gets too thick or the spreadsheet too confusing. A switch works if you tackle it in stages:

• Set spellings first: Before you transfer, define fixed names for types, airlines and spots. ICAO type designators and the official airline names are a good basis for this.
• From newest to oldest: Start with the last year. That quickly gives you a usable data basis, and the older, often patchier records follow bit by bit.
• Transfer unchanged: What you noted back then stays that way. You mark unclear details as uncertain instead of “correcting” them from memory.
• Keep the originals: The notebook goes on the shelf, not in the trash. Backed up as a photo, it serves as evidence in cases of doubt.
• Check old registrations: Aircraft change registers and registrations. If you run into inconsistencies while transferring, the tutorial Researching an aircraft’s history or a look at the fleet databases compared helps.

If you collect not only registrations but also visited airports or special liveries, you will find suitable field structures for these special collections in the articles Documenting visited airports and Collecting and documenting special liveries.

Common mistakes when choosing a logbook

• Switching the medium instead of improving the structure. A chaotic notebook does not become orderly in Excel. Fields first, then the tool.
• Keeping two main sources in parallel. If you maintain a spreadsheet and an app on equal footing, after a year you have two different versions.
• Separating photos and logbook. A picture without the registration in the file name or in the metadata is hard to match later.
• Not setting up an export. An app or a cloud account without a local backup is a risk for years of sightings.
• Too many fields. If you set up twenty columns at the beginning, after three weeks you no longer fill in any of them cleanly. Start with seven core fields and expand as needed.

Conclusion

Notebook, spreadsheet and app are not competitors but three tools with different strengths. The notebook wins at the fence when seconds count. The spreadsheet wins at the desk when you want to filter, count and design freely. The app connects logging, photo and collection and brings a wish list, alerts and community. Whichever you choose: with fixed fields, consistent spellings and a regular export, your collection stays intact across any change of medium.
